Need help with PayPal URLs

[eluser]Akinzekeel[/eluser]
Well I actually found a dirty workaround for this problem, however I haven't posted it here because I am still hoping that someone will come up with a better solution.

Anyway, here's how I did it:
1. In your .htaccess, add an exception for "paypal" (i.e. any URL starting with paypal will not get rewritten to index.php). Example:

Code:

RewriteCond $1 !^(index\.php|res|robots\.txt|paypal)

2. Create two new files in the root directory (where your index.php is located) called "paypal.php" and "paypal_cancel.php" and insert the following PHP code:

Code:

// paypal.php
$url = $_SERVER["SERVER_NAME"].'/order/paypal/'.$_GET['token'];
header("Cache-Control: max-age=0, must-revalidate");
header("Location: http://$url", TRUE, 301);

Code:

// paypal_cancel.php
$url = $_SERVER["SERVER_NAME"].'/order/cart/'.$_GET['token'];
header("Cache-Control: max-age=0, must-revalidate");
header("Location: http://$url", TRUE, 301);

The segment-based URL in the first-line is the URL of your "success" (=paypal.php) or "cancel" (=paypal_cancel.php) page.

3. In your CI script which uses paypal, define the success and cancel URL like http://example.com/paypal.php which would then result in http://example.com/paypal.php?token=ABCD-1234567890 which will ultimately be redirected to http://example.com/order/paypal/ABCD-1234567890
