custom login : Elgg.org

custom login

By TCB 392 days ago

I'm developing a plugin that will use a custom login page using Elgg 2.3.14. Currently I'm simply displaying a "Login" link with a hard-coded <a href> in an attempt to point to a login.php page at the root of my plugin directory. I'm using the walled_garden.php and have checked the administrative setting to "only allow logged in users to view content". Below are the relevant plugin files that I have modified:

/var/www/html/mod/auth0_login/start.php

<?php

elgg_register_event_handler('init', 'system', 'auth0_init');

function auth0_init() {

elgg_register_page_handler('auth0_login', 'auth0_page_handler');

elgg_extend_view('css/elgg', 'auth0_login/css');

}

function auth0_page_handler() {

echo elgg_view_resource('auth0_login');

}

/var/www/html/mod/auth0_login/views/default/page/walled_garden.php

<?php

/**

* Walled garden page shell

* Used for the walled garden index page

* @uses $vars['head'] Parameters for the <head> element

* @uses $vars['body'] The main content of the page

* @uses $vars['sysmessages'] A 2d array of various message registers, passed from system_messages()

// render content before head so that JavaScript and CSS can be loaded. See #4032

$messages = elgg_view('page/elements/messages', array('object' => $vars['sysmessages']));

$content = $vars["body"];

ob_start(); ?>

<?php echo $messages ?>

</div>

<a href="auth0_login/login.php">Login</a>

</div>

<?php

$body = ob_get_clean();

$body .= elgg_view('page/elements/foot');

$head = elgg_view('page/elements/head', $vars['head']);

echo elgg_view("page/elements/html", array("head" => $head, "body" => $body));

/var/www/html/mod/auth0_login/login.php

<?php

require __DIR__ . '/vendor/autoload.php';

// ... other use declarations

use josegonzalez\Dotenv\Loader;

// Setup environment vars

$Dotenv = new Loader(__DIR__ . '/.env');

$Dotenv->parse()->putenv(true);

use Auth0\SDK\Auth0;

$domain = getenv('AUTH0_DOMAIN');

$client_id = getenv('AUTH0_CLIENT_ID');

$client_secret = getenv('AUTH0_CLIENT_SECRET');

$redirect_uri = getenv('AUTH0_CALLBACK_URI');

$audience = getenv('AUTH0_AUDIENCE');

if($audience == ''){

$audience = 'https://' . $domain . '/userinfo';

}

$auth0 = new Auth0([

'domain' => $domain,

'client_id' => $client_id,

'client_secret' => $client_secret,

'redirect_uri' => $redirect_uri,

'persist_id_token' => true,

'persist_access_token' => true,

'persist_refresh_token' => true,

]);

$auth0->login();

The login.php isn't accessible because the walled_garden config is true. When I click the "Login" link, I get the error:

"You must be logged in to view the requested page".

How do I open access to this page in this situation? If I put the login.php in my elgg document root at /var/www/html/ everything works fine, but from within my plugin root, it doesn't.

You must to expose your custom URL throught Walled Garden in start.php:

elgg_register_plugin_hook_handler('public_pages', 'walled_garden', 'my_plugin_walled_garden_public_pages');

function my_plugin_walled_garden_public_pages($hook, $type, $pages) {
   $pages[] = 'auth0_login';
   return $pages;
}

Learn more.

Also, you can use this code in the mod/auth0_login/views/default/page/walled_garden.php:

echo elgg_view('output/url', [
   'href' => 'auth0_login/login',
   'text' => elgg_echo('login'),
]);

instead of:

<a href="auth0_login/login.php">Login</a>
