Get Custom Fields Globally

Snippets by IsItWP

Do you want to get custom field values globally from themes that use a lot of custom fields? While there’s probably a plugin for this, we have created a quick code snippet that you can use to get custom fields globally in WordPress.

Instructions:

All you have to do is add this code to your theme’s functions.php file or in a site-specific plugin:

function get_custom_field($key, $echo = FALSE) {
    global $post;
    $custom_field = get_post_meta($post->ID, $key, true);
    if ($echo == FALSE) return $custom_field;
    echo $custom_field;
}
<?php 
         get_custom_field('custom-field-name', TRUE); 
?>

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.

    Does one have the ability to specify categories, values and keys?

    1. This snippet will not let you specify the category of the post you retrieve the custom field from. This snippet will however let you specify the custom field key just change “custom-field-name”

      get_custom_field(‘custom-field-name’, TRUE);
