Ive been trying to figure out how to do my own file upload from a dropped file. Ive cobbled together from multiple articles and got the following:-
<!DOCTYPE html>
<html lang="en">
<head>
<script src="jquery-3.4.1.js"></script>

<style>
#testDiv {
    height:150px;
    width:150px;
    border: 1px solid black;
}
</style>

</head>
<body>
<div id="testDiv">nnn</div>
</body>
</html>

<script>
$(document).ready(function() {
$('#testDiv').on('dragover', function(e) {
        e.preventDefault();
        e.stopPropagation();
    });

$('#testDiv').on('dragenter', function(e) {
        e.preventDefault();
        e.stopPropagation();
    });

$('#testDiv').on('drop', function(e){
    if(e.originalEvent.dataTransfer && e.originalEvent.dataTransfer.files.length) {
        e.preventDefault();
        e.stopPropagation();
        myOwnCallBack(e.originalEvent.dataTransfer.files);
        }
    });
});

function myOwnCallBack(file) {
    let data = new FormData();

    for(var i = 0;i<file.length;i++){
        data.append("file_"+i, file[i]);
    }
    data.append("test1", "value1");
    data.append("test2", "value2");

    $.ajax({
        data: data,
        type: "POST",
        url: "file-uploader.php",
        cache: false,
        contentType: false,
        processData: false,
        xhr: function() {
            let myXhr = $.ajaxSettings.xhr();
            if (myXhr.upload) myXhr.upload.addEventListener('progress', progressHandlingFunction, false);
            return myXhr;
        },
        success: function(reponse) {
        alert("uploaded");
        }
    });
}

function progressHandlingFunction(e) {
    if (e.lengthComputable) {
        console.log((e.loaded / e.total * 100) + '%');

        if (e.loaded === e.total) {
            console.log("Upload finished.");
        }
    }
}
</script>

Open in new window


My test values transfer fine, but the file(s) dont transfer.

Can anyone see what Im doing wrong with the files?

Thank you in advance
