opencart-在子类别页面上获取父类别名称/ID [英] opencart - get parent category name/id on a sub-category page

问题描述

我有一个代码块，只想对特定类别的子类别执行.我想为此使用面包屑，但是如果为当前子类别设置了SEO网址，则父类别将从面包屑中消失.

I have a code block that I want to execute only on sub-categories of a particular category. I wanted to use breadcrumbs for this purpose but the parent category disappears from breadcrumbs if a SEO url is set for the current sub-category.

有没有办法在子类别中获取父类别的名称或ID?

Is there a way to get the name or id of the parent category inside a sub-category?

推荐答案

每个类别都分配了一个parent_id.您需要根据当前类别获取parent_id.

Every category has a parent_id assigned to it. You need to get the parent_id based off the current category.

$result = $this->db->query("SELECT `parent_id` FROM `" . DB_PREFIX . "category` WHERE `category_id` = '123'");
$parent_id = $result->row['parent_id'];
