Laravel 5.2 How To redirect All 404 Errors to Homepage

Laravel 8+ uses the Register method to check for exceptions now. You could use the following code to catch and redirect 404 errors.

app/Exceptions/Handler.php

    /**
     * Register the exception handling callbacks for the application.
     *
     * @return void
     */
    public function register()
    {
        $this->renderable(function (NotFoundHttpException $e, $request) {
            return redirect()->route('home');
        });
    }

You can find the details in the Laravel docs here.

For that, you need to do add few lines of code to render method in app/Exceptions/Handler.php file.

public function render($request, Exception $e)
{   
    if($this->isHttpException($e))
    {
        switch (intval($e->getStatusCode())) {
            // not found
            case 404:
                return redirect()->route('home');
                break;
            // internal error
            case 500:
                return \Response::view('custom.500',array(),500);
                break;

            default:
                return $this->renderHttpException($e);
                break;
        }
    }
   
        return parent::render($request, $e);      
}
