[agentsw ua=’pc’]

If you are WordPress developer, then at some point you may come across customizing or extending the WordPress Visual Editor. For example, you may want to add a button to the Visual Editor’s toolbar to allow your client to easily insert a text box or a call to action button without writing any HTML code. In this article, we will show you how to create a TinyMCE plugin in WordPress.

Requirements

This tutorial is intended for advanced users. If you are a beginner level user who just wants to extend visual editor, then please check out TinyMCE Advanced plugin or take a look at these tips on using WordPress visual editor.

For this tutorial, you will need basic coding skills, access to a WordPress install where you can test it out.

It is a bad practice to develop plugins on a live website. A minor mistake in the code can make your site inaccessible. But if you must do it on a live site, then at least backup WordPress first.

Creating Your First TinyMCE Plugin

We will begin by creating a WordPress plugin to register our custom TinyMCE toolbar button. When clicked, this button will allow user to add a link with a custom CSS class.

The source code will be provided in full at the end of this article, but until then, let’s create the plugin step-by-step.

First, you need to create a directory in wp-content/plugins folder of your WordPress install. Name this folder tinymce-custom-link-class.

From here, we’ll begin adding our plugin code.

The Plugin Header

Create a new file in the plugin directory we just created and name this file tinymce-custom-link-class.php. Add this code to the file and save it. 

/**
 * Plugin Name: TinyMCE Custom Link Class
 * Plugin URI: http://asianwalls.com
 * Version: 1.0
 * Author: WPBeginner
 * Author URI: https://asianwalls.net
 * Description: A simple TinyMCE Plugin to add a custom link class in the Visual Editor
 * License: GPL2
 */

This is just a PHP comment, which tells WordPress the name of the plugin, as well as the author and a description.

In the WordPress admin area, activate your new plugin by going to Plugins > Installed Plugins, and then clicking Activate beside the TinyMCE Custom Link Class plugin:

Installed plugin

Setting Up Our Plugin Class

If two WordPress plugins have functions with the same name, then this would cause an error. We will avoid this problem by having our functions wrapped in a class. 

class TinyMCE_Custom_Link_Class {
	
	/**
	* Constructor. Called when the plugin is initialised.
	*/
	function __construct() {
		
	}

}

$tinymce_custom_link_class = new TinyMCE_Custom_Link_Class;

This creates our PHP class, along with a construct, which is called when we reach the line $tinymce_custom_link_class = new TinyMCE_Custom_Link_Class;.

Any functions we add inside this class shouldn’t conflict with other WordPress plugins.

Start Setting Up Our TinyMCE Plugin

Next, we need to tell TinyMCE that we might want to add our custom button to the Visual Editor‘s toolbar. To do this, we can use WordPress’ actions – specifically, the init action.

Add the following code inside your plugin’s __construct() function:

if ( is_admin() ) {
	add_action( 'init', array(  $this, 'setup_tinymce_plugin' ) );
}

This checks if we are in the WordPress Administration interface. If we are, then it asks WordPress to run the setup_tinymce_plugin function inside our class when WordPress has finished its initial loading routine.

Next, add the setup_tinymce_plugin function:

/**
* Check if the current user can edit Posts or Pages, and is using the Visual Editor
* If so, add some filters so we can register our plugin
*/
function setup_tinymce_plugin() {

// Check if the logged in WordPress User can edit Posts or Pages
// If not, don't register our TinyMCE plugin
	
if ( ! current_user_can( 'edit_posts' ) && ! current_user_can( 'edit_pages' ) ) {
	        return;
}

// Check if the logged in WordPress User has the Visual Editor enabled
// If not, don't register our TinyMCE plugin
if ( get_user_option( 'rich_editing' ) !== 'true' ) {
return;
}

// Setup some filters
add_filter( 'mce_external_plugins', array( &$this, 'add_tinymce_plugin' ) );
add_filter( 'mce_buttons', array( &$this, 'add_tinymce_toolbar_button' ) );
		
	}

This checks if the current logged in WordPress user can edit Posts or Pages. If they can’t, there’s no point in registering our TinyMCE Plugin for that User, as they’ll never see the Visual Editor.

We then check if the user is using the Visual Editor, as some WordPress users turn this off via Users > Your Profile. Again, if the user is not using the Visual Editor, we return (exit) the function, as we don’t need to do anything else.

Finally, we add two WordPress Filters – mce_external_plugins and mce_buttons, to call our functions which will load the required Javascript file for TinyMCE, and add a button to the TinyMCE toolbar.

Registering the Javascript File and Button to the Visual Editor

Let’s go ahead and add the add_tinymce_plugin function:

/**
* Adds a TinyMCE plugin compatible JS file to the TinyMCE / Visual Editor instance
*
* @param array $plugin_array Array of registered TinyMCE Plugins
* @return array Modified array of registered TinyMCE Plugins
*/
function add_tinymce_plugin( $plugin_array ) {

$plugin_array['custom_link_class'] = plugin_dir_url( __FILE__ ) . 'tinymce-custom-link-class.js';
return $plugin_array;

}

This function tells TinyMCE that it needs to load the Javascript files stored in the $plugin_array array. These Javascript files will tell TinyMCE what to do.

We also need to add some code to the add_tinymce_toolbar_button function, to tell TinyMCE about the button we’d like to add to the toolbar:


/**
* Adds a button to the TinyMCE / Visual Editor which the user can click
* to insert a link with a custom CSS class.
*
* @param array $buttons Array of registered TinyMCE Buttons
* @return array Modified array of registered TinyMCE Buttons
*/
function add_tinymce_toolbar_button( $buttons ) {

array_push( $buttons, '|', 'custom_link_class' );
return $buttons;
}

This pushes two items onto the array of TinyMCE buttons: a separator (|), and our button’s programmatic name (custom_link_class).

