The Importance of Using Custom Fields in WordPress Websites
Custom fields are a valuable feature in WordPress that allows users to add additional information and metadata to their posts and pages. They provide a way to store and display extra details like titles, authors, and publish dates. Although the concept of custom fields may seem complicated, there are various methods available in WordPress to achieve this. One popular option is the Advanced Custom Fields (ACF) plugin, which simplifies the process.

Displaying WordPress Posts with Specific Custom Field Values
In this article, we will guide you through the process of displaying WordPress posts that have a specific custom field value. Please note that this tutorial involves making changes to your theme’s files. If you’re not familiar with this process, take a look at our guide on how to copy and paste code in WordPress. It’s also essential to have a basic understanding of WordPress loops, as we’ll be utilizing parameters in a WordPress query.
Let’s get started with the following steps:
Step 1: Insert the Code Snippet
Copy and paste the following code snippet into the custom page template file of your WordPress website, where you want the list of posts with the custom field to be displayed:
<?php
$args = array(
'post_type' => 'post',
'meta_query' => array(
array(
'key' => 'color',
'value' => '',
'compare' => 'EXISTS'
)
)
);
$loop = new WP_Query($args);
?>
<?php if ( $loop->have_posts() ) : ?>
<?php while ( $loop->have_posts() ) : $loop->the_post(); ?>
<div>
<!-- Your post content markup here -->
</div>
<?php endwhile; ?>
<?php endif; ?>
Note: On line 5, replace ‘color’ with the name of your custom field. This code snippet will display posts that have a custom field value of ‘color,’ regardless of the specific color value.
Step 2: Customize the Query
If you want to showcase posts with a custom field that has a specific value, modify the query like this:
'key' => 'field_name',
'value' => 'specific_value',
This will display all posts that have a custom field value of ‘specific_value’ in any field.
To ensure that only the ‘color’ field has a value of ‘blue,’ use the following code:
'key' => 'color',
'value' => 'blue',
For more information on additional query parameters, refer to the WordPress WP_Query code reference page.
Step 3: Preview the Changes
Save the code in your page template PHP file and visit the frontend of your WordPress site to see the custom field filter in action. You should now be able to view the posts that meet your specific custom field value criteria.
