JQuery fomdata sending empty data to php file? - php

I am trying to upload file through jquery formdata without any form. My problem is that it is not sending any data to php file.
Here is my jquery code
jQuery(document).ready(function() {
jQuery('#e_picture').change(function() {
var file_data = jQuery('#e_picture').prop('files')[0];
var form_data = new FormData();
form_data.append('e_picture', file_data);
form_data.append('e_uid', '3585');
//});
// data: {e_uid: e_uid, e_picture:'23'},
jQuery.ajax({
url: "index.php?option=com_objectified&task=course_reg.addPicture",
type: 'POST',
data: {
form_data
},
processData: false,
contentType: false,
success: function(result) {
alert('This is ' + result); // Here I show onlu e_uid but it alerts blank result
}
});
});
});
Html
<input type="file" class="form-control" name='e_picture' id='e_picture'>

You are sending the form_data in wrong way
instead of
data: {
form_data
},
just send it like
data: form_data,

jQuery(document).ready(function() {
jQuery('#e_picture').change(function() {
var file_data = jQuery('#e_picture')[0].files;
var form_data = new FormData();
form_data.append("e_picture[]", file_data[0]);
form_data.append('e_uid', '3585');
//});
// data: {e_uid: e_uid, e_picture:'23'},
jQuery.ajax({
url: "index.php?option=com_objectified&task=course_reg.addPicture",
type: 'POST',
data: {
form_data
},
processData: false,
contentType: false,
success: function(result) {
alert('This is ' + result); // Here I show onlu e_uid but it alerts blank result
}
});
});
});

ange content type to :
contentType: 'multipart/form-data',

Submit data with attachment Ajax and PHP

I have to submit data with attachment using java scripts and PHP, my problem is that I cant pass data and attachment to php page. here is my codes;
In my HTML i did not use
function kk_sendmail()
{
var kk_vtype= $("#vtype").val();
var kk_departm= $("#departm").val();
var kk_recepient= $("#recepient").val();
var kk_user= $("#euser").val();
var kk_smssubject= $("#smssubject").val();
var kk_compose_textarea= $("#compose-textarea").val();
var form_data = new FormData();
form_data.append('attach', $('#attachments').prop('files')[0]);
form_data.append('vtype',kk_vtype);
form_data.append('departm',kk_departm);
form_data.append('recepient',kk_recepient);
form_data.append('euser',kk_user);
form_data.append('smssubject',kk_smssubject);
form_data.append('compose-textarea',kk_compose_textarea);
$.ajax({
type: "POST",
url: "process.php",
dataType: 'text',
cache: false,
contentType: false,
processData: false,
data: form_data,
success : function(text){
if (text == "success"){
formSuccess();
} else {
console.log('Failed message');
}
}
});
};
you do not need to define the dataType and also you can use
enctype: "multipart/form-data",
$('#attachements')[0].files[0] // for file
It will help

Uploading an image without form submitting

<input type='file' name='inputfile' id='inputfile'>
I'm trying to upload an image without a form submitting - just after input file is changed:
$('#inputfile').change(function(){
$.ajax({
url: "pro-img-disk.php",
type: "POST",
data: new FormData('#inpufile'),
contentType: false,
cache: false,
processData:false,
success: function(data){
console.log(data);
}
});
});
PHP
$src = $_FILES['inputfile']['tmp_name'];
$targ = "../images/".$_FILES['inputfile']['name'];
move_uploaded_file($src, $targ);
Error:
Undefined index: inputfile...
Any help?
See to the following changes:
<input type='file' name='inputfile' id='inputfile'>
Here's how you should have sent the ajax request:
$(document).ready(function() {
$('#inputfile').change(function(){
var file_data = $('#inputfile').prop('files')[0];
var form_data = new FormData();
form_data.append('file', file_data);
$.ajax({
url: "pro-img-disk.php",
type: "POST",
data: form_data,
contentType: false,
cache: false,
processData:false,
success: function(data){
console.log(data);
}
});
});
});
And lastly, here's how you should have processed the form data:
$src = $_FILES['file']['tmp_name'];
$targ = "../images/".$_FILES['file']['name'];
move_uploaded_file($src, $targ);
Try this:
var file_data = $('#inputfile').prop('files')[0];
var form_data = new FormData(); // Create a form
form_data.append('inputfile', file_data); // append file to form
$.ajax({
url: "pro-img-disk.php",
type : 'post',
cache : false,
contentType : false,
processData : false,
data : form_data,
success : function(response){
alert(response);
}
});
in php you can get the file data like:
$_FILES['inputfile']

AJAX send data to PHP file

send $username php with data: new FormData(this), to add.php like data: new FormData(this),$username how can i do it with ajax code
<script type="text/javascript">
$(document).ready(function (e) {
$("#uploadFormuserimg").on('submit',(function(e) {
e.preventDefault();
$.ajax({
url: "add.php",
type: "POST",
data: new FormData(this),
contentType: false,
cache: false,
processData:false,
success: function(data)
{
$("#user_img_a").html(data);
},
error: function()
{ alert("error");
}
});
}));
});
</script>
var myData = new FormData(this);
myData.append('username','<?php echo $username; ?>');
and get on "add.php" like this
$username = $_POST['username'];
This worked on my side.
Based on comments to the question, specifically:
I just want to add some data
Are you just asking how to add more fields to the object that was created already in the data value? Something like this:
var myData = new FormData(this);
myData.append("anotherField", "anotherValue");
// etc.
Then just use that variable as your AJAX data:
$.ajax({
url: "add.php",
type: "POST",
data: myData,
contentType: false,
cache: false,
processData:false,
success: function(data)
{
$("#user_img_a").html(data);
},
error: function()
{ alert("error");
}
});
You can store anything you like in a variable and use that variable at a later time. With a FormData object you would generally use .append() to add more key/value pairs to it.

