Getting Invoiceid on callback page

[doktorbune]

Hello

 

At the begininng our gateway was sending our invoiceid to us back and we were using it to define the invoiceid. But yesterday they changed the returned values and now there are no more invoiceid returns.

 

I try to get the invoiceid with sessions and i tried

 

on capture page

 

$_SESSION['myinvoice'] = $params['invoiceid'];

 

and then

 

on callbackpage

 

$invoiceid = $_SESSION['myinvoice'];

 

but that doesnot work. Is there a simple method for this ?
