Hey Im following the book and on the part that we define that you cant create an Issue without having a project linked to it, Im having the following problem, apparently the call to filterchain is failing, where is it defined or how can I fix this?

Undefined variable: filterchain

/Users/user/Sites/yii11/trackstar/protected/controllers/IssueController.php(217)




205      public function filterProjectContext($filterChain)

206      {

207         //set the project identifier based on either the GET or POST input

208         //request variables, since we allow both types for our actions

209          $projectId = null;

210          if(isset($_GET['pid']))

211               $projectId = $_GET['pid'];

212          else

213               if(isset($_POST['pid']))

214                $projectId = $_POST['pid'];

215        $this->loadProject($projectId);

216          //complete the running of other filters and execute the requested action

217          $filterchain->run();

218      }

219 }

Edit line 217 above so it says $filterChain->run(); instead (PHP is a case-sensitive language, and you are actually referring to 2 variables above (filterchain and filterChain), one of which is undefined and used resulting to your error. :)

hey, i have problem too at page 115 (adding some filter logic)

i’ve follow code on book. here my code,




        private $_project = null;

	protected function loadProject($project_id){

		if($this->_project === null)

		{

			$this->_project=Project::model()->findByPk($project_id);

			if($this->_project === null)

			{

				throw new CHttpException(404,'The Requested project does not exist.');

			}

		}

		return $this->_project;

	}

	public function filterProjectContext($filterChain)

	{

		$projectId = null;

		

		if(isset($_GET['pid']))

			$projectId = $_GET['pid'];

		else

			if(isset($_POST['pid'])

				$projectId = $_POST['pid'];

				

		$this->loadProject($projectId);

		$filterChain->run();

	}

	/**

	 * @return array action filters

	 */

	public function filters()

	{

		return array(

			'accessControl', // perform access control for CRUD operations

			'projectContext + create'

		);

	}
