在opencart中按类别ID获取类别产品

Question

您好我想自定义功能模块，通过管理员显示类别而不是特色模块

当我选择类别时它会显示类别产品什么是控制器的代码，它将类别n赋予产品数组到该类别

下面是类别选择输入的视图代码

        <td><select name="category_id">

        <?php foreach($categories as $category) { ?>
        <option value="<?php echo $category['category_id'];?>"><?php echo $category['name'];?></option>
         <?php } ?>

        </select>

Answer 1

$categories = $this->model_catalog_product->getProductCategories(
    $this->request->get['product_id']);
foreach($categories as $category_id) {
   // do something
}

将getProductCategories功能添加到model/catalog/product.php

public function getProductCategories($product_id) {
    $product_category_data = array();
    $query = $this->db->query("SELECT * FROM " . DB_PREFIX .
           "product_to_category WHERE product_id = '" . (int)$product_id . "'");
    foreach ($query->rows as $result) {
            $product_category_data[] = $result['category_id'];
    }
    return $product_category_data;
}
