I am using cakephp, I working on Error Handling

I have follow http://book.cakephp.org/1.3/en/view/1188/Error-Handling

}

but I found Erro
Fatal error: Call to undefined method UsersController::cakeError() in D:\wamp\www\survey\app\Controller\UsersController.php on line 318

I think you are using CakePHP 1.3 and extending ErrorHandler defined here :

....\cake\libs\error.php

and as per this error404 is defined as :

function error404($params) {
    extract($params, EXTR_OVERWRITE);

    if (!isset($url)) {
        $url = $this->controller->here;
    }
    $url = Router::normalize($url);
    $this->controller->header("HTTP/1.0 404 Not Found");
    $this->controller->set(array(
        'code' => '404',
        'name' => __('Not Found', true),
        'message' => h($url),
        'base' => $this->controller->base
    ));
    $this->_outputMessage('error404');
}

in your …./app/app_error.php you have defined it as

function error404() {
        //$this->controller->set('file', $params['file']);
        $this->_outputMessage('error404');
}

and in php such type of method overloading is not allowed. I think you have got your answer.

what you can do is that you can create your own function in your extended AppError class and then pass error name or template name in that like

function customeError($errorMessage){
     $this->_outputMessage($errorMessage);
} 

and then on basis of different template names you can put conditions in _outputMessage() function and redirect user to different pages.
