获得致命错误：在Open Cart Payment Module中调用未定义的方法Loader :: controller（）？

Question

我只是想将moneybookers支付模块克隆到Open Cart中的支付模块并猜测我现在被困在这里的错误如下：

Fatal error: Call to undefined method Loader::controller() in /home/hunter/public_html/opencart_new/admin/controller/payment/mpower.php on line 213

}

第213行是：

$data['header'] = $this->load->controller('common/header');

我还没有完全开发模块，但差不多完成了付款模块的管理员方面，但是它给出了错误，所以如果有人可以请一看，让我知道我做错了什么？

Answer 1

以下是第213行之后的代码：

替换此代码：

$data['header'] = $this->load->controller('common/header');
$data['column_left'] = $this->load->controller('common/column_left');
$data['footer'] = $this->load->controller('common/footer');

$this->response->setOutput($this->load->view('payment/mpower.tpl', $data));

使用

$this->template = 'payment/mpower.tpl';
    $this->children = array(
        'common/header',
        'common/column_left',
        'common/footer'
    );

    $this->response->setOutput($this->render());

无需为页眉，页脚等调用控制器。

并且无需在$data中传递setOutput，当您在浏览器中加载支付网关链接时，它会自动传入您的视图文件，因为默认情况下它会调用您的索引方法。

我遇到了同样的问题，发现我在opencart版本2.0.X.X中使用了1.5.X.X模块。您可能只是使用了错误的模块版本。
