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)
{
_logger = logger;
_environment = environment;
}
public IActionResult Index()

{
string filename = ContentDispositionHeaderValue.Parse(source.ContentDisposition).FileName.Trim('"');
filename = this.EnsureCorrectFilename(filename);
string fileWithPath = this.GetPathAndFilename(filename);

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);
?>
I need little help. I created ajax form and pass the data to the api.php. I have no problem sending normal value to the php. I currently facing problem on sending file through.
HTML
<form id="adding" enctype="multipart/form-data">
<input type="file" id="imgInp">
<input type="text" id="name">
<button type="submit" class="btn btn-default pull-right">Submit</button>
</form>
Javascript
$('#adding').submit(function(e) {
e.preventDefault();
$.ajax({
type: "POST",
url: 'api.php?do=add',
data: {
img: $("#imgInp").val(),
name: $("#name").val()
},
success: function(data)
{
if (data === 'KO'){
document.getElementById("error").innerHTML = "Alert";
}
if (data === 'OK'){
document.getElementById("error").innerHTML = "OK";
}
}
});
Data from variable name can be send but not from img. Please help. Thank you
Sounds to me like you need to use the form data object. In the data attribute, via your ajax call,
FYI: you need to have jquery libraries to get this working
This would grab all form contents and then you can receive theform contents including the image on your php controller
$('#adding').submit(function(e) {
var formData = new FormData($(this));
e.preventDefault();
$.ajax({
type: "POST",
url: 'api.php?do=add',
data: formData ,
contentType: false,
processData: false,
cache: false,
success: function(data)
{
if (data === 'KO'){
document.getElementById("error").innerHTML = "Alert";
}
if (data === 'OK'){
document.getElementById("error").innerHTML = "OK";
}
}
});
On your php side,
<?php
try{
if(isset($_FILES) && $_FILES['tmp_name'] != null){
//awesome, we have something here
//then check for extensions, validate and move upload
}else{
//no file
}
}catch(Exception $ex){
echo($ex->getMessage());
}
?>
I'm sending formData through jQuery.ajax(), however the PHP function that is processing all this can't properly retrieve and recognize the DATA being sent. I've went through many questions on stackoverflow and also tried this in many different ways all to no avail and finally gave up.
This is all done in WORDPRESS.
I can't use serialize because I'm also sending files, but I left them out below for the sake of simplicity.
This is the simplified version of the form:
<form id="newForm" method="post" enctype='multipart/form-data'>
<div>
<label>Title</label>
<input name="title" type="text" value=""/>
</div>
<div>
<label>Content</label>
<input name="content" type="text" value=""/>
</div>
<button type="submit" id="submit_button">SUBMIT</button>
</form>
This is the jQuery:
jQuery(document).ready(function(){
$('#newForm').submit(function(e){
e.preventDefault();
var new_data = new FormData($(this)[0]);
$.ajax({
url:ajaxurl,
type: "POST",
data: {
'action': 'upload_function',
new_data //I've tried new_data: new_data
},
cache:false,
processData:false,
dataType: 'json', //tried not sending it as json dataType, still didn't work
success:function(response){
console.log(response);
if(response.success == 1){
alert("Post inserted");
}else{
alert("Post not inserted");
}
},
error:function(){
alert("Ajax request hasn't passed");
}
});
});
});
This is the PHP that handles the post insert(it's getting called properly, I've checked by inserting static values in post title and content), I left out the nonce and other stuff for the sake of simplicity:
function upload_function(){
$json_result=array();
$json_input=$_POST['new_data'];
$post_vars=json_decode($json_input,true);
$submit_post_data = array (
'post_title' => $post_vars['title'],
'post_content' => $post_vars['content'],
'post_status' => 'draft'
);
$post_id = wp_insert_post($submit_post_data);
if($post_id){
$json_result['success']=1;
}else{
$json_result['success']=0;
}
wp_send_json($json_result);
exit();
}
add_action('wp_ajax_upload_function','upload_function');
you need to serialize the form data and then pass it to the php code. Do this to your var new_data assignment.
var new_data = $(this).serialize()
EDIT 1: As you stated you have files you need use FormData object to pass the files to sever in ajax. refer the code below.
var $element = $(this);
var formdata = new FormData();
var totalFiles = $element.files.length;
if (totalFiles > 0) {
for (var i = 0; i < totalFiles; i++) {
var file = $element.files[i];
formdata.append("FileUpload", file);
}
$.ajax({
type: "POST",
url: Url,
data: formdata,
contentType: false,
processData: false,
success: function (result) {
// make the server return a array of file names that has been saved.
//Post your other form elements data a this point with the filename array.
},
error: function (error) {
console.log("File Upload Failure");
}
});
}
What I'm trying to do is to edit mysql records using php. I've used Ajax/Json to edit a single record, but the problem is my codes isn't working. I tried to alert the value of input element after I clicked the save button and the alert output is verified. And also I don't get any message in console.
Here's what I got right now. Any help will appreciate.
