Laravel Submitting form with same input name ajax

I need help with my ajax function. I have a form that submits data with the same input name
When I run my code without javascript, I can insert multiple input data with the same name,
Submitted structure
{"_token":"CepbQkKwKziSRwDJKuqlEa5i4E21Y5jvSbmDNvqu","id":"7","service_name":["asfd","safd"]}
When I implement javascript, a concatenated string is sent to the controller and this makes the service_name inaccessible.
formdata:"_token=CepbQkKwKziSRwDJKuqlEa5i4E21Y5jvSbmDNvqu&id=7&service_name%5B%5D=sdfg&service_name%5B%5D=gfds&_token=CepbQkKwKziSRwDJKuqlEa5i4E21Y5jvSbmDNvqu&id=8&_token=CepbQkKwKziSRwDJKuqlEa5i4E21Y5jvSbmDNvqu&id=9&_token=CepbQkKwKziSRwDJKuqlEa5i4E21Y5jvSbmDNvqu&id=10&_token=CepbQkKwKziSRwDJKuqlEa5i4E21Y5jvSbmDNvqu&id=11&_token=CepbQkKwKziSRwDJKuqlEa5i4E21Y5jvSbmDNvqu&id=18"
My javascript function
jQuery("form.ajax").on("submit", function (e) {
e.preventDefault();
jQuery.ajax({
url: "/admin/adminpanel/insertService/",
type: "post",
data: {
formdata: $(".ajax#servicesForm").serialize()
},
dataType: "JSON",
success: function (response) {
console.log(response);
},
error: function (jqXHR, exception) {
var msg = "";
if (jqXHR.status === 0) {
msg = "Not connect.\n Verify Network.";
} else if (jqXHR.status === 404) {
msg = "Requested page not found. [404]";
} else if (jqXHR.status === 500) {
msg = "Internal Server Error [500].";
} else if (exception === "parsererror") {
msg = "function Requested JSON parse failed.";
} else if (exception === "timeout") {
msg = "Time out error.";
} else if (exception === "abort") {
msg = "Ajax request aborted.";
} else {
msg = "Uncaught Error.\n" + jqXHR.responseText;
}
}
});
});
My PHP Controller Function
public function insert(Request $request)
{
return response()->json($request);
}

use FormData Object, to send fromdata
fd = new FormData();
fd.append("input-name", value1);
fd.append("input-name2", value2 OR arry of value);
jQuery.ajax({
url: "/admin/adminpanel/insertService/",
type: "post",
data: {
formdata: fd
}

I found a workaround:
First, I created an array, and pushed all instances of input[name='service_name[]'] into the array.
Then I passed the data with ajax and was able to insert the data.
var serviceArray = new Array(), id;
jQuery.map($("input[name='service_name[]']"), function(obj, index) {
serviceArray.push($(obj).val());
});
My ajax script then:
jQuery.ajax({
url: "/admin/adminpanel/insertService/",
type: 'post',
data: {
'service_name': serviceArray,
'id': id
},
dataType: 'JSON',
success: function(response) {
console.log(response);
}
});

Passing A Single Objects Into An MVC Controller Method Using jQuery Ajax

I'm trying to post a single object data to an MVC Controler using JQuery, Below are my codes.
//declare of type Object of GroupData
var GroupData = {};
//pass each data into the object
GroupData.groupName = $('#groupName').val();
GroupData.narration = $('#narration').val();
GroupData.investmentCode = $('#investmentCode').val();
GroupData.isNew = isNewItem;
//send to server
$.ajax({
url: "/Admin/SaveContributionInvestGroup",
type: "POST",
contentType: "application/json;charset=utf-8",
dataType: "json",
data: JSON.stringify({ GroupData: JSON.stringify(GroupData) }),
success: function (res) {
alertSuccess("Success", res.Message);
//hide modal
$('#product-options').modal('hide');
hide_waiting();
},
error: function (res) {
alertError("Error", res.Message);
}
});
Below is my controller.
[HttpPost]
public JsonResult SaveContributionInvestGroup(ContributionInvestmentGroup GroupData)
{
ClsResponse response = new ClsResponse();
ClsContributionInvestmentGroup clsClsContributionInvestmentGroup = new ClsContributionInvestmentGroup();
var userID = (int)Session["userID"];
var sessionID = (Session["sessionID"]).ToString();
if (contributionGroupData != null)
{
//get the data from the cient that was passed
ContributionInvestmentGroup objData = new ContributionInvestmentGroup()
{
contributionInvestmentGroupID = 0,
groupName = GroupData.groupName,
narration = GroupData.narration,
investmentCode = GroupData.investmentCode,
isNew = GroupData.isNew
};
response = clsClsContributionInvestmentGroup.initiateNewContributionInvestmentGroup(sessionID, objData);
}
else
{
response.IsException = true;
response.IsSucess = false;
response.Message = "A system exception occurred kindly contact your Administrator.";
}
return Json(new
{
response.IsSucess,
response.Message
});
}
The issue is, the data is not been posted to the controller, the controller receives a null object.
Kindly assist, would really appreciate your effort, thanks.

