Passing a variable to a PHP payment processor

[Visualeyes]

Hello all


I'm trying to use a payment processor to pick up a hidden field in my form. I can't however, pass a value.


I want to raise a variable called passnodecimal and pass it to the payment processor. The payment processor is written in PHP so I have used $TEMPLATEURL to tell formmail where to send the data.


In may main form I have specified:


<input type="hidden" name="passnodecimal" value="2500">


In formail.php I have specified:


$SESSION_ACCESS = array("passnodecimal");


In the sample PHP form supplied by the payment processor, a part reads:


/*
In this example these values are hardcoded. In reality you may pass
these values from another script or take it from a database.
*/
$amount = "3000";


So I have changed it to:


$amount = $_SESSION["passnodecimal"];


…after which it will be concatenated with a few other variables in the PHP and mangled into an MD5 hash.


This is the only value I need to pass, since the others are non-changing (currency, merchant number etc) or generated on-the-fly by the PHP itself (timestamp, order ID etc).


How can I get that value passed across? I know its something to do with session variables, but I'm stumped! Can anyone help?


Thanks

I solved it- I just thought I'd post here in case anyone else had my problem.

I needed to place:

<?php session_start(); ?>

In my goodtemplate.php. And it needed to be right at the top, It didn't work further down the PHP page which is why I was getting confused...