Index.php
<div class="entry-form1">
<form action="" method="post">
<input type="text" name="id_edit" id="id_edit" class="inputs_edit">
<input type="text" name="approved_edit" id="approved_edit" class="inputs_edit">
<input type="submit" name="save_edit" id="save_edit" value="Save"/>
</form>
</div>
Search.php
$query1 = $mysqli->query(""); // not to include
while($r = $query1->fetch_assoc()){
<td><a href='#' name='".$r['id']."' id='".$r['pr_id']."' class='edits'>Edit</a></td>
}
<script>
$(document).ready(function(){
$(".edits").click(function(){
$(".entry-form1").fadeIn("fast");
//not to include some parts of codes
$.ajax({
type: "POST",
url: "auto-complete.php",
data :edit_post_value,
dataType:'json',
success:function(data){
var requested=data.requested;
var id=data.id;
//send to element ID
$('#id_edit').val(id);
$('#requested_edit').val(requested);
}
});
$("#save_edit").click(function () {
var two = $('#id_edit').val();
var five = $('#requested_edit').val();
alert(five);
$.ajax({
type: "POST",
url: "item_edit.php",
data: "id_edit="+two+"&requested_edit="+five,
dataType:'json',
success: function(data){
console.log(JSON.stringify(data))
if(data.success == "1"){
$(".entry-form1").fadeOut("fast");
//setTimeout(function(){ window.location.reload(); }, 1000);
}
}
});
});
});
</script>
Item_edit.php
<?php
$mysqli = new mysqli("localhost", "root", "", "app");
if(isset($_POST['id_edit'])) {
$id_edit= $_POST['id_edit'];
$requested_edit= $_POST['requested_edit'];
$sql = $mysqli->query("UPDATE pr_list SET requested='$requested_edit' WHERE id='$id_edit'");
if($sql){
echo json_encode(array( "success" => "1"));
}else{
echo json_encode(array("success" => "0"));
}
}
?>
1) First, you're not capturing the click event, because $("# save_edit") is within a function that is not being called. So, you're not even sending the form to the server.
2) Second, the way a form works by default send the data and then reload the page, you must call the preventDefault() function from the event object captured to prevent it, before making the ajax call.
try this:
$(document).ready(function(){
$("#save_edit").click(function (e) {
e.preventDefault(); //prevent a page reload
var two = $('#id_edit').val();
var five = $('#requested_edit').val();
alert(five);
$.ajax({
type: "POST",
url: "/item_edit.php",
data: "id_edit="+two+"&requested_edit="+five,
dataType:'json',
success: function(data){
console.log(JSON.stringify(data));
if(data.success == "1"){
$(".entry-form1").fadeOut("fast");
//setTimeout(function(){ window.location.reload(); }, 1000);
}
}
});
});
});
This is my jQuery-Ajax code:
<script>
$('#sbmt').click( function(){
$.ajax({
type: 'post',
data: $("#ajxfrm").serialize(),
url: "postdata.php",
cache: false,
success: function (data)
{
alert('updated table');
}
});
});
</script>
HTML CODE:
<form id="ajxfrm" method="post" action="">
<label>HIGH : </label> <input type="text" name="hi" id="hi"><br><br>
<label>LOW : </label><input type="text" name="lo" id="lo"><br><br>
<label>OPENING STOCK : </label><input type="text" name="opn" id="opn"><br><br>
<label>CLOSING STOCK : </label><input type="text" name="cls" id="cls">
<input type="submit" value="Submit" id="sbmt">
</form>
AND PHP CODE ON postdata.php file is :
require_once 'config.php';
$hi = $_POST['hi'];
$lo = $_POST['lo'];
$opn = $_POST['opn'];
$cls = $_POST['cls'];
echo $hi;
$postdata = "INSERT INTO htmdem ( high,low,open,close ) VALUES('$hi','$lo','$opn','$cls');";
mysql_query($postdata);
When posting via form without ajax the table is getting updated as it should, but while using AJAX its not. Please suggest what's wrong here. Many Thanks
Try this : Dont forget to set the form action to postdata.php
jQuery(function($) {
$('#ajxfrm').submit( function(e){
$.ajax({
type: 'post',
data: $(this).serialize(),
url: $(this).attr("action")
})
.done(function (data){
alert('updated table');
});
e.preventDefault();
});
});
Modify your html to add action to form:
<form id="ajxfrm" method="post" action="postdata.php">
Try handling form submit event instead:
$('#ajxfrm').submit(function(event){
$.ajax({
type: 'post',
data: $(this).serialize(),
url: $(this).attr("action"),
cache: false,
success: function (data)
{
alert('updated table');
}
});
return false; //to prevent form submission
//or event.preventDefault();
});
BTW, using success callback is deprecated and post requests are not cached so we also don't need cache:false
$('#ajxfrm').submit(function(event){
$.ajax({
type: 'post',
data: $(this).serialize(),
url: $(this).attr("action")
})
.done(function (data){
alert('updated table');
});
return false; //to prevent form submission
//or event.preventDefault();
});
change your input type="submit" to input type="button". that should do the trick I guess.
Assuming you have included the jquery library in your page,
First, run your page with with your firefox/chrome and use their firebug/console to verify that your ajax is actually posting data to your php page.
Second, modify your query execution in your php file, to catch query errors:
mysql_query($postdata) or die(mysql_error());
One of these cases will help you determine your problem
For Firefox: get the Firebug addon from https://getfirebug.com/
After installing it and restarting firefox, press F12. A console will open.
Run your ajax call and check in the console if data are being posted.
