Custom fields are a handy WordPress feature that allows you to add various additional data / information to your WordPress posts and pages.

A lot of popular WordPress plugins and themes use custom fields to store important data. You can also use custom fields to store your own data and then use it on your website.

In this article, we’ll show you how to use WordPress custom fields with some tips, tricks, and hacks.

What are WordPress Custom Fields?

WordPress custom fields are metadata used to add additional information related to the post or page you are editing.

By default, WordPress saves it into two different areas when you write a new post, page, or any content type.

The first part is the body of your content that you add using the post editor.

The second part is the information about that particular content. For example, title, author, date, time, and more. This information bit of the post is called metadata.

WordPress automatically adds all the required metadata to each post or page you create.

You can also create and store your own metadata by using the custom fields.

By default, the custom fields option is hidden on the post edit screen. To view it, you need to click on the three-dot menu at the top-right corner of the screen and select ‘Options’ from the menu.

Post editor options

This will bring up a popup where you need to check the ‘Custom fields’ option under the Advanced Panels. After that, click on the ‘Enable & Reload’ button to reload the post editor.

Enable and display custom fields panel

The post editor will reload, and you’ll be able to see the custom fields panel below the content editor.

Custom fields metabox below the post editor

Custom fields can be used to add any information related to the post, page, or any content type. This meta-information can be displayed in your theme.

However, to do that you will need to edit your WordPress theme files.

This is why this tutorial is recommended for users familiar with editing theme files. It is also helpful for aspiring WordPress developers who want to learn how to properly use custom fields in their own themes or plugins.

Having said that, let’s take a look at how to add and use custom fields in WordPress.

Adding Custom Fields in WordPress

First, you need to edit the post or page where you want to add the custom field and go to the custom fields meta box.

Adding custom field name and value

Next, you need to provide a name for your custom field and then enter its value. Click on the Add Custom Field button to save it.

The field will be stored and displayed in the custom fields meta box like this:

Saved custom field

You can edit this custom field any time you want and then click on the update button to save your changes. You can also delete it as needed.

Now you can save your post to store your custom field settings.

Displaying Custom Fields in WordPress Themes

To display your custom field on your website, you will need to edit your WordPress theme files. If you haven’t done this before, then take a look at our guide on how to copy and paste code in WordPress.

First, you will need to find the theme file that you need to edit to display your custom field. Ideally, you would want to display it on a single post page. You will need to edit the single.php or content-single.php file.

You will need to enter your custom fields code inside the WordPress loop. Look for the line that looks like this:

<?php while ( have_posts() ) : the_post(); ?>

You want to make sure that you add your code before the following line:

<?php endwhile; // end of the loop. ?>

Now you need to add this code to your theme file:

<?php echo get_post_meta($post->ID, 'key', true); ?>

Don’t forget to replace the key with the name of your custom field. For example, we used this code in our demo theme:

<p>Today's Mood: <?php echo get_post_meta($post->ID, 'Mood', true); ?></p>

You can now save your changes and visit the post where you added the custom field to see it in action.

Custom field data displayed in a WordPress theme

Now you can use this custom field in all your other WordPress posts as well.

Simply create a new post or edit an existing one. Go to the custom fields meta box and select your custom field from the drop-down menu and enter its value.

Reuse custom field

Click on the ‘Add Custom Field’ button to save your changes and then publish or update your post.

Can’t Find Custom Field in Dropdown on Post Edit Screen

By default, WordPress only loads 30 custom fields in this form.

If you are using WordPress themes and plugins that already use custom fields, then there is a chance that those will appear first in the drop-down menu and you’ll not be able to see your newly created custom field.

To fix this issue, you’ll need to add the following code to your theme’s functions.php file or a site-specific plugin.


add_filter( 'postmeta_form_limit', 'meta_limit_increase' );
function meta_limit_increase( $limit ) {
    return 50;
}

The above code will change that limit to 50. If you still can’t see your custom field then try increasing that limit even further.

Creating a User Interface for Custom Fields

As you can see, that once you add a custom field, you will have to select the field and enter its value each time you write a post.

If you have many WordPress custom fields or multiple users writing on your website, then this is not an ideal solution.

