Angularjs & PHP Login

Question

I'm new to angularjs, I'm bit confused about Login Process.

Everytime I log in I'm redirected to the specific page. Which is set already in the code.

I just want to check if the user is logged in. If yes then redirect to --Home-- if not logged in redirect to --Login Again--

What should I use for this?

I heard about local storage. SessionStorage, I'm not familiar with them. Tell me which way I can manage Login?

Here is my controller for Login

app.controller('AngularLoginController', ['$scope', '$http', function($scope, $http) {   
    $scope.loginForm = function() {         
            $http.post("login.php", {
            'email' :$scope.inputData.email,
            'password':$scope.inputData.password
            }).success(function(data) {
                console.log(data);                  
                if ( data == 'correct') {
                window.location.href = 'welcome_dashboard.php';
                } 
            else {
                $scope.errorMsg = "Invalid Email and Password";
            }
        })
        }
}]);

You can use $cookieStore of angular js

after successfull login you can put login true

$cookieStore.put('login', true);

and check in your dashboard controller if $cookieStore.get('login') undefined than redirect on login page

When you logout you need to remove this cookie $cookieStore.remove('login')

if you user routerprovider than use resolve it's easy to check login or not here one simple example of resolve

function ($routeProvider) {
    $routeProvider.
        when('/', {
            controller: 'dashboardController',
            templateUrl: 'app/views/dashboard.html',
            resolve:{loggedIn:onlyLoggedIn}
         })
 }

var onlyLoggedIn = function ($location,$q,$cookieStore,$rootScope) {
    var deferred = $q.defer();
    if (typeof ($cookieStore.get("login")) === "undefined") {
        deferred.reject();
        window.location.href = 'login.html';
    }else{
        $rootScope.display = true;
        deferred.resolve();
    }
    return deferred.promise;

};
