Paypal Integration

[searls03]

I am using paypal to integrate a shopping cart into my site. I would like to know if anyone knows how paypal sends POST variables when there are multiple items. So my customer orders 2 items, I know how to get one item, but how does paypal send both? do they use an array? an item_name_1/2? how do they post back? does anyone here know?if you can help me, that would be awesome.

so I do use item_name1/2/3/etc....but how can I dynamically create this list is my next question then.

Without really knowing what you're doing, since you haven't really given any such information, a for loop perhaps?

for($i = 1; $i <= 5; $i++)
{
echo '<input type="hidden" name="item_name' . $i . '" />';
}

I thought about a for loop, but the issue here being that how do I know what number to end on....there could be 1 item, there could be 100 items ordered. I plan to insert into a database each item that is sold individually for tracking purposes. So I guess I am asking, does paypal send a variable of how many items were purchased? I have been looking and can't seem to find one.
