CakePHP: Redirecting all 404 errors to the homepage?

Question

Is there a way or a function within a controller that tells if a 404 error was triggered? I would like everyone to redirect at the homepage instead of seeing a 404 page.

Answer 1

For CakePHP 2.x I used

// app/Lib/Error/AppExceptionRenderer.php
controller->redirect('/');
    }

}

//app/Config/Core.php

Configure::write('debug', 0);
Configure::write('Exception', array(
        'handler' => 'ErrorHandler::handleException',
        //'renderer' => 'ExceptionRenderer',
        'renderer' => 'AppExceptionRenderer',
        'log' => true
    ));
