如何通过标签显示相关产品 - shopify

Question

我的产品页面上有一个“相关产品”部分，基于'Vatage'主题。现在它显示了一个由“收集”相关的产品。是否有可能显示相关产品的相同标签？ 我试着用其他代码，但我失败了.. 请有人帮助我。

这是我的related-products.liquid代码。

谢谢。

{% capture number_of_related_products_to_fetch %}{{ number_of_related_products_to_show | plus: 1 }}{% endcapture %} 

{% if collection == null or collection.handle == 'frontpage' or collection.handle == 'all' %} 
{% assign found_a_collection = false %} 
{% for c in product.collections %} 
{% if found_a_collection == false and c.handle != 'frontpage' and c.handle != 'all' and c.all_products_count > 1 %} 
{% assign found_a_collection = true %} 
{% assign collection = c %} 
{% endif %} 
{% endfor %} 
{% endif %} 


<div class="desktop-12 mobile-3"> 


    <h4 class="section-title">{{ 'products.product.related_products' | t }}</h4> 

    <div id="product-loop"> 
    {% assign current_product_found = false %} 
    {% for prod in collection.products limit: 7 %} 
    {% if prod.title == product.title %} 
    {% assign current_product_found = true %} 
    {% else %} 
    {% unless current_product_found == false and forloop.last %} 
    <div class="product-index desktop-2 tablet-2 mobile-half" id="prod-{{ product.id }}" data-alpha="{{ prod.title }}" data-price="{{ prod.price }}"> 
     <a href="{{ prod.url | within: collection }}" title="{{ prod.title | escape }}"> 
     <img src="{{ prod.featured_image | product_img_url: 'large' }}" alt="{{ product.title | escape }}" /> 
     </a> 

     <div class="product-info"> 

     <div class="product-info-inner"> 
      <a href="{{ prod.url | within: collection }}"> 
      <h3>{{ prod.title }}</h3> 
      </a>   
      <div class="price"> 
      {% if product.price < prod.compare_at_price %} 
      <div class="onsale">{{ prod.price | money }}</div> 
      <div class="was">{{ prod.compare_at_price | money }}</div> 
      {% else %} 
      <div class="prod-price">{% if prod.price_varies %} {{ 'products.general.from' | t }} {{ prod.price_min | money }} - {{ prod.price_max | money }} {% else %}{{ prod.price | money }}{% endif %}</div> 
      {% endif %} 
      </div> 

     </div>
