I want to upload multiple files using onchange in laravel 8. is it possible to upload just by onchange? I have this html form. I hope you can help me guys. thanks
<form method="POST" enctype="multipart/form-data" id="upload_form">
#csrf
<input type="file" name="file[]" id="file" multiple >
</form>
this is my Jquery and Ajax Script.
<script>
function uploadfile(){
var formData = new FormData($('#upload_form')[0]);
$.ajaxSetup({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
}
});
$.ajax({
type:'POST',
url: "{{ route('dropzone-action') }}",
data: formData,
contentType: false,
processData: false,
success: (response) => {
if (response) {
this.reset();
alert('Image has been uploaded successfully');
}
},
error: function(response){
console.log(response);
$('#image-input-error').text(response.responseJSON.errors.file);
}
});
}
and here is my controller
function action(Request $request){
$request->validate([
'file' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
if($request->hasFile('file')){
foreach($request->file as $file) {
$completeFileName = $file->getClientOriginalName();
$fileNameOnly = pathinfo($completeFileName, PATHINFO_FILENAME);
$extension = $file->getClientOriginalExtension();
$file->storeAs('uploads', $completeFileName);
}
}
return response()->json('Image uploaded successfully');
}
You can call change method
$("#file").change(function() {
uploadfile();
});
and in validation
$request->validate([
'file.*' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
and in controller
function action(Request $request){
$request->validate([
'file.*' => 'required|image|mimes:jpeg,png,jpg,gif,svg|max:2048',
]);
foreach($request->file as $file) {
if($file!=null){
$completeFileName = $file->getClientOriginalName();
$fileNameOnly = pathinfo($completeFileName, PATHINFO_FILENAME);
$extension = $file->getClientOriginalExtension();
$file->storeAs('uploads', $completeFileName);
}
}
return response()->json('Image uploaded successfully');
}
I've seen and tried a few answers that are similar to this question, but it still displays the same error.
The console is also giving the error: Uncaught TypeError: Cannot read property 'length' of undefined at Function.each (jquery-1.10.2.js:631)
My view:
<form action="https://dev.vmc.w3.uvm.edu/xana/sensors/deployments" class="basicForm aboutForm form-horizontal" id="deploymentForm" enctype="multipart/form-data" method="post" accept-charset="utf-8">
<div class="form-group">
<label for="fldFileName" class="col-sm-4 control-label">Image</label>
<div class="col-sm-8">
<input type="file" name="fldFileName" value="" class="form-control" id="fldFileName" />
</div>
</div>
<button type="button" class="btn btn-primary" id="newSensorSubmit">Save</button>
</form>
javascript to submit form:
$(document).on("click", "#newSensorSubmit", function(event){
var posturl="<?php echo site_url("sensors/add_deployment");?>";
var formData = new FormData();
var fldFileName = $('#fldFileName').val();
formData.append('fldFileName', fldFileName);
jQuery.ajax({
url: posturl,
data: formData,
cache: false,
mimeType: "multipart/form-data",
dataType: 'json',
contentType: false,
processData: false,
type: 'POST',
success: function(data){
if(data.status === 'success') {
//handle success
}
else {
//handle fail
}
},
error: (error) => {
$('#articleErrorText').html(JSON.stringify(error));
}
});
});
controller:
public function add_deployment(){
$this->load->helper(array('form', 'url'));
$this->load->library('upload');
$config = array(
'upload_path' => site_url("attachments/project/999/metstations"),
'allowed_types' => "gif|jpg|png|jpeg",
'overwrite' => TRUE,
'max_size' => "16000000"
);
$this->load->library('upload', $config);
if($this->upload->do_upload('fldFileName'))
{
$data['image_metadata'] = array('image_metadata' => $this->upload->data());
}
else
{
$error = $this->upload->display_errors();
$data['errors']='<p class="error-message">'.$error.'</p>';
$data['status']='failure';
}
}
Try This.
To get all your form inputs, including the type="file" you need to use FormData object.
