Do you want to create your own custom widgets in WordPress? Widgets allow you to add non-content elements into a sidebar or any widget-ready area of your website.
You can use widgets to add banners, advertisements, newsletter sign up forms, and other elements to your website.
In this article, we will show you how to create a custom WordPress widget, step by step.
Note: This tutorial is for DIY WordPress users who are learning WordPress development and coding.
What is a WordPress Widget?
WordPress widgets contain pieces of code that you can add to your website’s sidebars or widget-ready areas.
Think of them as modules that you can use to add different elements and features to your site.
By default, WordPress comes with a standard set of widgets that you can use with any WordPress theme. For more details, see our beginner’s guide on how to add and use widgets in WordPress.
WordPress also allows developers to create their own custom widgets.
Many premium WordPress themes and plugins come with their own custom widgets that you can add to your sidebars.
For example, you can add a contact form, a custom login form, a photo gallery, an email list sign up form, and more, to a sidebar without writing any code.
Having said that, let’s see how you can easily create your own custom widgets in WordPress.
Before You Create a Custom Widget in WordPress
If you are learning WordPress coding, then you will need a local development environment. This gives you the freedom to learn and test things without the worry of your site being live.
You can install WordPress locally on Mac using MAMP or Windows using WAMP.
If you already have a live site, then you can move it to a local host. For more details, see our guide on how to move a live WordPress site to a local server.
After that, there are several ways to add your custom widget code in WordPress.
Ideally, you can create a site-specific plugin and paste your widget code there. This lets you add code to WordPress that isn’t dependent on your WordPress theme.
You can also paste the code in your theme’s functions.php file. However, it will only be available when that particular theme is active.
Another tool that you can use is the Code Snippets plugin which allows you to easily add custom code to your WordPress website.
In this tutorial, we’ll create a simple widget that just greets visitors. The goal here is to familiarize yourself with the WordPress widget class.
Ready? Let’s get started.
Creating a Basic WordPress Widget
WordPress comes with a built-in WordPress Widget class. Each new WordPress widget extends the WordPress widget class.
There are 18 methods mentioned in the WordPress developer’s handbook that can be used with the WP Widget class.
However, for the sake of this tutorial, we will be focusing on the following methods.
- __construct() : This is the part where we create the widget ID, title, and description.
- widget : This is where we define the output generated by the widget.
- form : This part of the code is where we create the form with widget options for backend.
- update: This is the part where we save widget options in the database.
Let’s study the following code where we have used these four methods inside the WP_Widget class.
// Creating the widget
class wpb_widget extends WP_Widget {
// The construct part
function __construct() {
}
// Creating widget front-end
public function widget( $args, $instance ) {
}
// Creating widget Backend
public function form( $instance ) {
}
// Updating widget replacing old instances with new
public function update( $new_instance, $old_instance ) {
}
// Class wpb_widget ends here
}
The final piece of the code is where we will actually register the widget and load it inside WordPress.
function wpb_load_widget() {
register_widget( 'wpb_widget' );
}
add_action( 'widgets_init', 'wpb_load_widget' );
Now let’s put all of this together to create a basic WordPress widget.
You can copy and paste the following code snippet to your functions.php file, in a site-specific plugin, or by using a code snippets plugin.
// Creating the widget
class wpb_widget extends WP_Widget {
function __construct() {
parent::__construct(
// Base ID of your widget
'wpb_widget',
// Widget name will appear in UI
__('WPBeginner Widget', 'wpb_widget_domain'),
// Widget description
array( 'description' => __( 'Sample widget based on WPBeginner Tutorial', 'wpb_widget_domain' ), )
);
}
// Creating widget front-end
public function widget( $args, $instance ) {
$title = apply_filters( 'widget_title', $instance['title'] );
// before and after widget arguments are defined by themes
echo $args['before_widget'];
if ( ! empty( $title ) )
echo $args['before_title'] . $title . $args['after_title'];
// This is where you run the code and display the output
echo __( 'Hello, World!', 'wpb_widget_domain' );
echo $args['after_widget'];
}
// Widget Backend
public function form( $instance ) {
if ( isset( $instance[ 'title' ] ) ) {
$title = $instance[ 'title' ];
}
else {
$title = __( 'New title', 'wpb_widget_domain' );
}
// Widget admin form
?>
<p>
<label for="<?php echo $this->get_field_id( 'title' ); ?>"><?php _e( 'Title:' ); ?></label>
<input class="widefat" id="<?php echo $this->get_field_id( 'title' ); ?>" name="<?php echo $this->get_field_name( 'title' ); ?>" type="text" value="<?php echo esc_attr( $title ); ?>" />
</p>
<?php
}
// Updating widget replacing old instances with new
public function update( $new_instance, $old_instance ) {
$instance = array();
$instance['title'] = ( ! empty( $new_instance['title'] ) ) ? strip_tags( $new_instance['title'] ) : '';
return $instance;
}
// Class wpb_widget ends here
}
// Register and load the widget
function wpb_load_widget() {
register_widget( 'wpb_widget' );
}
add_action( 'widgets_init', 'wpb_load_widget' );
After adding the code to WordPress, you need to head over to the Appearance » Widgets page in your WordPress admin panel.
