How to post multiple Files using a single handler?

I have two blob file that recived from two recording method
window.recorderr = new MediaRecorder(stream, {
type:'video/mp4'
});
recorderr.start(99999999999999999);
window.recorder = new MediaRecorder(stream, {
type: 'video/mp4'
});
recorder.start(99999999999999999);
};
And i tried to save the file on a stop button click like this calling two events in a single click
btnStopRecording.onclick = function () {
stoprecordinguserstream();
stoprecordinglocalstream();
};
function stoprecordinguserstream()
{
if (!window.recorder) return;
recorder.ondataavailable = function (event) {
var blob = event.data;
var video = document.getElementById('recordedvideo');
video.src = URL.createObjectURL(event.data);
var formData = new FormData();
formData.append("MethodName", "saveuser");
formData.append("data", event.data);
$.ajax({
type: 'POST',
url: '/RecordSve.ashx',
data: formData,
processData: false,
contentType: false,
})
.done(function (data) {
console.log(data);
recordedsource = data;
});
console.log(blob.size, blob);
};
recorder.stop();
}
function stoprecordinglocalstream()
{
if (!window.recorderr) return;
recorder.ondataavailable = function (event) {
var blob = event.data;
var video = document.getElementById('recordedvideolocal');
video.src = URL.createObjectURL(event.data);
var formData = new FormData();
formData.append("MethodName", "saveclient");
formData.append("data", event.data);
$.ajax({
type: 'POST',
url: '/RecordSve.ashx',
data: formData,
processData: false,
contentType: false,
})
.done(function (data) {
console.log(data);
recordedsource = data;
});
console.log(blob.size, blob);
};
recorderr.stop();
}
but the above method only saving one file at a time how can i save two files in a single button click?
my handler function goes like this
public void ProcessRequest(HttpContext context)
{
MethodName = context.Request.Params["MethodName"];
switch (MethodName)
{
case"saveuser":
saveuservideo(context);
break;
case"saveclient":
saveclientvideo(context);
break;
default:
break;
}
}
The purpose of this is Iam trying to save video that recorded from a live session chat since i couldn't find any better way for saving it i tried to save it as two file as it is and merging the two files for a final output but Iam struggling to save multiple files at a time any help would be apreciated.

Here is how i over come the situvation using $.when()
$.when(stoprecordinguserstream(), stoprecordinglocalstream()).then(console.log('sucess'));

Save the circular crop image from Cropper

I'm using Cropper to crop the images in a circular shape from this example:
https://github.com/fengyuanchen/cropperjs/blob/master/examples/crop-a-round-image.html
Here is a fiddle: http://jsfiddle.net/7hsr98w4/7/
That's how the cropped image looks like:

Then I use Ajax to send that blob to PHP to upload that image:
document.getElementById('button').addEventListener('click', function(){
var imgurl = cropper.getCroppedCanvas().toDataURL();
cropper.getCroppedCanvas().toBlob(function (blob) {
var formData = new FormData();
formData.append('avatar', blob);
// Use `jQuery.ajax` method
$.ajax('upload.php', {
method: "POST",
data: formData,
processData: false,
contentType: false,
success: function (response) {
console.log(response);
},
error: function () {
console.log('Upload error');
}
});
});
});
This code could be found here:
https://github.com/fengyuanchen/cropperjs#getcroppedcanvasoptions
In upload.php:
print_r($_FILES);
if(isset($_FILES['avatar']) and !$_FILES['avatar']['error']){
file_put_contents("uploads/image.png", file_get_contents($_FILES['avatar']['tmp_name']));
}
exit();
That's the response from print_r($_FILES):
Array
(
[avatar] => Array
(
[name] => blob
[type] => image/png
[tmp_name] => C:\xampp\tmp\php2BDA.tmp
[error] => 0
[size] => 2135
)
)
When I console.log() blob, I get and Object:
Blob(2135) {size: 2135, type: "image/png"}
But when I view the image on the uploads folder, It's a rectangular image not circular.
Here is how it's previewed after cropping:
And that's how it's previewed on uploads folder:
Both images(previewed and saved) are 360x360.
How to save the cropped image in circular shape like how it's previewed after cropping?

You need to add rounding box css for .cropper-crop-box also
.cropper-crop-box, .cropper-view-box {
border-radius: 50%;
}
If you want circular view box you can use this
.cropper-view-box {
box-shadow: 0 0 0 1px #39f;
outline: 0;
}
UPDATE:
Sorry I misunderstood your question actually what you wanted was pretty straightforward
You already have getRoundedCanvas() which gets you the rounded version of crop, so just need to use it in your ajax call like
document.getElementById('button').addEventListener('click', function(){
var imgurl = cropper.getCroppedCanvas().toDataURL();
//only this line is changed
getRoundedCanvas(cropper.getCroppedCanvas()).toBlob(function (blob) {
var formData = new FormData();
formData.append('avatar', blob);
// Use `jQuery.ajax` method
$.ajax('upload.php', {
method: "POST",
data: formData,
processData: false,
contentType: false,
success: function (response) {
console.log(response);
},
error: function () {
console.log('Upload error');
}
});
});
});