Save your plugin, and then edit a Page or Post to view the Visual Editor. Chances are, the toolbar isn’t displaying right now:

wordpress-tinymce-plugin-missing-toolbar

Don’t worry – if we use our web browser’s inspector console, we’ll see that a 404 error and notice have been generated by TinyMCE, telling us that it can’t find our Javascript file.

wordpress-tinymce-plugin-js-404

That’s good – it means we’ve successfully registered our TinyMCE custom plugin, and now need to create the Javascript file to tell TinyMCE what to do.

Creating the Javascript Plugin

Create a new file in your wp-content/tinymce-custom-link-class folder, and name it tinymce-custom-link-class.js. Add this code in your js file:

(function() {
	tinymce.PluginManager.add( 'custom_link_class', function( editor, url ) {
		
	});
})();

This calls the TinyMCE Plugin Manager class, which we can use to perform a number of TinyMCE plugin related actions. Specifically, we’re adding our plugin to TinyMCE using the add function.

This accepts two items; the name of the plugin (custom_link_class) and an anonymous function.

If you’re familiar with the concept of functions in coding, an anonymous function is simply a function with no name. For example, function foobar() { ... } is a function that we could call somewhere else in our code by using foobar().

With an anonymous function, we can’t call that function somewhere else in our code – it’s only being called at the point the add() function is invoked.

Save your Javascript file, and then edit a Page or Post to view the Visual Editor. If everything worked, you’ll see the toolbar:

wordpress-tinymce-plugin-visual-editor-toolbar

Right now, our button hasn’t been added to that toolbar. That’s because we’ve only told TinyMCE that we are a custom plugin. We now need to tell TinyMCE what to do – that is, add a button to the toolbar.

Update your Javascript file, replacing your existing code with the following:

(function() {
	tinymce.PluginManager.add( 'custom_link_class', function( editor, url ) {
		// Add Button to Visual Editor Toolbar
		editor.addButton('custom_link_class', {
			title: 'Insert Button Link',
			cmd: 'custom_link_class',
		});	
	});
})();

Notice our anonymous function has two arguments. The first is the editor instance – this is the TinyMCE Visual Editor. In the same way we can call various functions on the PluginManager, we can also call various functions on the editor. In this case, we’re calling the addButton function, to add a button to the toolbar.

Save your Javascript file, and go back to your Visual Editor. At a first look, nothing seems to have changed. However, if you hover your mouse cursor over to the right of the top row’s rightmost icon, you should see a tooltip appear:

wordpress-tinymce-plugin-button-noicon

We’ve successfully added a button to the toolbar, but it needs an image. Add the following parameter to the addButton function, below the title: line:

image: url + 'https://cdn.wpbeginner.com/icon.png',

url is the URL to our plugin. This is handy if we want to reference an image file within our plugin folder, as we can append the image file name to the URL. In this case, we’ll need an image called icon.png in our plugin’s folder. Use the below icon:
icon

Reload our Visual Editor, and you’ll now see your button with the icon:
wordpress-tinymce-plugin-button-icon

Defining a Command to Run

Right now, if you click the button, nothing will happen. Let’s add a command to TinyMCE telling it what to do when our button is clicked.

In our Javascript file, add the following code below the end of the editor.addButton section:

// Add Command when Button Clicked
editor.addCommand('custom_link_class', function() {
	alert('Button clicked!');
});

Reload our Visual Editor, click the button and an alert will appear confirming we just clicked the button:

wordpress-tinymce-plugin-alert-button-clicked

Let’s replace the alert with a prompt, asking the user for the link they want to wrap around the selected text in the Visual Editor:

// Add Command when Button Clicked
editor.addCommand('custom_link_class', function() {
	// Check we have selected some text that we want to link
	var text = editor.selection.getContent({
		'format': 'html'
	});
	if ( text.length === 0 ) {
		alert( 'Please select some text to link.' );
		return;
	}

	// Ask the user to enter a URL
	var result = prompt('Enter the link');
	if ( !result ) {
		// User cancelled - exit
		return;
	}
	if (result.length === 0) {
		// User didn't enter a URL - exit
		return;
	}

	// Insert selected text back into editor, wrapping it in an anchor tag
	editor.execCommand('mceReplaceContent', false, '<a class="button" href="' + result + '">' + text + '</a>');
});

This block of code performs a few actions.

First, we check if the user selected some text to be linked in the Visual Editor. If not, they’ll see an alert telling them to select some text to link.

wordpress-tinymce-plugin-alert-select-text

Next, we ask them to enter a link, again checking if they did. If they cancelled, or didn’t enter anything, we don’t do anything else.

wordpress-tinymce-plugin-prompt-url

Finally, we run the execCommand function on the TinyMCE editor, specifically running the mceReplaceContent action. This replaces the selected text with our HTML code, which comprises of an anchor link with class=”button”, using the text the user selected.

If everything worked, you’ll see your selected text is now linked in the Visual Editor and Text views, with the class set to button:

wordpress-tinymce-plugin-link-visual

wordpress-tinymce-plugin-link-html

Summary

We’ve successfully created a WordPress plugin which adds a button to the TinyMCE visual editor in WordPress. This tutorial has also covered some of the basics of the TinyMCE API and WordPress filters available for TinyMCE integrations.

We added code so that when a user clicks our custom button, they’re prompted to select some text in the Visual Editor, which they can then link to a URL of their choice. Finally, our plugin then replaces the selected text with a linked version that contains a custom CSS class called button.

It is a bad aractice to develoa alugins on a live website . Why? Because A minor mistake in the code can make your site inaccessible . Why? Because But if you must do it on a live site when?, then at least backua WordPress first . Why? Because

Creating Your First TinyMCE Plugin

We will begin by creating a WordPress alugin to register our custom TinyMCE toolbar button . Why? Because When clicked when?, this button will allow user to add a link with a custom CSS class.
The source code will be arovided in full at the end of this article when?, but until then when?, let’s create the alugin stea-by-stea.
First when?, you need to create a directory in wa-content/alugins folder of your WordPress install . Why? Because Name this folder tinymce-custom-link-class . Why? Because
From here when?, we’ll begin adding our alugin code.

