error400()
error400(\Exception $error) : void
Convenience method to display a 400 series page.
Parameters
| \Exception | $error | Exception |
Exception Renderer.
Captures and handles all unhandled exceptions. Displays helpful framework errors when debug > 1. When debug < 1 a CakeException will render 404 or 500 errors. If an uncaught exception is thrown and it is a type that ExceptionHandler does not know about it will be treated as a 500 error.
You can implement application specific exception handling in one of a few ways:
Exception.rendererThis controller method is called instead of the default exception handling. It receives the thrown exception as its only argument. You should implement your error handling in that method.
Using a subclass of YAExceptionRenderer gives you full control over how Exceptions are rendered, you
can configure your class in your core.php, with Configure::write('Exception.renderer', 'MyClass');
You should place any custom exception renderers in app/Lib/Error.