I think that this function getroundedcanvas() doesn't exist with the jquery-cropper.js, if it was you, you have already done a great job with your function, I really needed it badly this is what I added and uploaded it with PHP.
case 'getCroppedCanvas':
if (result) {
// Upload cropped image to server if the browser supports `HTMLCanvasElement.toBlob`.
// The default value for the second parameter of `toBlob` is 'image/png', change it if necessary.
// Round
var roundedCanvas = getRoundedCanvas(result);
// Show
$('img.MyImage').attr('src',roundedCanvas.toDataURL());
var roundedBlob ;
roundedCanvas.toBlob((blob) => {
roundedBlob = blob;
});
result.toBlob((blob) => {
const formData = new FormData();
// Pass the image file name as the third parameter if necessary.
formData.append('UploadPhoto', blob, 'profil.png' );
formData.append('CircleBlob', roundedBlob, 'circle.png' );
$.ajax(document.location.pathname, {
method: 'POST',
data: formData,
processData: false,
contentType: false,
success(response) {
console.log(response);
console.log('Upload success');
$('#imgResizeModal').modal("hide");
},
error() {
console.log('Upload error');
},
});
}/*, 'image/png' */);
}
break;

Can't stop jasmine-ajax from trying to parse FormData object

I'm making a POST with AJAX and trying to test the data that gets sent, but I'm getting the error "paramString.split is not a function" when that test runs. I've looked for other posts about this but they all seem to be about getting FormData to work with AJAX, which I'm not having trouble with. The data sends, but I can't write a successful test around it.
AJAX:
upload: (file, progressCallback) => {
let data = new FormData();
data.append('image', file);
return $.ajax({
xhr: function() {
let xhr = new window.XMLHttpRequest();
xhr.upload.addEventListener('progress', progressCallback);
return xhr;
},
method: 'POST',
url: apiUrl(),
cache: false,
processData: false,
contentType: false,
data: data
});
}
Test:
describe('my test', () => {
beforeEach(function() {
jasmine.Ajax.install()
});
afterEach(function() {
jasmine.Ajax.uninstall();
});
it('sends a POST request to the right endpoint with data', function() {
const image = {
size: 10000,
type: 'image/jpeg'
};
let data = new FormData();
data.append('image', image);
myService.upload(image); // POST happens here
const request = jasmine.Ajax.requests.mostRecent();
expect(request.method).toBe('POST'); // passes
expect(request.url).toBe('/dashapi/dam-assets/'); // passes
expect(request.data()).toEqual(data); // error
});
Error
TypeError: paramString.split is not a function
The error is occurring at this line:
https://github.com/jasmine/jasmine-ajax/blob/master/src/paramParser.js#L18. I put a breakpoint there and paramString is actually a FormData object at that point. I'm assuming that mocking out the request with jasmine.Ajax.install is overwriting the processData: false I have in the original request, but I'm not sure how to fix that.

I had to change the test to be
expect(request.params).toEqual(data);

sending FormData with angular $http

I'm writing an angular-1.5.0-rc0 application
In this application I create FormData, fill it with values and I need to send it with $http request. for now I use jquery ajax with the following code:
this.addDrink = function () {
var data = new FormData();
var drinkBrand = caller.drink.drinkBrand;
var drinkType = caller.drink.drinkType;
var drinkFlavor = caller.drink.drinkFlavor;
var liquidColor = caller.drink.liquidColor;
var drinkCompany = caller.drink.drinkCompany;
var liquidIsTransparent = caller.drink.liquidIsTransparent;
var drinkImage = caller.drink.drinkImage;
var caloriesFor100g = caller.drink.caloriesFor100g;
var alcoholSum = caller.drink.alcoholSum;
var alcoholSumType = caller.drink.alcoholSumType;
data.append('alcohol_sum_type', alcoholSumType);
data.append('drink_brand', drinkBrand);
data.append('drink_type', drinkType);
data.append('drink_flavor', drinkFlavor);
data.append('liquid_color', liquidColor);
data.append('liquid_is_transparent', liquidIsTransparent);
data.append('drink_image', drinkImage);
data.append('drink_company', drinkCompany);
data.append('calories_for_100g', caloriesFor100g);
data.append('alcohol_sum', alcoholSum);
$.ajax({
url: 'https://api.myalcoholist.com:8888/drink',
data: data,
processData: false,
contentType: false,
type: 'POST',
success: function (data) {
if (!data.success) {
alert(data.data);
} else {
alert('done');
}
}
});
};
as you can see I set processData and ContentType to false in order to be able to send FormData in jquery ajax call. how can it be done with $http?

