Laravel 5.4 fopen(): Filename cannot be empty

I want to upload image in laravel 5.4 Here’s the code:

if ($request->hasFile('image') && $request->image->isValid()) {
        $image = $request->image;

        $image_name = bcrypt($image->getClientOriginalName());

        Storage::disk('public')->putFileAs('images', $image, $image_name . '.' . $image->getClientOriginalExtension());

        $article->image($image_name);
    }

in FilesystemAdapter.php (line 146)

I checked the FileSystemAdapter.php and saw that the problem is in this line:

$stream = fopen($file->getRealPath(), 'r+');

When I var dump the $file variable it returns the correct info, but when I var_dump($file->getRealPath(); it says bool(false) and I can’t upload the image

Answer

We had this problem with Internet Information Services (IIS) for Windows® Server. And only thing needed was – permission for C:Windowstemp because it is set as upload_tmp_dir in php.ini for php7.
