javascript - 尝试在shopify中创建幻灯片放映变体

Question

我是 Shopify 新手，我正在尝试创建一个带有幻灯片变体的网站。我已经设法编写了这段代码，但出现以下错误第 247 行 — Liquid 语法错误:“schema”标签不得嵌套在其他标签内。

该代码旨在使用应用程序 Flex 应用程序将变体创建为幻灯片放映。

有人知道我做错了吗？

Answer 1

{% schema %} tag与 Shopify 的“sectioned themes”一起引入。我可以看到您的 Shopify 主题正在使用“Sections”，因为您的代码中引用了 section 变量!

由于在问题代码中搜索 {% schema %} 不会返回任何结果，因此我必须得出结论，语法错误源自不同的文件。 (可能包括带有 {% section 'product' %} directive 的 product.liquid 文件。

在有关“Using theme sections ”的 Shopify 主题文档中，我们看到 {% schema %} 标签位于 sections/ 文件夹内的模板中在主题的目录结构中。在这种情况下，我期望在 sections/product.liquid 中找到导致语法错误的嵌套标签。
