Re: Throwing a custom 503 exception in CakePHP 2

The second suggestion calls for using require, instead of App::uses

in your bootstrap.php, something like 

require ROOT . DS . APP . DS . 'Error' . DS . 'exceptions.php';

And just have exceptions.php in app/Error, mimicking/mirroring placement in lib/Cake/Error.

You may need to double check if ROOT . DS . APP is the right combo of definitions to use.

I tried your second suggestion. In "app/Lib/Error" I created "exceptions.php" and put the "ServiceUnavailableException" class inside this file.

Then I wrote this into "bootstrap.php":

App::uses('exceptions', 'Lib/Error');

 But I get the same error?

Looking at App::uses(), it expects the first parameter to be a classname, rather than a file name

Perhaps doing App::uses('ServiceUnavailableException', 'Lib'), and renaming the file to ServiceUnavailableException.php might be better, and more in keeping with the convention of one class per file.

When Cake bootstraps its own exceptions (in lib/Cake/bootstrap.php), it does a require CAKE . 'Error' . DS . 'exceptions.php';  You could possibly follow their lead, and bundle all your exceptions in app/Error/exceptions.php, then require that from your bootstrap. Then you wouldn't need to use App::uses() at all.

Then I also put "App:uses()" inside bootstrap and inside controller class.

But still I got the same error.

I'm not sure what the best method of including the new exception type, from the bootstrap, other than a include_once() statement.. and that doesn't look nice.  I've always been a bit lazy and have just included the class definition for the new exception directly in the bootstrap.php, and that's not particularly nice either.

I need to give a 503 Service Unavailable HTTP header.

Normally I use these for 404 and 500 codes

throw new NotFoundException();  throw new InternalErrorException();

But I couldn't find relevant exception for 503 in CakePHP 2.2?

In my "app/lib/AppExceptionHandler.php" file I have this class/function that handles errors.

class AppExceptionHandler {      public static function handle($error) {       }

Edit:

• Inside "app/Lib" folder I created a file named "MyExceptions.php". I wrote the following code inside this file:

  class ServiceUnavailableException extends CakeException {    protected $_messageTemplate = 'Service is not available now';    }

• In "bootstrap.php" I wrote this:

  App::uses('MyExceptions', 'Lib');

• Then inside "MyNewController.php" file I wrote this:

  throw new ServiceUnavailableException("tryout");

But then I get this error when I throw this exception:

Fatal error: Class 'ServiceUnavailableException' not found in   /var/www/vhosts/example.com/httpdocs/app/Controller/MyNewController.php   on line 3560    Warning (2): Cannot modify header information - headers already sent by  (output started at   /var/www/vhosts/example.com/httpdocs/app/Controller/MyNewController.php:3560)  [APP/Lib/AppExceptionHandler.php, line 19]

What do I miss? Thank you
