Request->file returns null why? - php

Question

So I'm trying to create a Video store of sorts in which you can see the image of the movie, title, length and the option to delete it. The problem is when I try to upload an image it always returns null. Also I use Laravel 5.8.35
I tried with getClientOriginalExtension but it can't work since file returns null
Slika means Image
Žanr means Genre
Naslov means Title
Godina means Year
Filmovi means Movies
Trajanje means Lenght
Akcija means Action

As far as I can see there are two possibilities:
1. pass csrf-token in your form
2. add enctype="multipart/form-data" to your form.
Moreover you should save it to your storage and link it using symlink (use command php artisan storage:link) check the docs: https://laravel.com/docs/5.8/filesystem
