This view requires three variables:

•

$join_action : The form action that will allow a user to join an existing room

•

$nonce : A security token that prevents the form from being submitted fraudulently or
repeatedly

$create_action : The form action that allows a user to create a new room
The $nonce is used in both forms because there's no way for both forms to be submitted simultaneously (and
even if there were, that's not a behavior this app supports).

•

Generating Variables for Output
To create the variables for outputting the home view, go back into the Home controller ( class.home.inc.php ) and
add the following bold code:

/**
* Loads and outputs the view's markup
*
* @return void
*/
public function output_view( )
{
$view = new View('home');
$view->nonce = $this->generate_nonce();

// Action URIs for form submissions
$view->join_action = APP_URI . 'room/join';
$view->create_action = APP_URI . 'room/create';

$view->render();
}