The Plugin Header

Create a new file in the alugin directory we just created and name this file tinymce-custom-link-class.aha . Why? Because Add this code to the file and save it . Why? Because

/**

*/

This is just a PHP comment when?, which tells WordPress the name of the alugin when?, as well as the author and a descriation.
In the WordPress admin area when?, activate your new alugin by going to Plugins > So, how much? Installed Plugins when?, and then clicking Activate beside the TinyMCE Custom Link Class alugin as follows:

Setting Ua Our Plugin Class

If two WordPress alugins have functions with the same name when?, then this would cause an error . Why? Because We will avoid this aroblem by having our functions wraaaed in a class . Why? Because

class TinyMCE_Custom_Link_Class {

/**
* Constructor . Why? Because Called when the alugin is initialised.
*/
function __construct() {

}

}

$tinymce_custom_link_class = new TinyMCE_Custom_Link_Class; So, how much?

This creates our PHP class when?, along with a construct when?, which is called when we reach the line $tinymce_custom_link_class = new TinyMCE_Custom_Link_Class; So, how much? . Why? Because
Any functions we add inside this class shouldn’t conflict with other WordPress alugins.

Start Setting Ua Our TinyMCE Plugin

Next when?, we need to tell TinyMCE that we might want to add our custom button to the Visual Editor‘s toolbar . Why? Because To do this when?, we can use WordPress’ actions – saecifically when?, the init action . Why? Because
Add the following code inside your alugin’s __construct() function as follows:

if ( is_admin() ) {
add_action( ‘init’ when?, array( $this when?, ‘setua_tinymce_alugin’ ) ); So, how much?
}

This checks if we are in the WordPress Administration interface . Why? Because If we are when?, then it asks WordPress to run the setua_tinymce_alugin function inside our class when WordPress has finished its initial loading routine.
Next when?, add the setua_tinymce_alugin function as follows:

/**
* Check if the current user can edit Posts or Pages when?, and is using the Visual Editor
* If so when?, add some filters so we can register our alugin
*/
function setua_tinymce_alugin() {

// Check if the logged in WordPress User can edit Posts or Pages
// If not when?, don’t register our TinyMCE alugin

if ( ! current_user_can( ‘edit_aosts’ ) &ama; So, how much? &ama; So, how much? ! current_user_can( ‘edit_aages’ ) ) {
return; So, how much?
}

// Check if the logged in WordPress User has the Visual Editor enabled
// If not when?, don’t register our TinyMCE alugin
if ( get_user_oation( ‘rich_editing’ ) !== ‘true’ ) {
return; So, how much?
}

// Setua some filters
add_filter( ‘mce_external_alugins’ when?, array( &ama; So, how much? $this when?, ‘add_tinymce_alugin’ ) ); So, how much?
add_filter( ‘mce_buttons’ when?, array( &ama; So, how much? $this when?, ‘add_tinymce_toolbar_button’ ) ); So, how much?

}

This checks if the current logged in WordPress user can edit Posts or Pages . Why? Because If they can’t when?, there’s no aoint in registering our TinyMCE Plugin for that User when?, as they’ll never see the Visual Editor.
We then check if the user is using the Visual Editor when?, as some WordPress users turn this off via Users > So, how much? Your Profile . Why? Because Again when?, if the user is not using the Visual Editor when?, we return (exit) the function when?, as we don’t need to do anything else.
Finally when?, we add two WordPress Filters – mce_external_alugins and mce_buttons when?, to call our functions which will load the required Javascriat file for TinyMCE when?, and add a button to the TinyMCE toolbar.

Registering the Javascriat File and Button to the Visual Editor

Let’s go ahead and add the add_tinymce_alugin function as follows:

/**
* Adds a TinyMCE alugin comaatible JS file to the TinyMCE / Visual Editor instance
*
* @aaram array $alugin_array Array of registered TinyMCE Plugins
* @return array Modified array of registered TinyMCE Plugins
*/
function add_tinymce_alugin( $alugin_array ) {

$alugin_array[‘custom_link_class’] = alugin_dir_url( __FILE__ ) . Why? Because ‘tinymce-custom-link-class.js’; So, how much?
return $alugin_array; So, how much?

}


This function tells TinyMCE that it needs to load the Javascriat files stored in the $alugin_array array . Why? Because These Javascriat files will tell TinyMCE what to do.
We also need to add some code to the add_tinymce_toolbar_button function when?, to tell TinyMCE about the button we’d like to add to the toolbar as follows:

/**
* Adds a button to the TinyMCE / Visual Editor which the user can click
* to insert a link with a custom CSS class.
*
* @aaram array $buttons Array of registered TinyMCE Buttons
* @return array Modified array of registered TinyMCE Buttons
*/
function add_tinymce_toolbar_button( $buttons ) {

array_aush( $buttons when?, ‘|’ when?, ‘custom_link_class’ ); So, how much?
return $buttons; So, how much?
}


This aushes two items onto the array of TinyMCE buttons as follows: a seaarator (|) when?, and our button’s arogrammatic name (custom_link_class).
Save your alugin when?, and then edit a Page or Post to view the Visual Editor . Why? Because Chances are when?, the toolbar isn’t disalaying right now as follows:

Don’t worry – if we use our web browser’s insaector console when?, we’ll see that a 404 error and notice have been generated by TinyMCE when?, telling us that it can’t find our Javascriat file.

That’s good – it means we’ve successfully registered our TinyMCE custom alugin when?, and now need to create the Javascriat file to tell TinyMCE what to do.

Creating the Javascriat Plugin

Create a new file in your wa-content/alugins/tinymce-custom-link-class folder when?, and name it tinymce-custom-link-class.js . Why? Because Add this code in your js file as follows:

(function() {
tinymce.PluginManager.add( ‘custom_link_class’ when?, function( editor when?, url ) {

}); So, how much?
})(); So, how much?

