I have a php page that does field validation. The form posts to itself in order to check which fields were not entered. Once the fields are properly entered, it is redirected to another page "abstract_page_2.php". Now once I am on the second page, I can no longer access the values that were previously filled in. What would be the alternative way of doing this since the header function doesn't seem to POST variables. I've just started using PHP and I'm kind of new to all this...I would greatly appreciate someone's help over this. Here is my code below (PHP & HTML).
<?php
session_start();
header("Cache-control: private");
$message = "";
$message2 = "";
$message3 = "";
$titleclass = "basictext";
$username = "";
if ($_POST['process'] == 1)
{
if ( (isset($_POST['Title'])) && (!empty($_POST['Title'])) )
{
//if it's all good then redirect...
header("location: abstract_page_2.php");
}
// else put in the error message
$message = "Please enter the TITLE of your presentation.";
$Title = $_POST['Title'];
$emailclass = "errortext";
}
?>