To append param just use append() method:
formData.append("param", "value");
And in the php-side I catch it:
echo $file_name = ($_FILES['file']['name']);
View Code:-
<body>
<p id="msg"></p>
<input type="file" id="file" name="file" />
<button id="upload">Upload</button>
</body>
jQuery / Ajax Code:-
<script type="text/javascript" src="https://code.jquery.com/jquery-3.4.1.min.js"></script>
<script type="text/javascript">
$(document).ready(function(e){
$('#upload').on('click', function () {
var file_data = $('#file').prop('files')[0];
var form_data = new FormData();
form_data.append('file', file_data);
$.ajax({
url: 'ControllerName/upload_file', // point to server-side controller method
dataType: 'text', // what to expect back from the server
cache: false,
contentType: false,
processData: false,
data: form_data,
type: 'post',
success: function (response) {
$('#msg').html(response); // display success response from the server
},
error: function (response) {
$('#msg').html(response); // display error response from the server
}
});
});
});
</script>
Controller Code:-
class ControllerName extends CI_Controller {
function __construct() {
parent::__construct();
}
function upload_file() {
//upload file
$config['upload_path'] = 'uploads/';
$config['allowed_types'] = '*';
$config['max_filename'] = '255';
$config['encrypt_name'] = TRUE; // remove it for actual file name.
$config['max_size'] = '1024'; //1 MB
if (isset($_FILES['file']['name'])) {
if (0 < $_FILES['file']['error']) {
echo 'Error during file upload' . $_FILES['file']['error'];
} else {
if (file_exists('uploads/' . $_FILES['file']['name'])) {
echo 'File already exists : uploads/' . $_FILES['file']['name'];
} else {
$this->load->library('upload', $config);
if (!$this->upload->do_upload('file')) {
echo $this->upload->display_errors();
} else {
echo 'File successfully uploaded : uploads/' . $_FILES['file']['name'];
}
}
}
} else {
echo 'Please choose a file';
}
}
}

I have a form with two input text and one upload. I have to send it to the server but I have some problem concatenating the file with the text. The server expects this answer:
"title=first_input" "text=second_input" "file=my_file.pdf"
This is the html:
<input type="text" ng-model="title">
<input type="text" ng-model="text">
<input type="file" file-model="myFile"/>
<button ng-click="send()">
This is the Controller:
$scope.title = null;
$scope.text = null;
$scope.send = function(){
var file = $scope.myFile;
var uploadUrl = 'my_url';
blockUI.start();
Add.uploadFileToUrl(file, $scope.newPost.title, $scope.newPost.text, uploadUrl);
};
This is the Directive fileModel:
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};
And this is the Service which call the server:
this.uploadFileToUrl = function(file, title, text, uploadUrl){
var fd = new FormData();
fd.append('file', file);
var obj = {
title: title,
text: text,
file: fd
};
var newObj = JSON.stringify(obj);
$http.post(uploadUrl, newObj, {
transformRequest: angular.identity,
headers: {'Content-Type': 'multipart/form-data'}
})
.success(function(){
blockUI.stop();
})
.error(function(error){
toaster.pop('error', 'Errore', error);
});
}
If I try to send, I get Error 400, and the response is: Multipart form parse error - Invalid boundary in multipart: None.
The Payload of Request is: {"title":"sadf","text":"sdfsadf","file":{}}
Don't serialize FormData with POSTing to server. Do this:
this.uploadFileToUrl = function(file, title, text, uploadUrl){
var payload = new FormData();
payload.append("title", title);
payload.append('text', text);
payload.append('file', file);
return $http({
url: uploadUrl,
method: 'POST',
data: payload,
//assign content-type as undefined, the browser
//will assign the correct boundary for us
headers: { 'Content-Type': undefined},
//prevents serializing payload. don't do it.
