"Checkout_Process" Query - success & non-succe

[eureka]

I'm setting up pre-Nov '02 osC site with a payment gateway provider, they're modifing the cc.php payment module so my site "talks" to their server.

 

A few queries:

 

1. On a successful credit card transaction the provider's server calls back to checkout_success.php, what do they call back to if unsuccessful?

 

2. With my limited PHP, is the order details processed by checkout_process.php and written to SQL database regardless of what happens, success or unsuccess?

 

Please help.

:?

 

Mark.

They need to take a good look at one of the installed payment modules. authorize.net is a good example of one that goes thru all the hoops.

 

In general for an offsite payment processor you set the process_button function to set_up all the variables your payment processor requires. Also setting the $this->form_action_url to point to your payment processor site.

 

On return the processor should go back to checkout_process. They should return a an erro code either in a post or get var.

 

the before process function can then check for the existence of the error code and redirect

        tep_redirect(tep_href_link(FILENAME_CHECKOUT_PAYMENT, 'error_message=' . urlencode(MODULE_PROCESSOR_TEXT_ERROR_MESSAGE), 'SSL', true, false));

Thanks for your reply. I'll pass on the info onto my payment provider and see how we go.

It would be nice as well that if they do complete a solution, that that solution was made into a contribution. This would benefit them as much as it would benefit osCommerce.
