php - Passing a parameter in Laravel Form Request -

i have admin able create , update users. made new form request called 'userupdaterequest'. how can pass user id can update user detail? here rules:

// userupdaterequest  public function rules()     {         return [             'firstname' => 'required|min:2|max:255',             'lastname' => 'required|min:2|max:255',             'username' => 'required|max:255',             'password' => 'required|min:6|confirmed',             'email' => 'required|email|max:255|unique:users,email,????',             'contact' => 'required|integer',             'gender' => 'required|in:m,f',             'role_id' => 'required|exists:roles,id',         ];     }  // controller public function update(userupdaterequest $request, user $user)     {         $user->update([             'firstname' => request('firstname'),             'lastname' => request('lastname'),             'username' => request('username'),             'email' => request('email'),             'contact' => request('contact'),             'gender' => request('gender'),             'role_id' => request('role_id'),         ]);          session()->flash('message', 'user has been added.');          return redirect('/users/' . $user->id);     } 

'required|email|max:255|unique:users,email,????', confused.

since admin changing users assume have user data on view file.

you can pass hidden input on form.

<input type="hidden" value="{{$user->id}}" name="user_id" /> 

and receive on controller.

$user_id = $request->input('user_id'); $user = \app\user::find($user_id);  //validation comes here 

edit depending on new information

public function update(userupdaterequest $request, user $user)  

should

public function update(request $request, user $user)  

and have call request on controller;

use illuminate\http\request; 

after can request

dd($request->all()); 

but if using special request post userupdaterequest class.
