This is one of the things sessions are used for. Store $_POST in a
session variable and set another variable as failed. Then on your
page1.php just check for the failed variable and if it is there
populate the form with the previous details. You can even include an
error message. The flow would be:
page1.php
session_start();
if(isset($_SESSION['status']) and $_SESSION['status'] == 'failed'){
$extract($_SEESION['post']);
unset($_SESSION);
//fill in form values ie <input type="text" name="name" value="<?php
echo $name?>">
}else{
//send blank form
}
page2.php
session_start();
//do validation
if($status == 'failed'){
$_SESSION['status'] = 'failed';
$_SESSION['post'] = $_POST;
//send redirect header
exit;
}else{
//do success stuff
}
