Dropzone display server images but not saving laravel

I'm using Dropzone.js,I displayed server images inside dropzone box with remove link and it works fine but my problem is when I click on butto to save uploaded images server images not saving in database just new uploaded images are saving
my code
<script type="text/javascript">
Dropzone.options.dropzone =
{
autoProcessQueue: false,
maxFiles: 50,
maxFilesize: 12,
acceptedFiles: ".jpeg,.jpg,.png,.gif",
addRemoveLinks: true,
uploadMultiple: true,
timeout: 50000,
init: function () {
var myDropzone = this;
$.get('/getphoto',{'key': $('[name=key]').val()},function(data){
var files = data;
console.log(files.length);
for (var i = 0; i < files.length; i++) {
var name= files[i].name;
var link = "http://127.0.0.1:8000/storage/images/events/galleries/"+ name;
console.log(link);
var mockFile = { name: files[i].name, size: 128456, type: 'image/png', url:link};
myDropzone.emit('addedfile', mockFile);
myDropzone.options.thumbnail.call(myDropzone, mockFile, link);
myDropzone.emit('complete', mockFile);
myDropzone.files.push(mockFile);
var existingFileCount = 1; // The number of files already uploaded
myDropzone.options.maxFiles = myDropzone.options.maxFiles - existingFileCount;
}
});
// Update selector to match your button
$("#button").click(function (e) {
e.preventDefault();
myDropzone.processQueue();
});
this.on('sending', function(file, xhr, formData) {
// Append all form inputs to the formData Dropzone will POST
var data = $('#dropzone').serializeArray();
$.each(data, function(key, el) {
formData.append(el.name, el.value);
});
});
},
removedfile: function(file)
{
var fileRef;
return (fileRef = file.previewElement) != null ?
fileRef.parentNode.removeChild(file.previewElement) : myDropzone.removeFile(file);
},
success: function(file, response)
{
var name = file.upload.filename;
console.log(name);
window.location.href = "{{ route('eventlist') }}";
},
error: function(file, response)
{
return false;
}
};
function del(file)
{
console.log(file.name);
return myDropzone.removeFile(file);
}
</script>
my view blade:
<div>
<form action="{{ route('savegallery',$event->id) }}" class="dropzone" id="dropzone" method="POST" class="dropzone" enctype="multipart/form-data">

</div>
First I delete all images then I get images from dropzone then save it
public function savegallery(Request $request,$id){
$eventgalleries = Eventgallery::where('event_id',$id)->delete();
foreach ($request->file('file') as $img) {
// $image = new Eventgallery;
//get file name with extention
$filenameWithExt = $img->getClientOriginalName();
//get just file name
$filename = pathinfo($filenameWithExt, PATHINFO_FILENAME);
//GET EXTENTION
$extention = $img->getClientOriginalExtension();
//file name to store
$fileNameToStore = $filename . '_' . time() . '.' . $extention;
//upload image
$path = $img->storeAs('public/images/events/galleries', $fileNameToStore);
$url = asset('storage/images/events/galleries/' . $fileNameToStore);
$img = new Eventgallery;
$img->name = $fileNameToStore;
$img->event_id = $id;
$img->save();
}
return redirect()->route('eventlist')->with('success', 'The galleries created successfully.');
}
and this function for route (/getphoto) to get all images and then display it in dropzone
public function getphoto(){
$data = Eventgallery::all()->toArray();
return $data;
}
Can someone help me I spend many days to find a solve but no result.

