Drag and Drop Jquery upload to PHP - php

Question

I have seen many topics about this problem but none of them got a legit answer or a including PHP file.
I want to make a drag & drop saving tool. The problem is that my files are not getting uploaded to my ftp folder.
I got the following code:
HTML:
<div id="drop_zone">
<p>Drop Here</p>
</div>
<form enctype="multipart/form-data" id="yourregularuploadformId">
<input type="file" name="files[]" multiple="multiple">
</form>
JS:
$(function() {
var dropZone = document.getElementById('drop_zone');
dropZone.addEventListener('dragover', handleDragOver, false);
dropZone.addEventListener('drop', handleFileSelect, false);
etc.... dropping part
function handleFileSelect(evt) {
evt.stopPropagation();
evt.preventDefault();
files = evt.dataTransfer.files;
uploadFile(files);
etc... getting file to my method
function uploadFile(droppedFiles){
// add your files to the regular upload form
var uploadFormData = new FormData($("#yourregularuploadformId")[0]);
if(droppedFiles.length > 0) { // checks if any files were dropped
for(f = 0; f < droppedFiles.length; f++) { // for-loop for each file dropped
uploadFormData.append("files[]",droppedFiles[f]); // adding every file to the form so you could upload multiple files
}
}
// the final ajax call
alert(uploadFormData);
$.ajax({
url : "php/uploadFile.php", // use your target
type : "POST",
data : uploadFormData,
cache : false,
contentType : false,
processData : false,
success : function(ret) {
alert(ret);
}
});
}
Got the above code from another topic. (alert(uploadFormData); -> gives me a Formdata aboject)
PHP:
move_uploaded_file($_FILES["file"]["tmp_name"],
"ftp/" . $_FILES["file"]["name"]);
echo "Stored in: " . "upload/" . $_FILES["file"]["name"];
Can't make it work :<
The message i get from the callback function in my JS is:
Undefined index: file

Your PHP code needs to iterate over all of the files in the request. Based on your javascript, your PHP code should look something like this:
foreach ($_FILES["files"] as $file) {
move_uploaded_file($file['tmp_name'], $target);
}
The $target variable must point at the local destination for your file. See the PHP manual for more details.
