I have a file in my view
<form id="upload" enctype="multipart/form-data">
<input type="file" name="fileUpload" id="fileUpload" size="23" />
</form>
and an ajax request
$.ajax({
url: '<%=Url.Action("JsonSave","Survey") %>',
dataType: 'json',
processData: false,
contentType: "multipart/mixed",
data: {
Id: selectedRow.Id,
Value: 'some date was added by the user here :))'
},
cache: false,
success: function (data) {}
});
but there is no file in the Request.Files. Whats wrong with the ajax request?
Upload files using AJAX in ASP.Net MVC
Things have changed since HTML5
JavaScript
document.getElementById('uploader').onsubmit = function () {
var formdata = new FormData(); //FormData object
var fileInput = document.getElementById('fileInput');
//Iterating through each files selected in fileInput
for (i = 0; i < fileInput.files.length; i++) {
//Appending each file to FormData object
formdata.append(fileInput.files[i].name, fileInput.files[i]);
}

public JsonResult Upload()
{
for (int i = 0; i < Request.Files.Count; i++)
{

//To save file, use SaveAs method
file.SaveAs(Server.MapPath("~/")+ fileName ); //File will be saved in application root

}
EDIT : The HTML
<form id="uploader">
<input id="fileInput" type="file" multiple>

</form>
AJAX file uploads are now possible by passing a FormData object to the data property of the $.ajax request.
As the OP specifically asked for a jQuery implementation, here you go:
<form id="upload" enctype="multipart/form-data" action="#Url.Action("JsonSave", "Survey")" method="POST">
<input type="file" name="fileUpload" id="fileUpload" size="23" /><br />
<button>Upload!</button>
</form>
$('#upload').submit(function(e) {
e.preventDefault(); // stop the standard form submission
$.ajax({
url: this.action,
type: this.method,
data: new FormData(this),
cache: false,
contentType: false,
processData: false,
success: function (data) {
console.log(data.UploadedFileCount + ' file(s) uploaded successfully');
},
error: function(xhr, error, status) {
console.log(error, status);
}
});
});
public JsonResult Survey()
{
for (int i = 0; i < Request.Files.Count; i++)
{
var file = Request.Files[i];
// save file as required here...
}
return Json(new { UploadedFileCount = Request.Files.Count });
}

You can't upload files via ajax, you need to use an iFrame or some other trickery to do a full postback. This is mainly due to security concerns.
Here's a decent write-up including a sample project using SWFUpload and ASP.Net MVC by Steve Sanderson. It's the first thing I read getting this working properly with Asp.Net MVC (I was new to MVC at the time as well), hopefully it's as helpful for you.
I have a sample like this on vuejs version: v2.5.2
<form action="url" method="post" enctype="multipart/form-data">
<div class="col-md-6">
<input type="file" class="image_0" name="FilesFront" ref="FilesFront" />
</div>
<div class="col-md-6">
<input type="file" class="image_1" name="FilesBack" ref="FilesBack" />
</div>
</form>

};
},

event.preventDefault();
var data = new FormData();
var _doc = this.document;
Object.keys(_doc).forEach(function (key) {

var _refs = this.$refs;
Object.keys(_refs).forEach(function (key) {

If you posting form using ajax then you can not
send image using $.ajax method,
you have to use classic xmlHttpobject method for saving image,
other alternative of it use submit type instead of button

