In this episode, we're diving into how to create custom error pages for your app—focusing on the 404 not found page, but the technique works for any error status. Instead of handling this manually in every possible error spot, we make it automated and flexible by borrowing some inspiration from frameworks like Laravel.
Here's what we do: We make error templates (like 404.twig
) inside an errors
directory, so whenever a particular exception is triggered (like a 404), our exception handler can check for a template that matches the error code. If it exists, we render that page nicely with all the markup you want—instead of just dumping a plain message.
The episode covers how to get the status code from an exception, check if a matching error view exists, and render that view if it does. If there's no matching view, we just fall back to the default error handling. We also tweak our view class to add a method to check if a template exists, making it seamless to handle as many error codes as you want.
Once it's all wired up, you can easily create beautiful custom error pages for anything—404s, 500s, or whatever your app throws at the user, giving you full control over the error experience.
