Are you looking for a way to enable a custom field of a specific key? While there’s probably a plugin for this, we have created a quick code snippet that you can use to enable a specific custom field in WordPress.
All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:
<?php echo get_post_meta($post->ID, 'insert name here', true); ?>
You need to replace ‘insert name here’ with your custom field name.
Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly add code snippets in WordPress, so you don’t accidentally break your site.
