Prestashop 1.7 模板不传递变量
Prestashop 1.7 template not pass variable
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=$product_pack}
{/block}
{/foreach}
</section>
{/if}
{/block}
{block name='product_discounts'}
{include file='catalog/_partials/product-discounts.tpl'}
{/block}
{block name='product_add_to_cart'}
{include file='catalog/_partials/product-add-to-cart.tpl'}
{/block}
{block name='product_additional_info'}
{include file='catalog/_partials/product-additional-info.tpl'}
{/block}
{block name='product_refresh'}
<input class="product-refresh ps-hidden-by-js" name="refresh" type="submit" value="{l s='Refresh' d='Shop.Theme.Actions'}">
{/block}
</form>
{/block}
</div>
一切正常。
我最感兴趣的是此块中引用的代码部分
{block name='product_variants'}
{include file='catalog/_partials/product-variants.tpl'}
{/block}
密码是：
<div class="product-variants">
{foreach from=$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">

<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 和主文件 "ps_featuredproducts.tpl" 的 tpl 文件，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，但是变体的所有值都不让我看到它们，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">

<span
{if $group_attribute.html_color_code}class="color" style="background-color: {$group_attribute.html_color_code}" {/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？几周前我才接触到 prestashop，我想我的想法很混乱。
希望我已经说清楚了，感谢有耐心回答的人。
catalog/_partials/product-variants.tpl 中使用的变量 $groups 是从 PoductController.php 传递过来的，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。如果你想获得相同的结果，你需要在你的模块中创建一些类似的变量并将它传递给你自己的模板。在方法 assignAttributesGroups 中的文件 controller/front/ProductController.php 中创建的变量，但它非常复杂，我认为您可以创建更简单的东西。
ps_featuredproducts 中不存在变量 $groups。如果你想在主页上使用它，你必须将它添加到模块中。
为此，您必须像这样修改 ps_featuredproducts.php 中的函数 getWidgetVariables()。
public function getWidgetVariables($hookName = null, array $configuration = [])
{
$products = $this->getProducts();
foreach ($products as &$product) {
$product_object = new Product((int)$product['id_product']);
$groups = array();
$attributes_groups = $product_object->getAttributesGroups($this->context->language->id);
if (is_array($attributes_groups) && $attributes_groups) {
foreach ($attributes_groups as $k => $row) {
if (!isset($groups[$row['id_attribute_group']])) {
$groups[$row['id_attribute_group']] = array(
'group_name' => $row['group_name'],
'name' => $row['public_group_name'],
'group_type' => $row['group_type'],
'default' => -1,
);
}
$groups[$row['id_attribute_group']]['attributes'][$row['id_attribute']] = array(
'name' => $row['attribute_name'],
'html_color_code' => $row['attribute_color'],
'texture' => (@filemtime(_PS_COL_IMG_DIR_.$row['id_attribute'].'.jpg')) ? _THEME_COL_DIR_.$row['id_attribute'].'.jpg' : '',
'selected' => (isset($product_for_template['attributes'][$row['id_attribute_group']]['id_attribute']) && $product_for_template['attributes'][$row['id_attribute_group']]['id_attribute'] == $row['id_attribute']) ? true : false,
);
if ($row['default_on'] && $groups[$row['id_attribute_group']]['default'] == -1) {
$groups[$row['id_attribute_group']]['default'] = (int) $row['id_attribute'];
}
if (!isset($groups[$row['id_attribute_group']]['attributes_quantity'][$row['id_attribute']])) {
$groups[$row['id_attribute_group']]['attributes_quantity'][$row['id_attribute']] = 0;
}
$groups[$row['id_attribute_group']]['attributes_quantity'][$row['id_attribute']] += (int) $row['quantity'];
}
// wash attributes list (if some attributes are unavailables and if allowed to wash it)
if (!Product::isAvailableWhenOutOfStock($product_object->out_of_stock) && Configuration::get('PS_DISP_UNAVAILABLE_ATTR') == 0) {
foreach ($groups as &$group) {
foreach ($group['attributes_quantity'] as $key => &$quantity) {
if ($quantity <= 0) {
unset($group['attributes'][$key]);
}
}
}
}
}
$product['groups'] = $groups;
}
if (!empty($products)) {
return array(
'products' => $products,
'allProductsLink' => Context::getContext()->link->getCategoryLink($this->getConfigFieldsValues()['HOME_FEATURED_CAT']),
);
}
return false;
}
我在这里使用函数 ProductController::assignAttributesGroups() 中的部分代码来仅获取 $groups 变量。
最后，在ps_featuredproducts.tpl中，你必须替换：
<div class="product-variants">
{foreach from=$groups key=id_attribute_group item=group}
<div class="clearfix product-variants-item">
作者：
<div class="product-variants">
{foreach from=$product.groups key=id_attribute_group item=group}
<div class="clearfix product-variants-item">
然后，所有变量将显示在产品页面上。
