WebAssist behaviors to IPN page
I was just reading this post because I am using the Ecart 4.x with ASP.
I have an IPN page that works great with single items.
However, when I use the Ecart for multiple items, the "item_number" is returning as blank from PayPal.
I noticed in the Ecart Checkout form that the "item_number" actually has an underscore after it, followed by the Ecart increment.
(<input type="hidden" name="item_number_<%=eCart1_Index+1%>" id="item_number_<%=eCart1_Index+1%>" value="<%=WA_eCart_DisplayInfo(eCart1, "ID")%>" />)
It posts to PayPal just fine. All the multiple items are displayed perfectly.
However, after payment, the IPN page gets nothing.
I have it returning to a "thank you" page, and the querystring shows "item_number" as equal to nothing. (i.e. &item_number= )
To what are you referring when you say that WebAssist behaviors could be added to an IPN page?
I assume that is true, somehow, but not sure how to do it.
Also... not sure how PayPal is returning the "item_number_ecart1_index+1" value/string.