transformRequest: angular.identity
});
}
Then use it:
MyService.uploadFileToUrl(file, title, text, uploadUrl).then(successCallback).catch(errorCallback);
Here is the complete solution
html code,
create the text anf file upload fields as shown below
<div class="form-group">
<div>
<label for="usr">User Name:</label>
<input type="text" id="usr" ng-model="model.username">
</div>
<div>
<label for="pwd">Password:</label>
<input type="password" id="pwd" ng-model="model.password">
</div><hr>
<div>
<div class="col-lg-6">
<input type="file" file-model="model.somefile"/>
</div>
</div>
<div>
<label for="dob">Dob:</label>
<input type="date" id="dob" ng-model="model.dob">
</div>
<div>
<label for="email">Email:</label>
<input type="email"id="email" ng-model="model.email">
</div>
<button type="submit" ng-click="saveData(model)" >Submit</button>
directive code
create a filemodel directive to parse file
.directive('fileModel', ['$parse', function ($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var model = $parse(attrs.fileModel);
var modelSetter = model.assign;
element.bind('change', function(){
scope.$apply(function(){
modelSetter(scope, element[0].files[0]);
});
});
}
};}]);
Service code
append the file and fields to form data and do $http.post as shown below
remember to keep 'Content-Type': undefined
.service('fileUploadService', ['$http', function ($http) {
this.uploadFileToUrl = function(file, username, password, dob, email, uploadUrl){
var myFormData = new FormData();
myFormData.append('file', file);
myFormData.append('username', username);
myFormData.append('password', password);
myFormData.append('dob', dob);
myFormData.append('email', email);
$http.post(uploadUrl, myFormData, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
})
.error(function(){
});
}
}]);
In controller
Now in controller call the service by sending required data to be appended in parameters,
$scope.saveData = function(model){
var file = model.myFile;
var uploadUrl = "/api/createUsers";
fileUpload.uploadFileToUrl(file, model.username, model.password, model.dob, model.email, uploadUrl);
};
You're sending JSON-formatted data to a server which isn't expecting that format. You already provided the format that the server needs, so you'll need to format it yourself which is pretty simple.
var data = '"title='+title+'" "text='+text+'" "file='+file+'"';
$http.post(uploadUrl, data)
This never gonna work, you can't stringify your FormData object.
You should do this:
this.uploadFileToUrl = function(file, title, text, uploadUrl){
var fd = new FormData();
fd.append('title', title);
fd.append('text', text);
fd.append('file', file);
$http.post(uploadUrl, obj, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
})
.success(function(){
blockUI.stop();
})
.error(function(error){
toaster.pop('error', 'Errore', error);
});
}
Using $resource in AngularJS you can do:
task.service.js
$ngTask.factory("$taskService", [
"$resource",
function ($resource) {
var taskModelUrl = 'api/task/';
return {
rest: {
taskUpload: $resource(taskModelUrl, {
id: '#id'
}, {
save: {
method: "POST",
isArray: false,
headers: {"Content-Type": undefined},
transformRequest: angular.identity
}
})
}
};
}
]);
And then use it in a module:
task.module.js
$ngModelTask.controller("taskController", [
"$scope",
"$taskService",
function (
$scope,
$taskService,
) {
$scope.saveTask = function (name, file) {
var newTask,
payload = new FormData();
payload.append("name", name);
payload.append("file", file);
newTask = $taskService.rest.taskUpload.save(payload);
// check if exists
}
}
Assume that we want to get a list of certain images from a PHP server using the POST method.
You have to provide two parameters in the form for the POST method. Here is how you are going to do.
app.controller('gallery-item', function ($scope, $http) {
var url = 'service.php';
var data = new FormData();
data.append("function", 'getImageList');
data.append('dir', 'all');
$http.post(url, data, {
transformRequest: angular.identity,
headers: {'Content-Type': undefined}
}).then(function (response) {
// This function handles success
console.log('angular:', response);
}, function (response) {
// this function handles error
});
});
I have tested it on my system and it works.
I have an issue with $http in angularjs :
app.controller('ctrlProfil', function($scope, $http){
$scope.loginProfil = "<?= $_SESSION['login']?>";
$scope.mdpProfil = "<?= $_SESSION['mdp']?>";
$scope.emailProfil = "<?= $_SESSION['email']?>";
var config = {
method: 'POST',
url: 'modifProfil.php',
data: $('#formProfil').serialize()
}
$scope.submit = function(){
$http(config).
