I have a long multistep form. which have text inputs and an upload file option. I'm trying to submit it to PHP with Ajax. I have tried FormData but I'm not sure how to send other select and text input fields.

How can I do this?
const addListingForm = $('#add-listing-form');
addListingForm.on('submit', function (e) {
console.log('Submitted');
const formData = new FormData(document.getElementById('add-listing-form'));
$.ajax({
url: `${SITE_URL}/private/shared/process`,
type: 'post',
data: formData,
processData: false,
contentType: false,
success: function (resp) {
console.log(resp);
},
error: function (err) {
console.log(err);
},
});
e.preventDefault();
});
<form action="" method="post" enctype="multipart/form-data" id="add-listing-form">
<input type="text" name="title" id="title" class="custom-input" />

Submit
</button>
</form>
try this
let title = document.getElementById("title").value;
let firstFile= document.getElementById("list-photos[]").files[0];
let formData = new FormData();
formData.append("file1", firstFile);
formData.append("title", title );
//and add more
or
let title = document.getElementById("title").value;
let firstFile= document.getElementById("list-photos[]").files[0]; // file from input
let req = new XMLHttpRequest();

$imagename=$_FILES['image']['name'];
echo($imagename);
?>
This always return undefined index image error ,please help.
Change
<form enctype: 'multipart/form-data'>
to
<form id="myform" enctype= 'multipart/form-data'>
Change your function to:
function addcategory(){
var formData = new FormData( $("#myform")[0] );
$.ajax({
url : 'performcategoryserver.php',
type : 'POST',
data : formData,
async : false,
processData: false, // tell jQuery not to process the data
contentType: false, // tell jQuery not to set contentType
dataType:"json",
success : function(data) {
alert(data);
}
});
}
Your form tag opened in wrong way firstly can you fix that and try again ?
<form enctype: 'multipart/form-data'>
Should be
<form method="post" enctype="multipart/form-data">
Finally found the working code,
Changed this:
<form id="myform" enctype= 'multipart/form-data'>
Changed this:
function addcategory(){
var formData = new FormData( $("#myform")[0] );
var xhr = new XMLHttpRequest();
// Open connection
xhr.open('POST', 'performcategoryserver.php', true);
// Set up handler for when request finishes
xhr.onload = function () {
if (xhr.status === 200) {
//File(s) uploaded
alert(xhr.responseText);
} else {
alert('An error occurred!');
}
};
// Send data
xhr.send(formData);
}
I have two forms one with product details like price, description and name. And the other with images, they both have different Ajax but they send data to the same route. I want to submit them with one button. So if I click a submit button it should submit all data at once which are price, name, image etc. How can I do this if possible?