Wouldn’t it be nice if you could create a user interface where users can fill in a form to add values to your custom fields?

This is what so many popular WordPress plugins already do. For example, the SEO title and meta description box inside the popular All in One SEO plugin is a custom meta box:

All in One SEO Pack Meta Box

The easiest way to do this is by using the Advanced Custom Fields plugin.

Adding Custom Fields Using Advanced Custom Fields

First thing you need to do is install and activate the Advanced Custom Fields plugin. For more details, see our step by step guide on how to install a WordPress plugin.

Upon activation, you need to visit Custom Fields » Field Groups page and click on the add new button.

Add new field group

A field group is like a container of a set of custom fields. This allows you to add multiple panels of custom fields.

Now, you need to provide a title for your field group and then click on the ‘Add Field’ button.

Add new field

You can now provide a name for your custom field and select a field type. Advanced Custom Fields allows you to create all sorts of fields including text, image upload, number, dropdown, checkboxes, and more.

Adding a new fielld

Scroll down, and you’ll see other options for that particular field. You can change them to your own requirements.

You can add multiple fields to your field group if you want. Once you are finished, click on the publish button to save your changes.

You can now edit a post or create a new one and you’ll see a new panel for your WordPress custom fields below the content editor.

Custom field panel on the post edit screen

For detailed step by step instructions, see our guide on how to add custom meta boxes in WordPress posts and post types.

Hide Empty Custom Fields with Conditional Statement

So far we have covered how to create a custom field and display it in your theme.

Now let’s see how to check if the custom field is not empty before displaying it. To do that, we will modify our code to first check if the field has data in it.

<?php 

$mood = get_post_meta($post->ID, 'Mood', true);

if ($mood) { ?>

<p>Today's Mood: <? echo $mood; ?></p>

<?php 

} else { 
// do nothing; 
}

?>

Don’t forget to replace Mood with your own custom field name.

Adding Multiple Values to a Custom Field

Custom fields can be reused in the same post again to add multiple values. You just need to select it again and add another value.

Adding multiple values to a custom field

However, the code we have used in the above examples will only be able to show a single value.

To display all values of a custom field, we need to modify the code and make it return the data in an array. You will need to add the following code in your theme file:

<?php 
$mood = get_post_meta($post->ID, 'Mood', false);
if( count( $mood ) != 0 ) { ?>
<p>Today's Mood:</p>
<ul>
<?php foreach($mood as $mood) {
            echo '<li>'.$mood.'</li>';
            }
            ?>
</ul>
<?php 
} else { 
// do nothing; 
}
?>

Don’t forget to replace Mood with your own custom field name.

In this example, you would notice that we have changed the last parameter of get_post_meta function to false. This parameter defines whether the function should return a single value or not. Setting it to false allows it to return the data as an array, which we then displayed in a foreach loop.

Search Post by Custom Field in WordPress

WordPress’s default search doesn’t work with any custom field you have on your website. It only uses the content to find the post you are looking for on your site.

However, SearchWP changes that and improves your WordPress search. It’s the best WordPress search plugins and it goes beyond using just the post content and indexes everything, including WordPress custom fields, PDF documents, custom tables, text, files, and more.

You can adjust the search algorithm without editing code using SearchWP. Simply install the plugin and then head over to Settings » SearchWP from your WordPress admin area.

After that, go to the ‘Engines’ tab and then adjust the Attribute Relevance slider to set the weights givens to each attribute during search.

SearchWP engines example

For instance, you configure the Custom Fields slider to maximum and adjust sliders for other attributes accordingly. This way, SearchWP will give preference to data in custom fields when searching things in WordPress.

Another advantage of using SearchWP is that works with some of the most popular custom field plugins like Advanced Custom Fields (ACF), Meta Box, and Pods.

For more details, you can go through our guide on how to improve WordPress search with SearchWP.

Displaying Posts with a Specific Custom Key

WordPress allows you to display posts with custom keys and their values. For example, if you are trying to create a custom archive page to display all posts with specific custom keys, then you can use WP_Query class to query posts matching those fields.

You can use the following code as a starting point.

