Hey developers, today I’m going to show how to create custom error page in Laravel. We’re able to create custom error page for a specific error. In this article, I’ll create custom page for 404 error.

  1. HTTP Status Codes
  2. Create 404 View File
  3. Modify Exceptions Handler

1. HTTP Status Codes

Here’s the list of HTTP status codes:

$http_status_codes = array(

);

2. Create 404 View File

Go to resources/views folder and create a folder named errors. In the errors folder, create a file called 404.blade.php. So the location of our 404 page is resources/views/errors/404.blade.php.

In this file, you can set your custom design. I’m going to set a text only:

404.blade.php
<!DOCTYPE html>
<html>
<head>
    <title>Page Not Found</title>
</head>
<body>
 
This is the custom 404 error page.
 
</body>
</html>

3. Modify Exceptions Handler

Open app/Exceptions/Handler.php file and find the render() method. We’ll modify the render() function only. Here’s the modified code:

public function render($request, Exception $exception)
{
    if ($this->isHttpException($exception)) {
        if ($exception->getStatusCode() == 404) {
            return response()->view('errors.' . '404', [], 404);
        }
    }
 
    return parent::render($request, $exception);
}

In this file, I’m checking status code 404 for the 404 error page. Like this, you can set condition for another error. Let’s see the code for 404 & 500 errors:

public function render($request, Exception $exception)
{
    if ($this->isHttpException($exception)) {
        if ($exception->getStatusCode() == 404) {
            return response()->view('errors.' . '404', [], 404);
        }
         
        if ($exception->getStatusCode() == 500) {
            return response()->view('errors.' . '500', [], 500);
        }
    }
 
    return parent::render($request, $exception);
}

We’ve created the custom page for 404 error & set condition in exceptions handler file. Now let’s see the output:
