Shopify液体获取相关的博客文章

问题描述

在shopify中，我正在使用液体模板来获取与其产品相关的博客帖子，如下所示：

  < UL> 
 {％为blogs.blog.articles％中的文章％} 
 {％if article.tags包含product.handle％} 
< li>< a href ={{article。 url}}>< p> {{article.title}}< / p>< / a>< / li> 
 {％endif％} 
 {％endfor％} 
< / ul> 
  

但是，如果没有相关帖子，我想显示一条消息，例如无相关帖子！

我的问题是我该怎么做？我曾打算试图将文章放入一个数组中，并测试它是否为空，但是我很难发现它是如何完成的。

谢谢！

解决方案

试试这样：

  {％assign related_posts =％} 
 
 {blog for blogs.blog.articles％中的文章％} 
 {％if article.tags包含product.handle％} 
 {％capture post％} 
< li>< a href ={{article.url}}>< p> {{article.title}}< / p>< / a> ;< /锂> 
 {％endcapture％} 
 {％assign related_posts = related_posts | append：post％} 
 {％endif％} 
 {％endfor％} 
 
 {％if related_posts.size> 0％} 
< ul> {{related_posts}}< / ul> 
 {％else％} 
没有相关帖子！ 
 {％endif％} 
  

In shopify I am using liquid templating to get blog posts which are related to products by their tags, like so:

<ul>
{% for article in blogs.blog.articles %}
    {% if article.tags contains product.handle %}
        <li><a href="{{ article.url }}"><p>{{ article.title }}</p></a></li>
    {% endif %}
{% endfor %}
</ul>

However, if there are no related posts, I would like to display a message such as "No related posts!"

My question is how would I do that? I have contemplated trying to get the articles into an array and testing if it is empty, but I am having difficulty finding out how this is done.

Thanks!

解决方案

Try something like this:

{% assign related_posts = "" %}

{% for article in blogs.blog.articles %}
  {% if article.tags contains product.handle %}
    {% capture post %}
      <li><a href="{{ article.url }}"><p>{{ article.title }}</p></a></li>
    {% endcapture %}
    {% assign related_posts = related_posts | append:post %}
  {% endif %}
{% endfor %}

{% if related_posts.size > 0 %}
  <ul> {{ related_posts }} </ul>
{% else %}
  No related posts!
{% endif %}
