This tutorial is the continuation from User account sign-in II - Validation.

Now we have validated user inputs: email and password. In this chapter, we want to authenticate user's login attempt.

In order to get useful debug information, we should add a 'debug' => true to app/config/app.php

In this section, we'll use Auth::attempt() to handle the validated user's login attempt. The Auth::attempt() is to authenticate a user using the given credentials.

AccountController.php file:

class AccountController extends BaseController {
        ...
	/* After submitting the sign-in form */
	public function postSignIn() {
		$validator = Validator::make(Input::all(),
			array(
				'email' 	=> 'required|email',
				'password'	=> 'required'
			)
		);
		if($validator->fails()) {
			// Redirect to the sign in page
			return Redirect::route('account-sign-in')
				->withErrors($validator)
				->withInput();   // redirect the input
		} else {
			$auth = Auth::attempt(array(
				'email' => Input::get('email'),
				'password' => Input::get('password'),
				'active' => 1
			));
		}

		if($auth) {
			// Redirect to the intented page
			// For example, a user will be redirected to '/
			// when the user tried to change password without login'
			return Redirect::intended('/');
		} else {
			return Redirect::route('account-sign-in')
			->with('global', 'Wrong Email/password wrong.');
		}

		return Redirect::route('account-sign-in')
			->with('global', 'There is a problem. Have you activated your account?');
	}
        ...

If the user typed in wrong password with correct Email:

Successful login attempt:

home.blade.php file:

Here we want to say to Hello when a user logged in successfully.

@extends('layout.main')

@section('content')
	@if(Auth::check())
		
Hello, {{ Auth::user()->username }}.
	@else
		
Sorry, not signed in.
	@endif
@stop
