worldpay submit (ASCII newline characters in URL)

norpel

hi,

I'm trying to POST some variables to worldpay to initiate a payment.

My variables seem to post ok, except for the address.
Worldpay asks that address lines are terminated by the ascii newline character &#10
The first line of the address appears in the worldpay page when I POST using this...

$submitstring = "name=".$_GET['name']."&............... more variables here........."&";
$address_submit = htmlentities($_GET['address1'])."&#10".htmlentities($_GET['address2'])."&#10".htmlentities($_GET['town']);

$submitstring .= $address_submit;
$url = "https://select.worldpay.com/wcc/purchase?";
header('Location:'.$url.$submitstring);

but subsequent lines don't.

I've tried encoding the &#10 using escape characters %26%2310; (%26==&, %23==#) but this doesn't seem to make any difference.

Can anyone see where I'm going wrong.

Many thanks for any help.

Hi,

the newline entity is &#10; (with 😉. An alternative might be the following:

$submitstring = "name=".urlencode($_GET['name'])."&............... more variables here.........&"; 
$submitstring .= urlencode($_GET['address1']."\n".$_GET['address2']."\n".$_GET['town']);
header("https://select.worldplay.com/wcc/purchase?$submitstring");

You need to use $POST instead of $GET if address1, address2 and town are coming from a form with method="post".

In the code the get variable name for the address might be missing. I didn't see any in your post (like ...&address=".urlencode(...))

hi tsinka,
thanks for your reply....
i actually had the ';' in at one stage, but took it out when testing and posting this as it didn't seem to make much difference when I was posting.

the funny thing is - I got the submit to work using the %26%23 escape characters but only without the ;

wierd - I don't quite know why, but it works.

thanks for the tip about the urlencode function, I didn't know about it and it looks like it will make future POSTs alot more reliable (and simple).

thanks for your help, alongside google, this forum and the people who post are lifesavers (or hair savers) for so many people

Glad to hear that you solved the problem 🙂
