我正在使用Opencart 2.2.0，我正在尝试在搜索页面上显示每个产品的类别。到目前为止，我的控制器是这样的：

但我不知道如何显示每种产品的类别。有什么建议？谢谢。
答案 0 :(得分：2)
在您的控制器文件中，找到：$data['products'][] = array(
之前添加：
$product_categories = array();
// get categories of each product, based on product id
$categories = $this->model_catalog_product->getCategories($result['product_id']);
if($categories){
// select each category name and create a link to it
foreach($categories as $category){
$category_info = $this->model_catalog_category->getCategory($category['category_id']);
$product_categories[] = array(
'name' => $category_info['name'],
'href' => $this->url->link('product/category', 'path=' . $category_info['category_id'] )
);
}
}
之后添加：
// store categories information
'product_categories' => $product_categories,
您的代码必须如下：
$product_categories = array();
// get categories of each product, based on product id
$categories = $this->model_catalog_product->getCategories($result['product_id']);
if($categories){
// select each category name and create a link to it
foreach($categories as $category){
$category_info = $this->model_catalog_category->getCategory($category['category_id']);
$product_categories[] = array(
'name' => $category_info['name'],
'href' => $this->url->link('product/category', 'path=' . $category_info['category_id'] )
);
}
}
$data['products'][] = array(
// store categories information
'product_categories' => $product_categories,
'product_id' => $result['product_id'],
'thumb' => $image,
'name' => $result['name'],
'description' => utf8_substr(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8')), 0, $this->config->get($this->config->get('config_theme') . '_product_description_length')) . '..',
'price' => $price,
'special' => $special,
'tax' => $tax,
'minimum' => $result['minimum'] > 0 ? $result['minimum'] : 1,
'rating' => $result['rating'],
'href' => $this->url->link('product/product', 'product_id=' . $result['product_id'] . $url)
);
现在打开模板文件：
catalog\view\theme\default\template\product\search.tpl
查找
<?php if ($product['rating']) { ?>
在它之前添加：
<?php if($product['product_categories']){ ?>
<div class="product-categories">
<?php foreach($product['product_categories'] as $category){ ?>
<a href="<?php echo $category['href']; ?>" title="<?php echo $category['name']; ?>"><?php echo $category['name']; ?></a>
<?php } ?>
</div>
<?php } ?>