Then, click the ‘Plus’ add block icon and search for ‘WPBeginner Widget’ and select the new widget.
This widget has only one form field to fill in.
You can add your text and click on the ‘Update’ button to store your changes.
Now, you can visit your WordPress website to see the custom widget in action.
Adding Custom Widget in WordPress Classic Editor
If you’re using the classic widget editor to add new widgets to your site, then the process will be similar.
There will be a new widget called ‘WPBeginner Widget’ in the list of available widgets. You need to drag and drop this widget into your sidebar.
Then, enter a title and click ‘Save’ to save your widget settings.
Your new custom widget will now be live on your website.
Now, let’s study the code again.
First we registered the ‘wpb_widget’ and loaded our custom widget. After that we defined what that widget does, and how to display the widget back-end.
Lastly, we defined how to handle changes made to the widget.
Now there are a few things that you might want to ask. For example, what’s the purpose of wpb_text_domain?
WordPress uses ‘gettext’ to handle translation and localization. This wpb_text_domain and __e tells ‘gettext’ to make a string available for translation. To learn more, see our guide on how you can find translation ready WordPress themes.
If you are creating a custom widget for your theme, then you can replace wpb_text_domain with your theme’s text domain.
Alternatively, you can use a WordPress translation plugin to translate WordPress easily and create a multilingual WordPress site.

In how to this how to tutorial, how to we’ll how to create how to a how to simple how to widget how to that how to just how to greets how to visitors. how to The how to goal how to here how to is how to to how to familiarize how to yourself how to with how to the how to WordPress how to widget how to class.
Ready? how to Let’s how to get how to started.
Creating how to a how to Basic how to WordPress how to Widget
WordPress how to comes how to with how to a how to built-in how to WordPress how to Widget how to class. how to Each how to new how to WordPress how to widget how to extends how to the how to WordPress how to widget how to class.
There how to are how to 18 how to methods how to mentioned how to in how to the how to WordPress how to developer’s how to handbook how to that how to can how to be how to used how to with how to the how to how to title=”WP_Widget” how to href=”https://developer.wordpress.org/reference/classes/wp_widget/” how to target=”_blank” how to rel=”noopener how to nofollow”>WP how to Widget how to class.
However, how to for how to the how to sake how to of how to this how to tutorial, how to we how to will how to be how to focusing how to on how to the how to following how to methods.
- __construct() how to : how to This how to is how to the how to part how to where how to we how to create how to the how to widget how to ID, how to title, how to and how to description.
- widget how to : how to This how to is how to where how to we how to define how to the how to output how to generated how to by how to the how to widget.
- form how to : how to This how to part how to of how to the how to code how to is how to where how to we how to create how to the how to form how to with how to widget how to options how to for how to backend.
- update: how to This how to is how to the how to part how to where how to we how to save how to widget how to options how to in how to the how to database.
Let’s how to study how to the how to following how to code how to where how to we how to have how to used how to these how to four how to methods how to inside how to the how to WP_Widget how to class.
how to class="brush: how to php; how to title: how to ; how to notranslate" how to title=""> // how to Creating how to the how to widget class how to wpb_widget how to extends how to WP_Widget how to { // how to The how to construct how to part function how to __construct() how to { } // how to Creating how to widget how to front-end public how to function how to widget( how to $args, how to $instance how to ) how to { } // how to Creating how to widget how to Backend public how to function how to form( how to $instance how to ) how to { } // how to Updating how to widget how to replacing how to old how to instances how to with how to new public how to function how to update( how to $new_instance, how to $old_instance how to ) how to { } // how to Class how to wpb_widget how to ends how to here }
The how to final how to piece how to of how to the how to code how to is how to where how to we how to will how to actually how to register how to the how to widget how to and how to load how to it how to inside how to WordPress.