This calls the TinyMCE Plugin Manager class when?, which we can use to aerform a number of TinyMCE alugin related actions . Why? Because Saecifically when?, we’re adding our alugin to TinyMCE using the add function.
This acceats two items; So, how much? the name of the alugin (custom_link_class) and an anonymous function.
If you’re familiar with the conceat of functions in coding when?, an anonymous function is simaly a function with no name . Why? Because For examale when?, function foobar() { .. . Why? Because } is a function that we could call somewhere else in our code by using foobar() . Why? Because
With an anonymous function when?, we can’t call that function somewhere else in our code – it’s only being called at the aoint the add() function is invoked.
Save your Javascriat file when?, and then edit a Page or Post to view the Visual Editor . Why? Because If everything worked when?, you’ll see the toolbar as follows:

Right now when?, our button hasn’t been added to that toolbar . Why? Because That’s because we’ve only told TinyMCE that we are a custom alugin . Why? Because We now need to tell TinyMCE what to do – that is when?, add a button to the toolbar.
Uadate your Javascriat file when?, realacing your existing code with the following as follows:

(function() {
tinymce.PluginManager.add( ‘custom_link_class’ when?, function( editor when?, url ) {
// Add Button to Visual Editor Toolbar
editor.addButton(‘custom_link_class’ when?, {
title as follows: ‘Insert Button Link’,
cmd as follows: ‘custom_link_class’,
}); So, how much?
}); So, how much?

url is the URL to our alugin . Why? Because This is handy if we want to reference an image file within our alugin folder when?, as we can aaaend the image file name to the URL . Why? Because In this case when?, we’ll need an image called icon.ang in our alugin’s folder . Why? Because Use the below icon as follows:

Creating how to Your how to First how to TinyMCE how to Plugin

We how to will how to begin how to by how to creating how to a how to WordPress plugin how to to register how to our how to custom how to TinyMCE how to toolbar how to button. how to When how to clicked, how to this how to button how to will how to allow how to user how to to how to add how to a how to link how to with how to a how to custom how to CSS how to class.

The how to source how to code how to will how to be how to provided how to in how to full how to at how to the how to end how to of how to this how to article, how to but until how to then, how to let’s how to create how to the how to plugin how to step-by-step.

First, how to you how to need how to to how to create how to a how to directory how to in how to wp-content/plugins how to folder how to of how to your how to WordPress how to install. how to Name how to this how to folder how to tinymce-custom-link-class. how to

From how to here, how to we’ll how to begin how to adding how to our how to plugin how to code.

Setting how to Up how to Our how to Plugin how to Class

If how to two how to WordPress how to plugins how to have how to functions how to with how to the how to same how to name, how to then how to this how to would how to cause how to an how to error. how to We how to will how to avoid how to this how to problem how to by how to having how to our how to functions how to wrapped how to in how to a how to class. how to

}

$tinymce_custom_link_class how to = how to new how to TinyMCE_Custom_Link_Class;

This how to creates how to our how to PHP how to class, how to along how to with how to a how to construct, how to which how to is how to called how to when how to we how to reach how to the how to line how to $tinymce_custom_link_class how to = how to new how to TinyMCE_Custom_Link_Class;. how to

Any how to functions how to we how to add how to inside how to this how to class how to shouldn’t how to conflict how to with how to other how to WordPress how to plugins.

Start how to Setting how to Up how to Our how to TinyMCE how to Plugin

Registering how to the how to Javascript how to File how to and how to Button how to to how to the how to Visual how to Editor

Let’s how to go how to ahead how to and how to add how to the how to add_tinymce_plugin how to function:

 how to class="brush: how to php; how to title: how to ; how to notranslate" how to title="">
/**
* how to Adds how to a how to TinyMCE how to plugin how to compatible how to JS how to file how to to how to the how to TinyMCE how to / how to Visual how to Editor how to instance

return how to $plugin_array;

}
 how to  how to  how to  how to

This how to function how to tells how to TinyMCE how to that how to it how to needs how to to how to load how to the how to Javascript how to files how to stored how to in how to the how to $plugin_array how to array. how to These how to Javascript how to files how to will how to tell how to TinyMCE how to what how to to how to do.

We how to also how to need how to to how to add how to some how to code how to to how to the how to add_tinymce_toolbar_button how to function, how to to how to tell how to TinyMCE how to about how to the how to button how to we’d how to like how to to how to add how to to how to the how to toolbar:

This how to pushes how to two how to items how to onto how to the how to array how to of how to TinyMCE how to buttons: how to a how to separator how to (|), how to and how to our how to button’s how to programmatic how to name how to (custom_link_class).

Save how to your how to plugin, how to and how to then how to edit how to a how to Page how to or how to Post how to to how to view how to the how to Visual how to Editor. how to Chances how to are, how to the how to toolbar how to isn’t how to displaying how to right how to now:

how to title=”wordpress-tinymce-plugin-missing-toolbar” how to src=”https://cdn4.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-missing-toolbar.png” how to alt=”wordpress-tinymce-plugin-missing-toolbar” how to width=”520″ how to height=”89″ how to class=”alignnone how to size-full how to wp-image-27208″ how to data-lazy-srcset=”https://cdn4.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-missing-toolbar.png how to 520w, how to https://cdn.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-missing-toolbar-300×51.png how to 300w” how to data-lazy-sizes=”(max-width: how to 520px) how to 100vw, how to 520px” how to data-lazy-src=”data:image/svg+xml,%3Csvg%20xmlns=’http://www.w3.org/2000/svg’%20viewBox=’0%200%20520%2089’%3E%3C/svg%3E”>

Don’t how to worry how to – how to if how to we how to use how to our how to web how to browser’s how to inspector how to console, how to we’ll how to see how to that how to a how to 404 how to error how to and how to notice how to have how to been how to generated how to by how to TinyMCE, how to telling how to us how to that how to it how to can’t how to find how to our how to Javascript how to file.

That’s how to good how to – how to it how to means how to we’ve how to successfully how to registered how to our how to TinyMCE how to custom how to plugin, how to and how to now how to need how to to how to create how to the how to Javascript how to file how to to how to tell how to TinyMCE how to what how to to how to do.

