I already have a working Laravel PHP script online, but the file-upload page, user image mangement etc and its related database logic need a small yet solid upgrade. My priority is functionality: I’d like stronger data validation built into the upload flow so that bad or incomplete records never reach the database. Here’s what I’m aiming for: • Revamp the existing upload controller, model, and form so they reject invalid files and fields gracefully, returning clear error messages to the user. • Add server-side rules (Laravel Validator or Form Request) that cover size, mime-type, required columns, and any other sanity checks we agree on. • Ensure the database write is fully wrapped in a transaction so partial inserts can’t slip through. • Update or create unit tests so I can run php artisan test and immediately know everything passes. I’m not touching UI design, payment workflows, or search/filter modules right now—just this focused functionality enhancement. The code must stay compatible with my current Laravel version and follow PSR-12 style. Deliver the updated files, any new migration or seeder you create, and a quick setup note so I can pull, composer install, migrate, and see it work. If you keep it lean and efficient, we’ll be a great fit for future tweaks as well.
