替换此代码

$data['products'][] = array(
                    '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, $this->config->get('config_product_description_length')) . '..',
                    'description' => html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8'),
                    '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)
                );

通过此代码。

$cats = $this->model_catalog_product->getCategories($product_info['product_id']);

$sep = '';
$catnames = '';

foreach ($cats as $cat){

    $catarr = $this->model_catalog_category->getCategory($cat['category_id']);

    $catnames .= $sep.$catarr['name'];
    $sep = ', ';
}

$data['products'][] = array(
                    '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, $this->config->get('config_product_description_length')) . '..',
                    'description' => html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8'),
                    'price'       => $price,
                    'special'     => $special,
                    'tax'         => $tax,
                    'minimum'     => $result['minimum'] > 0 ? $result['minimum'] : 1,
                    'rating'      => $result['rating'],
                    'category'    => $catnames,
                    'href'        => $this->url->link('product/product', 'product_id=' . $result['product_id'] . $url)
                );

并且在模板文件中，您可以使用 $product['category'] 在循环中简单地调用它。