I'm using jQuery and Ajax for my forms to submit data and files but I'm not sure how to send both data and files in one form?
I currently do almost the same with both methods but the way in which the data is gathered into an array is different, the data uses .serialize(); but the files use = new FormData($(this)[0]);
Is it possible to combine both methods to be able to upload files and data in one form through Ajax?
Data jQuery, Ajax and html
$("form#data").submit(function(){
var formData = $(this).serialize();
$.ajax({
url: window.location.pathname,
type: 'POST',
data: formData,
async: false,
success: function (data) {
alert(data)
},
cache: false,
contentType: false,
processData: false
});
return false;
});
<form id="data" method="post">
<input type="text" name="first" value="Bob" />
<input type="text" name="middle" value="James" />
<input type="text" name="last" value="Smith" />
<button>Submit</button>
</form>
Files jQuery, Ajax and html
$("form#files").submit(function(){
var formData = new FormData($(this)[0]);
$.ajax({
url: window.location.pathname,
type: 'POST',
data: formData,
async: false,
success: function (data) {
alert(data)
},
cache: false,
contentType: false,
processData: false
});
return false;
});
<form id="files" method="post" enctype="multipart/form-data">
<input name="image" type="file" />
<button>Submit</button>
</form>
How can I combine the above so that I can send data and files in one form via Ajax?
My aim is to be able to send all of this form in one post with Ajax, is it possible?
<form id="datafiles" method="post" enctype="multipart/form-data">
<input type="text" name="first" value="Bob" />
<input type="text" name="middle" value="James" />
<input type="text" name="last" value="Smith" />
<input name="image" type="file" />
<button>Submit</button>
</form>
The problem I had was using the wrong jQuery identifier.
You can upload data and files with one form using ajax.
PHP + HTML
<?php
print_r($_POST);
print_r($_FILES);
?>
<form id="data" method="post" enctype="multipart/form-data">
<input type="text" name="first" value="Bob" />
<input type="text" name="middle" value="James" />
<input type="text" name="last" value="Smith" />
<input name="image" type="file" />
<button>Submit</button>
</form>
jQuery + Ajax
$("form#data").submit(function(e) {
e.preventDefault();
var formData = new FormData(this);
$.ajax({
url: window.location.pathname,
type: 'POST',
data: formData,
success: function (data) {
alert(data)
},
cache: false,
contentType: false,
processData: false
});
});
Short Version
$("form#data").submit(function(e) {
e.preventDefault();
var formData = new FormData(this);
$.post($(this).attr("action"), formData, function(data) {
alert(data);
});
});
another option is to use an iframe and set the form's target to it.
you may try this (it uses jQuery):
function ajax_form($form, on_complete)
{
var iframe;
if (!$form.attr('target'))
{
//create a unique iframe for the form
iframe = $("<iframe></iframe>").attr('name', 'ajax_form_' + Math.floor(Math.random() * 999999)).hide().appendTo($('body'));
$form.attr('target', iframe.attr('name'));
}
if (on_complete)
{
iframe = iframe || $('iframe[name="' + $form.attr('target') + '"]');
iframe.load(function ()
{
//get the server response
var response = iframe.contents().find('body').text();
on_complete(response);
});
}
}
it works well with all browsers, you don't need to serialize or prepare the data.
one down side is that you can't monitor the progress.
also, at least for chrome, the request will not appear in the "xhr" tab of the developer tools but under "doc"
I was having this same issue in ASP.Net MVC with HttpPostedFilebase and instead of using form on Submit I needed to use button on click where I needed to do some stuff and then if all OK the submit form so here is how I got it working
$(".submitbtn").on("click", function(e) {
var form = $("#Form");
// you can't pass Jquery form it has to be javascript form object
var formData = new FormData(form[0]);
//if you only need to upload files then
//Grab the File upload control and append each file manually to FormData
//var files = form.find("#fileupload")[0].files;
//$.each(files, function() {
// var file = $(this);
// formData.append(file[0].name, file[0]);
//});
if ($(form).valid()) {
$.ajax({
type: "POST",
url: $(form).prop("action"),
//dataType: 'json', //not sure but works for me without this
data: formData,
contentType: false, //this is requireded please see answers above
processData: false, //this is requireded please see answers above
//cache: false, //not sure but works for me without this
error : ErrorHandler,
success : successHandler
});
}
});
this will than correctly populate your MVC model, please make sure in your Model, The Property for HttpPostedFileBase[] has the same name as the Name of the input control in html i.e.
<input id="fileupload" type="file" name="UploadedFiles" multiple>
public class MyViewModel
{
public HttpPostedFileBase[] UploadedFiles { get; set; }
}
Or shorter:
$("form#data").submit(function() {
var formData = new FormData(this);
$.post($(this).attr("action"), formData, function() {
// success
});
return false;
});
EDIT: with the new version of JQuery (3.6), you could also try using contentType function argument instead of enctype. Try contentType: multipart/form-data.
For me, it didn't work without enctype: 'multipart/form-data' field in the Ajax request. I hope it helps someone who is stuck in a similar problem.
Even though the enctype was already set in the form attribute, for some reason, the Ajax request didn't automatically identify the enctype without explicit declaration (jQuery 3.3.1).
