var fd = new FormData();
fd.append("fileToUpload", document.getElementById('fileToUpload').files[0]);
var xhr = new XMLHttpRequest();
xhr.open("POST", "uph.php");
xhr.send(fd);
uph.php:
var_dump($_FILES['fileToUpload']);
This works, but obviously for the files[0] only. How to get this working for chosen file?
I tried removing the [0], but it didn't work.
You have to get the files length to append in JS and then send it via AJAX request as below
//JavaScript
var ins = document.getElementById('fileToUpload').files.length;
for (var x = 0; x < ins; x++) {
fd.append("fileToUpload[]", document.getElementById('fileToUpload').files[x]);
}
//PHP
$count = count($_FILES['fileToUpload']['name']);
for ($i = 0; $i < $count; $i++) {
echo 'Name: '.$_FILES['fileToUpload']['name'][$i].'<br/>';
}
The way to go with javascript:
var data = new FormData();
$.each($("input[type='file']")[0].files, function(i, file) {
data.append('file', file);
});
$.ajax({
type: 'POST',
url: '/your/url',
cache: false,
contentType: false,
processData: false,
data : data,
success: function(result){
console.log(result);
},
error: function(err){
console.log(err);
}
})
If you call data.append('file', file) multiple times your request will contain an array of your files.
From MDN web docs:
"The append() method of the FormData interface appends a new value onto an existing key inside a FormData object, or adds the key if it does not already exist.
The difference between FormData.set and append() is that if the specified key already exists, FormData.set will overwrite all existing values with the new one, whereas append() will append the new value onto the end of the existing set of values."
Myself using node.js and multipart handler middleware multer get the data as follows:
router.post('/trip/save', upload.array('file', 10), function(req, res){
// Your array of files is in req.files
}
You just have to use fileToUpload[] instead of fileToUpload :
fd.append("fileToUpload[]", document.getElementById('fileToUpload').files[0]);
And it will return an array with multiple names, sizes, etc...
This worked for me:
let formData = new FormData()
formData.append('files', file1)
formData.append('files', file2)
This one worked for me
//Javascript part
//file_input is a file input id
var formData = new FormData();
var filesLength=document.getElementById('file_input').files.length;
for(var i=0;i<filesLength;i++){
formData.append("file[]", document.getElementById('file_input').files[i]);
}
$.ajax({
url: 'upload.php',
type: 'POST',
data: formData,
contentType: false,
cache: false,
processData: false,
success: function (html) {
}
});
<?php
//PHP part
$file_names = $_FILES["file"]["name"];
for ($i = 0; $i < count($file_names); $i++) {
$file_name=$file_names[$i];
$extension = end(explode(".", $file_name));
$original_file_name = pathinfo($file_name, PATHINFO_FILENAME);
$file_url = $original_file_name . "-" . date("YmdHis") . "." . $extension;
move_uploaded_file($_FILES["file"]["tmp_name"][$i], $absolute_destination . $file_url);
}
Adding [] when appending to fd works, but if you prefer to have your data grouped by file then I'd suggest doing it this way:
var files= document.getElementById('inpFile').files
var fd = new FormData()
for (let i = 0; i < files.length; i++) {
fd.append(i, files[i])
}
Now your data will be sent grouped by file instead of grouped by attribute.
This worked for me
var ins = $('.file').map(function () {
return this.files;
}).get();
for (var x = 0; x < ins; x++) {
formData.append("file", ins[x][0]);
}
This worked fine !
var fd = new FormData();
$('input[type="file"]').on('change', function (e) {
[].forEach.call(this.files, function (file) {
fd.append('filename[]', file);
});
});
$.ajax({
url: '/url/to/post/on',
method: 'post',
data: fd,
contentType: false,
processData: false,
success: function (response) {
console.log(response)
},
error: function (err) {
console.log(err);
}
});
I worked that such as:
var images = document.getElementById('fileupload').files;
var formData = new FormData();
for(i=0; i<images.length; i++) {
formData.append('files', images[i]);
}
If you are instantiating the FormData object already passing the form as a constructor parameter, the input file's name attribute must contain the square brackets.
