Yii forward with params

August 30, 2012 — JaZahn

Yii’s forward doesn’t work with passing params to actions. I.e. This doesn’t work: $this->forward(“/mycontroller/myaction/1/2”);

Because of the way urlmanager works I made the decision early on to have all action parameters take on the var names $id and $id2. So in the main config:

'components'=>array(
			// uncomment the following to enable URLs in path-format
			'urlManager'=>array(
				'urlFormat'=>'path',
				'rules'=>array(
					'<controller:\w+>/<id:\d+>'=>'<controller>/view',
					'<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
					'<controller:\w+>/<action:\w+>/<id:\d+>/<id2:\d+>'=>'<controller>/<action>',
					'<controller:\w+>/<action:\w+>'=>'<controller>/<action>',
					'<controller:\w+>/<action:\w+>/<cact:\w+>'=>'<controller>/<cact>',
				),
			),

So I used Controller.php in the components directory to override the forward method like so:

	 /**
	 * Overloading CController::forward
	 * added the routeArr lines so the ids are passed
	 */
	public function forward($route,$exit=true){
		//error_log("Controller::forward");
		$routeArr = explode("/", $route);
		if(isset($routeArr[3]))
			$_GET['id'] = $routeArr[3];
		if(isset($routeArr[4]))
			$_GET['id2'] = $routeArr[4];

		parent::forward($route, $exit);

	}

And that’s it.

Yii Javascript redirect: jsredirect

August 30, 2012 — JaZahn

One of the platforms I have to develop for is iSites. This is a Harvard grown LMS that is complicated and annoying, but functional.

Since I have to develop tools that fit within this framework I have to work around its limitations. One of the simpler to understand limitations is the idea of not having control of the headers sent. Since by the time it gets to my tool, the page has already started loading, output has already been sent, so doing a redirect with PHP’s header function is impossible.

Yii has 2 ways to forward things through the controller. redirect and forward. Redirect uses header and forward doesn’t change the URL. So the best way to forward within isites is to use a js forward. I.e. document.location = “www.google.com”

So in the controller.php in components which extends CController I added a method jsredirect:
 https://github.com/jazahn/Quizmo/blob/ma…

	protected function jsredirect($url){
		// set the redirect in a session
		Yii::app()->session['jsredirect'] = $url;

		// forward to the jsredirect action
		$this->forward('/site/jsredirect');
	}

This just sets a session var for the redirect and forwards to site/jsredirect so in SiteController.php I have

public function actionJsredirect(){
		
		if(isset(Yii::app()->session['jsredirect'])){
			$this->render('jsredirect',array(
				'url'=>Yii::app()->session['jsredirect'],
			));
		}
		
	}

And then in the jsredirect template file we have

<script>
window.location.replace("{$url}");
</script>
