If you look at the IPN field reference at https://cms.paypal.com/uk/cgi-bin/?cmd=_render-content&content_ID=developer/e_howto_admin_IPNReference it says there is a limit of 255 characters. What you’re attempting to do is extremely bad practice. You’re much better off generating a hash that is unqiue to your backoffice processes and pass that across. Then, in your IPN listener script you’d retreieve this and do all you backoffice stuff.

Hi,
Im using a similar method to yours but im also trying to pass a long textfield which a user will enter via a text editor. However when i use the php explode function within the ipn page i realise that only a couple of lines of text is stored and the rest dissappears.

Does the explode function have a limit to the amount of words that can be stored by a variable within the array?

Also cant we just pass an array through the custom variable instead of passing a string?

Cheers

@mark Well that would come directly from your php logic, I've just used fixed values as it's an example. So say for your shipping ID your script would probably look different, E.g. $shipping_method_id = $basket->getShippingMethodID($session);

How do you get the values of the text fields – coupon code etc into those variables
for them to be then included in the array?
