Javascript to check if it Product Exists in Shopping Cart

[sellmethemoney]

Hello,

I'm fairly new here at shopsite and I have a question.

Do any of you have a Javascript sample that can be added to a template in order to stop a customer from ordering the same product twice?

We need our customers to be able to order only 1 of each of our products. We already set the maximum quantity to 1 and the customer cannot change the total once it's been ordered.

We have Shopsite Pro version 10.

Thanks!

This should work:

Code: Select all

var x = {}, len = ss_sku.length;
for (var i = 0; i < len; i++) {
  if ((x[ss_sku[i]] === true) && (button == "8")) {
    alert("Only ONE of each item is allowed to be ordered.");
    return false;
  }
  x[ss_sku[i]] = true;
}

Put the code in the textbox "Javascript added at start of built-in CheckIt function:" under Commerce Setup -> Shopping Cart

And it did beautifully!!

Thanks Rob.

Is there a way to limit this to 2 particular sku #?

I only have 2 products that they can order only 1 of at a time.