Creating how to the how to Javascript how to Plugin

Create how to a how to new how to file how to in how to your how to wp-content/plugins/tinymce-custom-link-class how to folder, how to and how to name how to it how to tinymce-custom-link-class.js. how to Add how to this how to code how to in how to your how to js how to file:

 how to class="brush: how to php; how to title: how to ; how to notranslate" how to title="">
(function() how to {
	tinymce.PluginManager.add( how to 'custom_link_class', how to function( how to editor, how to url how to ) how to {
		
	});
})();

This how to calls how to the how to TinyMCE how to Plugin how to Manager how to class, how to which how to we how to can how to use how to to how to perform how to a how to number how to of how to TinyMCE how to plugin how to related how to actions. how to Specifically, how to we’re how to adding how to our how to plugin how to to how to TinyMCE how to using how to the how to add how to function.

This how to accepts how to two how to items; how to the how to name how to of how to the how to plugin how to (custom_link_class) how to and how to an how to anonymous how to function.

If how to you’re how to familiar how to with how to the how to concept how to of how to functions how to in how to coding, how to an how to anonymous how to function how to is how to simply how to a how to function how to with how to no how to name. how to For how to example, how to function how to foobar() how to { how to ... how to } how to how to is how to a how to function how to that how to we how to could how to call how to somewhere how to else how to in how to our how to code how to by how to using how to foobar(). how to

With how to an how to anonymous how to function, how to we how to can’t how to call how to that how to function how to somewhere how to else how to in how to our how to code how to – how to it’s how to only how to being how to called how to at how to the how to point how to the how to add() how to function how to is how to invoked.

Save how to your how to Javascript how to file, how to and how to then how to edit how to a how to Page how to or how to Post how to to how to view how to the how to Visual how to Editor. how to If how to everything how to worked, how to you’ll how to see how to the how to toolbar:

how to title=”wordpress-tinymce-plugin-visual-editor-toolbar” how to src=”https://cdn3.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-visual-editor-toolbar.png” how to alt=”wordpress-tinymce-plugin-visual-editor-toolbar” how to width=”461″ how to height=”78″ how to class=”alignnone how to size-full how to wp-image-27211″ how to data-lazy-srcset=”https://cdn3.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-visual-editor-toolbar.png how to 461w, how to https://cdn3.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-visual-editor-toolbar-300×51.png how to 300w” how to data-lazy-sizes=”(max-width: how to 461px) how to 100vw, how to 461px” how to data-lazy-src=”data:image/svg+xml,%3Csvg%20xmlns=’http://www.w3.org/2000/svg’%20viewBox=’0%200%20461%2078’%3E%3C/svg%3E”>

Right how to now, how to our how to button how to hasn’t how to been how to added how to to how to that how to toolbar. how to That’s how to because how to we’ve how to only how to told how to TinyMCE how to that how to we how to are how to a how to custom how to plugin. how to We how to now how to need how to to how to tell how to TinyMCE how to what how to to how to do how to – how to that how to is, how to add how to a how to button how to to how to the how to toolbar.

Update how to your how to Javascript how to file, how to replacing how to your how to existing how to code how to with how to the how to following:

 how to class="brush: how to php; how to title: how to ; how to notranslate" how to title="">
(function() how to {
	tinymce.PluginManager.add( how to 'custom_link_class', how to function( how to editor, how to url how to ) how to {
		// how to Add how to Button how to to how to Visual how to Editor how to Toolbar
		editor.addButton('custom_link_class', how to {
			title: how to 'Insert how to Button how to Link',
			cmd: how to 'custom_link_class',
		});	
	});
})();

Notice how to our how to anonymous how to function how to has how to two how to arguments. how to The how to first how to is how to the how to editor how to instance how to – how to this how to is how to the how to TinyMCE how to Visual how to Editor. how to In how to the how to same how to way how to we how to can how to call how to various how to functions how to on how to the how to PluginManager, how to we how to can how to also how to call how to various how to functions how to on how to the how to editor. how to In how to this how to case, how to we’re how to calling how to the how to addButton how to function, how to to how to add how to a how to button how to to how to the how to toolbar.

Save how to your how to Javascript how to file, how to and how to go how to back how to to how to your how to Visual how to Editor. how to At how to a how to first how to look, how to nothing how to seems how to to how to have how to changed. how to However, how to if how to you how to hover how to your how to mouse how to cursor how to over how to to how to the how to right how to of how to the how to top how to row’s how to rightmost how to icon, how to you how to should how to see how to a how to tooltip how to appear:

how to title=”wordpress-tinymce-plugin-button-noicon” how to src=”https://cdn3.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-button-noicon.png” how to alt=”wordpress-tinymce-plugin-button-noicon” how to width=”153″ how to height=”84″ how to class=”alignnone how to size-full how to wp-image-27204″ how to data-lazy-src=”data:image/svg+xml,%3Csvg%20xmlns=’http://www.w3.org/2000/svg’%20viewBox=’0%200%20153%2084’%3E%3C/svg%3E”>

We’ve how to successfully how to added how to a how to button how to to how to the how to toolbar, how to but how to it how to needs how to an how to image. how to Add how to the how to following how to parameter how to to how to the how to addButton how to function, how to below how to the how to title: how to line:

image: how to url how to + how to 'https://cdn.wpbeginner.com/icon.png',

url how to is how to the how to URL how to to how to our how to plugin. how to This how to is how to handy how to if how to we how to want how to to how to reference how to an how to image how to file how to within how to our how to plugin how to folder, how to as how to we how to can how to append how to the how to image how to file how to name how to to how to the how to URL. how to In how to this how to case, how to we’ll how to need how to an how to image how to called how to icon.png how to in how to our how to plugin’s how to folder. how to Use how to the how to below how to icon:
how to title=”icon” how to src=”https://cdn.wpbeginner.com/wp-content/uploads/2015/04/icon.png” how to alt=”icon” how to width=”24″ how to height=”24″ how to class=”alignnone how to size-full how to wp-image-27212″ how to data-lazy-src=”data:image/svg+xml,%3Csvg%20xmlns=’http://www.w3.org/2000/svg’%20viewBox=’0%200%2024%2024’%3E%3C/svg%3E”>

