opencart在搜索结果页面显示每个产品的类别

Question

我使用的是Opencart 2.2.0，我试图在搜索页面上显示每个产品的类别。到目前为止，我有我的控制器是这样的：

<?php

} 

但我不知道如何显示每个产品的类别。有什么建议么？谢谢。

在你的控制器文件，发现：$data['products'][] = array(

它添加之前：

 $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']) 
       ); 
      } 
     } 

它添加后：

  // store categories information 
      'product_categories' => $product_categories, 

你的代码必须是这样的：

  $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) 
      ); 

现在打开你的模板文件：

catalog\view\theme\default\template\product\search.tpl 

发现：

<?php if ($product['rating']) { ?> 

添加之前：

<?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> &nbsp; 
      <?php } ?> 
     </div> 
    <?php } ?>
