Laravel Custom Exception Handlers


Laravel throws a large number of exceptions and is very easy to customize them to suit our needs as required.

Note: These exceptions are most helpful if you’re building an API.

The code for common exception handler lies in the {project_root}/app/Exceptions/ folder, named Handler.php. The default file looks like this in Laravel 5.7.

<?php namespace App\Exceptions; use Exception; use Illuminate\Foundation\Exceptions\Handler as ExceptionHandler; class Handler extends ExceptionHandler { /** * A list of the exception types that are not reported. * * @var array */ protected $dontReport = [ // ]; /** * A list of the inputs that are never flashed for validation exceptions. * * @var array */ protected $dontFlash = [ 'password', 'password_confirmation', ]; /** * Report or log an exception. * * @param \Exception $exception * @return void */ public function report(Exception $exception) { parent::report($exception); } /** * Render an exception into an HTTP response. * * @param \Illuminate\Http\Request $request * @param \Exception $exception * @return \Illuminate\Http\Response */ public function render($request, Exception $exception) { return parent::render($request, $exception); } }

Some of the common exceptions that we’re going to handle in this tutorial are AuthenticationException, MethodNotAllowedHttpException, ModelNotFoundException, NotAcceptableHttpException, NotFoundHttpException, PostTooLargeException, ValidationException.

Below is the explanation for each variable, functions and handler implemented.

protected $dontReport = [] is the array of exceptions that Laravel wouldn’t report. Here we’re going to mention the exceptions that we don’t want laravel to report.
