How to use auth_object_type_meta_meta_key filter in WordPress

auth_object_type_meta_meta_key filter

Return true to have the mapped meta caps from edit_{$object_type} apply.

To use auth_object_type_meta_meta_key filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

WePlugins always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function weplugins_modify_auth_object_type_meta_meta_key_defaults which takes 6 parameters and we registered using add_filter. The first parameter auth_object_type_meta_meta_key is the name of the hook, The second parameter weplugins_modify_auth_object_type_meta_meta_key_defaults is the name of the function which needs to be called, third parameter is the priority of calling the hook if the same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_filter to remove auth_object_type_meta_meta_key filter.

Parameters

Below are the 6 parameters required to use this hook.

• $allowed : (bool) Whether the user can add the object meta. Default false.
• $meta_key : (string) The meta key.
• $object_id : (int) Object ID.
• $user_id : (int) User ID.
• $cap : (string) Capability name.
• $caps : (string[]) Array of the user’s capabilities.

Live Examples

Example 1: Basic Usage

Below is an example of how you can use this hook.

    function weplugins_modify_auth_object_type_meta_meta_key_defaults($allowed, $meta_key, $object_id, $user_id, $cap, $caps) { 
        // Update the $allowed variable according to your website requirements and return this variable. You can modify the $allowed variable conditionally too if you want.
        return $allowed; 
    }
    // add the filter
    add_filter( "auth_object_type_meta_meta_key", "weplugins_modify_auth_object_type_meta_meta_key_defaults", 10, 6 );
    

Example 2: Conditional Modification

This example demonstrates conditionally modifying the $allowed variable based on the meta key.

    function weplugins_modify_auth_object_type_meta_meta_key_defaults($allowed, $meta_key, $object_id, $user_id, $cap, $caps) { 
        if ($meta_key == 'special_key') {
            $allowed = true;
        }
        return $allowed; 
    }
    // add the filter
    add_filter( "auth_object_type_meta_meta_key", "weplugins_modify_auth_object_type_meta_meta_key_defaults", 10, 6 );
    

Example 3: Removing a Hook Callback

To remove a hook callback, use the example below.

    // remove the filter
    remove_filter( "auth_object_type_meta_meta_key", "weplugins_modify_auth_object_type_meta_meta_key_defaults", 10, 6 );
    

Please make sure to provide the same callback function name, priority, and number of arguments while removing the hook callback.
