prestashop - Prestashop 1.7 模板不传递变量

Question

我有一个我无法解决的问题。在 prestashop 1.7 中，我有一个名为 product.tpl 的 tpl 文件，其中除了各种数据外，我还使用以下代码调用了一个文件：

<div class="product-actions">
          {block name='product_buy'}
            <form action="{$urls.pages.cart}" method="post" id="add-to-cart-or-refresh">
              <input type="hidden" name="token" value="{$static_token}">
              <input type="hidden" name="id_product" value="{$product.id}" id="product_page_product_id">
              <input type="hidden" name="id_customization" value="{$product.customization_id}" id="product_customization_id">

              {block name='product_variants'}
                {include file='catalog/_partials/product-variants.tpl'}
              {/block}

              {block name='product_pack'}
                {if $packItems}
                  <section class="product-pack">
                    <h3 class="h4">{l s='This pack contains' d='Shop.Theme.Catalog'}</h3>
                    {foreach from=$packItems item="product_pack"}
                      {block name='product_miniature'}
                        {include file='catalog/_partials/miniatures/pack-product.tpl' product=$product_pack}
                      {/block}
                    {/foreach}
                </section>
                {/if}
              {/block}

              {block name='product_discounts'}
                {include file='catalog/_partials/product-discounts.tpl'}
              {/block}

              {block name='product_add_to_cart'}
                {include file='catalog/_partials/product-add-to-cart.tpl'}
              {/block}

              {block name='product_additional_info'}
                {include file='catalog/_partials/product-additional-info.tpl'}
              {/block}

              {block name='product_refresh'}
                <input class="product-refresh ps-hidden-by-js" name="refresh" type="submit" value="{l s='Refresh' d='Shop.Theme.Actions'}">
              {/block}
            </form>
          {/block}

        </div>

一切正常。

我最感兴趣的是这个块中提到的代码部分

{block name='product_variants'}
                {include file='catalog/_partials/product-variants.tpl'}
              {/block}

代码是：

<div class="product-variants">
  {foreach from=$groups key=id_attribute_group item=group}
    <div class="clearfix product-variants-item">
      <span class="control-label">{$group.name}</span>
      {if $group.group_type == 'select'}
        <select
          class="form-control form-control-select"
          id="group_{$id_attribute_group}"
          data-product-attribute="{$id_attribute_group}"
          name="group[{$id_attribute_group}]">
          {foreach from=$group.attributes key=id_attribute item=group_attribute}
            <option value="{$id_attribute}" title="{$group_attribute.name}"{if $group_attribute.selected} selected="selected"{/if}>{$group_attribute.name}</option>
          {/foreach}
        </select>
      {elseif $group.group_type == 'color'}
        <ul id="group_{$id_attribute_group}">
          {foreach from=$group.attributes key=id_attribute item=group_attribute}
            <li class="float-xs-left input-container">
              <label>
                <input class="input-color" type="radio" data-product-attribute="{$id_attribute_group}" name="group[{$id_attribute_group}]" value="{$id_attribute}"{if $group_attribute.selected} checked="checked"{/if}>
                <span
                  {if $group_attribute.html_color_code}class="color" style="background-color: {$group_attribute.html_color_code}" {/if}
                  {if $group_attribute.texture}class="color texture" style="background-image: url({$group_attribute.texture})" {/if}
                ><span class="sr-only">{$group_attribute.name}</span></span>
              </label>
            </li>
          {/foreach}
        </ul>
      {elseif $group.group_type == 'radio'}
        <ul id="group_{$id_attribute_group}">
          {foreach from=$group.attributes key=id_attribute item=group_attribute}
            <li class="input-container float-xs-left">
              <label>
                <input class="input-radio" type="radio" data-product-attribute="{$id_attribute_group}" name="group[{$id_attribute_group}]" value="{$id_attribute}"{if $group_attribute.selected} checked="checked"{/if}>
                <span class="radio-label">{$group_attribute.name}</span>
              </label>
            </li>
          {/foreach}
        </ul>
      {/if}
    </div>
  {/foreach}
</div>

然后我修改了模块 ps_featuredproducts 的 tpl 文件并在主文件“ps_featuredproducts.tpl”中，在 foreach 中我插入了一部分代码来显示变体和一些产品 html 设计。

发生的事情是我完美地可视化了格式，但是变量的所有值都没有让我看到它们，特别是这部分代码不起作用

<div class="product-variants">
  {foreach from=$groups key=id_attribute_group item=group}
    <div class="clearfix product-variants-item">
      <span class="control-label">{$group.name}</span>
      {if $group.group_type == 'select'}
        <select
          class="form-control form-control-select"
          id="group_{$id_attribute_group}"
          data-product-attribute="{$id_attribute_group}"
          name="group[{$id_attribute_group}]">
          {foreach from=$group.attributes key=id_attribute item=group_attribute}
            <option value="{$id_attribute}" title="{$group_attribute.name}"{if $group_attribute.selected} selected="selected"{/if}>{$group_attribute.name}</option>
          {/foreach}
        </select>
      {elseif $group.group_type == 'color'}
        <ul id="group_{$id_attribute_group}">
          {foreach from=$group.attributes key=id_attribute item=group_attribute}
            <li class="float-xs-left input-container">
              <label>
                <input class="input-color" type="radio" data-product-attribute="{$id_attribute_group}" name="group[{$id_attribute_group}]" value="{$id_attribute}"{if $group_attribute.selected} checked="checked"{/if}>
                <span
                  {if $group_attribute.html_color_code}class="color" style="background-color: {$group_attribute.html_color_code}" {/if}
                  {if $group_attribute.texture}class="color texture" style="background-image: url({$group_attribute.texture})" {/if}
                ><span class="sr-only">{$group_attribute.name}</span></span>
              </label>
            </li>
          {/foreach}
        </ul>
      {elseif $group.group_type == 'radio'}
        <ul id="group_{$id_attribute_group}">
          {foreach from=$group.attributes key=id_attribute item=group_attribute}
            <li class="input-container float-xs-left">
              <label>
                <input class="input-radio" type="radio" data-product-attribute="{$id_attribute_group}" name="group[{$id_attribute_group}]" value="{$id_attribute}"{if $group_attribute.selected} checked="checked"{/if}>
                <span class="radio-label">{$group_attribute.name}</span>
              </label>
            </li>
          {/foreach}
        </ul>
      {/if}
    </div>
  {/foreach}
</div>

显然，产品页面中的相同代码会调用所有变量，而在我调用主页内容的主页中，我无法恢复它们。我哪里错了？几周前我才开始接触 prestashop，我想我的想法很混乱。我希望我已经清楚了，感谢那些有耐心回答的人。

Answer 1

中使用的变量 $groups 是catalog/_partials/product-variants.tpl从 PoductController.php 传递的，并且仅在产品信息页面上可用。您不能在您的主页或其他地方使用它。如果您想获得相同的结果，您需要在模块中创建一些类似的变量并将其传递给您自己的模板。controller/front/ProductController.php在方法内的文件中创建的变量，assignAttributesGroups但它非常复杂，我认为您可以创建更简单的东西。
