Shopify液体：我怎样才能有条件包括Shopify液体片段？ [英] Shopify liquid: How can I conditionally include snippets in Shopify liquid?

问题描述

我想包括在模板但前提是片段文件中存在的一个片段。有没有什么办法能做到吗？

I would like to include a snippet in a template but only if the snippet file exist. Is there any way I can do it?

现在我只是用：

{% include 'snippetName' %}

但是，这引发错误：

But this throws the error:

Liquid error: Could not find asset snippets/snippetName.liquid

我需要这样一个功能的原因是因为我有一个后台进程以后添加片段。

The reason I need such a functionality is because I have a background process that adds the snippet later on.

推荐答案

有这个问题我自己。这是我的解决方案：

Had this problem myself. This was my solution:

{% capture the_snippet_content %}{% include the_snippet %}{% endcapture %}
{% unless the_snippet_content contains "Liquid error" %}
  {% include reviews_snippet %}
{% endunless %}

基本上捕捉片段的内容作为一个变量。
如果没有片段Shopify生成错误：

Basically capture the snippet’s content as a variable. If there is no snippet Shopify generates the error:

液体错误：找不到资产
  片段/卡罗琳·弗林特-reviews.liquid

Liquid error: Could not find asset snippets/caroline-flint-reviews.liquid

因此​​，检查，看它是否是生成了...如果这样不打印的代码段
：D

So check to see if it’s generated that… if so don’t print the snippet :D

当然，如果你打算你的片段，包括液体错误这样会破坏或者Shopify曾经更改错误信息。

Of course this would break if you intended your snippet to include "Liquid error" or if Shopify ever change the error message.
