    Hi there

    I'm trying to upload a file to the assets folder. As a non-expert (javascript + BANano) person what I'm trying is not working yet. I've tried to adopt an example that I was previously provided as a solution to these file management things by Kiffi.

    I have attached here my example code for anyone willing to help me out. This is an example I have found on the internet and just updated it to suit my needs so that I can achieve my problem statement as per subject of this question.

    #if javascript
        function uploadFile(fileid){
            var fi = document.getElementById(fileid);
            var file = fi.files[0];       
            var url = './assets/upload.php';
            var xhr = new XMLHttpRequest();
            var fd = new FormData();
            xhr.open("POST", url, true);
            xhr.onreadystatechange = function() {
                if (xhr.readyState == 4 && xhr.status == 200) {
            fd.append("upload_file", file);
    #End If
    This I have tried to adopt for BAnano like this...

    Sub UploadIt(id As String)
    'get the file input
        Dim fi As BANanoElement = BANAno.GetElement($"#${id}"$)
    'get the selected files, if any
        Dim files() As String = fi.ToObject.GetField("files").Result
    'loop though each selected file
        For fCnt = 0 To files.Length - 1
    'create a new formdata
            Dim fd As BANanoObject
    "upload_file", files(fCnt))
    Dim result As String = BANAno.CallAjaxWait("./assets/upload.php","POST","",fd,True,Null)
    End Sub
    Both these in my event handler return a 'fail'

    Sub globalevent(event As BANanoEvent)
    Select Case event.ID
    Case "fu"
    "uploadFile"Array As String("fu"))
        End Select
    End Sub
    Thanks in advance for your help
