How to display Custom Error message in Zend Framework?

Question

I have a ZF application. In my bootstrap.php I defined the routes for my application. Now, when I type an URL in the address bar that does not match any of the routes, I get a fatal error. I don't want that, I just want to show a 'page can not be found' error. How come the application throws a fatal error, instead of going to my error controller?

This is what my routes look like:

$router->addRoute('page1',
        new Zend_Controller_Router_Route_Static('page1', array(
            'controller' => 'mycontroller',
            'action' => 'index',
            'id' => '2626'
        ))
    );

For example, if I browse to /page2 I get a fatal error, because it goes to 'mycontroller' anyway, and tries to do stuff I do in that controller. But I don't want it to go there.

Thanks in advance for your replies.

Zend throws HTTP status codes based on what is happening in the inside. If it says Error 500 it is STILL an application error. Nevertheless. I have got the answer for your question! — Keval Domadia

ErrorController should be like this.

class ErrorController extends Zend_Controller_Action {

  public function errorAction() {
    $errors = $this->_getParam('error_handler');

    if (!$errors || !$errors instanceof ArrayObject) {
      $this->view->message = 'You have reached the error page';
      return;
    }

    switch ($errors->type) {
      case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ROUTE:
      case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_CONTROLLER:
      case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ACTION:
        // 404 error -- controller or action not found
        $this->getResponse()->setHttpResponseCode(404);
        $priority = Zend_Log::NOTICE;
        $this->view->error_code = $this->getResponse()->getHttpResponseCode();
        $this->view->message = "Page Not Found";
        $this->renderScript('error/error_404.phtml');
        break;
      default:
        // application error
        print_r($this->getResponse());
        $this->getResponse()->setHttpResponseCode(500);
        $priority = Zend_Log::CRIT;
        $this->view->error_code = $this->getResponse()->getHttpResponseCode();
        $this->view->message = 'Application error';
        if ($log = $this->getLog()) {
        $log->log($this->view->message, $priority, $errors->exception);
        $log->log('Request Parameters', $priority, $errors->request->getParams());
        $this->renderScript('error/error_500.phtml');
        }

    // conditionally display exceptions
        if ($this->getInvokeArg('displayExceptions') == true) {
                $this->view->exception = $errors->exception;
        }

        $this->view->request = $errors->request;
        $this->view->error_code = $this->getResponse()->getHttpResponseCode();
        $this->renderScript('error/error_500.phtml');
        break;
    }

    // Log exception, if logger available
    if ($log = $this->getLog()) {
      $log->log($this->view->message, $priority, $errors->exception);
      $log->log('Request Parameters', $priority, $errors->request->getParams());
    }

    // conditionally display exceptions
    if ($this->getInvokeArg('displayExceptions') == true) {
      $this->view->exception = $errors->exception;
    }

    $this->view->request = $errors->request;
  }

  public function getLog() {
    $bootstrap = $this->getInvokeArg('bootstrap');
    if (!$bootstrap->hasResource('Log')) {
      return false;
    }
    $log = $bootstrap->getResource('Log');
    return $log;
  }

}

Phew! You can define any HTTP Status Response Code using $this->getResponse()->HttpResponseCode()

Also, we per best practices (in quotes), check that LOGS are required. !