$args = array(
	'meta_key'   => 'Mood',
	'meta_value' => 'Happy'
);
$the_query = new WP_Query( $args );

<?php 
// the query
$the_query = new WP_Query( $args ); ?>

<?php if ( $the_query->have_posts() ) : ?>

	<!-- the loop -->
	<?php while ( $the_query->have_posts() ) : $the_query->the_post(); ?>
		<h2><?php the_title(); ?></h2>
		<?php the_content(); ?>

	<?php endwhile; ?>
	<!-- end of the loop -->

	<!-- pagination here -->

	<?php wp_reset_postdata(); ?>

<?php else : ?>
	<p><?php _e( 'Sorry, no posts matched your criteria.' ); ?></p>
<?php endif; ?>

Don’t forget to replace meta_key and meta_value parameters with your own values.

Add Guest Author Name Using Custom Fields

Do you want to add a guest post but don’t want to add a new user profile just to add a single post? An easier way to do that is by adding a guest author name as a custom field.

First, you need to add the following code in your theme’s functions.php file or a site-specific plugin.

add_filter( 'the_author', 'guest_author_name' );
add_filter( 'get_the_author_display_name', 'guest_author_name' );
function guest_author_name( $name ) {
global $post;
$author = get_post_meta( $post->ID, 'guest-author', true );
if ( $author )
$name = $author;
return $name;
}

This code hooks a function to the_author and get_the_author_display_name filters in WordPress.

The function first checks for the guest author’s name. If it exists, then it replaces the author’s name with the guest author’s name.

Now you will need to edit the post where you want to display the guest author name. Go to the custom fields meta box and add your guest author name.

Adding guest author custom field

For details, see our article on how to rewrite guest author name with custom fields in WordPress.

Display Contributors to an Article Using Custom Fields

On many popular blogs and news sites, multiple authors contribute to write an article. However, WordPress only allows a single author to be associated with a post.

One way to solve this problem is by using Co-Authors Plus plugin. To learn more, see our guide on how to add multiple authors on a WordPress post.

Another way to do that is by adding contributors as a custom field.

First, you need to edit the post where you want to display co-authors or contributors. Scroll down to the custom fields meta box and add author names as co-author custom field.

Adding co-author custom field

Now add this code to your theme files where you want to show co-authors.


<?php 

$coauthors = get_post_meta($post->ID, 'co-author', false);
if( count( $coauthors ) != 0 ) { ?>
<ul class="coauthors">
<li>Contributors</li>
<?php foreach($coauthors as $coauthors) { ?>
           <?php echo '<li>'.$coauthors.'</li>' ;
            }
            ?>
</ul>
<?php 
} else { 
// do nothing; 
}
?>

To display author names separated by commas, you can add the following custom CSS.

.coauthors ul { 
display:inline;
}
.coauthors li { 
display:inline;
list-style:none;
}
.coauthors li:after { 
content:","
}
.coauthors li:last-child:after {
    content: "";
}
.coauthors li:first-child:after {
    content: ":";
}

This is how it looked on our demo site.

Co-authors displayed using custom fields

Display Custom Fields Outside the Loop in WordPress

So far we have shown you all the examples where custom fields are displayed inside the WordPress loop. What if you needed to show them outside the loop? For example, in the sidebar of a single post.

To display the custom fields outside the WordPress loop add the following code:

<?php
global $wp_query;
$postid = $wp_query->post->ID;
echo get_post_meta($postid, 'key', true);
wp_reset_query();
?>

Don’t forget to replace the key with your custom field name.

Display Custom Header, Footer, Sidebar using Custom Fields

Usually, most WordPress themes use the same header, footer, and sidebar on all pages. There are multiple ways to show different sidebars, header, or footer for different pages on your website. See our guide on how to display different sidebar for each WordPress post or page.

One way to do this is by using custom fields. Edit the post or page where you want to show a different sidebar and then add the sidebar as a custom field.

Adding custom sidebar to a post using custom field

Now you need to edit your WordPress theme files like single.php where you want to display custom sidebar. You will be looking for the following code:

<?php get_sidebar(); ?>

Replace this line with the following code:

<?php 
global $wp_query;
$postid = $wp_query->post->ID;
$sidebar = get_post_meta($postid, "sidebar", true);
get_sidebar($sidebar);
wp_reset_query();
?>

This code simply looks for the sidebar custom field and then displays it in your theme. For example, if you add wpbpage as your sidebar custom field, then the code will look for a sidebar-wpbpage.php file to display.

