<?php
   function kou(){
       $Ul =$_POST['name'];
       echo "<script>document.getElementById('tt').value=' . $Ul . ';   </script>";
   }
   
   $UM =$_POST['name'];

  • 1. Input does not have onsubmit, the form element has. 2. JS cannot execute a PHP function just by running it. You need AJAX. Perhaps you mean `` – mplungjan Jul 09 '23 at 07:42
