How to add custom message using tags on collection page in spotlight theme?

Shopify Discussion

Topic summary

A user is trying to display custom messages on collection pages in Shopify’s Spotlight theme based on product tags. They successfully implemented this on individual product pages using main-product.liquid with a loop checking for tags containing ‘newMessage:’. However, the same approach isn’t working when applied to card-product.liquid for collection pages.

Current Issue:

  • The message displays correctly on product pages
  • The message doesn’t appear on collection pages under product cards
  • Related products show the message, but it doesn’t apply to the specific tagged product

Attempted Solutions:

  • Initial suggestion to use card_product.tags in the liquid file
  • Follow-up recommendation to modify the code by looping through card_product.tags instead of product.tags

The discussion remains ongoing with troubleshooting focused on adapting the working product page code for collection page product cards.

Hi @mzwa

Dan here from Ryviu: Product Reviews @& QA app.

You can use this code in your card-product.liquid file

{% if card_product.tags contains 'your tag'  %}
your message
{% endif %}

Unfortunately no changes with the code you gave. I used the following code on the main-product.liquid for the message on the product page which worked successfully.

{% for tag in product.tags %}

{% if tag contains ‘newMessage:’ %}

{{ tag | remove:‘newMessage:’}}

{% endif %}

{% endfor %}

When I put this in the card-product.liquid file I don’t see the message it in the collection page. I do see a message in the product page on the related products (the same message displayed under the product page on that particular product page ). This message under the related products doesn’t apply to that particular product. Please help

You can try to edit this

{% for tag in card_product.tags %} 
 {% if tag contains 'newMessage:' %} 
  
    {{ tag | remove:'newMessage:'}} 
  
  {% endif %}
{% endfor %}
