Opencart在管理面板中添加产品
我正在为opencart 2.2.0.0开发一个模块，我复制了一些基本功能但是我的工作还没有。
我到了视图显示产品形式的位置，但在原始模块中显示了可用的产品，并且我的模块不显示。
管理员的原始代码：
控制器

为什么我无法从可用列表中选择产品？
P.S。对于长代码示例感到抱歉，但我不知道解释我的问题需要什么。
1 个答案:
答案 0 :(得分：1)
您错过了控制器文件中的一行代码，
添加以下行
$data['token'] = $this->session->data['token'];
控制器文件中的$this->load->model('catalog/product');以上