HTML:
<form id="myForm" method="POST" action="url" enctype="multipart/form-data">
<input class="form-control form-control-lg" type="file" name="photos[]" multiple />
JS:
var formData = new FormData(document.getElementById('myForm'));
console.log(formData.getAll('photos[]'));
That worked for me!
If we have input in our html:
<input id="my-input" type="file" mutliple /> // multiple attribute to select and upload multiple files
We can get files from that input and send it to server with pure js script:
const myInput = document.getElementById('my-input') // getting our input
myInput.addEventListener('change', (event) => { // listening for file uploads
const files = event.target.files // getting our files after upload
const formData = new FormData() // create formData
for (const file of files) {
formData.append('files', file) // appending every file to formdata
}
const URL = 'http://server.com:3000'
const response = fetch(URL, {
method: 'POST',
data: formData // sending our formdata in body of post request
})
return response.json()
}
It worked perfect for me
P.S.: I used multer in backend (node.js + express), added to file upload route
upload.array("files", 10)
First argument is a property name of our files (in formdata)
Second argument is max file size
This worked for me also:
var data = new FormData();
for (const key in files)
data.append('gallery[]',files[key])
Here is the Vanilla JavaScript solution for this issue -
First, we'll use Array.prototype.forEach() method, as
document.querySelectorAll('input[type=file]') returns an array like object.
Then we'll use the Function.prototype.call() method to assign each element in the array-like object to the this value in the .forEach method.
HTML
<form id="myForm">
<input type="file" name="myFile" id="myFile_1">
<input type="file" name="myFile" id="myFile_2">
<input type="file" name="myFile" id="myFile_3">
<button type="button" onclick="saveData()">Save</button>
</form>
JavaScript
function saveData(){
var data = new FormData(document.getElementById("myForm"));
var inputs = document.querySelectorAll('input[type=file]');
Array.prototype.forEach.call(inputs[0].files, function(index){
data.append('files', index);
});
console.log(data.getAll("myFile"));
}

In your componenet.ts file
declare array selected files like this
selectedFiles = [];
// array of selected files
onFileSelected(event, type) {
this.selectedFiles.push({ type, file: event.target.files[0] });
}
//in the upload files method, append your form data like this
uploadFiles() {
const formData = new FormData();
this.selectedFiles.forEach(file => {
formData.append(file.type, file.file, file.file.name);
});
formData.append("driverid", this.driverid);
this.driverService.uploadDriverDetails(formData).subscribe(
res => {
console.log(res);
},
error => console.log(error.message)
);
}
NOTE: I hope this solution works for you friends
let fd = new FormData();
fd.append( "images" , image1 );
fd.append( "images" , image2 );
fd.append( "images" , image3 );
In this format you can send multiple file by axios.
But i had some problem with this.
only one file was uploaded when i try to append in form data and try to send this through axios.
and my problem was that i had imported {Axios} from 'axios'
but it will not gonna work.
we have to import axios from 'axios'
( look at the spelling )
then it was work perfectly for me
Create a FormData object
const formData: any = new FormData();
And append to the same keyName
photos.forEach((_photoInfo: { localUri: string, file: File }) => {
formData.append("file", _photoInfo.file);
});
and send it to server
// angular code
this.http.post(url, formData)
this will automatically create an array of object under file
if you are using nodejs
const files :File[] = req.files ? req.files.file : null;
I found this work for me!
var fd = new FormData();
$.each($('.modal-banner [type=file]'), function(index, file) {
fd.append('item[]', $('input[type=file]')[index].files[0]);
});
$.ajax({
type: 'POST',
url: 'your/path/',
data: fd,
dataType: 'json',
contentType: false,
processData: false,
cache: false,
success: function (response) {
console.log(response);
},
error: function(err){
console.log(err);
}
}).done(function() {
// do something....