You will need to create the sidebar-wpbpage.php file in your theme folder. You can copy the code from your theme’s sidebar.php file as a starting point.

Manipulating RSS feed Content with Custom Fields

Want to display additional metadata or content to your RSS feed users? Using custom fields you can manipulate your WordPress RSS feed and add custom content into your feeds.

First you need to add the following code in your theme’s functions.php file or a site-specific plugin.

function wpbeginner_postrss($content) {
global $wp_query;
$postid = $wp_query->post->ID;
$coolcustom = get_post_meta($postid, 'coolcustom', true);
if(is_feed()) {
if($coolcustom !== '') {
$content = $content."<br /><br /><div>".$coolcustom."</div>
";
}
else {
$content = $content;
}
}
return $content;
}
add_filter('the_excerpt_rss', 'wpbeginner_postrss');
add_filter('the_content', 'wpbeginner_postrss');

Now just create a custom field called “coolcustom” and add any value you like. You can use it to display advertisements, images, text, or anything you want.

Manipulate RSS Feed Title with Custom Fields

Sometimes you may want to add extra text to a post title for RSS feed users. For example, if you are publishing a sponsored post or a guest post.

First you add the following code in your theme’s functions.php file or a site-specific plugin.

function wpbeginner_titlerss($content) {
global $wp_query;
$postid = $wp_query->post->ID;
$gpost = get_post_meta($postid, 'guest_post', true);
$spost = get_post_meta($postid, 'sponsored_post', true);

if($gpost !== '') {
$content = 'Guest Post: '.$content;
}
elseif ($spost !== ''){
$content = 'Sponsored Post: '.$content;
}
else {
$content = $content;
}
return $content;
}
add_filter('the_title_rss', 'wpbeginner_titlerss');

Next, you need to edit the post where you want to display the extra text in the title field and add guest_post and sponsored_post in custom fields.

Set Expiration Date for Posts in WordPress Using Custom Fields

Want to set an expiration date for some posts on your WordPress site? This comes in handy in situations when you want to publish content only for a specific period like running surveys or limited-time offers.

One way to do this is by manually removing the post content or by using a plugin like Post Expirator plugin.

Another way to do this is by using custom fields to automatically expire posts after a specific time.

You will need to edit your theme files and add modify the WordPress loop like this:

<?php
if (have_posts()) :
while (have_posts()) : the_post(); 
$expirationtime = get_post_meta($post->ID, "expiration", false);
if( count( $expirationtime ) != '' ) { 
if (is_array($expirationtime)) {
$expirestring = implode($expirationtime);
}

$secondsbetween = strtotime($expirestring)-time();
if ( $secondsbetween >= 0 ) {
echo 'This post will expire on ' .$expirestring.'';
the_content();
} else { 
echo "Sorry this post expired!"
}
} else { 
the_content();
} 
endwhile;
endif;
?>

Note: You will need to edit this code to match your theme.

After adding this code, you can add the expiration custom field to the post you want to expire. Make sure you add the time in this format mm/dd/yyyy 00:00:00.

Adding an expiration date using custom field

Style Individual Posts Using Custom Fields

Want to change the look of an individual post using CSS? WordPress automatically assigns each post its own class which you can use to add custom CSS.

However, using custom fields you can add your own custom classes and then use them to style posts differently.

First, you need to edit a post that you would like to style differently. Go to the custom fields box and the post-class custom field.

Post class custom field

Next, you need to edit your WordPress theme files and add this code at the beginning of the WordPress loop.

<?php $custom_values = get_post_meta($post->ID, 'post-class'); ?>

Now you need to find a line with the post_class() function. Here is how it looked in our demo theme:

<article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>

Change this line to include your custom field value, like this:

<article id="post-<?php the_ID(); ?>" <?php post_class($custom_values); ?>>

Now if you examine the post’s source code using Inspect tool, then you will see your custom field CSS class added to the post-class.

Custom field post class

Now you can use this CSS class to add custom CSS and style your post differently.

}
?> So, how much?
< So, how much? /ul> So, how much?
