Developer Notes

Since 1.1.1, you can make use of 'hybridauth:authenticate', $provider plugin hook to perform some actions, when the user is authenticated with a provider. This might be a good place to post stuff to user's wall or to grab a profile picture.

Example of how to post to the user's wall that the user Joined the site:


// do stuff when the user is authenticated with one of the providers
elgg_register_plugin_hook_handler('hybridauth:authenticate', 'all', 'elgg_hybridauth_on_authenticate');

function elgg_hybridauth_on_authenticate($hook, $provider, $return, $params) {

	$user = elgg_extract('entity', $params);

	try {
		$ha = new ElggHybridAuth();
		$adapter = $ha->getAdapter($provider);
		if ($adapter->isUserConnected()) {
			$status = $user->name . ' just joined ' . elgg_get_config('sitename') . ' at ' . elgg_get_site_url();
			$adapter->setUserStatus($status);
		}
	} catch (Exception $e) {
		// Something is wrong
	}
}

Upgrading

To 1.3

  • For performance reasons, HYBRIDAUTH_PUBLIC_AUTH is not longer defined. Call elgg_get_plugin_setting('public_auth', 'elgg_hybridauth') where needed.

  • base_url and debug_file are no longer set via plugin settings. They are set dynamically using current installation path and wwwroot.

  • Due to recent changes in LinkedIn scopes, HybridAuth was producing unreliable results. HA LinkedIn class and LinkedIn wrapper were replaced with custom implementation for the sake of stability. https://developer.linkedin.com/support/developer-program-transition