How to upload a file using jQuery.ajax and FormData
(2 answers)
Closed 3 years ago.
I am trying to upload a form with jQuery and Ajax using Laravel as server side code, my form is:
HTML:
<form action="" method="post">
<div class="form-group">
<label for="exampleInputEmail1">Comprobante</label>
<input type="file" name="file" class="form-control" id="file" aria-describedby="emailHelp">
</div>
<div class="form-group">
<label for="exampleInputEmail1">Nombre</label>
<input type="text" name="name" class="form-control" id="name" aria-describedby="emailHelp" placeholder="Enter name">
</div>
</form>
jQuery, Ajax:
$( 'body' ).on( "submit", 'form', function() {
event.preventDefault();
var formData = new FormData();
formData.append("file", $('#file')[0].files[0]);
formData.append("name", $('#name').val());
var formData = $(this).serialize();
$.ajax({
type:'POST',
url:"{{ url('/accountability/store') }}",
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
data: formData,
success:function(html)
{
alert('stored!');
}
});
});
Laravel:
$extension = $request->file('file')->getClientOriginalExtension();
$filename = $request->rut.'_rendicion_'. date('d_m_Y_h_i_s') .'.'.$extension;
Storage::disk('dropbox')->putFileAs(
'/intranet_jisparking_archivos_web/',
$request->file('file'),
$filename
);
The problem is that it says that
Call to a member function getClientOriginalExtension() on null
But I do not understand why? because I am uploading the file with this $('#file')[0].files[0] in the jQuery. It looks like $request->file('file') is empty, how can I fix it?
Thanks!
Try this:
var formData = new FormData();
var file = $('#file').prop('files')[0];
formData.append('file', file);
formData.append('other_variable', $('#other_variable').val());
// Don't use serialize here, as it is used when we want to send the data of entire form in a query string way and that will not work for file upload
$.ajax({
url: '{{ url("your_url") }}',
method: 'post',
data: formData,
contentType : false,
processData : false,
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
success: function(response){
// Do what ever you want to do on sucsess
}
});
In controller method, you will get the file like:
$file = Input::file('file');
I'm trying to, on a webpage, select a file and post it in Slack via the Slack API.
I was originally doing:
var request = require('request');
$(".submit").click(function(){
request.post({
url: 'https://slack.com/api/files.upload',
formData: {
token: "myTokenHere",
title: "Image",
filename: "image.png",
filetype: "auto",
channels: "mychannel",
file: document.getElementById('idofuploadelement').files[0]
},
}, function (err, response) {
console.log(JSON.parse(response.body));
});
So then I switched to trying Ajax so that I don't have to include require.
$(".submit").click(function(){
$.ajax({
type: "POST",
method: "POST",
enctype: "multipart/form-data",
url: 'https://slack.com/api/files.upload',
formData: {
token: "myTokenHere",
title: "Image",
filename: "image.png",
filetype: "auto",
channels: "mychannel",
file: document.getElementById('idofuploadelement').files[0]
}
}).done(function(url) {
console.log(url);
});
});
but this gives me the console warning
Form contains a file input, but is missing method=POST and enctype=multipart/form-data on the form. The file will not be sent.
Even though I have those properties (I got the error before adding them too), I still get the error.
My html is simple html5 input tags (for upload and submit button)
<input type="file" name="fileToUpload" id="idofuploadelement">
<input type="submit" name="submit" class="submit action-button next" value="Next"/>
In a nutshell, I'm trying to get a file sent to me (in any way, Slack, Github, email, whatever) without having to spin up a server. Is it possible?
Figured it out:
HTML:
<form id="myform" method="POST" enctype="multipart/form-data">
<input type="file" name="fileToUpload" id="file-select">
<input id="upload-button" type="submit" name="submit" class="submit action-button next" value="Next"/>
</form>
JS:
var form = document.getElementById('myform');
var fileSelect = document.getElementById('file-select');
var uploadButton = document.getElementById('upload-button');
form.onsubmit = function(event) {
event.preventDefault();
// Update button text.
uploadButton.innerHTML = 'Uploading...';
var file = fileSelect.files[0];
var formData = new FormData();
formData.append('file', file, file.name);
formData.append('token', insert_token_here);
formData.append('channels', insert_channel_here);
var xhr = new XMLHttpRequest();
xhr.open('POST','https://slack.com/api/files.upload', true);
// Set up a handler for when the request finishes.
xhr.onload = function () {
if (xhr.status === 200) {
// File(s) uploaded.
uploadButton.innerHTML = 'Uploaded';
} else {
alert('An error occurred!');
}
};
xhr.send(formData);
}
I am trying to test a simple FormData object but its not working at all. jsfiddle: https://jsfiddle.net/8j80898h/
html code:
<form id="createForm" name="createForm" novalidate enctype="multipart/form-data">
<input type="hidden" name="name" value="Name1" />
<input type="file" name="file" />
<input type="button" id="submitIt" value="Submit" />
</form>
js:
$(document).ready(function() {
$('#submitIt').click(function() {
var fd = new FormData($('#createForm')[0]);
fd.append( 'name', $('input[name=name]').val());
$.ajax({
url: url,
data: fd,
processData: false,
contentType: false,
type: 'POST',
success: function(data){
alert(data);
}
});
});
});
Server is always getting null values for name and file
FormData has a get method you should use:
$(document).ready(function() {
$('#submitIt').click(function() {
var d = new FormData($('form')[0]);
alert(d.get('name'));
});
});
read more in MDN: https://developer.mozilla.org/en-US/docs/Web/API/FormData/get
rather than making an FormData object you can access elements within an form like the code below shows :)
$(document).ready(function() {
$('#submitIt').click(function() {
var d = $('form').toArray();
alert(d[0].name);
});
});
