在Laravel控制器中缺少參數2

Question

我正在嘗試登錄一個用戶，並將他們帶到顯示基於一個slu content的內容的頁面。

我得到這個錯誤：

ErrorException in ApplicantLoginController.php line 21: 
Missing argument 2 for App\Http\Controllers\Auth\ApplicantLoginController::Login() 

這是我的控制器：

public function Login(Request $request, $slug){ 
     //Validate the form 
     $this->validate($request, [ 
      'email' => 'required', 
      'password' => 'required', 
      'agree' => 'required' 
     ]); 

     //Attempt to log the user in 
     if (Auth::guard('applicant')->attempt(['email' => $request->email,'password' => $request->password])) { 

     $house = House::where('slug', '=', $slug)->first(); 
     return view('client.index')->withHouse($house); 
     } 

     return redirect()->back()->withInput($request->only('email')); 
    } 

這是該頁面的路線，我登錄後帶他們到：

Route::get('client/index/{slug}', ['as' => 'client.index', 'uses' => 'ClientRegistrationController@index']); 

這是我的登錄路線：

Route::get('client/login', 'Auth\ApplicantLoginController@ShowLoginForm')->name('client.login'); 
Route::post('/client/login', 'Auth\ApplicantLoginController@Login')->name('client.login.submit'); 

有關如何解決此問題的任何想法？

這是將用戶的頁面與基於塞

<a href="{{ url('client/index/'.$house->slug) }}" class="btn btn-success btn btn-block">Book now</a> 

內容。如果用戶沒有在頁面登錄按鈕重定向到該登錄頁面：

<form class="form-horizontal" role="form" method="POST" action="{{ route('client.login.submit') }}"> 
        <input name="_token" type="hidden" value="{{ csrf_token()}}"/> 
         <div class="form-group"> 
          <label for="email" class="col-md-3 control-label"></label> 
          <div class="col-md-6"> 
           <input type="email" class="form-control" placeholder="Your Email" name="email" required=""> 
          </div> 
         </div> 

         <div class="form-group"> 
          <label for="password" class="col-md-3 control-label"></label> 
          <div class="col-md-6"> 
           <input type="password" class="form-control" placeholder="Password" name="password" required=""> 
          </div> 
         </div> 

         <div class="form-group"> 
          <div class="col-md-6 col-md-offset-3"> 
           <div class="checkbox"> 
            <label> 
             <input type="checkbox" name="remember"> Remember Me 
            </label> 
           </div> 
          </div> 
         </div> 

         <div class="form-group"> 
          <div class="col-md-6 col-md-offset-3"> 
           <div class="checkbox"> 
            <label> 
             <input type="checkbox" name="agree" required=""> I have read and accepted the <a href="" data-toggle="modal" data-target="#myModal" class="checkbox-terms-client">terms and condition</a> 
            </label> 
           </div> 
          </div> 
         </div> 

         <div class="form-group"> 
          <div class="col-md-8 col-md-offset-3"> 
           <input type="submit" value="Login" class="btn btn-primary"> 

           </input> 

           <a class="btn btn-link" href="#"> 
            Forgot Your Password? 
           </a> 
          </div> 
         </div> 

        </form> 

Answer 1

您應該在郵寄路線中聲明$ slug：

Route::post('/client/login/{slug}', 'Auth\ApplicantLoginController@Login')->name('client.login.submit'); 

並且更改表單以添加標準ameter：

<form class="form-horizontal" role="form" method="POST" action="{{ route('client.login.submit', ['slug' => $slug]) }}">
