html - 相关产品未正确显示

Question

我正在尝试在我的一个 shopify 商店中生成相关产品，它在某些产品上显示但大部分没有，我想要的是，首先通过匹配供应商/品牌显示相关产品，如果找不到则显示相同的产品类别:

有人可以建议如何处理这个吗？

<div class="related-products row">
{% assign vendor = product.vendor %}
{% assign vendor_handle = vendor | handleize %}

{% assign handle = product.handle %}
<h4 style="text-align:left;">More in this collection</h4>
{% assign counter = '' %}
{% for product in collections[vendor_handle].all_products %}
  {% if vendor == product.vendor and counter.size < 4 and handle != product.handle %}
  {% capture temp %}{{ counter }}*{% endcapture %}
  {% assign counter = temp %}
  <div class="col-md-3 col-sm-3 col-xs-12">
    <div class="reveal">
      <a href="{{ product.url | within: collection }}" title="{{ product.title }}">
        <img src="{{ product.images.first | product_img_url: 'large' }}" class="img-responsive" alt="{{ product.title }}" />
      </a>
    </div>
    <a href="{{ prod.url | within: collection }}" title="{{ prod.title | escape }}">
        {{ product.title | escape }}
    </a>
  </div>
  {% endif %} 
{% endfor %}
</div>

您正在使用以下行更改主要产品

{% for product in collections[vendor_handle].all_products %}

prod 是什么？

尝试以下操作

<div class="related-products row">
{% assign vendor = product.vendor %}
{% assign vendor_handle = vendor | handleize %}

{% assign handle = product.handle %}
<h4 style="text-align:left;">More in this collection</h4>
{% assign counter = 0 %}
{% for coll_product in collections[vendor_handle].all_products %}
  {% if vendor == coll_product.vendor and counter < 4 and handle != coll_product.handle %}
  {% assign counter = counter | plus: 1 %}
  <div class="col-md-3 col-sm-3 col-xs-12">
    <div class="reveal">
      <a href="{{ coll_product.url | within: collection }}" title="{{ product.title }}">
        <img src="{{ coll_product.images.first | product_img_url: 'large' }}" class="img-responsive" alt="{{ coll_product.title }}" />
      </a>
    </div>
    <a href="{{ coll_product.url | within: collection }}" title="{{ coll_product.title | escape }}">
        {{ coll_product.title | escape }}
    </a>
  </div>
  {% endif %} 
{% endfor %}
</div>
