Laravel is a popular PHP development framework that makes it easy to build efficient web applications. While creating your application, you may encounter many HTTP errors such as 404 errors. This article will focus on how to redirect traffic in your Laravel application to a custom 404 error page.
Laravel provides a simple 404 error page by default, which contains just a simple message: "Not Found". While this is sufficient for simple websites, if your application needs to have more professional and personalized content, you may want to customize the 404 error page.
There are two ways to customize Laravel's 404 error page: using Lumen and using Laravel. In this chapter, we will explain how to customize a 404 error page using Laravel.
In Laravel, any HTTP error, including 404 errors, can be done through a handler. This is why you need to register a custom error handler in your Laravel application before modifying the 404 error page.
The first step is to open the App\Exceptions\Handler.php file and find the render method. This is the core code of the task, which is responsible for rendering the given exception. By default, Laravel uses 404 view files to render 404 errors. So we can override this method and write code in it to render a custom 404 page.
The following is a sample code to override the render method to handle the 404 error and redirect it to a custom page:
public?function?render($request,?Exception?$exception)
{
????if?($exception?instanceof?ModelNotFoundException?&&
????????$request->wantsJson())
????{
????????return?response()->json([
????????????'error'?=>?'Resource?not?found'
????????],?404);
????}
????if?($exception?instanceof?NotFoundHttpException)?{
????????return?response()->view('errors.404',?[],?404);
????}
????return?parent::render($request,?$exception);
}
In this code, we first add a case if the request If the resource is not a model, an error message in a custom JSON format is returned. We then add another condition where if a NotFoundHttpException error occurs, we will redirect to a custom 404 view file.
It is important to remember that we need to create custom 404 view files in the resources/views/errors directory so that Laravel can render the custom page correctly. When an exception handler in your code detects a 404 error, it will redirect to this file for rendering.
In addition to customizing the 404 page, you can also customize other HTTP error pages, such as 403, 500, or 503 pages. Just use the same approach but change the conditions in the exception handler accordingly.
Summary
When developing Laravel applications, handling common HTTP errors such as 404 errors is crucial. In this article, we learned how to customize 404 error pages using Laravel, including writing custom exception handlers and view files. By customizing your 404 error page, you can easily optimize the user experience and improve the usability of your application.

How do I define methods (actions) in a controller?
Jun 14, 2025 am 12:38 AM
Defining a method (also known as an action) in a controller is to tell the application what to do when someone visits a specific URL. These methods usually process requests, process data, and return responses such as HTML pages or JSON. Understanding the basic structure: Most web frameworks (such as RubyonRails, Laravel, or SpringMVC) use controllers to group related operations. Methods within each controller usually correspond to a route, i.e. the URL path that someone can access. For example, there may be the following methods in PostsController: 1.index() – display post list; 2.show() – display individual posts; 3.create() – handle creating new posts; 4.u
