在 Shopify 中分配条件全局液体变量

Question

I'm using trying to display shopify content based on the local domain it's using. To do this I've got the below which works fine:

{% if request.host contains 'co.nz' %}
  {% assign site_currency = "NZ" %}
{% endif %}

The problem is that variables seem to only work within the one snippet/template/layout file prior to being compiled, and what Shopify classes as a global variable is in fact just a value from the theme settings and therefore can't be conditional.

I've tried '{% assign scope = 'page' %}' which apparently works after compilation but I can't get it to work and there's very little documentation.

Does anyone know how I can declare this variable just once and then reference it throughout my theme?

Thanks!

Answer 1

Shopify global variables are only the objects specified here - https://shopify.dev/docs/themes/liquid/reference/objects

Only way to acheieve a global reference functionality without referencing through snippets is by storing it in the cart.attributes via JS, but that requires a page refresh to take effect.

Create a snippet or just paste the code above {{ content_for_layout }} in theme.liquid

{% comment %} /snippets/global-vars.liquid {% endcomment %}

{% if request.host contains 'co.nz' %}
  {% assign site_currency = "NZ" %}
{% endif %}

If you have few different currencies I suggest that you look into using case/when , here are the docs.

{% comment %} /layout/theme.liquid {% endcomment %}

...

{% include 'global-vars' %}
{% comment %} this should print the currency {% endcomment %}
{{ site_currency }} 
{{ content_for_layout }}
