I'm a first-time php user trying to implement the php scripts that they offer as downloads at the authorize.net site. I've read the SIM Implementation Guide they also offer as a download (a couple of times!) and tried to acquaint myself with basic php syntax,etc.,by poring over a couple of php manuals.
But I'm still kind of at sea about proper implementation protocols.
All I want to do is :
1.help my web client avoid having to pay for a shopping cart by using those SIM scripts to handle transactions for multiple items (no more than 8). Hopefully her checkout process can allow for her customers to pay for several items at once. (But if necessary she's willing to settle for a process which has her customers submitting each transaction individually.) But I am not sure how to modify the sim.php script to reflect her checkout process (whether it is a single item transaction or multiple.)
2.I just can't tell from reading the SIM Implementation Guide or scrutinizing the SIM php sample scripts I downloaded from authorize.net how to modify those scripts to handle multiple purchases at once; and...
3.how to send information for multiple "Descriptions" and "Amounts" to their payment gateway, for that matter,which would seem to be a real neccessity!
The sim.php page I've built her amounts to an Order Confirmation form with multiple fields to list up to 3 items at once and a submit button which sends the buyer to a Payment Form hosted by authorize.net.
Has anyone out there used these scripts successfully? Any helplful comments would be very appreciated!
Thanks!
Cheela