access the data passed through FormData on clicking submit button

I have a form with several input fields including file inputs.I am using jquery validate plugin.I need to submit the form using ajax.
HTML:
<form method="post" name="addstudent" id="registrationform" enctype="multipart/form-data">
some fields
<input type="submit" id="buttontext"
class="student_registrationform_button" value="submit" />
Jquery:
$('#buttontext').click(function(){
$("#registrationform").validate({
invalidHandler: function(event, validator) {
//some code
},
submitHandler: function(form){
formdata = false;
if (window.FormData) {
formdata = new FormData();
}
var i = 0, len = $(".file").length, img, reader, file;
$('.file').each(function() { var file = this.files[0];
if (window.FileReader) {
reader = new FileReader();
reader.readAsDataURL(file);
}
if (formdata) {
formdata.append("file", file);
}
});
$.ajax({
url: "process.php",
type: 'POST',
//data: $(this).serialize(),
data: formdata,
cache: false,
contentType: false,
processData: false,
success:function(data){ //alert(data);
console.log(data);return false;
}
Process.php
When I check echo 'action:'.var_dump($_POST); ,its showing null string
(function($) {
$.fn.serializefiles = function() {
var obj = $(this);
var form_data = new FormData(this[0]);
$.each($(obj).find('input[type="file[]"]'), function(i, tag) {
$.each($(tag)[0].files, function(i, file) {
form_data.append(tag.name, file);
});
});
var params = $(obj).serializeArray();
$.each(params, function (i, val) {
form_data.append(val.name, val.value);
});
return form_data;
};
})(jQuery);
var form_id = $('#registrationform');
$.ajax({
type: "POST",
url: "process.php",
data: form_id.serializefiles(),
cache: false,
processData: false,
contentType: false,
success: function (response) {
console.log(data);return false;
}
});
Try this simple function:
submitHandler: function(form){
formdata = new FormData(form);
$.ajax({
url: "process.php",
type: 'POST',
//data: $(this).serialize(),
data: formdata,
cache: false,
contentType: false,
processData: false,
success:function(data){ //alert(data);
console.log(data);return false;
}

A FormData object is always empty when trying to upload a file using AJAX

When trying to upload an image using AJAX without submitting the form directly and sending a FormData object to server it returns empty $_FILES array. But if I submit the form using <input type="submit"> tag $_FILES array is not empty and recieves the data.
HTML
<form action="core/update.php" method="post" enctype="multipart/form-data" id="profile-photo" name="profile-photo-form">
<input type="file" id="photo-filename" name="avatar" class="edit-show panel photo-upload">
</form>
<button class="save-button" disabled="disabled">Save</button>
JS
$('#profile-photo').on('submit', function(e) {
e.preventDefault();
var form = $('#profile-photo')[0];
var formData = new FormData(form);
formData.append('avatar', $('#photo-filename')[0].files[0]);
$.ajax({
url: "core/update.php",
data: formData,
type: "POST",
contentType: false,
cache: false,
processData: false
});
console.log(formData);
});
$('.save-button').on('click', function() {
if ($('#photo-filename').val != '') {
$('#profile-photo').submit();
};
}
UPD
Also $('#profile-photo').serialize() returns blank string.
UPD 2
Can it conflict with the other AJAX-requests on the page?
Try this:
Because user may upload multiple files
jQuery.each(jQuery('#photo-filename')[0].files, function(i, file) {
data.append('file-'+i, file);
});
Instead of
formData.append('avatar', $('#photo-filename')[0].files[0]);
Complete Solution:
$('#profile-photo').on('submit', function(e) {
e.preventDefault();
var form = $('#profile-photo')[0];
var formData = new FormData(form);
jQuery.each(jQuery('#photo-filename')[0].files, function(i, file) {
formData.append('file-'+i, file);
});
$.ajax({
url: "core/update.php",
data: formData,
type: "POST",
contentType: false,
cache: false,
processData: false
});
console.log(formData);
});
Try the following,
$('#profile-photo').on('submit', function(e) {
e.preventDefault();
var formData = new FormData(this); // here I am editing
formData.append('avatar', $('#photo-filename')[0].files[0]);
$.ajax({
url: "core/update.php",
data: formData,
type: "POST",
contentType: false,
cache: false,
processData: false
});
console.log(formData);
});
If it is only the file you want to send then you can do it as below and no need to attach form here to formdata:
$('#profile-photo').on('submit', function(e) {
e.preventDefault();
var formdata = new FormData();
var fileInput = $('#photo-filename');
//Use Either this
$.each($(fileInput).get(0).files, function (index, value) {
formdata.append('avatar', value);
});
//Or this
$.each($(fileInput).get(0).files, function (index, value) {
formdata.append(value.name, value);
});
//For single file use this
formData.append('avatar', $('#photo-filename')[0].files[0]);
$.ajax({
url: "core/update.php",
data: formData,
type: "POST",
contentType: false,
cache: false,
processData: false
});
console.log(formData);
});