then(function(response){
console.log(response);
console.log($('#formProfil').serialize());
})
}
});
my form =>
<form id="formProfil" ng-submit="submit()">
<p><span>Bonjour </span><input type="text" name="loginProfil" value="{{loginProfil}}"/></p>
<p>Mon mot de passe: <input type="text" name="mdpProfil" value="{{mdpProfil}}"/></p>
<p> Email: <input type="email" name="emailProfil" value="{{emailProfil}}"/></p>
<input class="btn btn-primary" type="submit" value="Enregistrer"/>
</form>
my php code =>
try
{
$db = new PDO('mysql:host=localhost;dbname=monprojet;charset=UTF8', 'root', 'root');
}
catch(Exception $e)
{
die('Erreur : '.$e->getMessage());
}
$login = $_POST['loginProfil'];
$mdp = $_POST['mdpProfil'];
$email = $_POST['emailProfil'];
$rep = $db->query('SELECT id FROM utilisateur WHERE login='.$_SESSION['login']);
$reponse = $db->prepare('UPDATE utilisateur SET login= :login, mdp= :mdp, email= :email WHERE id='.$rep);
$reponse->execute(array(
':login' => $login,
':mdp' => $mdp,
':email' => $email
));
$json = json_encode($reponse->fetchAll());
$reponse->closeCursor();
echo $json;
i can't manage to send the data via the $http(config), i have an error telling me :
Notice: Undefined index: loginProfil in
/Applications/MAMP/htdocs/izad/git/modifProfil.php on line 15
Notice: Undefined index: mdpProfil in
/Applications/MAMP/htdocs/izad/git/modifProfil.php on line 17
Notice: Undefined index: emailProfil in
/Applications/MAMP/htdocs/izad/git/modifProfil.php on line 19
but my index are defined, need some help to understand this one
Thanks
You have to add headers application/x-www-form-urlencoded to receive the data in GET/POST request in php.
By default, the $http service will transform the outgoing request by
serializing the data as JSON
Change your $http request to this:
var config = {
method: 'POST',
url: 'modifProfil.php',
headers: {'Content-Type': 'application/x-www-form-urlencoded'},
data: $('#formProfil').serialize()
}
$scope.submit = function(){
$http(config).
then(function(response){
console.log(response);
console.log($('#formProfil').serialize());
})
You can also add headers for all $http request like this:
myapp.factory('httpRequestInterceptor', function () {
return {
request: function (config) {
config.headers['Content-Type'] = 'application/x-www-form-urlencoded';
return config;
}
};
});
myapp.config(function ($httpProvider) {
$httpProvider.interceptors.push('httpRequestInterceptor');
});
I'm trying to upload a file through ajax in Laravel.
$("#stepbutton2").click(function(){
var uploadFile = document.getElementById("largeImage");
if( ""==uploadFile.value){
}
else{
var fd = new FormData();
fd.append( "fileInput", $("#largeImage")[0].files[0]);
$.ajax({
url: '/nominations/upload/image',
data: fd,
processData: false,
contentType: false,
type: 'POST',
success: function(data){
if(data.uploaded==true){
alert(data.url);
}
},
error: function(err){
alert(err);
}
});
}
});
I'm passing the file input to the php script.
public function image(){
$file = Input::file('fileInput');
$ext = $file->getClientOriginalExtension();
$fileName = md5(time()).".$ext";
$destinationPath = "uploads/".date('Y').'/'.date('m').'/';
$file->move($destinationPath, $fileName);
$path = $file->getRealPath();
return Response::json(["success"=>true,"uploaded"=>true, "url"=>$path]);
}
I'm getting a the response as
{"success":true,"uploaded":true,"url":false}
The request Payload is
------WebKitFormBoundary30GMDJXOsygjL0ZS
Content-Disposition: form-data; name="fileInput"; filename="DSC06065 copy.jpg"
Content-Type: image/jpeg
Why this is happening?
Found the answer:
public function image(){
$file = Input::file('fileInput');
$ext = $file->getClientOriginalExtension();
$fileName = md5(time()).".$ext";
$destinationPath = "uploads/".date('Y').'/'.date('m').'/';
$moved_file = $file->move($destinationPath, $fileName);
$path = $moved_file->getRealPath();
return Response::json(["success"=>true,"uploaded"=>true, "url"=>$path]);
}
Get the path after assigning it to a new variable.
