Hello Experts,

Do not get me wrong that's not how i validate my forms :-) but... i know how to echo an error message per form field. Yet i am trying to understand how this is possible to do this using the "foreach" loop and then echo an error message per field in case it is empty. Thank you so much!

<?php

   $contactName = htmlentities(trim($_POST["contactName"]));
   $contactPhone = htmlentities(trim($_POST["contactPhone"]));

   $requiredFields = array('$contactName', '$contactPhone');
   
   foreach ($requiredFields as $requiredField) {
      
     if ($requiredField === '') {

    ///////// if the $contactName is left empty then
    
     $err_contactName = "please enter your name";

   //////// if the $contactPhone is left empty then

     $err_contactPhone = "please enter your phone";
    }
?>
