Subdomain routingSubdomain routing

•Create a custom route Class (we are using sfRequestHostRoute)

•specify your subdomain in route requirements•note: Don’t Forget! Routes of class sfRoute can still match this url without subdomains.

class sfRequestHostRoute extends sfRequestRoute{ // ... public function generate($params, $context = array(), $absolute = false) { $url = parent::generate($params, $context, $absolute); if (isset($this->requirements['sf_host']) && $this->requirements['sf_host'] != $context['host']) { // apply the required host $protocol = $context['is_secure'] ?

•Overload generate method (called when using link_to and url_for methods, etc.)•If this route has an sf_host requirement set, add this to the generated url, and prepend to the matching host•This will ensure links reroute to the new subdomain

class myRequestHostRoute extends sfRoute{ protected $_subdomains = array('foo', 'bar'), $_root = 'dev.localhost', $_default = 'www';

public function matchesUrl($url, $context = array()) { if (!in_array($context['sf_host'], $this->_subdomains)) { return false; } return parent::matchesUrl($url, $context); } // ...}
