Controller connects the template file with model. That means, the data from model will be passed to view (template file) using controller.
Each controller must have ::main($handler) function, which will be called automatically from loader.php.
Example controller:
class AuthController
{
private static $handler;
public static function main($handler) {
self::$handler = $handler;
if (isset($GLOBALS["request"]->getUrl()->getLink()[1])) {
switch($GLOBALS["request"]->getUrl()->getLink()[1]) {
case 'login':
self::login();
break;
}
}
}
public static function login() {
self::$handler::setParameters([
'name'=>'xx',
'mail'=>'yy'
]);
}
}
The $handler contain reference to Handler of the file (e.g. LatteHandler). So the Handler will obtain parameters that will be available in template file using controller.
