Custom Error Pages in Laravel: A Step-by-Step Tutorial

When your Laravel application encounters errors or exceptions, it's essential to provide a user-friendly and informative error page. Laravel allows you to create custom error pages easily, ensuring a better user experience. In this step-by-step tutorial, we'll guide you through the process of creating and using custom error pages in Laravel.

Step 1: Create Custom Error Views

First, you need to create custom error views for each HTTP error code you want to handle. In your resources/views directory, create Blade templates for errors, such as `404.blade.php` for a 404 error page. Customize these views to match your application's design and messaging.

Step 2: Define Error Handlers

In Laravel, you can define custom error handlers in the `App\Exceptions\Handler` class. Open this class and locate the `render` method. You can add code to handle specific exceptions and return your custom error views.

        
public function render($request, Throwable $exception) {
    if ($this->isHttpException($exception)) {
        return $this->handleHttpException($exception);
    }
    return parent::render($request, $exception);
}
protected function handleHttpException(Throwable $exception) {
    $status = $exception->getStatusCode();    switch ($status) {
        case 404:
            return response()->view('errors.404', [], 404);
        // Add more cases for other error codes if needed
    }
}
    

Step 3: Configure Error Pages

Next, configure your Laravel application to use these custom error pages. In your `App\Exceptions\Handler` class, you can define which HTTP error codes should be handled and which views should be displayed for each error code.

        
protected $dontReport = [
    // ...
];
protected $dontFlash = [
    'password',
    'password_confirmation',
];
protected $dontRender = [
    \Symfony\Component\HttpKernel\Exception\HttpException::class,
];
public function register() {
    $this->reportable(function (Throwable $e) {
        // ...
    });
}
public function render($request, Throwable $exception) {
    // ...
}
    

Step 4: Testing Error Pages

Now it's time to test your custom error pages. Trigger different HTTP error codes within your application and ensure that the correct custom error views are displayed. This step is crucial to validate that your error handling is working as expected.

Step 5: Adding a Fallback

If you want to create a generic custom error page for unhandled exceptions, you can add a fallback view in your `render` method. This view will be displayed for exceptions that don't have a specific custom error view.

        
public function render($request, Throwable $exception) {
    if ($this->isHttpException($exception)) {
        return $this->handleHttpException($exception);
    }
    // Fallback for unhandled exceptions
    return response()->view('errors.generic', [], 500);
}