How to get the image path on dynamically adding new file field using ajax

Here it is the main field that to dynamically add the elements. In this form by clicking add button it add the html part in the page. That works fine.
<div class="col-md-12 input_fields_wrap2"></div>
<button class="btn btn-primary add_field_button2" id="btnclr2">Add</button>
And the remaining script work is here for adding the fields.
<script>
$(document).ready(function()
{
var wrapper = $(".input_fields_wrap2"); //Fields wrapper
$('.add_field_button2').click(function(e)
{
var sub = 1;
e.preventDefault();
$(wrapper).append('<div><div class="row"><div class="col-md-4"><div class="form-group"><label>Sub-Article Heading</label><input type="text" class="form-control" id="subarticle_title" placeholder="Sub Article Heading" name="sub_article_heading[]"></div></div><div class="col-md-4"><div class="form-group"><label>Sub Article Image<span style="color: red;">*</span></label><input type="file" class="form-control required" name="file_upload1[]" id="file_upload1" value="" placeholder=""/><input type="hidden" name="giftcardpath1[]" id="giftcardpath1" value="" ><span id="giftimage1" style="display: none"><img src="" id="giftcard1"></span><span style="color: red;"></span></div></div><div class="col-md-4"><div class="form-group"><label>Sub-Article Image-Caption</label><input type="text" class="form-control" id="title" placeholder="Sub Article Image caption" name="sub_article_img_caption[]" value="" required=""></div></div><div class="col-md-12"><div class="form-group"><label>Content</label><textarea class="form-control" name="sub_article_content[]" rows="6" placeholder="Sub Articles Content..."></textarea></div></div><div class="clearfix"></div></div><a style="margin-bottom:15px; href="#" class="remove_field btn btn-danger btn-xs">Remove</a><br></div>');
$('#file_upload1').on('change',function(){
var file ;
file = this.files[0];
var img = new Image();
var _URL = window.URL || window.webkitURL;
img.src = _URL.createObjectURL(file);
img.onload = function () {
var reader = new FileReader();
reader.onloadend = function() {
// alert(reader.result);
$.ajax({
type: "POST",
url: base_url+"Admin/UploadImg",
data: {
imgBase64: reader.result,
}
}).done(function(data){
data = $.parseJSON(data);
if(data.imgpath!='')
{
$('#giftcardpath1').val(data.imgpath);
alert('Image upload successfull');
}
});
}
reader.readAsDataURL(file);
};
});
sub +=1;
});
//user click on remove text
$(wrapper).on("click",".remove_field", function(e)
{
e.preventDefault();
$(this).parent('div').remove();
});
});
</script>
But the Main problem is whenever i am upload a first file it works fine and display the alert and image path but later uploading image in second added field it can not store the path of that second image and did not display the alert.
My Upload image code is
public function UploadImg()
{
$rawData = $_POST['imgBase64'];
$filteredData = explode(',', $rawData);
$unencoded = base64_decode($filteredData[1]);
$datime = time();
$fp = fopen('upload_dataimage/'.$datime.'.jpg', 'w');
fwrite($fp, $unencoded);
fclose($fp);
$img_url = 'upload_dataimage/'.$datime.'.jpg';
echo json_encode(array('result'=>'1','imgpath'=>$img_url));
exit;
}
please help me to get rid of this problem and made me happy.
Thanks in advance..

how to upload an image with a text post AJAX, php, and html

Hi i am trying to upload an image with comments added to it into a database using php ajax and html.
here is the html part:
<form name="form1" enctype="multipart/form-data" action="">
<h2></h2>
<div class="form-group">
<textarea name="msg" class="form-control status-box" id="post" rows="3" cols="60" placeholder="What\'s on your mind?"></textarea>
<p>Upload an image.</p>
<input type="file" id="postPhoto" name="postPhoto" value="upload" placeholder="Upload Image">
</div>
</form>
<div class="button-group pull-right">
<p class="counter">200</p>
<a href="#" type="submit" onclick="submitChat()" class="post btn btn-primary">
Post</a>
</div><br><br>
this is what i have to the ajax which is on the same page as the html
<script>
function submitChat() {
var file = document.getElementById("postPhoto");
var formData = new FormData();
// alert(formData);
formData.append("file[]", file.files[0]);
if(form1.msg.value == '') {
alert('You must Enter a Post');
return;
}
var msg = form1.msg.value;
var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
if(xmlhttp.readyState==4 && xmlhttp.status==200) {
document.getElementById('logs').innerHTML = xmlhttp.responseText;
console.log(xmlhttp.statusText);
}
}
xmlhttp.open('POST', 'userposts.php?msg='+msg, true);
xmlhttp.setRequestHeader("Content-type", "multipart/form-data");
xmlhttp.send(formData);
}
<script>
and this is the php part:
$msg = stripslashes(htmlspecialchars($_REQUEST['msg']));
if(isset($_FILES['postPhoto']['type'])) {
$imageData = "";
$validextensions = array("jpeg", "jpg", "png");
$temporary = explode(".", $_FILES['postPhoto']['name']);
$file_extension = end($temporary);
if((($_FILES['postPhoto']['type'] === 'image/png') || ($_FILES['postPhoto']['type'] == 'image/jpg') || ($_FILES['postPhoto']['type'] == 'image/jpeg')) && ($_FILES['postPhoto']['size'] < 2500000) && in_array($file_extension, $validextensions)) {
if($FILES['postPhoto']['error'] > 0) {
echo "return code: " . $_FILES['postPhoto']['error'] . "<br/><br/>";
}
else {
$imageData = mysqli_real_escape_string($connection, file_get_contents($_FILES["postPhoto"]["tmp_name"]));
}
}
}
$stmt = "INSERT INTO posts VALUES ('', '$uname', '$msg', '$imageData')";
$result = $connection->query($stmt);
the images do not seem to be getting sent to the php file idk how to go about fixing this. any help would be much appreciated.

