The key was to use a filter at the right place. Before "execution" :
too early, actions are not yet executed. After "execution" : too late,
nothing else can be executed after. So we have to replace "execution"
filter.
First, I added a singleton to your class. This way it's easier to use
in actions and in a filter : the access to the title is centralized.
[php]
protected static $instance = null;
/**
* @return sfTitleMaker
*/
public static function getInstance()
{
if (is_null(self::$instance)) {
self::$instance = new sfTitleMaker();
}
return self::$instance;
}
[/php]
Then, I made a new filter, extending sfExecutionFilter, and overriding
the executeView() method, using the precedent singleton to set Title.
[php]
class sfTitleMakerExecutionFilter extends sfExecutionFilter
{
protected function executeView($moduleName, $actionName, $viewName,
$viewAttributes)
{
sfContext::getInstance()->getResponse()->setTitle
(sfTitleMaker::getInstance());
parent::executeView($moduleName, $actionName, $viewName,
$viewAttributes);
}
}
[/php]
This way, I just have to call "sfTitleMaker::getInstance()->add
('part')" to add "part" to my title ;)
Example :
[php]
public function executeToto()
{
sfTitleMaker::getInstance()->add('test1');
sfTitleMaker::getInstance()->add('test2');
sfTitleMaker::getInstance()->add('test3');
}
[/php]
Nothing else, and it produces "test1 » test2 » test3".
