Opencart 在类别页面中获取 category_id [英] Opencart get category_id in category page

问题描述

试图在类别页面中获取新"标签.例如，如果产品的类别为 219，则它会有贴纸.

Trying to get "new" sticker in category page. For example if product have category 219 it would have sticker.

我在控制器 category.php 中添加的内容

What I have added in controller category.php

$product_info = $this->model_catalog_product->getProduct($product_id);

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

$categories_info = $this->model_catalog_category->getCategory($categories[0]['category_id']);

$this->data['category_id'] = $categories_info['category_id'];

在 category.tpl 中

In category.tpl

<?php if($category_id=="219") { ?>
<img src="new.jpg">
<?php } ?>

但是什么都没有出现.

UPD:更改代码

$categories = $this->model_catalog_product->getCategories($result['product_id']);

    $categories_info = $this->model_catalog_category->getCategory($categories[3]['category_id']);

    $this->data['category_id'] = $categories_info['category_id'];

category.tpl

category.tpl

  <?php if ($category_id=="219") { ?>                           

            <?php } else {  ?>

            <?php } ?>

仅当我使用 $categories[3]['category_id'] 时才有效，但我无法使用 php 函数 in_array 搜索数组值.

It works only if i use $categories[3]['category_id'] but I can't search value it array with php function in_array.

推荐答案

如果你想为模板发送一些数据，你必须使用 $data 数组.

If you want send some data for template you have to use $data array.

例如:

$data['category_id'] = $categories_info['category_id'];

然后使用 $category_id