Maybe Helpful,
You simply can't upload a file with pure Javascript ajax functions (at least not in a cross browser way, see this article for more information)
This is because XMLHttpRequest has no support for multipart/form-data, you can do tricks like using an iframe or use flash.
There are enough articles on the internet that explain this.(maybe helpful)
http://www.ajaxf1.com/tutorial/ajax-file-upload-tutorial.html
http://www.faqs.org/rfcs/rfc2388.html
Recomand
Use jQuery Ajax. which have easy lib. support and functions to upload images and submit/parse to destination files.
below sample jQuery AJAX code for demo
$(document).ready(function(){
$(document).on('submit','form[name="form1"]',function(e){
e.preventDefault();
var form = $(this)[0];
var formData = new FormData(form);
$.ajax({
url: 'Your url here',
data: formData,
type: 'POST',
// THIS MUST BE DONE FOR FILE UPLOADING
contentType: false,
processData: false,
// ... Other options like success and etc
success : function(data){
//Do stuff for ahed process....
}
});
});
});

PHP - Uploading multiple files with Javascript and PHP

its me again. Im currently trying to build an multiple file uploader for my site but dont know how to get/handle all files. I think showing you the code first will be a better explanation:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>NDSLR - Demo Upload</title>
</head>
<body>
<script type="text/javascript">
function fileChange()
{
//FileList Objekt aus dem Input Element mit der ID "fileA"
var fileList = document.getElementById("fileA").files;
//File Objekt (erstes Element der FileList)
var file = fileList[0];
//File Objekt nicht vorhanden = keine Datei ausgewählt oder vom Browser nicht unterstützt
if(!file) {
return;
}
var x = substr(file.name, -4);
document.getElementById("status").innerHTML = x;
/*
if (x != ".pdf") {
document.getElementById("fileA").files = null;
file = null;
fileList = null;
alert("Wrong Data");
return;
} */
document.getElementById("fileName").innerHTML = 'Dateiname: ' + file.name;
document.getElementById("fileSize").innerHTML = 'Dateigröße: ' + file.size + ' B';
document.getElementById("progress").value = 0;
document.getElementById("prozent").innerHTML = "0%";
}
var client = null;
function uploadFile()
{
//Wieder unser File Objekt
for(i=0;i < document.getElementById("fileA").files; i++) {
var file = document.getElementById("fileA").files[i];
//FormData Objekt erzeugen
var formData = new FormData();
//XMLHttpRequest Objekt erzeugen
client = new XMLHttpRequest();
var prog = document.getElementById("progress");
if(!file)
return;
prog.value = 0;
prog.max = 100;
//Fügt dem formData Objekt unser File Objekt hinzu
formData.append("datei", file);
client.onerror = function(e) {
alert("onError");
};
client.onload = function(e) {
document.getElementById("prozent").innerHTML = "100%";
prog.value = prog.max;
};
client.upload.onprogress = function(e) {
var p = Math.round(100 / e.total * e.loaded);
document.getElementById("progress").value = p;
document.getElementById("prozent").innerHTML = p + "%";
};
client.onabort = function(e) {
alert("Upload abgebrochen");
};
client.open("POST", "upload.php");
client.send(formData);
}
}
}
function uploadAbort() {
if(client instanceof XMLHttpRequest)
//Briecht die aktuelle Übertragung ab
client.abort();
}
</script>
<form action="" method="post" enctype="multipart/form-data">
<input name="file[]" type="file" multiple="multiple" id="fileA" onchange="fileChange();"/>
<input name="upload[]" value="Upload" type="button" accept=".dem" onclick="uploadFile();" />
<input name="abort" value="Abbrechen" type="button" onclick="uploadAbort();" />
</form>
<div id="status"></div>
<div id="fileName"></div>
<div id="fileSize"></div>
<div id="fileType"></div>
<progress id="progress" style="margin-top:10px"></progress> <span id="prozent"></span>
</div>
</body>
</html>
So this is my HTML Code and following up my upload.php:
<?php
if (isset($_FILES['datei']))
{
move_uploaded_file($_FILES['datei']['tmp_name'], 'upload/'.$_FILES['datei']['name']);
}
?>
My Problem currently is, that i dont know how to implement the multiple upload or better said, how to upload all files at all.

