Question

I am not using a pre-made shopping cart, I programming it myself. It works perfectly fine 99% of the time, but about once every couple months an order goes through for $0. I cannot figure out why. I make a test purchase with the same product and all the same info and I cannot get it to be $0 for me. I am not sure how to go about trouble shooting this, I do have a disclaimer saying that we do not honor erroneous prices. The client wants this to stop happening though. I am using PHP to do all of this. Since I cannot seem to duplicate the occurnace myself I am finding it hard to get to the bottom of the issue. Can anyone offer some advice on how to troubleshoot this?

Thanks!!

Ultimately, you’ll want to figure out why this is happening. Without seeing your code, I can’t really help you out much with that. In the short term though, why not just add a sanity check at the end of the checkout process?

if ( $final_price < 1 ) {     do_epic_fail(); // Show an error, whatever. }
