OpenCart调用其他控制器

问题描述

我有一个自定义模块，现在想从checkout/cart调用add()函数.如何调用控制器和函数?

I have a custom module, and now want to call the add() function from checkout/cart. How do I call the controller and function?

我尝试了$this->load->controller('checkout/cart');，但这会返回致命异常.

I have tried $this->load->controller('checkout/cart'); but this returns a fatal exception.

我正在使用OpenCart v 1.5.6.4

推荐答案

在OpenCart 1.5.*中，getChild用于加载其他控制器.具体来说，它正在运行到所需控制器和功能的路由.例如，common/home将从common组/文件夹中加载home控制器.通过添加第三个选项，我们指定了一个函数.在这种情况下，为添加"-checkout/cart/add.

In OpenCart 1.5.*, getChild is used to load other controllers. Specifically, it is running a route to the desired controller and function. For example, common/home would load the home controller from the common group/folder. By adding a third option we specify a function. In this case, 'add' - checkout/cart/add.

class ControllerModuleModule1 extends Controller {
  protected function index() {
    ob_start();
    $this->getChild('checkout/cart/add');
    $this->response->output();
    $response = ob_get_clean();
  }
}

大多数控制器不返回或回显任何内容，而是在$this->response对象中指定要输出的内容.要获取正在渲染的内容，您需要调用$this->response->output();.在上面的代码中，$response是checkout/cart/add回显的json字符串.

Most controllers don't return or echo anything, but specify what to output in the $this->response object. To get what is being rendered you need to call $this->response->output();. In the above code $response is the json string that checkout/cart/add echos.
