Question

我需要为供应商是特定供应商的产品运行一些逻辑，并且如果产品含量不足，请禁用“添加免费示例”按钮。 （已经设置了禁用该按钮的代码），这是以下代码：

{%- comment -%}SAMPLE LOGIC{%- endcomment -%}
{% if has_free_sample %}
  {%- comment -%} check if there is > 4 samples or an existing sample of the same in the cart {%- endcomment -%}
  {% assign maxSamples = false %}
  {% assign sampleInCart = false %}
  {% assign sampleCount = 0 %}
  {% for item in cart.items %}
    {% if size_option == item.variant_id %}
      {% assign sampleInCart = true %}
      {% break %}
    {% endif %}

    {%- comment -%}check if its a sample{%- endcomment -%}
    {% assign isASample = false %}
    {% for option in item.options_with_values %}
      {% if option.value contains 'Sample' %}
        {% assign isASample = true %}
        {% break %}
      {% endif %}
    {% endfor %}

    {% if isASample %}
      {% assign sampleCount = sampleCount | plus: 1 %}
      {% if sampleCount == 4 %}
        {% assign maxSamples = true %}
        {% break %}
      {% endif %}
    {% endif %}
  {% endfor %}

  {% assign isInStock = true %}
    {% if product.vendor == 'PS-Stock' and product.available == false %}
      {% assign isInStock = false %}
    {% endif %}


  {%- comment -%}ADD SAMPLE {%- endcomment -%}
  {% if maxSamples == false and sampleInCart == false and isInStock == true %}
    <input type="hidden" data-free-sample-quantity-input max="1"/>
    <button {% unless current_variant.available %}disabled{% endunless %} 
    data-product-form-submit
    data-in-stock-text="{{ 'products.product.add_to_cart' | t: unit: order_measurement }}"
    data-unavailable-text="{{ 'products.product.unavailable' | t }}"
    data-oos-text="{{ 'products.product.sold_out' | t }}"
    data-success-text="{{ 'products.product.added_to_cart' | t }}"
    data-add-to-cart
    data-atc-quantity-input="[data-free-sample-quantity-input]"
    data-atc-product-id="{{ size_option }}"
    data-is-sample="true"
    data-max-samples="{{ 'products.product.max_samples' | t }}"
    data-sample-added-text="{{ 'products.product.sample_added' | t }}"
    data-sample-added-error-toast-text="{{ 'products.product.sample_added_error_toast' | t }}"
    type="submit"
    class="btn--atc btn btn-primary">{{ 'products.product.add_to_cart_free_sample' | t }}</button>
  {% else %}
    <button 
      disabled
      data-max-samples="{{ 'products.product.max_samples' | t }}"
      data-in-stock-text="{{ 'products.product.add_to_cart' | t: unit: order_measurement }}"
      data-unavailable-text="{{ 'products.product.unavailable' | t }}"
      data-oos-text="{{ 'products.product.sold_out' | t }}"
      data-success-text="{{ 'products.product.added_to_cart' | t }}"
      data-atc-product-id="{{ size_option }}"
      data-is-sample="true"
      type="submit"
      class="btn--atc btn btn-primary">
      {% if maxSamples %}
        {{ 'products.product.max_samples' | t }}
      {% else %}
        {{ 'products.product.sample_added' | t }}
      {% endif %}
    </button>
  {% endif %}
{% endif %}

我觉得这个问题可能位于“ Isinstock”变量的某个地方，但不确定。我需要它仅在其某些供应商指定的供应商时才禁用该按钮，并且该产品不合时间