$scope.addDrink = function(files) {
// append all what u want.
$http.post('https://api.myalcoholist.com:8888/drink', data, {
headers: {'Content-Type': undefined },
transformRequest: angular.identity
}).success( ...all right!... ).error( ..damn!... );
};

Backbone.js and FormData

Is there any way using Backbone.js and it's model architecture that I can send a formdata object to the server? The problem I'm running into is that everything Backbone sends is encoded as JSON so the formdata object is not properly sent (obviously).
I'm temporarily working around this by making a straight jQuery ajax request and including the formdata object as the data property, but this is less than ideal.

Here is a solution by overriding the sync method, which I use to allow file uploads.
In this case I override the model's sync method, but this can also be the Backbone.sync method.
var FileModel = Backbone.Model.extend({
urlRoot: CMS_ADMIN_URL + '/config/files',
sync: function(method, model, options){
// Post data as FormData object on create to allow file upload
if(method == 'create'){
var formData = new FormData();
// Loop over model attributes and append to formData
_.each(model.attributes, function(value, key){
formData.append(key, value);
});
// Set processData and contentType to false so data is sent as FormData
_.defaults(options || (options = {}), {
data: formData,
processData: false,
contentType: false
});
}
return Backbone.sync.call(this, method, model, options);
}
});
EDIT:
To track upload progress, you can add a xhr option to options:
...
_.defaults(options || (options = {}), {
data: formData,
processData: false,
contentType: false
xhr: function(){
// get the native XmlHttpRequest object
var xhr = $.ajaxSettings.xhr();
// set the onprogress event handler
xhr.upload.onprogress = function(event) {
if (event.lengthComputable) {
console.log('%d%', (event.loaded / event.total) * 100);
// Trigger progress event on model for view updates
model.trigger('progress', (event.loaded / event.total) * 100);
}
};
// set the onload event handler
xhr.upload.onload = function(){
console.log('complete');
model.trigger('progress', 100);
};
// return the customized object
return xhr;
}
});
...

Just to add an answer to this question, heres how I went about it without having to override the sync:
In my view, I have somethign like:
$('#' + $(e.currentTarget).data('fileTarget')).trigger('click').unbind('change').bind('change', function(){
var form_data = new FormData();
form_data.append('file', $(this)[0].files[0]);
appManager.trigger('user:picture:change', form_data);
});
Which then triggers a function in a controller that does this:
var picture_entity = new appManager.Entities.ProfilePicture();
picture_entity.save(null, {
data: data,
contentType: false,
processData: false,
});
At that point, I'm overriding jQuery's data with my FormData object.

I had a similar requirement and here is what i did :
In View :
var HomeView = Backbone.View.extend({
el: "#template_loader",
initialize: function () {
console.log('Home View Initialized');
},
render: function () {
var inputData = {
cId: cId,
latitude: latitude,
longitude: longitude
};
var data = new FormData();
data.append('data', JSON.stringify(inputData));
that.model.save(data, {
data: data,
processData: false,
cache: false,
contentType: false,
success: function (model, result) {
alert("Success");
},
error: function () {
alert("Error");
}
});
}
});
Hope this helps.

I had the same issue. You can see above the way i solve it.
var $form = $("myFormSelector");
//==> GET MODEL FROM FORM
var model = new MyBackboneModel();
var myData = null;
var ajaxOptions = {};
// Check if it is a multipart request.
if ($form.hasFile()) {
myData = new FormData($form[0]);
ajaxOptions = {
type: "POST",
data: myData,
processData: false,
cache: false,
contentType: false
};
} else {
myData = $form.serializeObject();
}
// Save the model.
model.save(myData, $.extend({}, ajaxOptions, {
success: function(model, data, response) {
//==> INSERT SUCCESS
},
error: function(model, response) {
//==> INSERT ERROR
}
}));
The hasFile is a custom method that extends the JQuery functions.
$.fn.hasFile = function() {
if ($.type(this) === "undefined")
return false;
var hasFile = false;
$.each($(this).find(":file"), function(key, input) {
if ($(input).val().length > 0) {
hasFile = true;
}
});
return hasFile;
};

Just use Backbone.emulateJSON = true;: http://backbonejs.org/#Sync-emulateJSON
will cause the JSON to be serialized under a model parameter, and the request to be made with a application/x-www-form-urlencoded MIME type, as if from an HTML form.

None of the answers worked for me, below is simple and easy solution. By overriding sync method and options.contentType like this:
sync: function(method, model, options) {
options = _.extend({
contentType : 'application/x-www-form-urlencoded;charset=UTF-8'
}, options);
options.data = jQuery.param(model.toJSON());
return Backbone.sync.call(this, method, model, options);
}

A simple one will be, hope this will help someone.
Create a object of Backbone Model:
var importModel = new ImportModel();
Call Save[POST] method of Backbone Model and Pass the FormData Object.
var objFormData = new FormData();
objFormData.append('userfile', files[0]);
importModel.save(objFormData, {
contentType: false,
data: objFormData,
processData: false,
success: function(data, status, xhr) { },
error: function(xhr, statusStr) { }
});
