Wraps the UserApp PHP client into a small and user-friendly API.

Getting started

Finding your App Id

If you don't have a UserApp account, you need to create one.

• App Id: The App Id identifies your app. After you have logged in, you should see your App Id instantly. If you're having trouble finding it, follow this guide.

Loading the library

UserApp relies on the autoloading features of PHP to load its files when needed. The autoloading complies with the PSR-0 standard which makes it compatible with most of the major frameworks and libraries. Autoloading in your application is handled automatically when managing the dependencies with Composer.

Using Composer? Add this to your composer.json

{
	"require": {
		"userapp/widget": "~0.6.3"
	}
}

Not using Composer? Use the library's own autoloader

require 'autoload.php';

Example

bootstrap.php

<?php

use \UserApp\Widget\User;

// Import composer autoloader
require_once('vendor/autoload.php');

User::setAppId("YOUR APP ID");

must_authenticate.php

<?php

use \UserApp\Widget\User;

require_once('bootstrap.php');

User::onUnauthorized(function ($sender, $call_context, $error){
    header('Location: /login.php');
    die();
});

login.php

<?php

use \UserApp\Widget\User;

require_once('bootstrap.php');

if($_SERVER['REQUEST_METHOD'] === 'POST'){
    $redirect_to = 'login.php?error=INVALID_CREDENTIALS';

    if(User::login($_POST['username'], $_POST['password'])){
        $redirect_to = 'user/profile.php';
    }

    header('Location: /' . $redirect_to);
    die();
}

?>

<form method="post">
    Username: <input type="text" name="username" /><br />
    Password: <input type="password" name="password" /><br />
	
	<? if(isset($_GET['error']) && $_GET['error'] == 'INVALID_CREDENTIALS'){ ?>
		* Invalid username or password<br />
	<? } ?>

    <input type="submit" value="Log in" />
</form>

user/profile.php

<?php

use \UserApp\Widget\User;

require_once('../must_authenticate.php');

$user = User::current();

?>

User id: <?= $user->user_id ?><br /><br />
Username: <?= ($user->login ?: '(not specified)') ?><br />
First name: <?= ($user->first_name ?: '(not specified)') ?><br />
Last name: <?= ($user->last_name ?: '(not specified)') ?><br />
Email: <?= ($user->email ?: '(not specified)') ?><br />

<a href="logout.php">Logout</a>

user/logout.php

<?php

use \UserApp\Widget\User;

require_once('../must_authenticate.php');

$user = User::current();
$user->logout();

header('Location: ../login.php');

Checking if a user is authenticated

bool User::authenticated()

Getting the currently authenticated user
