打开购物车 - 显示两个产品的类别之一


Opencart - display one of two product's category

我有Opencart 1.5.1.3,并修改了元标题以显示"产品名称 - 产品类别"

$product_info['name'] .' - ' .$category_info['name']

问题是当某些产品属于两个或多个类别时。如何告诉打开购物车使用任何一个产品类别?我真的不在乎哪一个:)

$this->language->load('product/product');
    $this->data['breadcrumbs'] = array();
    $this->data['breadcrumbs'][] = array(
        'text'      => $this->language->get('text_home'),
        'href'      => $this->url->link('common/home'),         
        'separator' => false
    );
    $this->load->model('catalog/category'); 
    $this->request->get['path'] = (isset($this->request->get['path']))? $this->request->get['path'] : $this->model_catalog_category->getCategoryPath($this->request->get['product_id']);
    if (isset($this->request->get['path'])) {
        $path = '';
        foreach (explode('_', $this->request->get['path']) as $path_id) {
            if (!$path) {
                $path = $path_id;
            } else {
                $path .= '_' . $path_id;
            }
            $category_info = $this->model_catalog_category->getCategory($path_id);
            if ($category_info) {
                $this->data['breadcrumbs'][] = array(
                    'text'      => $category_info['name'],
                    'href'      => $this->url->link('product/category', 'path=' . $path),
                    'separator' => $this->language->get('text_separator')
                );
            }
        }
    }

您上面的代码假设您通过类别访问产品,而实际上这并不总是发生。相反,您希望执行以下操作

/catalog/controller/product/product.php中找到此行

$this->document->setTitle($product_info['name']);

将其替换为以下内容

        $result = $this->db->query("
            SELECT `cd`.`name`
            FROM `" . DB_PREFIX . "product_to_category` `p2c`
            LEFT JOIN `" . DB_PREFIX . "category_description` `cd`
            ON `cd`.`category_id` = `p2c`.`category_id`
            WHERE `p2c`.`product_id` = '" . (int) $product_id . "'
            AND `cd`.`language_id` = '" . $this->confing->get('config_language_id') . "'
            ORDER BY `cd`.`category_id` DESC
            LIMIT 1
        ");
        $category_name = $result->num_rows ?  $result->row['name']: '';
        $this->document->setTitle($product_info['name'] . (empty($category_name) ? '' : ' - ' . $category_name));

这将始终显示作为分配给产品的类别创建的最后一个类别。如果未分配类别,它也不会显示类别(并隐藏 -)
