Php Opencart-显示两种产品之一'；s类

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”

$product_info['name'].-'$类别信息[“名称”]

问题是当一些产品属于两个或更多类别时。如何告诉OpenCart使用任何一种产品类别？我真的不在乎哪一个：）

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

        $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));

在

/catalog/controller/product/product.php

$this->document->setTitle($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));

，这取决于您选择类别信息的方式）。请发布您的代码这实际上取决于您选择类别信息的方式。发布你的代码，非常感谢。很好！非常感谢你。很好！
