This post is not a tutorial, it’s more of a note for myself that I can refer to in the future. 🙂

In Liquid, when you use the {% capture %} tag, the variable that you capture becomes a string. As such, if you’re setting up a counter like in the example below, you must apply a math filter on it after to convert it back into a float/integer.

{% assign num = 0 %}


{% for product in product.collections %}
   {% if product.tags contains "special" %}
       {% capture temp %}{{ num | plus: 1 }}{% endcapture %} 
   {% endif %}
   
{% assign num = temp %}
{% endfor %}


{% assign num = num | plus: 0 %}

{% if num > 5 %}
You have more than 5 special products, hooray!
{% endif %}

Thanks as usual to Caro for showing me the ways!

THE END
