'I want to show a specific message when the user fail to login for username and password separately in laravel 5

I am using laravel login api.

I want to show a message for users who fail to login whether it's the username that is not correct or the password the right way.

I looked at AuthenticatesUsers.php there is a method that is responsible for returning a failed login message called sendFailedLoginResponse I edited it so it can do what I want and that's my code.

protected function sendFailedLoginResponse(Request $request)
{

    $inputemail = $request->input('email');
    $user = User::where('email', $inputemail)->first();

    if($user == '') {
        throw ValidationException::withMessages([

            $this->username() => [trans('auth.usernameWrong')],
        ]);
    } else {
        throw ValidationException::withMessages([
            'password' => [trans('auth.passwordWrong')],
        ]);
    }
}

I know that there is a better way than this becasue I doubly checked the username the first one was laravel check and the second is my query check.

I am new to laravel and I want to know how it can be done the right way.

Try this

protected function sendFailedLoginResponse(Request $request)
{

       // Load user from database
      $user = \App\User::where($this->username(), $request->{$this->username()})->first();

     if(!Hash::check($request->password, $user->password) {
           throw ValidationException::withMessages([

          $this->username() => [trans('auth.passwordWrong')],
       ]);
     } elseif($!user->exists){
         throw ValidationException::withMessages([
           'password' => [trans('auth.usernameWrong')],
      ]);
    }
}

Use Hash::check() method to check the password

This should help

Go to vendor\laravel\ui\auth-backend\AuthenticatesUsers.php and edit the existing function sendFailedLoginResponse(Request $request)

protected function sendFailedLoginResponse(Request $request)
    {
        $user = User::where($this->username(), $request->{$this->username()})->first();
        if($user && !Hash::check($request->password, $user->password) ){
            throw ValidationException::withMessages([
                'password' => [trans('auth.password')],
            ]);
        }else{
            throw ValidationException::withMessages([
            $this->username() => [trans('auth.email')],
        ]);
        }
    }

Don't forget to include:

use App\Models\User;
use Illuminate\Support\Facades\Hash;

Make sure the above codes are placed inside the vendor\laravel\ui\auth-backend\AuthenticatesUsers.php

Now you can navigate to resources\lang\en\auth.php and include in the code below:

'email' => 'The provided email is incorrect.',
'password' => 'The provided password is incorrect.',

Solution 3:[3]

You can check the password with Hash::check() method:

$user = User::where('email', $request->email)->first();

if (is_null($user)) {
    // There is no user
} elseif (!Hash::check($request->password, $user->password) {
    // Password is wrong
}