// Tested, this works for me (jQuery 3.3.1)
fileUploadForm.submit(function (e) {
e.preventDefault();
$.ajax({
type: 'POST',
url: $(this).attr('action'),
enctype: 'multipart/form-data',
data: new FormData(this),
processData: false,
contentType: false,
success: function (data) {
console.log('Thank God it worked!');
}
}
);
});
// enctype field was set in the form but Ajax request didn't set it by default.
<form action="process/file-upload" enctype="multipart/form-data" method="post" >
<input type="file" name="input-file" accept="text/plain" required>
...
</form>
As others mentioned above, please also pay special attention to the contentType and processData fields.
A Simple but more effective way:
new FormData() is itself like a container (or a bag). You can put everything attr or file in itself.
The only thing you'll need to append the attribute, file, fileName eg:
let formData = new FormData()
formData.append('input', input.files[0], input.files[0].name)
and just pass it in AJAX request. Eg:
let formData = new FormData()
var d = $('#fileid')[0].files[0]
formData.append('fileid', d);
formData.append('inputname', value);
$.ajax({
url: '/yourroute',
method: 'POST',
contentType: false,
processData: false,
data: formData,
success: function(res){
console.log('successfully')
},
error: function(){
console.log('error')
}
})
You can append n number of files or data with FormData.
and if you're making AJAX Request from Script.js file to Route file in Node.js beware of using
req.body to access data (ie text)
req.files to access file (ie image, video etc)
The code below works for me
$(function () {
debugger;
document.getElementById("FormId").addEventListener("submit", function (e) {
debugger;
if (ValidDateFrom()) { // Check Validation
var form = e.target;
if (form.getAttribute("enctype") === "multipart/form-data") {
debugger;
if (form.dataset.ajax) {
e.preventDefault();
e.stopImmediatePropagation();
var xhr = new XMLHttpRequest();
xhr.open(form.method, form.action);
xhr.onreadystatechange = function (result) {
debugger;
if (xhr.readyState == 4 && xhr.status == 200) {
debugger;
var responseData = JSON.parse(xhr.responseText);
SuccessMethod(responseData); // Redirect to your Success method
}
};
xhr.send(new FormData(form));
}
}
}
}, true);
});
In your Action Post Method, pass parameter as HttpPostedFileBase UploadFile and make sure your file input has same as mentioned in your parameter of the Action Method.
It should work with AJAX Begin form as well.
Remember over here that your AJAX BEGIN Form will not work over here since you make your post call defined in the code mentioned above and you can reference your method in the code as per the Requirement
I know I am answering late but this is what worked for me
Just to remind, in 2022 you don't need to use jquery. Try js standard Fetch API
var formData = new FormData(this);
fetch(url, {
method: 'POST',
body: formData
})
.then(response => {
if(response.ok) {
//success
alert(response);
} else {
throw Error('Server error');
}
})
.catch(error => {
console.log('fail', error);
});
This is a solution that I implemented
var formData = new FormData();
var files = $('input[type=file]');
for (var i = 0; i < files.length; i++) {
if (files[i].value == "" || files[i].value == null) {
return false;
}
else {
formData.append(files[i].name, files[i].files[0]);
}
}
var formSerializeArray = $("#Form").serializeArray();
for (var i = 0; i < formSerializeArray.length; i++) {
formData.append(formSerializeArray[i].name, formSerializeArray[i].value)
}
$.ajax({
type: 'POST',
data: formData,
contentType: false,
processData: false,
cache: false,
url: '/Controller/Action',
success: function (response) {
if (response.Success == true) {
return true;
}
else {
return false;
}
},
error: function () {
return false;
},
failure: function () {
return false;
}
});
---Solution for DOT NET CORE MVC Implementation---
While looking at this question I though I should right .NET CORE implementation for this because the question is not specific to any backend language.
So guys here is the standalone implementation example.
Objective :- To submit form fields including files and how we can get data in a single model at backend
HTML Code / View Code - Views/Home/Index.cshtml
#{
ViewData["Title"] = "Home Page";
}
<input type="file" id="FileUpload1" multiple />
<div>
<label>Enter First Name :</label>
<input type="text" id="nameText" maxlength="50" />
</div>
<input type="button" id="btnUpload" value="Submit Form with Files" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script>
$(document).ready(function () {
$('#btnUpload').click(function () {
// Checking whether FormData is available in browser
if (window.FormData !== undefined) {
var fileUpload = $("#FileUpload1").get(0);
var files = fileUpload.files;
// Create FormData object
var fileData = new FormData();
// Looping over all files and add it to FormData object
for (var i = 0; i < files.length; i++) {
fileData.append("files", files[i]);
}
// Adding one more key to FormData object
fileData.append('FirstName', $("#nameText").val());
$.ajax({
url: '/Home/UploadFiles',
type: "POST",
contentType: false, // Not to set any content header
processData: false, // Not to process data
data: fileData,
success: function (result) {
alert(result);
},
error: function (err) {
alert(err.statusText);
}
});
} else {
alert("FormData is not supported.");
}
});
});
</script>
Backend Code / Controller action method Controllers/HomeController.cs
public class HomeController : Controller
{