Try Like this:
//send to server
$.ajax({
type: "POST",
url: "/Admin/SaveContributionInvestGroup",
dataType: "json",
data: GroupData,
success: function (res) {
alertSuccess("Success", res.Message);
//hide modal
$('#product-options').modal('hide');
hide_waiting();
},
error: function (res) {
alertError("Error", res.Message);
}
});

in your controller your dont have custom binding to bind JSON to your model thats why you get null in you parameter.
instead just post it as query, try simply changes your ajax option like so:
{
...
contentType: "application/x-www-form-urlencoded", //default:
...,
data: $.param(GroupData),
...
}
and perhaps property names are case sensitive so you will need to change your javascript model's name

How do I send files via jQuery AJAX with multiple parameter to an MVC controller?

enter code hereI have read several answers about this question, but no one works.
I have the following code but my HttpPostedFileBase[] array is always null.
The Other parameters has the right value, but the HttpPostedFileBase[] is always null.
What am i missing??
$('#myFile').on('change', function (e) {
var fileName = e.target.files[0].name;
archivosProcesar = new FormData();
for (var i = 0; i <= e.target.files.length -1; i++) {
archivosProcesar.append(i, e.target.files[i]);
}
});
function aplicarFragmentacion() {
var ids = obtenerAfiliadosSeleccionados();
var data = {
fragmento1: parseInt($('#fragmento1').val()),
fragmento2: parseInt($('#fragmento2').val()),
segmentos: ids,
archivos: archivosProcesar
}
if (!validarProcentajes() & !validarSeleccionados(ids)) {
$.ajax({
data: data,
url: urlAplicarFrag,
type: 'POST',
processData: false,
beforeSend: function () {
//$("#resultado").html("Procesando, espere por favor...");
},
success: function (data) {
onSuccessAplicarFragmentacion(data);
},
error: function (jqXHR, textStatus, errorThrown) {
console.log(jqXHR.responseText);
onError(jqXHR.responseText);
}
});
}
}
Controller.cs
public async Task<ActionResult> AplicarFragmentacion(decimal fragmento1, decimal fragmento2, string[] segment\
os, HttpPostedFileBase[] archivos)
{
List<Credito> lstSegmentos = new List<Credito>();
try
{
ProgressHub.SendMessage("Iniciando proceso de fragmentación...", 10);
lstSegmentos = await FragmentacionNegocio.AplicarFragmentacion(fragmento1, fragmento2, segmentos)\
;
}
catch (Exception ex)
{
throw new Exception(ex.Message);
}
return Json(lstSegmentos, JsonRequestBehavior.AllowGet);
}

Try submitting a FormData object, not an anonymous object with a FormData field. Also it is my understanding that the contentType should be set to false.
var formData = new FormData();
formData.append('fragmento1', parseInt($('#fragmento1').val());
formData.append('fragmento2', parseInt($('#fragmento2').val());
formData.append('segmentos', obtenerAfiliadosSeleccionados());
formData.append('archivos', $('#fileupload')[0].files[0]);
$.ajax({
type: 'POST',
data: formData,
url: urlAplicarFrag,
type: 'POST',
processData: false,
contentType: false,
[...]
});

The fix was to use this plug in
https://jquery-form.github.io/form/
In this way
$(this).ajaxSubmit({
url: urlAplicarFrag,
data: {
fragmento1: parseInt($('#fragmento1').val()),
fragmento2: parseInt($('#fragmento2').val()),
segmentos: ids,
fechaReenvio: $('#fecha-reenvio').val()
},
success: function (data) {
onSuccessAplicarFragmentacion(data);
},
error: function (jqXHR, textStatus, errorThrown) {
console.log(jqXHR.responseText);
onError(jqXHR.responseText);
}
});

