When a customer submits a payment from the payment form, the payment goes through to Authorize.net (and is processed correctly) but they see a blank screen that prints the message order id number invalid.

The error message is generated from the ../photocart/anetres.php file when it cannot retrieve the x_invoice_num posted variable (see line #26). The anetres-script checks to see if the invoice/order is a number and because it's empty the script "dies". I inserted a javascript alert-box to try to display the variable and saw a blank box. Then, I commented out the line and the next error message (see line 28) displays "an error as occurred..." also verifying that they $_POST didn't pull the Order/Invoice ID number.

In the ../photocart/payment/payment.authorize.net.sim file, the variable x_invoice_num is passed in the form from $x_Invoice. I changed "hidden" to "text" to verify this. However "I think somehow" anetres.php is not able to pull in and read the variable and possibly others from $_POST["x_invoice_num"].

This issue seems identical to Sarah Ritter's (http://www.picturespro.com/support-forum/photo-cart/index.php?t=16976-issues-with-customers-placing-orders-and-getting-error-messages) and if we Google the error message at least 5 other photographer websites using PhotoCart display the same error message from anetres.php.

Has this issue been resolved and I'm just not finding the solution? Can you tell me where is the file that contains the "FORM" header information so I can check where it's being posted? Is there an intermediary file that process the "Send Payment" form variables, I'd like to test and see if it is getting and sending variables appropriately. Any help is much appreciated.

Is this something that was working fine then stop working? If so, any changes on the server you are hosting on or with authorize.net? We never found a solution for the other person.

Are you able to see any of the variables getting posted back to the anetres.php file like using the network console in Firefox (Ctrl + Shift + Q)

Hi Tim,

The Network/Console shows the variables are set and being passed - at least that's what it looks like to me. However, the $_POST array is empty when I insert a var_dump($GLOBALS) or print_r($_POST) in the script (anetres.php) just before the $_POST["x_invoice_num"] is called to set $order_id.

Have you asked authorize.net about this? It sounds like either authorize.net is not sending any data back or for some reason the data is being blocked by the server.
