How to implement guide with handling file uploads in php 8.1 using laravel: empty file input not triggering validation
I'm prototyping a solution and I'm working on a Laravel application where I need to handle file uploads. I have a form that allows users to upload a profile image, and I'm using Laravel's built-in validation to ensure that the uploaded file is actually a valid image. However, I'm running into an scenario where if the user does not select a file and submits the form, the validation rule doesn't trigger, and the file input seems to be ignored altogether. The relevant part of my form looks like this: ```html <form action="/upload" method="POST" enctype="multipart/form-data"> @csrf <input type="file" name="profile_image"> <button type="submit">Upload</button> </form> ``` In my controller, I'm using the following validation: ```php public function upload(Request $request) { $request->validate([ 'profile_image' => 'required|image|max:2048', ]); // Process the file upload... } ``` When I submit the form without selecting an image, it doesn't trigger the validation behavior for the `profile_image` input. Instead, it seems to just pass through to the next part of the controller. I expected Laravel to throw a validation exception and return the user back to the form with an behavior message. I've also checked my session configuration to ensure it's correctly set up and able to hold the validation messages. I've tried using `dd($request->all())` to see what's being sent, and it returns an empty array when no file is uploaded. Is there a specific setting or configuration in Laravel 8.x that I might be missing to enforce file upload validation correctly? Any insights would be greatly appreciated! I'm using Php 3.9 in this project.
