Display message to cart page only if it contains two products with a certain tag

[TCK]

Hi,

I want to make it so that a message displays at the top of the cart page if the customer has added two products with a praticular tag - the message would say that if they add one item to the cart then they would receive a £5 discount. I know I can use an app, but they all look a bit naff and I don't like pop-ups on the cart.

I have already tried using the following code taken from a website, the code is for displaying a message if they spend a certain amount more then they get free shipping.

{% comment %} Add this snippet to your theme's cart.liquid file before <form></form> {% endcomment %}
<div class="cart-alert">
  <h5>
  {% if cart.total_price < 4900 %}
    <span style="font-weight: 900; color: #9fa615;">Have your eye on anything else?</span> If you spend {{ 4900 | minus: cart.total_price | money }} more, you qualify for free U.S. shipping!
  {% else %}
    <span style="font-weight: 900; color: #9fa615;">Hooray!</span> Your order qualifies for free U.S. shipping! Enjoy the savings.
  {% endif %}
  </h5>
</div>

My plan was to alter that code to make it so that a different message is displayed when two items with the tag 'personalised message' are in the cart. I attempted this (see below) but it isn't working - I'm a complete beginner at coding!

{% comment %} Add this snippet to your theme's cart.liquid file before <form></form> {% endcomment %}
<div class="cart-alert">
  <h5>
  {% if item.product.tags contains 'zwparcel' and item.quantity = 2}
    <span style="font-weight: 900; color: #155E2C;">Have your eye on anything else?</span> If you add one more Zero Waste Parcel to your cart, you qualify for a £5 discount!
  {% endif %}
    {% endif %}
  </h5>
</div>

Can any one help to adjust it so that it works?

My website URL is zwparcels.thecleankilo.co.uk

Thanks
Tom

Hey there @TCK,

I don't see why the second code SHOULD WORK? I mean you've not added any popup code etc.? Please share the link where you got the first/unmodified code and also share what steps you took to post the code in your theme.

Since you are a complete beginner you'll probably need developer assistance getting this done. You can contact me if you need my help.

Hi UmairA,

Don't worry about it - I went for static line of text for now.

I didn't particularly want it to be a pop-up like a light box, just for the text to appear if they added two qualifying items to the cart.

Thanks for your help anyway!

Tom
