below is the php code to check for errors after the input form.
and how to send form results that there is no error to result.php

here is index.php

<?php 
if ($_POST["_submit_check"]) {
    if ($form_errors = validate_form()) {
    show_form($form_errors);
    } else {
process_form();

print<<<_HTML_
<form method="POST" action="$_SERVER[PHP_SELF]">

Answer 1

you can do it with HTTP GET variables

header('Location: result.php?name='.$_POST['my_name']);

in result.php

you can see the value

echo $_GET['name'];