There are some tutorials in the internet, that you can simply find by googling "multiple file upload". Anyway here is one of the examples:
The HTML
<!-- IMPORTANT: FORM's enctype must be "multipart/form-data" -->
<form method="post" action="upload-page.php" enctype="multipart/form-data">
<input name="filesToUpload[]" id="filesToUpload" type="file" multiple="" />
</form>
Listing Multiple Files with JavaScript
//get the input and UL list
var input = document.getElementById('filesToUpload');
var list = document.getElementById('fileList');
//empty list for now...
while (list.hasChildNodes()) {
list.removeChild(ul.firstChild);
}
//for every file...
for (var x = 0; x < input.files.length; x++) {
//add to list
var li = document.createElement('li');
li.innerHTML = 'File ' + (x + 1) + ': ' + input.files[x].name;
list.append(li);
}
The input.files property provides an array of files for which you can check the length; if there's a length, you can loop through each file and access the file paths and names.
Receiving and Handling Files with PHP
if(count($_FILES['uploads']['filesToUpload'])) {
foreach ($_FILES['uploads']['filesToUpload'] as $file) {
//do your upload stuff here
echo $file;
}
}
PHP creates an array of the files uploaded with the given INPUT's name. This variable will always be an array within PHP.

This is uploading using ajax. There are other ways such the use of iframe and jquery's $.load().
ajax_upload.js
Hmm... FormData is not IE-safe. So, you may want to resort to iframe & $.load().
function doUpload(fle_id, url_upld)
{
var upldLimit = 2000000; // 2mb by default;
if( $('#'+fle_id)[0] == undefined || $('#'+fle_id)[0].files.length == 0 ) {
alert('nothing to upload');
return;
}
// put files to formData
var tfSize = 0; // in bytes
var fd = new FormData();
$.each($('#'+fle_id)[0].files, function(i, file) {
fd.append(i, file);
tfSize = tfSize + file.size;
});
// you may check file size before sending data
if(tfSize > upldLimit) {
alert('File upload exceeded the '+(upldLimit/1000000)+' MB limit.');
return;
}
// actual data transfer
$.ajax({
url: url_upld,
cache: false,
data: fd,
type: 'POST',
contentType : false,
processData : false,
success: function(data){
alert(data);
},
error: function(jqXHR, textStatus, errorMessage) {
alert(errorMessage);
}
});
}
upload_form.html
Let's use jquery to make things simple.
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="ajax_upload.js"></script>
<script type="text/javascript">
$(function(){
$('form').submit(function(e){
if( e.preventDefault ) e.preventDefault(); // chrome/firefox
else e.cancelBubble(); // IE
// supply file input id and upload url
doUpload( 'fle', $(this).attr('action') );
});
});
</script>
Upload
<form action="ajax_upload.php"
method="post"
enctype="multipart/form-data"
accept-charset="utf-8"
>
<input type="file" id="fle" name="fle[]" multiple >
<button type="submit">Upload</button>
</form>
ajax_upload.php
<?php
if(count($_FILES) == 0) {
echo 'Nothing uploaded.';
exit;
}
$upldPath = 'E:/stack/upload/';
foreach($_FILES as $file) {
if ($file['error'] == UPLOAD_ERR_OK) {
try {
if( !move_uploaded_file( $file["tmp_name"], $upldPath . $file['name']) ) {
// abort even if one file cannot be moved.
echo 'Cannot upload one of the files.';
exit;
}
}
catch(Exception $e) {
echo 'Cannot upload the files.';
exit;
}
} else {
// abort even if one file has error.
echo 'Cannot upload one of the files.';
exit;
}
}
echo 'Upload successful!';
?>

Here is a simple approach to solving this issue.
This FormData append method works on IE 10 up and any other browser.
let files = []
let formData = new FormData
let filesInput = document.getElementById('files')
function prepareFiles() {
files = filesInput.files
}
function uploadFiles() {
// Arrange the files as form data to be sent to php
files = Array.from(files)
files.forEach(file => formData.append('files[]', file))
// See all selected files
console.log('Files')
console.log(formData.getAll('files[]'))
// Then send to php with jquery, axios e.t.c
console.log('Server response')
$.post('/pathtophpscript', formData, (response) => {
console.log(response)
}).catch(error => console.log(error))
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="file" name="uploads" id="files" onchange="prepareFiles()" multiple>
<br/><br/>
<input type="submit" name="Upload" onclick="uploadFiles()">

