Opencart 在管理面板中添加产品

Question

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，但我的不工作。

我到了视图显示产品表单的地步，但在原始模块中显示了可用的产品，而在我的模块中则没有。

来自管理员的原始代码：

控制器

为什么我无法从可用列表中选择产品？

P.S。抱歉代码示例太长，但我不知道需要什么来解释我的问题。

Answer 1

您在 Controller 文件中遗漏了一行代码，

添加下行

$data['token'] = $this->session->data['token'];

控制器文件 $this->load->model('catalog/product'); 以上

Opencart 在管理面板中添加产品