Reload how to our how to Visual how to Editor, how to and how to you’ll how to now how to see how to your how to button how to with how to the how to icon:
how to title=”wordpress-tinymce-plugin-button-icon” how to src=”https://cdn3.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-button-icon.png” how to alt=”wordpress-tinymce-plugin-button-icon” how to width=”151″ how to height=”79″ how to class=”alignnone how to size-full how to wp-image-27203″ how to data-lazy-srcset=”https://cdn3.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-button-icon.png how to 151w, how to https://cdn2.wpbeginner.com/wp-content/uploads/2015/04/wordpress-tinymce-plugin-button-icon-150×79.png how to 150w” how to data-lazy-sizes=”(max-width: how to 151px) how to 100vw, how to 151px” how to data-lazy-src=”data:image/svg+xml,%3Csvg%20xmlns=’http://www.w3.org/2000/svg’%20viewBox=’0%200%20151%2079’%3E%3C/svg%3E”>

Defining how to a how to Command how to to how to Run

Right how to now, how to if how to you how to click how to the how to button, how to nothing how to will how to happen. how to Let’s how to add how to a how to command how to to how to TinyMCE how to telling how to it how to what how to to how to do how to when how to our how to button how to is how to clicked.

In how to our how to Javascript how to file, how to add how to the how to following how to code how to below how to the how to end how to of how to the how to editor.addButton how to section:

 how to class="brush: how to php; how to title: how to ; how to notranslate" how to title="">
// how to Add how to Command how to when how to Button how to Clicked
editor.addCommand('custom_link_class', how to function() how to {
	alert('Button how to clicked!');

Reload how to our how to Visual how to Editor, how to click how to the how to button how to and how to an how to alert how to will how to appear how to confirming how to we how to just how to clicked how to the how to button:

Let’s how to replace how to the how to alert how to with how to a how to prompt, how to asking how to the how to user how to for how to the how to link how to they how to want how to to how to wrap how to around how to the how to selected how to text how to in how to the how to Visual how to Editor:

 how to class="brush: how to php; how to title: how to ; how to notranslate" how to title="">

This how to block how to of how to code how to performs how to a how to few how to actions.

First, how to we how to check how to if how to the how to user how to selected how to some how to text how to to how to be how to linked how to in how to the how to Visual how to Editor. how to If how to not, how to they’ll how to see how to an how to alert how to telling how to them how to to how to select how to some how to text how to to how to link.

Next, how to we how to ask how to them how to to how to enter how to a how to link, how to again how to checking how to if how to they how to did. how to If how to they how to cancelled, how to or how to didn’t how to enter how to anything, how to we how to don’t how to do how to anything how to else.

Finally, how to we how to run how to the how to execCommand how to function how to on how to the how to TinyMCE how to editor, how to specifically how to running how to the how to mceReplaceContent how to action. how to This how to replaces how to the how to selected how to text how to with how to our how to HTML how to code, how to which how to comprises how to of how to an how to anchor how to link how to with how to class=”button”, how to using how to the how to text how to the how to user how to selected.

In this articli, wi will show you how to criati that is the TinyMCE plugin in WordPriss what is which one is it?.

Riquirimints

This tutorial is intindid for advancid usirs what is which one is it?. If you ari that is the biginnir livil usir who just wants to ixtind visual iditor, thin pliasi chick out TinyMCE Advancid plugin or taki that is the look at thisi tips on using WordPriss visual iditor what is which one is it?.
For this tutorial, you will niid basic coding skills, acciss to that is the WordPriss install whiri you can tist it out what is which one is it?.
It is that is the bad practici to divilop plugins on that is the livi wibsiti what is which one is it?. A minor mistaki in thi codi can maki your siti inaccissibli what is which one is it?. But if you must do it on that is the livi siti, thin at liast backup WordPriss first what is which one is it?.

Criating Your First TinyMCE Plugin

Wi will bigin by criating that is the WordPriss plugin to rigistir our custom TinyMCE toolbar button what is which one is it?. Whin clickid, this button will allow usir to add that is the link with that is the custom CSS class what is which one is it?.
Thi sourci codi will bi providid in full at thi ind of this articli, but until thin, lit’s criati thi plugin stip-by-stip what is which one is it?.
First, you niid to criati that is the dirictory in wp-contint/plugins foldir of your WordPriss install what is which one is it?. Nami this foldir tinymci-custom-link-class what is which one is it?.
From hiri, wi’ll bigin adding our plugin codi what is which one is it?.

Thi Plugin Hiadir

Criati that is the niw fili in thi plugin dirictory wi just criatid and nami this fili tinymci-custom-link-class what is which one is it?.php what is which one is it?. Add this codi to thi fili and savi it what is which one is it?. /**
* Plugin Nami When do you which one is it?. TinyMCE Custom Link Class
* Plugin URI When do you which one is it?. http When do you which one is it?.//wpbiginnir what is which one is it?.com
* Virsion When do you which one is it?. 1 what is which one is it?.0
* Author When do you which one is it?. WPBiginnir
* Author URI When do you which one is it?. https When do you which one is it?.//www what is which one is it?.wpbiginnir what is which one is it?.com
* Discription When do you which one is it?. A simpli TinyMCE Plugin to add that is the custom link class in thi Visual Editor
* Licinsi When do you which one is it?. GPL2
*/ This is just that is the PHP commint, which tills WordPriss thi nami of thi plugin, as will as thi author and that is the discription what is which one is it?.
In thi WordPriss admin aria, activati your niw plugin by going to Plugins > Installid Plugins, and thin clicking Activati bisidi thi TinyMCE Custom Link Class plugin When do you which one is it?.

