Ok I am stumped, I have been able to successfully upload resized image/blob to server folder. The problem is that the image/blob upload is always called blob. Is there a way to change name on client side or should i do it on server PHP side?.
And if so can you please give me an example here is the 2 scripts I am using to municate with

client side Resize

<script>
function handleFiles(){
var dataurl = null;
var filesToUpload = document.getElementById('input').files;
var file = filesToUpload[0];

// Create an image
var img = document.createElement("img");
// Create a file reader
var reader = new FileReader();
// Set the image once loaded into file reader
reader.onload = function(e)
{
    img.src = e.target.result;

    img.onload = function () {
        var canvas = document.createElement("canvas");
        var ctx = canvas.getContext("2d");
        ctx.drawImage(img, 0, 0);

        var MAX_WIDTH = 200;
        var MAX_HEIGHT = 400;
        var width = img.width;
        var height = img.height;

        if (width > height) {
          if (width > MAX_WIDTH) {
            height *= MAX_WIDTH / width;
            width = MAX_WIDTH;
          }
        } else {

        dataurl = canvas.toDataURL("image/jpeg",.2);
        var blobBin = atob(dataurl.split(',')[1]);
        var array = [];
        for(var i = 0; i < blobBin.length; i++) {
        array.push(blobBin.charCodeAt(i));
        }
       var files = new Blob([new Uint8Array(array)], {type: 'image/jpg', name: ""});

• javascript
• php
• ajax

• Oh my that is some scary php code. Also, if you state is always called blob yet your first line of php code is $_FILES["image"][ "name" ], then... which exactly is it? name or blob. – Abela Commented Sep 25, 2016 at 16:37
• name in image folder is just blob – INOH Commented Sep 25, 2016 at 16:39
• while saving you can rename using rename(oldname,newname,context) – Cyclotron3x3 Commented Sep 25, 2016 at 16:41

You can set the name property of a File object passed to FormData at third parameter of FormData.append() function

var blob = new Blob([123], {
  type: "text/plain"
});
var data = new FormData();
// set `blob` name to `"file.txt"`
data.append("file", blob, "file.txt");

console.log(data.get("file"), data.get("file").name);
