How To Increase Default Number of Fields in Custom Fields Dropdown

Snippets by IsItWP

Are you looking for a way to increase the default number of fields in the custom fields dropdown? While there’s probably a plugin for this, we have created a quick code snippet that you can use to increase the default number of fields in the custom fields dropdown from the default of 30 to 60.

Instructions:

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

Keep in mind the same dropdown is displayed for each custom field metabox you have, so you may want to set the limit to a reasonable number if you decide to change line 3.

add_filter( 'postmeta_form_limit' , 'set_customfield_limit' );
function set_customfield_limit( $limit ) {
    $limit = 60;
    return $limit;
}