CodeIgniter AJAX file upload, $_FILE is empty when upload

Iam writing a script that uploads files via Drag and Drop using jQuery which reads the file on drop and adds it to an array of files like so:
var files = [];
$(document).ready(function() {
jQuery.fn.dropbox = function(config) {
var dragging = 0;
var dragEnter = function(e) {
e.stopPropagation();
e.preventDefault();
dragging++;
$(".external-drop-indicator").fadeIn();
$(".toast.toast-success").fadeIn().css("display", "inline-block");;
return false;
};
var dragOver = function(e) {
e.stopPropagation();
e.preventDefault();
return false;
};
var dragLeave = function(e) {
e.stopPropagation();
e.preventDefault();
dragging--;
if(dragging === 0) {
$(".external-drop-indicator").fadeOut();
$(".toast.toast-success").fadeOut();
}
return false;
};
var drop = function(e) {
var dt = e.dataTransfer;
var files_upload = dt.files;
e.stopPropagation();
e.preventDefault();
if(files_upload && files_upload.length > 0 && config.onDrop !== undefined) {
files.push(files_upload);
config.onDrop(files_upload);
}
$(".external-drop-indicator").fadeOut();
$(".toast.toast-success").fadeOut();
};
var applyDropbox = function(dropbox) {
dropbox.addEventListener('dragenter', dragEnter, false);
dropbox.addEventListener('dragover', dragOver, false);
dropbox.addEventListener('dragleave', dragLeave, false);
dropbox.addEventListener('drop', drop, false);
};
return this.each(function() {
applyDropbox(this);
});
};
});
In summary what it does is, adds an extended jQuery function to enable drag and drop on a certain element of the website in which the function is applied.
Then I apply the extended functionality to the body for it to enable the file Drag and Drop functionality like so:
$(document).ready(function() {
$('body').dropbox({
onDrop: function(f) {
$(f).each(function(idx, data) {
var file_name = data.name;
var extension = file_name.split('.');
file_name = extension[0];
extension = extension[1];
if(extension == 'pdf' || extension == 'xls') {
showAjaxModal(base_url + 'index.php?modal/popup/file_create/' + folder_id + '/' + extension + '/' + file_name);
} else {
$(".upload-area").append('<div class="alert alert-danger" style="display:inline-block;width:480px;"><strong>Error!</strong> File type is incorrect.</div>');
}
});
}
});
});
In summary what this does is adds the Drag and Drop functionality to the body and when a file is dropped it detects the extension of the file by splitting the name and the extension, so that I can verify that the extension of the file that was dropped is correct. Then it proceeds to show a modal to fill information about the file that is being uploaded for later submission, if the file extension is correct.
Then I proceed to fill the file information using CodeIgniter's function "form_open()" when the modal pops like so:
<?php echo form_open(base_url() . 'index.php?client/file/create/' . $param2, array('class' => 'form-horizontal form-groups-bordered validate ajax-upload', 'enctype' => 'multipart/form-data')); ?>
<div class="col-md-4 file-info">
<div class="icon-<?=($param3 == 'pdf' ? 'pdf' : 'document')?>"></div>
<p>
<?php echo $param4;?>
</p>
</div>
<div class="col-md-8 new-file">
<div class="form-group">
<div class="col-sm-12">
<div class="input-group">
<input type="text" class="form-control" name="tags" data-validate="required" data-message-required="Field is required" placeholder="File tags" value="" autofocus>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<div class="input-group">
<input type="text" class="form-control" name="name" data-validate="required" data-message-required="Field is required" placeholder="File name" value="" autofocus>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-12">
<div class="input-group">
<textarea rows="5" class="form-control" name="description" data-validate="required" data-message-required="Field is required" placeholder="File description" value="" autofocus></textarea>
</div>
</div>
</div>
</div>
<div class="form-group">
<div class="col-sm-offset-4 col-sm-7">
<button type="submit" class="btn btn-info" id="submit-button">Upload</button>
<span id="preloader-form"></span>
</div>
</div>
<?php echo form_close(); ?>
This basically creates a form which later will be submitted via Ajax.
Now I proceed to handle the file submission via jQuery for the information to be sent with the file or files that are being uploaded like so:
