Test for Item in Cart to Prevent Adding Another

Is there a way to hide a product from a dynamic Repeating section unless a product that is required to be ordered has been placed in the cart? I have ItemIDs and playerIDs available in the cart; the test would look for a different playerID and the inclusion of a specific itemID.

Or is there a better way to test and implement?

Thanks,

Mike

you can test for an item by ID using inCart:
$cartObName->InCart("<ID Value>") == true

or you can do a conditional Total for a other columns
$cartObName->ConditionalTotal("Quantity", "playerID", "<id value>") > 0)

I get the first one -- don't quite follow the second. What would <id value> represent??

the value you want to check for in the playerID column

conditionalTotal takes 3 arguments:
The column to total

The Conditional Column

The Value to check for


Say you had a color column and you wanted to now if any items where purchased with a color of red:


if($cartObName->ConditionalTotal("Quantity", "color", "red") > 0)) {
echo("there's a red item in the cart");
}

Got it.

I've been trying to use this test in a repeating region to hiwith minimal success. Would it be possible to test for a needed item in the cart by attaching the test to the AddtoCart function in the cart definition, and if the required item is missing to throw a JS alert notifying the user they need to have a specified item prior to selecting this one?

I'm just looking for a clean way to let users know of the requirement.

Thanks, Jason. . .

"attaching the test to the AddtoCart function in the cart definition,"

Im not sure why that would be any cleaner than adding the notice beside the item, on the catalog page.

Im sure it would be possible to send a javascript alert, but would take custom coding to accomplish, this sort of customization is beyond the scope of the public forum, we could help implement this in a premiere incident:
