Session Variables

 

When they visit the index.php assign a unique session variable, then on the other page is the variable is not set redirect them\give them an error.

You could just check the $_SERVER['HTTP_REFERER'] variable like this;

 

if($_SERVER['HTTP_REFERER'] != 'index.php') {
     echo "Error. I'm going to stop working now...";
     return;
     }

// Now carry on with the rest of your script...

The referrer is not always set, and can be forged.

[sylvertwst]

maybe change the link to an input(on index.php) and set a variable that you can call to check if the user came from the index on the next page?

[joecooper]

ive gone for the http_referer one for now.

 

but the link that it clicks though might be index.php?module=something

 

and so doent always work.

Use sessions -- much more reliable than the http_referer

 

In the index.php script:

<?php
session_start();
$_SESSION['coming_from'] = 'index.php';
?>

In the second script:

<?php
session_start();
if ($_SESSION['coming_from'] != 'index.php') header('location: index.php'); //put them back to index.php
?>
