Some notes for symfony

View Template Shortcuts

• $sf_context: The whole context object (instance of sfContext)
• $sf_request: The request object (instance of sfRequest) 
• $sf_params: Parameters of the request 
• $sf_user: The current user session object (instance of sfUser)

Get XML information in symfony 1.4

When parse a remote xml file, I use sfWebBrowserPlugin and get the right result, like this way:

in actions code

$tar = new sfWebBrowser();
$tar->post(url_for('MsgTransfer/Recommender', true), http_build_query($this->form->getValues()));
$this->xml = $tar->getResponseXML(); 

in template code

php echo $xml->string;

then i get the error message:

Fatal error: Call to undefined method SimpleXMLElement::__toString() in /usr/share/php/symfony/escaper/sfOutputEscaperObjectDecorator.class.php on line 98

The solution to solve is use:

php echo $sf_data->getRaw('xml')->string;