public HomeController(ILogger<HomeController> logger, IWebHostEnvironment environment)
{

In my case I had to make a POST request, which had information sent through the header, and also a file sent using a FormData object.
I made it work using a combination of some of the answers here, so basically what ended up working was having this five lines in my Ajax request:
contentType: "application/octet-stream",
enctype: 'multipart/form-data',
contentType: false,
processData: false,
data: formData,
Where formData was a variable created like this:
var file = document.getElementById('uploadedFile').files[0];
var form = $('form')[0];
var formData = new FormData(form);
formData.append("File", file);
you can just append them on your formdata, add your files and datas in it.you can read this..
https://developer.mozilla.org/en-US/docs/Web/API/FormData/append
for better understanding. you can separately retrieve them $_FILES for your files and $_POST for your data.
<form id="form" method="post" action="otherpage.php" enctype="multipart/form-data">
<input type="text" name="first" value="Bob" />
<input type="text" name="middle" value="James" />
<input type="text" name="last" value="Smith" />
<input name="image" type="file" />
<button type='button' id='submit_btn'>Submit</button>
</form>
<script>
$(document).on("click", "#submit_btn", function (e) {
//Prevent Instant Click
e.preventDefault();
// Create an FormData object
var formData = $("#form").submit(function (e) {
return;
});
//formData[0] contain form data only
// You can directly make object via using form id but it require all ajax operation inside $("form").submit(<!-- Ajax Here -->)
var formData = new FormData(formData[0]);
$.ajax({
url: $('#form').attr('action'),
type: 'POST',
data: formData,
success: function (response) {
console.log(response);
},
contentType: false,
processData: false,
cache: false
});
return false;
});
</script>
///// otherpage.php
<?php
print_r($_FILES);
?>
Is this even possible? I have a webform with certain textboxes etc and a file upload element. I am trying to send the data to webmethod using .ajax() method.
It seems to me that it is not possible to send file content to the webmethod in this manner. I am not even able to hit the webmethod.
script type="text/javascript">
var btn;
var span;
$(document).ready(function (e) {
$('#btnsave').on('click', function (event) {
Submit();
event.preventDefault();
});
})
function Submit() {
$.ajax({
type: "POST",
url: "SupplierMst.aspx/RegisterSupplier",
data: "{'file' : " + btoa(document.getElementById("myFile").value) + ",'biddername':" + document.getElementById("txtsuppliername").value + "}",
async: true,
contentType: "application/json; charset=utf-8",
success: function (data, status) {
console.log("CallWM");
alert(data.d);
},
failure: function (data) {
alert(data.d);
},
error: function (data) {
alert(data.d);
}
});
}
</script>
HTML:
<input id="txtsuppliername" type="text" /><br />
<input type="file" id="myFile">
Code behind :
[WebMethod]
public static string RegisterSupplier(string file, string biddername)
{
// break point not hit
return "a";
}
I have been trying to find solution to this for hours now. Nobody seems to be able help me out on this. Is this even possible using this approch. If not how do I do it? Somebody suggested that I should try to submit entire form instead of passing individual values.
This can be done without any library, by using the JavaScript FileReader API. With it, modern browsers can read the content of the file using JavaScript once it has been selected by the user, and then you could proceed as you were doing (encoding it as a string, and sending it over to the server).
The code would be like this (using the one above as a reference):
// NEW CODE
// set up the FileReader and the variable that will hold the file's content
var reader = new FileReader();
var fileContent = "";
// when the file is passed to the FileReader, store its content in a variable

