Laravel multiple file upload - laravel

Question

I am trying to upload files (they can be any type), and I have a problem uploading file with certain way.
I am able to upload a file correctly using $request->file('file_name') and Storage::disk($disk)->put($path, $file);. However, $file parameter can only be through $request->file('file_name').
However, because of the way I want to upload multiple orders with multiple files like below:
Controller
foreach ( $filesArray as $key => $files ) {
$path = 'order/'.$order->id;
if ( isset($files[$i]) && !empty($files[$i]) ) {
for ( $j = 0; $j < count($files[$i]); $j++ ) {
$uploadedFile = FileHelper::upload($files[$i][$j], $path);
$orderFile = [];
$orderFile['order_id'] = $order->id;
$orderFile['file_id'] = $uploadedFile->id;
OrderFileModel::create($orderFile);
}
}
}
FileHelper
static public function upload($file, $path, $disk = 's3')
{
$fileOrm = new FileModel;
$fileOrm->size = $file->getSize();
$fileOrm->extension = $file->getExtension();
$fileOrm->bucket_name = self::$BUCKET_NAME;
$fileOrm->type = self::getFileType($file->getExtension());
$fileOrm->key = Storage::disk($disk)->put($path, $file);
$fileOrm->created_time = now();
$fileOrm->save();
return $fileOrm;
}
I've also attached images where I see the difference.
One with $request->file('file_name') and the other with just $request->file_name which is blob type.
The image below would return error saying fstat() expects parameter 1 to be resource, object given
How could I solve this problem?
Any advice or suggestion would be appreciated. Thank you.

Do you get your file list to use $request->files? If you do, change to $request->allFiles(). This method will convert File object to UploadedFile object.

Actually just put an array in your input file like this
<input type="file" name="files[]">
<input type="file" name="files[]">
<input type="file" name="files[]">
<input type="file" name="files[]">
NOTE: you need to enctype="multipart/form-data" enabled in your form.
Then in your controller, you can loop the input file by doing such
foreach($request->file('files') as $index => $file){
// do uploading like what you are doing in your single file.
}

Try:
$this->validate($request, [
'files.*' => 'file|mimes:...'
]);
foreach ($request->files as $file) {
$fileName = (string)Str::uuid() . '.' . $file->getClientOriginalExtension();
try {
if (\Storage::disk('s3')->put($fileName, file_get_contents($file))) {
FileModel::create([
'size' => '...',
'extension' => '...',
'bucket_name' => '...',
'type' => '...',
'key' => '...',
'created_time' => '...'
]);
}
} catch (\Exception $e) {
// ...
}
}

You might have been lucky before that some type casting on your $image object made a string out of it, I guess a simple chnage of your last line to
$disk->put($path, $file->__toString());
will fix the problem and is safer anyway as the "put" method officially only accepts strings (and looking at the implmentation also php resources). That should keep you compatible to changes in the long run.