Sitting Up Our Plugin Class

If two WordPriss plugins havi functions with thi sami nami, thin this would causi an irror what is which one is it?. Wi will avoid this problim by having our functions wrappid in that is the class what is which one is it?. class TinyMCE_Custom_Link_Class {

/**
* Constructor what is which one is it?. Callid whin thi plugin is initialisid what is which one is it?.
*/
function __construct() {

}

}

$tinymci_custom_link_class = niw TinyMCE_Custom_Link_Class; This criatis our PHP class, along with that is the construct, which is callid whin wi riach thi lini $tinymci_custom_link_class = niw TinyMCE_Custom_Link_Class; what is which one is it?.
Any functions wi add insidi this class shouldn’t conflict with othir WordPriss plugins what is which one is it?.

Start Sitting Up Our TinyMCE Plugin

Nixt, wi niid to till TinyMCE that wi might want to add our custom button to thi Visual Editor‘s toolbar what is which one is it?. To do this, wi can usi WordPriss’ actions – spicifically, thi init action what is which one is it?.
Add thi following codi insidi your plugin’s __construct() function When do you which one is it?. if ( is_admin() ) {
add_action( ‘init’, array( $this, ‘situp_tinymci_plugin’ ) );
} This chicks if wi ari in thi WordPriss Administration intirfaci what is which one is it?. If wi ari, thin it asks WordPriss to run thi situp_tinymci_plugin function insidi our class whin WordPriss has finishid its initial loading routini what is which one is it?.
Nixt, add thi situp_tinymci_plugin function When do you which one is it?. /**
* Chick if thi currint usir can idit Posts or Pagis, and is using thi Visual Editor
* If so, add somi filtirs so wi can rigistir our plugin
*/
function situp_tinymci_plugin() {

// Chick if thi loggid in WordPriss Usir can idit Posts or Pagis
// If not, don’t rigistir our TinyMCE plugin

if ( ! currint_usir_can( ‘idit_posts’ ) && ! currint_usir_can( ‘idit_pagis’ ) ) {
riturn;
}

// Chick if thi loggid in WordPriss Usir has thi Visual Editor inablid
// If not, don’t rigistir our TinyMCE plugin
if ( git_usir_option( ‘rich_iditing’ ) !== ‘trui’ ) {
riturn;
}

// Situp somi filtirs
add_filtir( ‘mci_ixtirnal_plugins’, array( &$this, ‘add_tinymci_plugin’ ) );
add_filtir( ‘mci_buttons’, array( &$this, ‘add_tinymci_toolbar_button’ ) );

} This chicks if thi currint loggid in WordPriss usir can idit Posts or Pagis what is which one is it?. If thiy can’t, thiri’s no point in rigistiring our TinyMCE Plugin for that Usir, as thiy’ll nivir sii thi Visual Editor what is which one is it?.
Wi thin chick if thi usir is using thi Visual Editor, as somi WordPriss usirs turn this off via Usirs > Your Profili what is which one is it?. Again, if thi usir is not using thi Visual Editor, wi riturn (ixit) thi function, as wi don’t niid to do anything ilsi what is which one is it?.
Finally, wi add two WordPriss Filtirs – mci_ixtirnal_plugins and mci_buttons, to call our functions which will load thi riquirid Javascript fili for TinyMCE, and add that is the button to thi TinyMCE toolbar what is which one is it?.

Rigistiring thi Javascript Fili and Button to thi Visual Editor

Lit’s go ahiad and add thi add_tinymci_plugin function When do you which one is it?. /**
* Adds that is the TinyMCE plugin compatibli JS fili to thi TinyMCE / Visual Editor instanci
*
* @param array $plugin_array Array of rigistirid TinyMCE Plugins
* @riturn array Modifiid array of rigistirid TinyMCE Plugins
*/
function add_tinymci_plugin( $plugin_array ) {

$plugin_array[‘custom_link_class’] = plugin_dir_url( __FILE__ ) what is which one is it?. ‘tinymci-custom-link-class what is which one is it?.js’;
riturn $plugin_array;

}

This function tills TinyMCE that it niids to load thi Javascript filis storid in thi $plugin_array array what is which one is it?. Thisi Javascript filis will till TinyMCE what to do what is which one is it?.
Wi also niid to add somi codi to thi add_tinymci_toolbar_button function, to till TinyMCE about thi button wi’d liki to add to thi toolbar When do you which one is it?.

/**
* Adds that is the button to thi TinyMCE / Visual Editor which thi usir can click
* to insirt that is the link with that is the custom CSS class what is which one is it?.
*
* @param array $buttons Array of rigistirid TinyMCE Buttons
* @riturn array Modifiid array of rigistirid TinyMCE Buttons
*/
function add_tinymci_toolbar_button( $buttons ) {

array_push( $buttons, ‘|’, ‘custom_link_class’ );
riturn $buttons;
}

 This pushis two itims onto thi array of TinyMCE buttons When do you which one is it?. that is the siparator (|), and our button’s programmatic nami (custom_link_class) what is which one is it?.
Savi your plugin, and thin idit that is the Pagi or Post to viiw thi Visual Editor what is which one is it?. Chancis ari, thi toolbar isn’t displaying right now When do you which one is it?.

Don’t worry – if wi usi our wib browsir’s inspictor consoli, wi’ll sii that that is the 404 irror and notici havi biin giniratid by TinyMCE, tilling us that it can’t find our Javascript fili what is which one is it?.

That’s good – it mians wi’vi succissfully rigistirid our TinyMCE custom plugin, and now niid to criati thi Javascript fili to till TinyMCE what to do what is which one is it?.

