 * Credit: Forminator support
 * 
 * Function to extend Forminator functionality
 * 
 * This can be added as an MU Plugin or custom plugin. Or if you must, it should work in functions.php (run a check that forminator exists / is activated first)
 * for example:      if ( class_exists('Forminator')){
 * 
 * 
 * if a form is submitted with no To: address defined in the email (routing) notification then send a message to notify of this issue
 * it will include the form submission ID, the form ID, a link to view the form submissions and the page where the form was submitted (useful for multi form scenarios) 
 * Finally it will give you the submitted form data and a link to review the forms configuration.
 * 
 * credit to forminator support team for initial help: https://wordpress.org/support/topic/idiot-proofing-the-email-routing-of-a-form/
 * 
 * Make sure to change the $recipients array to your chosen email addresses or this won't work. 
 * 
 *  ## If you modify or re-use this code please credit me just like I credited The Forminator support team for their initial help.  ##
