The wp_error_added hook is a specific hook within WordPress that allows developers to perform actions or add custom functionality when an error is added to the WordPress error object.
Understanding the Hook: wp_error_added

Hook Doesn’t Work: wp_error_added
If the wp_error_added hook doesn’t seem to be working, it could be due to a few different reasons. First, ensure that the wp_add_error() function is being called and that errors are being added to the error object. Additionally, check that the hook is being used correctly and that there are no conflicts with other hooks or functions.
Best Practices & Usage Notes (if applicable): wp_error_added

“`php
function custom_error_handler( $code, $message ) {
// Perform custom actions when an error is added
}
