php - Laravel 5 Route::group 与公共(public)变量

Question

我有这样的代码:

Route::group(['prefix'=>'dashboard'],function(){        
    Route::get('addnew',function(){
        $user = DB::table('users')->where('username','=',session('username'))->first();
        $data = array('level' => $user->level, 'name' => $user->name,'email' => $user->email);
        return view('layout.addnew')->with($data);
    });
    Route::get('load',function(){
        $user = DB::table('users')->where('username','=',session('username'))->first();
        $data = array('level' => $user->level, 'name' => $user->name,'email' => $user->email);
        return view('layout.load')->with($data);
    });
});

但是当我像这样使用公共(public)变量时它不起作用:

Route::group(['prefix'=>'dashboard'],function(){

    $user = DB::table('users')->where('username','=',session('username'))->first();
    $data = array('level' => $user->level, 'name' => $user->name,'email' => $user->email);

    Route::get('addnew',function(){        
        return view('layout.addnew')->with($data);
    });
    Route::get('load',function(){        
        return view('layout.load')->with($data);
    });
});

请帮帮我!

当您使用闭包时，您需要明确授予对变量的访问权限，因为它们在函数的上下文之外。您可以使用“使用”功能执行此操作。

Route::group(['prefix'=>'dashboard'],function(){

    $user = DB::table('users')->where('username','=',session('username'))->first();
    $data = array('level' => $user->level, 'name' => $user->name,'email' => $user->email);

    Route::get('addnew',function() use($data) {        
        return view('layout.addnew')->with($data);
    });
    Route::get('load',function() use($data) {        
        return view('layout.load')->with($data);
    });
});
