Laravel 5 – How to check username & password is match with table?

I have created the below login form in Laravel 5 and I want to simply check if the username & password matches with that of the database table and if so, redirect to the dashboard page else stay on the login page. I am also trying to find the solution by myself but I am posting this question to get an idea of how to do these things in Laravel 5.

Any idea??

try like this

login.blade.php

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css">
</head>
<body>
<div class="container">
<h3>Login Form</h3>  

{!! Form::open(array('url' => 'login', 'method' => 'post')) !!}
<div class="form-group">
    {!! Form::label('UserName') !!}
    {!! Form::text('username', null,
        array(
              'class'=>'form-control',
              'placeholder'=>'Your UserName')) !!}
</div> 
<div class="form-group">
    {!! Form::label('password') !!}
    {!! Form::text('password', null,
        array(
              'class'=>'form-control',
              'placeholder'=>'Your Password')) !!}
</div>

<div class="form-group">
    {!! Form::submit('Login',
      array('class'=>'btn btn-primary')) !!}
</div>
{!! Form::close() !!}

</div>
</body>
</html>

Model:-

<?php namespace App;

use IlluminateAuthAuthenticatable;
use IlluminateDatabaseEloquentModel;
use IlluminateAuthPasswordsCanResetPassword;
use IlluminateContractsAuthAuthenticatable as AuthenticatableContract;
use IlluminateContractsAuthCanResetPassword as CanResetPasswordContract;

class UserRegisters extends Model implements AuthenticatableContract, CanResetPasswordContract { 
    use Authenticatable, CanResetPassword;
    protected $table = 'userregisters';
    protected $fillable = ['user_name', 'password'];
}
?>

Controller:-

<?php namespace AppHttpControllers;
use Input;
use AppHttpRequests;
use AppUser;
use AppUserRegisters;
use AppUserProfiles;
use Validator;
use View;
use Auth;
use AppHttpControllersRedirect;
use Session;
use Hash;
use DB;

class UserRegisterController extends Controller
{
    /**
     * Login a Registered Users.
     *
     */
    public function login(){
        $uname = Input::get('username');
        $password = Input::get('password');
            if (Auth::attempt(array('user_name' => $uname, 'password' => $password))){
            return "success";
            }
            else {        
                return "Wrong Credentials";
            }
        }
    }
}   

route:-

Route::post('/login', 'UserRegisterController@login');

migration:-

<?php

use IlluminateDatabaseSchemaBlueprint;
use IlluminateDatabaseMigrationsMigration;

class Userregisters extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('userregisters', function($table)
        {
            $table->increments('id');
            $table->string('first_name', 128);
            $table->string('last_name', 128);
            $table->string('user_name', 128);
            $table->string('password', 128);
            $table->string('email', 128);
            $table->timestamps();
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::drop('userregisters');
    }
}

let me know if there any errors.
