Laravel The picture failed to upload - image

Question

I'm working on a Laravel 5.4 app and the picture I try to upload is not moving to my disk.
Could you help me ?
My form:
<form class="form-horizontal" role="form" method="POST" action="{{ route('adminPostNews') }}" accept-charset="UTF-8" enctype="multipart/form-data">
{{ csrf_field() }}
<div class="form-group{{ $errors->has('picture') ? ' has-error' : '' }}">
<label for="picture" class="col-md-1 control-label">Photo</label>
<div class="col-md-6">
<input type="file" id="picture" name="picture">
#if ($errors->has('picture'))
<span class="help-block">
<strong>{{ $errors->first('picture') }}</strong>
</span>
#endif
</div>
</div>
<div class="form-group">
<div class="col-md-6 col-md-offset-4">
<button type="submit" class="btn btn-primary">
Ajouter
</button>
</div>
</div>
</form>
Controller:
public function store_actualites(Request $request)
{
$this->validate($request, [
'picture' => 'required|mimes:jpeg']);
if($request->file('picture'))
{
$file = $request->file('picture');
$extension = $file->getClientOriginalExtension();
Storage::disk('news')->put($file->getFilename().'.'.$extension, File::get($file));
}
}
My disk is ok, Laravel is giving the name of the file but the upload wont works.

Answer 1

You are not passing correctly the file name, try this:
//Save image
if ($request->hasFile('picture')) {
$file = $request->file('picture');
$fileName = $file->getClientOriginalName();
Storage::disk('news')->put($fileName, File::get($file));
}

Answer 2

ok, maybe the first answer will be: server file upload size limit !
Second, here is my new code:
$file = $request->file('picture');
$extension = $file->getClientOriginalExtension();
Storage::disk('news')->put($file->getFilename().'.'.$extension, file_get_contents($file));
I failed to use something different of "file_get_contents".
