Controller

$req->file('meta')->store('app');
// $path = Storage::putFile('app', $req->file('meta'))
}
error
Symfony \ Component \ Debug \ Exception \ FatalThrowableError (E_ERROR)
Call to a member function store() on null
Here is an image of the error
Does anybody know what i should do about this?

Answer 1

Add enctype="multipart/form-data" to your <form> tag in your blade:
<form method="post" name="type" action="songs" enctype="multipart/form-data">
Based on your blade file you can see that the file meta being uploaded is not required, so in your controller, you need to check if the file was sent before calling the store method on it. Check this:
public function create(Request $req, $type) {
$this->authorize('is_admin');
$file = $req->file('meta') ? $req->file('meta')->store('app') : null;
}
