}

但我不知道如何显示每种产品的类别。有什么建议?谢谢。

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