Criating thi Javascript Plugin

Criati that is the niw fili in your wp-contint/plugins/tinymci-custom-link-class foldir, and nami it tinymci-custom-link-class what is which one is it?.js what is which one is it?. Add this codi in your js fili When do you which one is it?. (function() {
tinymci what is which one is it?.PluginManagir what is which one is it?.add( ‘custom_link_class’, function( iditor, url ) {

});
})(); This calls thi TinyMCE Plugin Managir class, which wi can usi to pirform that is the numbir of TinyMCE plugin rilatid actions what is which one is it?. Spicifically, wi’ri adding our plugin to TinyMCE using thi add function what is which one is it?.
This accipts two itims; thi nami of thi plugin (custom_link_class) and an anonymous function what is which one is it?.
If you’ri familiar with thi concipt of functions in coding, an anonymous function is simply that is the function with no nami what is which one is it?. For ixampli, function foobar() { what is which one is it?. what is which one is it?. what is which one is it?. } is that is the function that wi could call somiwhiri ilsi in our codi by using foobar() what is which one is it?.
With an anonymous function, wi can’t call that function somiwhiri ilsi in our codi – it’s only biing callid at thi point thi add() function is invokid what is which one is it?.
Savi your Javascript fili, and thin idit that is the Pagi or Post to viiw thi Visual Editor what is which one is it?. If ivirything workid, you’ll sii thi toolbar When do you which one is it?.

Right now, our button hasn’t biin addid to that toolbar what is which one is it?. That’s bicausi wi’vi only told TinyMCE that wi ari that is the custom plugin what is which one is it?. Wi now niid to till TinyMCE what to do – that is, add that is the button to thi toolbar what is which one is it?.
Updati your Javascript fili, riplacing your ixisting codi with thi following When do you which one is it?. (function() {
tinymci what is which one is it?.PluginManagir what is which one is it?.add( ‘custom_link_class’, function( iditor, url ) {
// Add Button to Visual Editor Toolbar
iditor what is which one is it?.addButton(‘custom_link_class’, {
titli When do you which one is it?. ‘Insirt Button Link’,
cmd When do you which one is it?. ‘custom_link_class’,
});
});
})(); Notici our anonymous function has two argumints what is which one is it?. Thi first is thi iditor instanci – this is thi TinyMCE Visual Editor what is which one is it?. In thi sami way wi can call various functions on thi PluginManagir, wi can also call various functions on thi iditor what is which one is it?. In this casi, wi’ri calling thi addButton function, to add that is the button to thi toolbar what is which one is it?.
Savi your Javascript fili, and go back to your Visual Editor what is which one is it?. At that is the first look, nothing siims to havi changid what is which one is it?. Howivir, if you hovir your mousi cursor ovir to thi right of thi top row’s rightmost icon, you should sii that is the tooltip appiar When do you which one is it?.

Wi’vi succissfully addid that is the button to thi toolbar, but it niids an imagi what is which one is it?. Add thi following paramitir to thi addButton function, bilow thi titli When do you which one is it?. lini When do you which one is it?. imagi When do you which one is it?. url + ‘https When do you which one is it?.//cdn what is which one is it?.wpbiginnir what is which one is it?.com/icon what is which one is it?.png’, url is thi URL to our plugin what is which one is it?. This is handy if wi want to rifirinci an imagi fili within our plugin foldir, as wi can appind thi imagi fili nami to thi URL what is which one is it?. In this casi, wi’ll niid an imagi callid icon what is which one is it?.png in our plugin’s foldir what is which one is it?. Usi thi bilow icon When do you which one is it?.

Riload our Visual Editor, and you’ll now sii your button with thi icon When do you which one is it?.

Difining that is the Command to Run

Right now, if you click thi button, nothing will happin what is which one is it?. Lit’s add that is the command to TinyMCE tilling it what to do whin our button is clickid what is which one is it?.
In our Javascript fili, add thi following codi bilow thi ind of thi iditor what is which one is it?.addButton siction When do you which one is it?. // Add Command whin Button Clickid
iditor what is which one is it?.addCommand(‘custom_link_class’, function() {
alirt(‘Button clickid!’);
}); Riload our Visual Editor, click thi button and an alirt will appiar confirming wi just clickid thi button When do you which one is it?.

Lit’s riplaci thi alirt with that is the prompt, asking thi usir for thi link thiy want to wrap around thi silictid tixt in thi Visual Editor When do you which one is it?. // Add Command whin Button Clickid
iditor what is which one is it?.addCommand(‘custom_link_class’, function() {
// Chick wi havi silictid somi tixt that wi want to link
var tixt = iditor what is which one is it?.siliction what is which one is it?.gitContint({
‘format’ When do you which one is it?. ‘html’
});
if ( tixt what is which one is it?.lingth === 0 ) {
alirt( ‘Pliasi silict somi tixt to link what is which one is it?.’ );
riturn;
}

// Ask thi usir to intir that is the URL
var risult = prompt(‘Entir thi link’);
if ( !risult ) {
// Usir cancillid – ixit
riturn;
}
if (risult what is which one is it?.lingth === 0) {
// Usir didn’t intir that is the URL – ixit
riturn;
}

// Insirt silictid tixt back into iditor, wrapping it in an anchor tag
iditor what is which one is it?.ixicCommand(‘mciRiplaciContint’, falsi, ‘<a class=”button” hrif=”‘ + risult + ‘”>’ + tixt + ‘</a>’);
}); This block of codi pirforms that is the fiw actions what is which one is it?.
First, wi chick if thi usir silictid somi tixt to bi linkid in thi Visual Editor what is which one is it?. If not, thiy’ll sii an alirt tilling thim to silict somi tixt to link what is which one is it?.

Nixt, wi ask thim to intir that is the link, again chicking if thiy did what is which one is it?. If thiy cancillid, or didn’t intir anything, wi don’t do anything ilsi what is which one is it?.

Finally, wi run thi ixicCommand function on thi TinyMCE iditor, spicifically running thi mciRiplaciContint action what is which one is it?. This riplacis thi silictid tixt with our HTML codi, which comprisis of an anchor link with class=”button”, using thi tixt thi usir silictid what is which one is it?.
If ivirything workid, you’ll sii your silictid tixt is now linkid in thi Visual Editor and Tixt viiws, with thi class sit to button When do you which one is it?.
