Call to a member function has() on string in laravel - laravel

Question

I am working on user authentication. When a user provides invalid email or password, I want to redirect him to login.blade.php with a flash error message.
// Auth/LoginController:
public function login(Request $request)
{
$user=User::where('email',$request->email)->first();
if(!is_null($user))
{
if($user->status==1)
{
if(Auth::guard('web')->attempt(['email'=>$request->email,'password'=>$request->password],$request->remember))
return redirect()->intended(route('index'));
}
}
else
{
if(Auth::guard('web')->attempt(['email'=>$request->email,'password'=>$request->password],$request->remember))
{
if(Auth::check())
{
Auth::logout();
}
$user->notify(new VerifyRegistration($user));
session()->flash('success','A new confirmation mail has sent to you...Please check and confirm your email');
return redirect('/');
}
else
{
session()->flash('errors','Password is incorrect!!');
return redirect()->route('login');
}
}
}
else
{
session()->flash('errors','Email or Password is incorrect!!');
return redirect('/login');
}
}
I am using the default laravel login.blade.php.

When user enter's wrong password rather than setting up session flash message please use below given code to redirect user in else condition.
return redirect()->route('login')->with('error','Invalid password.');
On login template you can display errors like
#if (session('success'))
<div class="alert alert-success">
<p>{{ session('success') }}</p>
</div>
#endif
#if (session('warning'))
<div class="alert alert-warning">
<p>{{ session('warning') }}</p>
</div>
#endif
#if (session('error'))
<div class="alert alert-error">
<p>{{ session('error') }}</p>
</div>
#endif