});
return false;
Appending multiple files to the same key didn't work for me. I ended up appending them separately.
files.forEach((file) => {
formData.append(`file-${file.name}`, file);
})
In my application, I have one form which is rendering from partial view. From that form I want to send whole form data and selected file of file control. Form submission is using ajax call. To save selected file to folder, code I have is like below :
JavaScript function :
<script type="text/javascript">
$(function () {
$('#careerForm').submit(function (e) {
e.stopPropagation();
e.preventDefault();
var formData = new FormData();
var totalFiles = document.getElementById("fuUploadCV").files.length;
for (var i = 0; i < totalFiles; i++) {
var file = document.getElementById("fuUploadCV").files[i];
formData.append("FileUpload", file);
}
$.ajax({
type: "POST",
url: '/CareerSurface/UploadImage/', //put your controller/action here
data: formData,
dataType: 'json',
contentType: false,
processData: false,
beforeSend: function (xhr) {
//do something before send
},
success: function (data) {
//do something if success
},
error: function (data) {
//do something if error
}
});
});
});
</script>
Html :
using (Html.BeginForm("ApplyNow", "CareerSurface", FormMethod.Post, new { enctype = "multipart/form-data", autocomplete = "off", id ="careerForm" })){
<div class="Field-Label-Box">
<label>First Name:<span> *</span></label>
</div>
<div class="Field-Value-Box">
#Html.TextBoxFor(model => model.FirstName, new { id = "txtFirstName", name = "txtFirstName", required = "required" })
#Html.ValidationMessageFor(model => model.FirstName)
</div>
......
<div class="Field-Label-Box">
<label>Upload CV:<span> *</span></label>
</div>
<div class="Field-Value-Box">
#Html.TextBoxFor(model => model.ResumeUpload, new { type = "file", id = "fuUploadCV", name = "fuUploadCV", required = "required" })</div>
<input type="submit" id="btnSave" value="Submit" name="btnSave" />
}
c# :
[HttpPost]
public void UploadImage()
{
if (Request.Files.Count > 0)
{
dynamic file = Request.Files[0];
//do something with your 'file'
}
}
This works perfect to send only selected file. Now my issue is I want to send all another data(model class object) also to the same controller method. I have tried using json also but getting error of 'Illegal Invocation'.
Please guide me how to pass both to gather to single method? If any query, fill free to ask. Help me I got stuck at this point.
Thanks.
I made a test on your code and the only thing you are missing is adding the other fields to the FormData object you are sending through AJAX. What I mean is to modify your javascript code like this:
var formData = new FormData();
var totalFiles = document.getElementById("fuUploadCV").files.length;
for (var i = 0; i < totalFiles; i++) {
var file = document.getElementById("fuUploadCV").files[i];
formData.append("FileUpload", file);
}
// This is what you are missing: adding the other form fields
var txtFirstName = $("#txtFirstName").val();
formData.append("txtFirstName", txtFirstName);
$.ajax({
(... the rest of your code ...)
You need to append every value of your form you want to send to the server.
Then in the server side, you can access your fields in the following way, also based on your current code:
[HttpPost]
public void UploadImage()
{
if (Request.Files.Count > 0)
{
dynamic file = Request.Files[0];
//do something with your 'file'
// This is the way to access your fields based on your code
string txtFirstName = Request.Form["txtFirstName"];
// do something with your fields
}
}
I hope that helps.
How can I send an image from an input element with Javascript?
This is my image element:
<input type="file" name="imagefile" onChange="fileThumbnailHeader(this.files);" accept="image/*" id="header-img-upload" class="header-img-upload" />
And here is my function where I post other text fields with:
function registerDetails(){
var register_location = document.getElementById('register_location').value;
var register_country = document.getElementById('register_country').value;
var register_language = document.getElementById('register_language').value;
var register_interests = document.getElementById('register_interests').value;
var register_homepage = document.getElementById('register_homepage').value;
var register_music = document.getElementById('register_music').value;
var register_films = document.getElementById('register_films').value;
var register_books = document.getElementById('register_books').value;
var register_relationship = document.getElementById('register_relationship').value;
var register_age = document.getElementById('register_age').value;
var register_school = document.getElementById('register_school').value;
var register_phone = document.getElementById('register_phone').value;
var register_job = document.getElementById('register_job').value;
$.post( versionMode + "register_step_one_update.php",{city : register_location, country : register_country, language : register_language, tags : register_interests, website : register_homepage, music : register_music, movies : register_films, books : register_books, relation : register_relationship, age : register_age, school : register_school, phone : register_phone, job : register_job}, function( data ) {
alert(data);
});
}
How can I send the image with it?

