Re: map domain name to module

Michael Depetrillo wrote:

Has anyone written any code to map a domain name to a specific module? I would like to be able to have a admin-specific-domain.com parked on top of my application and then route all requests to the admin module.

Small modification of code:

$frontController = Zend_Controller_Front::getInstance();
$frontController->setControllerDirectory(array('default' => '../controllers/',
							   'admin' => '../admin/controllers/'));

$router = new Zend_Controller_Router_Rewrite();
$router->removeDefaultRoutes();

$router->addRoute('default', new SmartShop_Controller_Router_DefaultSubdomainRoute(
    array(),
    $frontController->getDispatcher(),
    $frontController->getRequest()
));

foreach ($config->routes as $route) {
    $router->addRoute(
	   $config->routes->key(),
	   new SmartShop_Controller_Router_SubdomainRoute(
	        $route->url,
	        $route->defaults? $route->defaults->asArray() : null,
	        $route->requirements? $route->requirements->asArray() : null
	  )
    );
}

$frontController->setRouter($router);
$frontController->dispatch();


class SmartShop_Controller_Router_SubdomainRoute extends Zend_Controller_Router_Route

        if(isset($this->_requirements['module']) &&
           $module != $this->_requirements['module']
        ) {
            return false; // this route failed
        }

        $params = parent::match($path);
        if ($params) {
