Opencart：权限被拒绝错误

Question

我在 Opencart 上制作了一个自定义模块。但是在编辑时显示以下错误：

为此，我也遵循了这些步骤。但仍然出现相同的错误：

   1. Login to admin, go to System > User Group.
   2.  Edit your admin usergroup (probably Top Administrator group).
   3. Add permission to your new extension modules (both Access Permission and Modify Permission).

如果有任何问题，这是我的控制器演示：

<?php
class Controllerextensionmodulehelloworld extends Controller {
    private $error = array(); // This is used to set the errors, if any.

    public function index() {
        // Loading the language file of helloworld
        $this->load->language('extension/module/helloworld'); 

        // Set the title of the page to the heading title in the Language file i.e., Hello World
        $this->document->setTitle($this->language->get('heading_title'));

        // Load the Setting Model  (All of the OpenCart Module & General Settings are saved using this Model )
        $this->load->model('setting/setting');

        // Start If: Validates and check if data is coming by save (POST) method
        if (($this->request->server['REQUEST_METHOD'] == 'POST') && $this->validate()) {
            // Parse all the coming data to Setting Model to save it in database.
            $this->model_setting_setting->editSetting('helloworld', $this->request->post);

Answer 1

找到

$this->response->redirect($this->url->link('extension/module', 'token=' . $this->session->data['token'], 'SSL'));

替换

$this->response->redirect($this->url->link('extension/extension', 'token=' . $this->session->data['token'] . '&type=module', true));

取消按钮

找到

   $data['cancel'] = $this->url->link('extension/module', 'token=' . $this->session->data['token'], 'SSL'); // URL to be redirected when cancel button is pressed

替换为

$data['cancel'] = $this->url->link('extension/extension', 'token=' . $this->session->data['token'] . '&type=module', true);

用于保存按钮操作

找到

 $data['action'] = $this->url->link('extension/module/helloworld', 'token=' . $this->session->data['token'], 'SSL'); // URL to be directed when the save button is pressed

替换

if (!isset($this->request->get['module_id'])) {
        $data['action'] = $this->url->link('extension/module/helloworld', 'token=' . $this->session->data['token'], true);
    } else {
        $data['action'] = $this->url->link('extension/module/helloworld', 'token=' . $this->session->data['token'] . '&module_id=' . $this->request->get['module_id'], true);
    }

转到

system->users->users group->Administrator->edit

这里可以看到访问权限修改权限，请select都在这里&保存就是了。现在您可以访问您的自定义模块了。
