File not uploading to server via dropzone script?

Question

PHP

Hello.
I upload files to the server through the dropzone script. In other words. Just transferred the file to the browser and it should load itself.
This is the form code.

<form action="../../assets/global/plugins/dropzone/upload.php" class="dropzone" id="my-dropzone" enctype="multipart/form-data" method="POST">
</form>

This is the code for the file that does the download.

<?php
  $uploadfile = $_SERVER['DOCUMENT_ROOT']."/theme/assets/data/menadger/".$_FILES['somename']['name'];
  move_uploaded_file($_FILES['somename']['tmp_name'], $uploadfile);
print_r($_FILES);
echo $_SERVER['DOCUMENT_ROOT']."/theme/assets/data/menadger/".$_FILES['somename']['tmp_name'];
var_dump($_FILES);
?>

When I upload via a regular form with a button, everything works.
I also looked in the browser network. when I transfer the file, the script works but does not transfer to the correct folder.
