node.js upload image from ipad with socketio-file-upload - node.js

Question

I'm writing an app in express.js / node.js
I have a form with an input type "file" for upload images.
I want my images directly uploaded, without user confirmation. And displayed on the user screen after cropped and stored into a directory.
To do that, I use the socketio-file-upload library.
It works great on a computer. I can upload my images and display them.
The problem is with Ipad (I haven't try Iphone yet)
On the web app, when I click on the "browse" button, I can choose an existing picture or take a picture. I try to take a picture and upload it but nothing hapens...
Here is the code of the server for upload :
io.of('/register').on('connection', function (socket) {
/***************FILE UPLOAD***********************/
// Make an instance of socketioFileUploadServer and listen on this socket:
var uploader = new socketioFileUploadServer();
uploader.dir = __dirname + '/client/tmp/markers';
uploader.listen(socket);
// Do something when a file is saved:
uploader.on('saved', function(event){
console.log('Original saved');
// resize and rename image with a unique id
var newName = Math.random().toString(36).substr(2, 9);
// marker 32x32
easyimg.rescrop({src:path.resolve(__dirname, 'client/tmp/markers/' + event.file.name), dst:path.resolve(__dirname, 'client/tmp/markers/' + newName + '_marker'), width:32, height:32}, function(err, image) {
if (err) throw err;
console.log('Resized and cropped: ' + image.width + ' x ' + image.height);
// marker is uploaded - resized - croped, now display it
socket.emit('displayMarker', {markerPath : '/tmp/markers/' + newName + '_marker', markerName : newName});
// remove original from file system
fs.unlink(path.resolve(__dirname, 'client/tmp/markers/' + event.file.name), function(){
if (err) throw err;
console.log('Original removed');
});
});
});
uploader.on('start', function(event){
console.log('Client start upload');
socket.emit('displayOverlay');
});
// Error handler:
uploader.on('error', function(event){
console.log("Error from uploader", event);
});
});
And client side :
document.addEventListener("DOMContentLoaded", function(){
// REGISTRATION MARKER
var socketMarker = io.connect('/register');
var siofuMarker = new SocketIOFileUpload(socketMarker);
siofuMarker.listenOnInput(document.getElementById("uploadMarkerFromExploratorInput"));
// Do something when a file is uploaded:
siofuMarker.addEventListener("complete", function(event){
$('.overlay').hide();
});
// display loader window
socketMarker.on('displayOverlay', displayOverlay);
// server send we can display the marker in the register step1 view
socketMarker.on('displayMarker', function(data) {
$('#markerImage').html('');
$('#markerImage').html('<img src="' + data.markerPath + '" />');
$('#markerImageName').val(data.markerName);
});
});
With a computer, console will display :
Client start upload
Original saved
Resized and cropped: 32 x 32
Original removed
And with Ipad :
Client start upload
Is someone have a idea or another way to have the same result ?
Apreciate your help. C.

As I suspected, you need to add the proper attributes to the HTML markup for the File Input element:
<input type="file" accept="image/*" capture="camera">
That should do the trick. The most important part to understand is the "accepts" attribute.
