We are using $_FILES to check files post data in core php. Which class can use in Magento 2 to check files post data?


2 Answers 2


this will help

$files = $this->getRequest()->getFiles();

Here is Magento2 :: Accessing $_FILES using Magento Framework

use Magento\MediaStorage\Model\File\UploaderFactory;

protected $uploaderFactory;

public function __construct(
    UploaderFactory $uploaderFactory    
) {
    $this->uploaderFactory = $uploaderFactory;  

    $uploader = $this->uploaderFactory->create(['fileId' => $fileId]);
    $result = $uploader->save($path);

Where $fileId is your name of input file

  • Name of input field is groups[vbanktransfer][nineform] in that case what will be the $fileId ?? <input id="vbanktransfer-nineform" name="groups[vbanktransfer][nineform]" data-ui-id="widget-form-renderer-fieldset-element-0-file-groups-vbanktransfer-nineform" value="" type="file"> Commented Jul 13, 2020 at 16:17
  • It will create the issue (File size is empty)
