$errors variable not available in controller and blade

@MohamedTammam I tried filling up the form with a validation error but still its not showing up

@Chimpoo How are you validating? can you please show the code both the view file and the controller.

@MohamedTammam In Controller public function emplogin(request $req){

     $validate = $req->validate([
        'email' => 'required',
      'password' => 'required|min:5',
         ]);
        return $req->input();

}

in Blade file

@foreach ($errors->all() as $error)
• {{ $error }}
@endforeach

        <!-- Email input -->
        <div class="form-outline mb-4">
          <input type="email" id="form3Example3" class="form-control form-control-lg"
            placeholder="Enter a valid email address" name="email" />
          <label class="form-label" for="form3Example3">Email address</label>
        </div>

        <!-- Password input -->
        <div class="form-outline mb-3">
          <input type="password" id="form3Example4" class="form-control form-control-lg"
            placeholder="Enter password" name="password" />
    //      ..... more code below

@Chimpoo Where is the form tag?

@MohamedTammam Also I tried making a new project with the same code but in that new project in he kernel.php file I dont have \Illuminate\Session\Middleware\StartSession::class, in the global HTTP middleware stack. so I commented out this line in my original project having this errors and erros starts showing up but I have adminlogin code also on this project. After commentng out this line, that login page is now giving errors ike "Session store not set on request."

@Chimpoo Did you run composer install?

@MohamedTammam Its there Heres te whole code

    <div class="col-md-8 col-lg-6 col-xl-4 offset-xl-1">
      <form action="" method="post">
          @csrf  
          @if($errors->any())
          <div>
            <ul>
                @foreach ($errors->all() as $error)
                    <li>{{ $error }}</li>
                @endforeach
            </ul>
        </div>
        @endif
    
        <!-- Email input -->
        <div class="form-outline mb-4">
          <input type="email" id="form3Example3" class="form-control form-control-lg"
            placeholder="Enter a valid email address" name="email" />
          <label class="form-label" for="form3Example3">Email address</label>
        </div>

        <!-- Password input -->
        <div class="form-outline mb-3">
          <input type="password" id="form3Example4" class="form-control form-control-lg"
            placeholder="Enter password" name="password" />
          
          <label class="form-label" for="form3Example4">Password</label>
        </div>
        {{-- <div>
          @error('password')
          <span>{{$message}}</span>
       @enderror
        </div> --}}

        <div class="d-flex justify-content-between align-items-center">
          <!-- Checkbox -->
        
          <a href="#!" class="text-body">Forgot password?</a>
        </div>

        <div class="text-center text-lg-start mt-4 pt-2">
          <button type="submit" class="btn btn-primary btn-lg"
            style="padding-left: 2.5rem; padding-right: 2.5rem;">Login</button>
          <p class="small fw-bold mt-2 pt-1 mb-0">Don't have an account? <a href="{{route('reg')}}"
              class="link-danger">Register</a></p>
        </div>

      </form>
    </div>

  </div>
</div>

@Chimpoo The action attribute in the form is empty, you need to add the correct URL to that.

@MohamedTammam I am using the home page with routes like

Route::get('/', [Emp_Controller::class,'emp_welcome']);

Route::post('/', [Emp_Controller::class,'emplogin']);

and in the controller

public function emp_welcome(){ return view('emp_login'); }

public function emplogin(request $req){
    
     $validate = $req->validate([
        'email' => 'required',
      'password' => 'required|min:5',
         ]);
        return $req->input();

}

@MohamedTammam Thankyou for the help. Appreciate it

@Chimpoo NO, THAT IS NOT FINE.

You have the keep that middlewares for security reasons.

@MohamedTammam the one I commented out(\Illuminate\Session\Middleware\StartSession::class) is already there in gobal midleware list also which runs on every request. Is it still fine or not?

@Chimpoo Don't remove anything that comes with the default installation.
