tmp files in laravel 8 public folder - php

Question

When I upload files (move actually) to the public folder in laravel 8, they are stored as .tmp files and when I attempt to store files in storage folder, it says failed to open stream: permission denied. Is there some kind of write permission I should enable? or am I missing something in the code?
if($request->file('file')) {
$uniqueFileName = uniqid() . $request->file('file')->getClientOriginalName();
$post = new Post();
$post->name = request('name');
$post->email = request('email');
$post->doc = $uniqueFileName;
$request->file('file')->move(public_path('uploads/files',$uniqueFileName));
//I also tried to store files here, but says "failed to open stream: permission denied"
//$request->file('file')->store('uploads');
$post->save();
return redirect()->back();
}

Answer 1

You need to change the permissions using this command: chmod -R 777 storage

Answer 2

Try on terminal sudo chmod -R 777 public it will change the directory permission

Answer 3

had the same issue with a similar approach.
fixed it by manually changing the php.ini
changed the entry upload_max_filesize = 2000M
! dont try to change it within your scripts with ini_set(), it doesnt work for this entry. why? -> check changeable https://www.php.net/manual/en/ini.list.php !
mby php checks the file_size AFTER its uploaded and denies permission if it exceeds the value which is set? dont know. but works for me...
some folks may also run into:
PHP Warning: POST Content-Length of XXX bytes exceeds the limit of XXX bytes in Unknown on line 0
fixed it by manually changing the php.ini
changed the entry post_max_size = 2000M