I have a form with files. I would like to perform a server-side validation and only then upload the files (since each file makes the request larger).
Is there slick way to do that doesn't include serializing the form's data and running an ajax?
I'm not looking for something like this:
var formData = $('#form').serializeArray();
$.post(url, formData, function(res){
if(res.isValid)
$('#form').submit();
});
Try something like this (for Client side validation) , onclick of submit button
var file = $('#file_upload').prop("files")[0]; //file_upload is form's id
var name = file.name;
var size = file.size;
var type = file.type;
if (type != 'image/png' && type != 'image/jpeg' )throw {"msg": 'Invalid image type'}
if (size > 1024 * 1024 * 2 )throw {"msg": 'Invalid image size'}
And for AJAX Server Side Validation before upload, you need to send file object via Ajax( ***not recommended, might not work in few old browsers)
try {
var formObj = new FormData($('form')[1]); //File Object
$.ajax({
url: "YOUR URL", // do the SERVER SIDE VALIDATION here
data: formObj,
processData: false,
contentType: false,
dataType:'json',
type: 'POST',
success: function(data){
// Success code
}
});
}catch (e) {
console.log(e.msg);
}
out.html is entry point. submitValidate submits form in iframe (in.html). JavaScript snippet (confirm.html) in response from server passes database record to validateClientSideAndUpload which sets hidden field and submits form in parent window to server. Server moves file to appropriate location and creates association with record speficied by id. Posted as a proof of concept.

<script>
function submitValidate() {
document.getElementById('validate-frame')
.contentDocument.querySelector('form').submit();
}
function validateClientSideAndUpload(id) {

alert('Select file');
return;
}
document.getElementById('record-id').value = id;
var form = document.querySelector('form');

form.submit();
}

In your componenet.ts file
declare array selected files like this
selectedFiles = [];
// array of selected files
onFileSelected(event, type) {
this.selectedFiles.push({ type, file: event.target.files[0] });
}
//in the upload files method, append your form data like this
uploadFiles() {
const formData = new FormData();
this.selectedFiles.forEach(file => {
formData.append(file.type, file.file, file.file.name);
});
formData.append("driverid", this.driverid);
this.driverService.uploadDriverDetails(formData).subscribe(
res => {
console.log(res);
},
error => console.log(error.message)
);
}
NOTE: I hope this solution works for you friends
let fd = new FormData();
fd.append( "images" , image1 );
fd.append( "images" , image2 );
fd.append( "images" , image3 );
In this format you can send multiple file by axios.
But i had some problem with this.
only one file was uploaded when i try to append in form data and try to send this through axios.
and my problem was that i had imported {Axios} from 'axios'
but it will not gonna work.
we have to import axios from 'axios'
( look at the spelling )
then it was work perfectly for me
Create a FormData object
const formData: any = new FormData();
And append to the same keyName
photos.forEach((_photoInfo: { localUri: string, file: File }) => {
formData.append("file", _photoInfo.file);
});
and send it to server
// angular code
this.http.post(url, formData)
this will automatically create an array of object under file
if you are using nodejs
const files :File[] = req.files ? req.files.file : null;
I found this work for me!
var fd = new FormData();
$.each($('.modal-banner [type=file]'), function(index, file) {
fd.append('item[]', $('input[type=file]')[index].files[0]);
});
$.ajax({
type: 'POST',
url: 'your/path/',
data: fd,
dataType: 'json',
contentType: false,
processData: false,
cache: false,
success: function (response) {
console.log(response);
},
error: function(err){
console.log(err);
}
}).done(function() {
// do something....
});
return false;
Appending multiple files to the same key didn't work for me. I ended up appending them separately.
files.forEach((file) => {
formData.append(`file-${file.name}`, file);
})
