What is WordPress Hook: set_user_role

The set_user_role hook in WordPress is used to perform actions when a user’s role is changed. This can be useful for various scenarios such as sending notifications, updating user data, or triggering custom functions based on role changes.

Understanding the Hook: set_user_role

The set_user_role hook is located within the wp_update_user() function in WordPress. This function is called when a user’s role is updated, and the set_user_role hook allows developers to add their own custom code to be executed at this specific point in the process.

Hook Parameters (if applicable): set_user_role

The set_user_role hook accepts three parameters: $user_id, $role, and $old_roles. The $user_id parameter is the ID of the user whose role is being changed, $role is the new role being assigned to the user, and $old_roles is an array of the user’s previous roles before the change.

Hook Doesn’t Work: set_user_role

If the set_user_role hook doesn’t seem to be working, it could be due to incorrect implementation or conflicts with other plugins or themes. It’s important to double-check the code where the hook is being used and ensure that it is properly registered and functioning as expected.

Best Practices & Usage Notes (if applicable): set_user_role

When using the set_user_role hook, it’s important to consider the potential impact on user data and system performance. It’s recommended to only perform lightweight and essential tasks within the hook to avoid slowing down the user role update process.

Usage Example: set_user_role

“`php
function custom_user_role_update( $user_id, $role, $old_roles ) {
// Add custom code here to perform actions when a user’s role is changed
}
add_action( ‘set_user_role’, ‘custom_user_role_update’, 10, 3 );
“`