$(document).ready(function(e) {
$('.ajax-upload').submit(function(e) {
e.preventDefault();
var $elm = $(this);
var fd = new FormData();
for(var i = 0; i < files.length; i++) {
fd.append("file_" + i, files[i]);
}
var form_data = $(".ajax-upload").serializeArray();
$.each(form_data, function(key, input) {
fd.append(input.name, input.value);
});
var opts = {
url: $elm.attr('action'),
data: fd,
cache: false,
contentType: false,
processData: false,
type: 'POST',
beforeSend: uValidate,
success: showResponse
};
if(fd.fake) {
opts.xhr = function() {
var xhr = jQuery.ajaxSettings.xhr();
xhr.send = xhr.sendAsBinary;
return xhr;
}
opts.contentType = "multipart/form-data; boundary=" + fd.boundary;
opts.data = fd.toString();
}
jQuery.ajax(opts);
return false;
});
});
Basically the form default action is overwritten and the files that were submitted on the previous code chunk for the drag and drop functionality are now appended to formData which later gets joined by the form data that was on the form I submit. Then the formData is sent via an AJAX call.
Now the controller looks like this, it handles the AJAX call and then executes the File Upload method on the model like so:
function file($param1 = '', $param2 = '', $param3 = 0) {
if ($this->session->userdata('client_login') != 1) {
$this->session->set_userdata('last_page', current_url());
redirect(base_url(), 'refresh');
}
if ($param1 == 'create')
$this->crud_model->create_file($param2);
if ($param1 == 'edit')
$this->crud_model->update_file($param2);
if ($param1 == 'delete')
$this->crud_model->delete_file($param2, $param3);
$page_data['page_name'] = 'files';
$page_data['page_title'] = 'Files List';
$page_data['folder_id'] = $param3;
$this->load->view('backend/index', $page_data);
}
Here is the model method:
function create_file($folder_id) {
$data['name'] = $this->input->post('name');
$data['tags'] = $this->input->post('tags');
$data['description'] = $this->input->post('description');
$data['type'] = 'file';
$data['folder_id'] = $folder_id;
$data['client_id'] = $this->session->userdata('login_user_id');
$config['upload_path'] = 'uploads/tmp/';
$config['allowed_types'] = '*';
$config['max_size'] = '100';
$this->load->library('upload');
$this->upload->initialize($config);
var_dump($_FILES);
die();
foreach($_FILES as $field => $file)
{
//var_dump($_FILES); die();
// No problems with the file
if($file['error'] == 0)
{
// So lets upload
if ($this->upload->do_upload($field))
{
$data = $this->upload->data();
echo $data['full_path'];
}
else
{
$errors = $this->upload->display_errors();
var_dump($errors);
}
}
}
$this->db->insert('client_files' , $data);
}
So basically what happens is that the $_FILES array is empty, and the file doesn't get uploaded.
The "Request Payload" as viewed on Chrome's Developer Tools looks like this:
------WebKitFormBoundaryvVAxgIQd6qU8BtkF
Content-Disposition: form-data; name="file_0"
[object FileList]
------WebKitFormBoundaryvVAxgIQd6qU8BtkF
Content-Disposition: form-data; name="tags"
bsd
------WebKitFormBoundaryvVAxgIQd6qU8BtkF
Content-Disposition: form-data; name="name"
asd
------WebKitFormBoundaryvVAxgIQd6qU8BtkF
Content-Disposition: form-data; name="description"
asd
And the response I get from the var_dump() on the model is the following:
array(0) {
}
I have tried the solution on this question: Sending multipart/formdata with jQuery.ajax But no luck so far.
Any idea on what am I doing wrong and how to fix this issue? Thanks.

The problem here is that I'm sending the array of files instead of the single files on the AJAX call, specifically in this part of the code:
for(var i = 0; i < files.length; i++) {
fd.append("file_" + i, files[i]);
}
The solution was to append file by file to the formData instead of the array of files, something like this:
for(var i = 0; i < files[0].length; i++) {
fd.append("file_" + i, files[i]);
}
This will append every single file of the files array instead of the array of files itself and it solves the problem.
In conclusion I was sending the array of files instead of the single files, the clue to this was the [object FileList] that the request was showing instead of the files information, which now makes a request like this:
Content-Disposition: form-data; name="file"; filename="exfile.pdf"
Content-Type: application/pdf
