How to use auth_object_type_sub_type_meta_meta_key filter in WordPress

auth_object_type_sub_type_meta_meta_key filter

Just like any good Indian developer, we love making things super easy and clear. Let’s dive into the `auth_object_type_sub_type_meta_meta_key` filter. You’ll find this filter super handy when you need to modify capabilities for specific object types/subtypes. When you return true, the mapped meta caps from `edit_{object_type}` will apply.

To get started with the `auth_object_type_sub_type_meta_meta_key` filter, you’ll first need to register it using `add_filter`. You can place this code in the `functions.php` file of your activated theme or even better, in a custom WordPress Plugin. Here at WePlugins, we always prefer creating custom plugins to avoid any issues during theme updates.

Here’s a breakdown of how to use this hook:

Parameters

Below are the 6 parameters required to use this hook:

• $allowed : (bool) Whether the user can add the post meta. Default false.
• $meta_key : (string) The meta key.
• $post_id : (int) Post ID.
• $user_id : (int) User ID.
• $cap : (string) Capability name.

    function weplugins_modify_auth_object_type_sub_type_meta_meta_key_defaults($allowed, $meta_key, $post_id, $user_id, $cap, $caps) {

        // You can modify the $allowed variable conditionally too if you want.
        return $allowed; 
    }

        if ($meta_key == 'custom_meta_key') {
            $allowed = true; // Allow for this specific meta key
        }
        return $allowed;
    }
    // Add the filter
    add_filter("auth_object_type_sub_type_meta_meta_key", "weplugins_modify_auth_based_on_meta_key", 10, 6);
