Show a progress on multiple file upload Jquery/Ajax

Question

I have upload form that allows users to upload multiple files. I decided that a progress bar would be good if the files are quite large. Below is my source code. I am new to

This is your HTML form

This is your JQuery and ajax. By default the fileInput is hidden.

Upload Button clicked

$("#btnupload").click(function(e) {

    $("#fileupload").click();
    e.preventDefault();

});


$('#fileupload').change(function (e) {

    $("#imageuploadform").submit();
    e.preventDefault();

});

$('#imageuploadform').submit(function(e) {

    var formData = new FormData(this);

    $.ajax({
        type:'POST',
        url: 'ajax/uploadImages',
        data:formData,
        xhr: function() {
                var myXhr = $.ajaxSettings.xhr();
                if(myXhr.upload){
                    myXhr.upload.addEventListener('progress',progress, false);
                }
                return myXhr;
        },
        cache:false,
        contentType: false,
        processData: false,

        success:function(data){
            console.log(data);

          alert('data returned successfully');

        },

        error: function(data){
            console.log(data);
        }
    });

    e.preventDefault();

});


function progress(e){

    if(e.lengthComputable){
        var max = e.total;
        var current = e.loaded;

        var Percentage = (current * 100)/max;
        console.log(Percentage);


        if(Percentage >= 100)
        {
           // process completed  
        }
    }  
 }

Your php code looks like this

$path);

                                  $filename = "image_" . $date . "_" .$uid . "." . $ext;
                                  $this->createthumb($i,$filename);

                                    // move uploaded file from temp to uploads directory
                                  if (move_uploaded_file($_FILES['image']['tmp_name'][$i], $path))
                                  {
                                    //$status = 'Image successfully uploaded!';
                                      //perform sql updates here

                                  }
                                  else {
                                    $status = 'Upload Fail: Unknown error occurred!';
                                  }


                          }
                          else {
                            $status = 'Upload Fail: Unsupported file format or It is too large to upload!';
                          }
                    }
                    else {
                      $status = 'Upload Fail: File not uploaded!';
                    }
                }
              }
            else {
              $status = 'Bad request!';
            }


            echo json_encode($json);

?>
