Hi there,

I am looking to set up a promo code whereby if customers add 2 or more items to their basket, they can receive 20% off the total order.

I have set the purchased quantity to 2, and the percentage off to 20 (see screenshot attached).

Problem is when I submit, there is an error which says: You must add more items to use this discount.

Any ideas?

Many thanks
Simon

You’d like it to work as a buy ANY 2 items and get X off. It doesn’t do that. It’s only a buy X of a specific qualifying entry id and get an amount off. What you want, I take it, is to buy X or more products of any kind and get a discount right?

We’d have to modify one of the existing plugins to do that. Wouldn’t take much effort though. I’ spent a few minutes making this. It’s untested, but you can try it out.

Wow, thank you Chris!

How do I install this? (Sorry)

Thanks Chris, this works but only if I add two different items to the cart. If I add two of the same item, the discount use doesn’t work, and it doesn’t produce an error message.

Is there anything I can do?

It’s not an error… so it won’t produce a message. It’s only looking at unique items in the cart. Is it your goal to look at quantities as well? If so, the plugin would need to be modified slightly.

Sorry Chris,  that’s my fault I didn’t explain it well.

Yes what I was after was quantities. So if the cart has 2 or more of any item (even just two of the same item), it would then allow the discount code.

In the discount plugin, change

  $count = count($this->core->cart->items());

to

$count = $this->core->cart->count_all();

Perfect, thank you very much Chris
