如何在Liquid中定义全局变量? [英] How to define global variables in Liquid?

问题描述

现在看来，我创建的变量无法跨文件通信.

Right now it seems variables I create can't communicate across files.

推荐答案

对于Liquid，您可以在包含项中传递变量

For Liquid you can pass a variable in the include

{%- assign global_var = "VALUE" -%}
{%- include 'YOUR_FILE' global_var: global_var  -%}

对于Shopify液体，您可以执行以下操作:

For Shopify liquid you can do the following:

有一个解决方法，您可以在主题设置中将全局变量设置为选项 config/settings_schema.json

There is a work around this, you can set the global variable in the theme settings as an option config/settings_schema.json

  {
    "type": "text",
    "id": "global_variable",
    "label": "global variable",
    "default": "Variable value"
  },

，您可以通过以下方式在临时文件中访问它:

and you can access it in the liquid files through

settings.global_variable

但是该值取决于您在主题设置中输入的内容.

But the value is depending on what you enter in the theme settings.

如果您需要更多动态方式，则可以通过ajax设置购物车属性，例如:

If you need more dynamic way, you can set cart attributes through ajax like:

    $.ajax({
      type: 'POST',
      url: '/cart/update.js',
      data: { attributes: {'global_variable': "MY_VALUE"} },
      dataType: 'json',
      success: function(cart) {
        location.reload();
      }
    });

然后通过以下方式在主题中的任何位置进行访问cart.attributes.global_variable但是每次购物车都是空的时候你必须更新它

And then access it any where in the theme through cart.attributes.global_variable But you have to update it each time the cart is empty
