$_POST

Hi Guys,

 

I have 2 pages, a form (form.php), and a script (process.php). Now what I want to do is, if someone tries to directly access process.php then he will get redirected back to form.php, but if a user submitts a form via form.php then it will get processed by process.php - How can I do this ?

You could check the $_SERVER['HTTP_REFERER'], but this isn't 100% reliable.

 

You could set a session variable on form.php, and check for it on process.php. If it's not there, then they didn't go to form.php first. That solution only works once though.

 

Or, you could set a hidden variable to pass through, and check for that.

<input type="hidden" name="valid_user" value="true" />

 

Or, you could check that all the fields have been set (or at the least the ones that have to), and if they're not... send them back to form.php.

<?php
if(!isset($_POST['name']))
    header("Location: URL/form.php"); // They didn't enter their name or they came to process.php directly!

You could, as well, use something that makes sure the form was actually submitted:

 

if (isset($_POST['submit'])){
// all your code here
} else {
header("Location: form.php");
}
