is_protected_meta filter
Filters whether a meta key is considered protected. To use is_protected_meta 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. At WePlugins, it’s always better to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.
In the live examples, we have defined a function modify_is_protected_meta_defaults which takes 3 parameters and we registered using add_filter. The first parameter is_protected_meta is the name of the hook, the second parameter modify_is_protected_meta_defaults is the name of the function that needs to be called, the 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 is_protected_meta filter.
Parameters
Example 1: Basic Usage
Here’s a basic example of how you can use this hook to protect specific meta keys.
function weplugins_my_meta_is_protected_meta( $protected, $meta_key, $meta_type ) {
switch ($meta_key) {
case 'my_first_meta':
$protected = true;
break;
case 'my_second_meta':
$protected = true;
break;
}
return $protected;
}
add_filter( 'is_protected_meta', 'weplugins_my_meta_is_protected_meta', 10, 3 );
Example 2: Custom Functionality
Modify the $protected variable according to your website requirements and return this variable. You can modify it conditionally too if you want.
function weplugins_modify_is_protected_meta_defaults($protected, $meta_key, $meta_type) {
// Custom logic here
return $protected;
}
add_filter( "is_protected_meta", "weplugins_modify_is_protected_meta_defaults", 10, 3 );
Example 3: Removing a Hook
To remove a hook callback, use the example below. Ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.
remove_filter( "is_protected_meta", "weplugins_modify_is_protected_meta_defaults", 10, 3 );
