Why Display WordPress Posts With a Specific Custom Field?

One of our users asked us how to display WordPress posts only if a specific custom field was present. After replying back with the answer, we thought it would be best to share it with everyone else, so the larger community can benefit from it as well.
With that being said, let’s take a look at how to display a WordPress post only if it has a specific custom field.
Displaying a WordPress Post Only if It Has a Specific Custom Field
To follow this guide, you’ll have to add code to your WordPress theme’s files. If you haven’t done this before, then see our guide on how to copy and paste code in WordPress.
You need to have a fair understanding of how WordPress loops work because we will call these parameters in a WordPress query.
You need to paste the following loop code wherever you want to display the list of posts with the custom field. Most likely that will be in a custom WordPress page template.
<?php // The Query to show a specific Custom Field $the_query = new WP_Query('meta_key=color'); // The Loop while ( $the_query->have_posts() ) : $the_query->the_post(); the_title(); the_content(); endwhile; // Reset Post Data wp_reset_postdata(); ?>
This example code only shows posts that have a custom field called ‘color’ regardless of what that color value is. Don’t forget to change ‘color’ on line 5 to the name of your custom field.
Now if you want to show posts that have a custom field with a specific value, then you just have to change the query like this:
$the_query = new WP_Query( 'meta_value=blue' );
This will display all posts that have a ‘blue’ value in any custom field.
If you want to make sure that the ‘color’ field has a ‘blue’ value, then your query code will look like this:
$the_query = new WP_Query( array( 'meta_key' => 'color', 'meta_value' => 'blue' ) );
You can learn about additional parameters you can use in your query on the WordPress WP_Query code reference page.
