Cakephp: How would I route all missing controller/action calls to a single, general error page?

Question

I've got a cakephp app that I'm trying to get to serve up the Pages::404 function (and corresponding view) whenever Cake encounters any error (missing controller, action, etc).

What's the best way to do that?

Answer 1

Are you in the controller when you are trying to redirect to the 404 error page?

Well if that is the case, you can walk around the problem like this:

Copy and paste the error layout (error404.ctp) from the cake core library directory into yours app/views/errors/

Then add the following line whenever you encounter an error inside a controller.

$this->cakeError('error404',array(array('url'=>'/')));

Oh, another way to handle this is to edit the routes.php file in app/config

CakePHP Official site Routes-Configuration

I don't have a working copy of CakePHP at the moment, so I would just describe the basic logic here(what you can do inside the routes.php file)

Redirect traffic with specific url patterns(say, http://yourwebsite/validController/validFunction/validParam) to their corresponding destinations respectively. Redirect all other traffic (missing controller, model, view, etc) to 404 page.

Hope that helps:)

Cake automatically throws a 404 error for missing methods or controllers. While in debug mode, this error takes the form of a detailed error message containing instructions, like:

Missing Controller

Error: FooController could not be found.

Error: Create the class FooController below in file: > app/controllers/foo_controller.php

Notice: If you want to customize this error message, create app/views/errors/missing_controller.ctp

In production mode (debug = 0) the message just looks like this:

Not Found

Error: The requested address '/foo' was not found on this server.

These error pages are defined in cake/libs/view/errors/. As the message in debug mode says, you can create your own, custom error pages (using the same name as the ones in the cake/ directory) in app/views/errors/.

If you want to execute a custom function on errors, you'll best put it in the AppError Controller as described in Error Handling.
