Catching error exceptions in Laravel 4 - php

Question

From the documentation it says we can catch all 404 like so:
App::missing(function($exception)
{
return Response::view('errors.missing', array(), 404);
});
And we can also do things like:
App::abort(404);
App::abort(403);
All 404 gets handled by the App::missing
All other errors gets handled by:
App::error(function( HttpException $e)
{
//handle the error
});
But the question is How do i handle each of the error like if its a 403 I will display this if its a 400 I will display another error

Answer 1

Short answer: if your custom App::error function does not return a value, Laravel will handle it. Check the docs
Code sample for custom error views and/or logic:
App::error(function(Exception $exception, $code){
// Careful here, any codes which are not specified
// will be treated as 500
if ( ! in_array($code,array(401,403,404,500))){
return;
}
// assumes you have app/views/errors/401.blade.php, etc
$view = "errors/$code";
// add data that you want to pass to the view
$data = array('code'=>$code);
// switch statements provided in case you need to add
// additional logic for specific error code.
switch ($code) {
case 401:
return Response::view($view, $data, $code);
case 403:
return Response::view($view, $data, $code);
case 404:
return Response::view($view, $data, $code);
case 500:
return Response::view($view, $data, $code);
}
});
The above snippet could be inserted in app/start/global.php after the default Log::error handler, or better yet in the boot method of a custom service provider.
EDIT: Updated so the handler only processes codes you specify.
