Question

我已经建立了一个液体模板，用于比较当前产品的标签和商店中所有其他产品的标签，并在页面底部显示四个相关产品。

它有效，但我认为我做得非常低效。有没有办法让这项工作更好一点？

{% if settings.products_per_row == "4" %}
{% assign number_of_related_products_to_show = 4 %}
{% elsif settings.products_per_row == "3" %}
{% assign number_of_related_products_to_show = 3 %}
{% else %}
{% assign number_of_related_products_to_show = 2 %}
{% endif %}

{% assign number_of_related_products_to_fetch = number_of_related_products_to_show | plus: 1 %}
{% assign current_product_tags = product.tags %}

{% for c in collections %}
    {% if c.handle == 'all' %}
        {% assign collection_all = c %}
    {% endif %}
{% endfor %}

{% assign found_first_match = false %}
{% assign found_second_match = false %}
{% paginate collection_all.products by 1000 %}
{% for product in collection_all.products %}
{% for tag in product.tags %}
    {% if current_product_tags contains tag and found_first_match == false and tag != 'Made in USA' %}
        {% assign found_first_match = true %}
        {% assign first_match = tag %}
    {% endif %}
    {% if current_product_tags contains tag and found_first_match == true and tag != first_match and tag != 'Made in USA' %}
        {% assign found_second_match = true %}
        {% assign second_match = tag %}
    {% endif %}
{% endfor %}
{% endfor %}
{% endpaginate %}

{% assign matches_found = false %}
{% assign current_product = product %}
{% assign current_product_found = false %}

{% paginate collection_all.products by 1000 %}
{% for product in collection_all.products %}
  {% if product.handle == current_product.handle %}
    {% assign current_product_found = true %}
  {% else %}
    {% if product.tags contains first_match %}
      {% unless current_product_found == false and forloop.last %}
        {% assign matches_found = true %}
      {% endunless %}
    {% endif %}
    {% if product.tags contains second_match and matches_found == false  %}
      {% unless current_product_found == false and forloop.last %}
        {% assign matches_found = true %}
      {% endunless %}
    {% endif %}
  {% endif %}
{% endfor %}
{% endpaginate %}

{% if matches_found == true %}

<div class="row">
  <div class="span12">
    <h3 class="collection-title">Related products</h3>
  </div>
</div> 

<div class="row products">

{% paginate collection_all.products by 1000 %}
{% for product in collection_all.products %}
  {% if product.handle == current_product.handle %}
    {% assign current_product_found = true %}
  {% else %}
    {% if product.tags contains first_match %}
      {% unless current_product_found == false and forloop.last %}
        {% include 'related-product-loop' with collection.handle %}
        {% assign matched_product = product.title %}
      {% endunless %}
    {% endif %}
    {% if product.tags contains second_match %}
      {% unless current_product_found == false and forloop.last or matched_product == product.title %}
        {% include 'related-product-loop' with collection.handle %}
      {% endunless %}
    {% endif %}
  {% endif %}
{% endfor %}
{% endpaginate %}

</div>

{% endif %}

{{ 'jquery.pick.js' | asset_url | script_tag }}
<script type="text/javascript" charset="utf-8">
//<![CDATA[
var howMany = {{ number_of_related_products_to_show }};
jQuery(function() {
  jQuery('.products .product').pick(howMany);
});
//]]>
</script>

我正在使用jquery.pick.js随机显示四种产品。

思想？

我建议您在Shopify wiki上查看这篇文章：Related Products。

第3. Finding a relevant collection节中使用的方法可能是实现相关产品的更简洁方法。但是，如果您需要使用产品标签，则可以在4. Using product tags部分中解释如何执行此操作。

编辑：也许您的代码可以简化为类似的东西。它与上面的内容非常相似，但只是通过所有产品将其减少到一个循环，而不是三个。

{% if settings.products_per_row == "3" or settings.products_per_row == "4" %}
  {% assign number_of_related_products_to_show = settings.products_per_row | times: 1 %}
{% else %}
  {% assign number_of_related_products_to_show = 2 %}
{% endif %}

{% assign current_product = product %}
{% assign current_product_tags = product.tags %}
{% assign found_first_match = false %}
{% assign found_second_match = false %}
{% assign first_related_product = true %}

{% paginate collections.all.products by 1000 %}
{% for product in collections.all.products %}
  {% unless product.handle == current_product.handle %}
    {% for tag in product.tags %}
      {% if current_product_tags contains tag and tag != 'Made in USA' %}
        {% if found_first_match == false %}
          {% assign found_first_match = true %}
          {% assign first_match = tag %}
        {% elsif found_second_match == false %}
          {% assign found_second_match = true %}
          {% assign second_match = tag %}
        {% endif %}
      {% endif %}
    {% endfor %}

    {% if found_first_match == true %}
      {% if first_related_product == true %}
        {% assign first_related_product == false %}

        <div class="row">
          <div class="span12">
            <h3 class="collection-title">Related products</h3>
          </div>
        </div>
        <div class="row products">

      {% endif %}
      {% if product.tags contains first_match or product.tags contains second_match %}
        {% include 'related-product-loop' with collection.handle %}
      {% endif %}
    {% endif %}
  {% endunless %}
{% endfor %}
{% if first_related_product == false %} </div> {% endif %}
{% endpaginate %}

{{ 'jquery.pick.js' | asset_url | script_tag }}
<script type="text/javascript" charset="utf-8">
//<![CDATA[
  var howMany = {{ number_of_related_products_to_show }};
  jQuery(function() {
    jQuery('.products .product').pick(howMany);
  });
//]]>
</script>

此代码位于要点here。我包含了2个文件，第二个选项在产品中使用了2个循环，但可能更具可读性。（我无法在两者之间作出决定，因此我将两者都包括在内。）
