Laravel and DropzoneJS file uploaded with different extension - laravel

Question

I created a form here with Laravel and DropzoneJS and I tried uploading a Gimp file (.xcf) and when it is uploaded it is saved in S3 as the following
<random-name>.
without the "xcf" extension just random name ending with a dot.
Also, I created a text file and renamed it to test.xcf when I tried uploading that file it was uploaded with the .txt extension.
Here is my UploadController.php which handles the upload:
<?php
namespace App\Http\Controllers;
use App\Upload;
use Illuminate\Http\Request;
class UploadController extends Controller
{
public function upload(Request $request)
{
$originalName = $request->file('file')->getClientOriginalName();
$fileSize = $request->file('file')->getClientSize();
$path = $request->file('file')->store('documents');
$explode = explode('documents/', $path);
$name = $explode[1];
$uniqueId = $this->generateUniqueId();
$upload = new Upload();
$upload->unique_id = $uniqueId;
$upload->name = $name;
$upload->path = $path;
$upload->original_name = $originalName;
$upload->size = $fileSize;
if ($upload->save())
{
return response()->json([
'original_name' => $originalName,
'size' => $fileSize,
'url' => env('AWS_URL') . $path,
'id' => $uniqueId,
'status' => 'OK'
]);
}
return response()->json(['status' => 'BAD', 'message' => 'There was a problem saving your file.']);
}
public function generateUniqueId()
{
$result = '1';
$result .= rand(100000000, 999999999);
while(Upload::where('unique_id', '=', $result)->first())
{
$result = '1';
$result .= rand(100000000, 999999999);
}
return $result;
}
}
I've got no idea why it's doing that.

Answer 1

I suggest, you generate your own hash for filename, like I do in this code:
$file = $request->file('csv');
$path = $file->storeAs(
'csv',
md5($file->getClientOriginalName()) . $file->getClientOriginalExtension(),
's3'
);
You can also add uniqid() to md5 input

Answer 2

If you're using laravel 5+ then you should get the extension also using this.
$extension = $file->getClientOriginalExtension();
This will work fine.