You can run the code above, select a file (use a plain text file for testing so it's readable), and check the console to see its content. Then the rest of the code would be the same (I made a slight change to fix the parameters in the AJAX call).
Notice that sending the file like this has limits: if you use the GET method, you'll have a shorter parameter size limit, and with POST it will depend on the server settings... but I guess that you had those limits even for a file.
First of all go to App_Start>>RouteConfig.cs>>settings.AutoRedirectMode = RedirectMode.Off; and then Just Replace your function by my code it will definitely work for you,
Good Luck..

success: function (data, status) {
console.log("CallWM");
alert(data.d);

alert(data.d);

I am trying to use jquery file upload with ember.js. What i am hoping to achieve is there is a file input and when user browse the picture and hit the upload button, the jquery file upload will upload the file and return with the location of the uploaded file then.. i will collect other data from the rest of the form and post the information using ember data, which will include the the image url and rest of the form data.
I cannot make it work, but the same code works with plain html file with php backend.
Here i have included non functional code in jsbin which include my template and app.js code

Here's a minimal component you can use:
// index.html
<script src="/vendor/jquery/jquery.js"></script>
<script src="/vendor/jquery-ui/ui/jquery-ui.js"></script>
<script src="/vendor/jquery-file-upload/js/jquery.iframe-transport.js"></script>/script>
<script src="/vendor/jquery-file-upload/js/jquery.fileupload.js"></script>
// components/file-upload.js
export default Ember.TextField.extend({
attributeBindings: ['name', 'data-url', 'multiple'],
tagName: "input",
type: 'file',
name: "file[]",
"data-url": function(){
return this.get("path");
}.property("path"),
multiple: true,
didInsertElement: function() {
this.$().fileupload();
}
});
// to use in your hbs template
{{file-upload path="pathToUploadTo"}}
Here's an upload button that I use in my application: It builds up an input button, and auto uploads on change.
{{view App.UploadButton groupBinding="model"}}
App.UploadButton = Ember.View.extend({
tagName: 'input',
attributeBindings: ['type'],
type: 'file',
originalText: 'Upload Finished Product',
uploadingText: 'Busy Uploading...',
newItemHandler: function (data) {
var store = this.get('controller.store');
store.push('item', data);
},
preUpload: function () {
var me = this.$(),
parent = me.closest('.fileupload-addbutton'),
upload = this.get('uploadingText');
parent.addClass('disabled');
me.css('cursor', 'default');
me.attr('disabled', 'disabled');
},
postUpload: function () {
var me = this.$(),
parent = me.closest('.fileupload-addbutton'),
form = parent.closest('#fake_form_for_reset')[0],
orig = this.get('originalText');
parent.removeClass('disabled');
me.css('cursor', 'pointer');
me.removeAttr('disabled');
form.reset();
},
change: function (e) {
var self = this;
var formData = new FormData();
// This is just CSS
this.preUpload();
formData.append('group_id', this.get('group.id'));
formData.append('file', this.$().get(0).files[0]);
$.ajax({
url: '/file_upload_handler/',
type: 'POST',
//Ajax events
success: function (data) { self.postUpload(); self.newItemHandler(data); },
error: function () { self.postUpload(); alert('Failure'); },
// Form data
data: formData,
//Options to tell jQuery not to process data or worry about content-type.
cache: false,
contentType: false,
processData: false
});
}
});
