在 Opencart 4 中创建管理菜单

Question

在 Opencart4 中我正在创建一个新模块。安装模块并通过访问正常工作

Admin-> extensions -> modules -> module name -> (then edit)

。

现在我想在管理部分的“目录”菜单下添加一个新的菜单项。

我已经做了以下事情

在模块的控制器中我添加了

$this->load->model('setting/event');
$this->model_setting_event->deleteEventByCode('MY_EVENT');
$this->model_setting_event->addEvent('MY_EVENT', "",'admin/view/common/column_left/before', 'extension/testimonials/module/testimonials/ADDTOADMINMENU');

ADDTOADMINMENU

模块控制器中的功能如下

public function ADDTOADMINMENU(&$route, &$data){

        /**
        * Check if current logged in user has permission to access that link
        * Replace "extension/module/MY_EXTENSION" with your target path
        * This check can very well be ignored/deleted...
        **/
    echo "Here";
    exit;
        if ($this->user->hasPermission('access', 'extension/testimonials/module/testimonials')) {
            $my_menu_entry = array(
                'id'       => 'menu-MY_EXTENSION',
                'icon'     => 'fa-check',
                'name'     => 'My menu entry',
                'href'     => $this->url->link('extension/testimonials/module/testimonials', 'user_token=' . $this->session->data['user_token'], true),
                'children' => array()
            );
    
            $target_menu_id      = 'menu-catalog';
            $target_submenu_href = $this->url->link('catalog/product', 'user_token=' . $this->session->data['user_token'], true);
    
            $new_menu = array();
    
            foreach( $data['menus'] as &$menu ) {
    
                if( $menu['id'] == $target_menu_id ) {
    
                    $new_submenu = array();
    
                    foreach( $menu['children'] as $submenu ) {
                        if( $submenu['href'] == $target_submenu_href ) {
                            $new_submenu[] = $my_menu_entry;
                            $new_submenu[] = $submenu;
                        } else {
                            $new_submenu[] = $submenu;
                        }
                    }
                    $menu['children'] = $new_submenu;
                    $new_menu[] = $menu;
                } else {
                    $new_menu[] = $menu;
                }
            }
    
            $data['menus'] = $new_menu;
        }
    }

但连这个功能都没有进入。我遵循的方法正确吗？

请指导。

Answer 1

试试这个：

$this->model_setting_event->addEvent('MY_EVENT', "",'admin/view/common/column_left/before', 'extension/testimonials/module/testimonials/ADDTOADMINMENU');

替换为：

$this->model_setting_event->addEvent('MY_EVENT', "",'admin/view/common/column_left/before', 'extension/testimonials/module/testimonials|ADDTOADMINMENU');

我还没有检查过，但是 OC 稍微改变了他们的框架。

解决方案：

更换

$this->model_setting_event->addEvent('MY_EVENT', "",'admin/view/common/column_left/before', 'extension/testimonials/module/testimonials/ADDTOADMINMENU');

与

    $dataEvent = [
            'code' => 'MY_EVENT',
            'description' => '',
            'trigger' => 'admin/view/common/column_left/before',
            'action' => 'extension/testimonials/module/testimonials|ADDTOADMINMENU',
            'status' => true,
            'sort_order' => 0,
        ];

    if (version_compare(VERSION, '4.0.1.0', '>=')) {
        $this->model_setting_event->addEvent($dataEvent);
    } elseif (version_compare(VERSION, '4.0.0.0', '>=')) { 
        $this->model_setting_event->addEvent($dataEvent['code'], $dataEvent['description'], $dataEvent['trigger'], $dataEvent['action'], $dataEvent['status'], $dataEvent['sort_order']);
    }else {

        /* compatibility Opencart 3 */
        $dataEvent['trigger']=str_replace("|","/",$dataEvent['trigger']);

        $this->model_setting_event->addEvent($dataEvent['code'], $dataEvent['trigger'], $dataEvent['action'], $dataEvent['status'], $dataEvent['sort_order']);
    }

现在您可以使用您的代码来更新 Opencart 3 上的管理菜单

Answer 3

并非所有菜单/子菜单项都会有 ID。最好使用菜单文本来标识菜单的放置位置。有时您可能想将菜单放置在子菜单的深处。这是使用 array_splice 的更高效的代码。

public function ADDTOADMINMENU(&$route, &$data){
  /**
* Check if current logged in user has permission to access that link
* Replace "extension/module/MY_EXTENSION" with your target path
* This check can very well be ignored/deleted...
**/

if ($this->user->hasPermission('access', 'extension/MY_EXTENSION/module/MY_EXTENSION')) {
    $newMenuItem = array(
        'name'     => 'My menu entry',
        'href'     => $this->url->link('extension/MY_EXTENSION/module/MY_EXTENSION', 'user_token=' . $this->session->data['user_token'], true),
        'children' => array()
    );

    // Iterate through the top-level menus
    foreach ($data['menus'] as &$menu) {
        if (isset($menu['name']) && $menu['name'] === 'Top Level Menu') {
            // Iterate through 'Top Level Menu' menu's children to find 'Sub Menu'
            foreach ($menu['children'] as &$subMenu) {
                if (isset($subMenu['name']) && $subMenu['name'] === 'Sub Menu') {
                    // Iterate through 'Sub Menu' menu's children to find 'Child Menu'
                    foreach ($subMenu['children'] as $key => $child) {
                        if (isset($child['name']) && $child['name'] === 'Child Menu') {
                            // Insert new item before 'Child Menu'
                            array_splice($subMenu['children'], $key, 0, [$newMenuItem]);
                            return; // Exit function after inserting
                        }
                    }
                }
            }
        }
    }
}

}