JQuery TypeError: Converting circular structure to JSON in MVC

Facing error on JSON.stringify(ApplObj) :
How to post this object to controller
JQuery Code -
var ApplName = $("#ApplicantName").val();
var ApplMobile = $("#ApplicantMobile").val();
var ApplEmail = $("#ApplicantEmailId").val();
var ApplFHName = $("#ApplicantFHName").val();
var ApplObj = {
ApplicantName: ApplName, ApplicantMobile: ApplMobile, ApplicantEmailId: ApplEmail, ApplFHName: ApplicantFHName
}
$.ajax({
url: '#Url.Action("SaveApplicatDetail", "Dashboard")',
data: JSON.stringify(ApplObj),
dataType: 'json',
type: 'POST',
contentType: "application/json; charset=utf-8",
success: function (data) {
alert(data);
}
});
Controller Code...
this jsonresult used for save records and return value...
this code is working in other project....
public JsonResult SaveApplicatDetail()
{
try
{
var resolveRequest = HttpContext.Request;
TicketMasterModel TMM = new TicketMasterModel();
resolveRequest.InputStream.Seek(0, SeekOrigin.Begin);
string jsonString = new StreamReader(resolveRequest.InputStream).ReadToEnd();
if (jsonString != null)
{
TMM = (TicketMasterModel)js.Deserialize(jsonString, typeof(TicketMasterModel));
}
int TicketId = 0;
using (var db = new UnitOfWork())
{
DAL.tbl_TrnTicketMaster TM = new DAL.tbl_TrnTicketMaster();
TM.ApplicantName = TMM.ApplicantName;
TM.ApplicantMobile = TMM.ApplicantMobile;
TM.ApplicantEmailId = TMM.ApplicantEmailId;
TM.ApplicantFHName = TMM.ApplicantFHName;
TM.FK_CompanyId = 1;
TM.CustomerId = UserSession.UserId;
TM.IsSubmissionLocked = false;
TM.CreatedBy = UserSession.UserId;
db.tbl_TrnTicketMaster.Insert(TM);
TicketId = TM.PK_TicketId;
}
return Json(TicketId, JsonRequestBehavior.AllowGet);
}
catch (Exception)
{
throw;
}
}

basically JSON.stringify turns a Javascript object into JSON text and stores that JSON text in a string.
try this,
var ApplName = $("#ApplicantName").val();
var ApplMobile = $("#ApplicantMobile").val();
var ApplEmail = $("#ApplicantEmailId").val();
var ApplFHName = $("#ApplicantFHName").val();
var ApplObj = {
'ApplicantName': ApplName, 'ApplicantMobile': ApplMobile, 'ApplicantEmailId': ApplEmail, 'ApplFHName': ApplicantFHName
}
$.ajax({
url: '#Url.Action("SaveApplicatDetail", "Dashboard")',
data: JSON.stringify(ApplObj),
dataType: 'json',
type: 'POST',
contentType: "application/json; charset=utf-8",
success: function (data) {
alert(data);
}
});

Problem Resolved -
"JSON.stringify" is used array to convert it.
var ApplName = $("#ApplicantName").val();
var ApplMobile = $("#ApplicantMobile").val();
var ApplEmail = $("#ApplicantEmailId").val();
var ApplFHName = $("#ApplicantFHName").val();
var ApplDetails = {
ApplicantName: ApplName,
ApplicantMobile: ApplMobile,
ApplicantEmailId: ApplEmail,
ApplicantFHName: ApplFHName
}
var ApplObj = { ApplicantDetail: ApplDetails };
$.ajax({
url: '#Url.Action("SaveApplicatDetail", "Dashboard")',
data: JSON.stringify(ApplDetails),
dataType: 'json',
type: 'POST',
contentType: "application/json; charset=utf-8",
success: function (data) {
}
});

oo practice, make function not hard coding, return data after bind change

I want to find a way,give a dom as parameter and get data, from image_preview.
and separate image_preview.model() and image_preivew.on_chage() is event handler
make image_preview reusable not hardcode inside
I espect I will call image_preview pass dom in parameter, and return src as response , then I can use repsponse do something like append ...
var image_preview = {
on_change: function(wrap_dom, input_dom) {
$(wrap_dom).on('change', input_dom, function(event) { // I have to use on change because there are possible the `input dom` is new append...
var el_obj = $(this)[0];
var form_data = new FormData();
var file_length = el_obj.files.length;
for (var i = 0; i < file_length; i++) {
form_data.append("file[]", el_obj.files[i]);
}
image_preview.model(form_data).done(function(response) {
// console.log(response); // this is work
return response;
});
});
},
model: function(form_data) {
return $.ajax({
url: uri_public+'/admin/ajax/preview_file',
type: 'POST',
data: form_data,
processData: false,
contentType: false,
// async: false
});
}
}
var app_thumbnail = {
preview_controller: function() {
var wrap_dom = '.thumbnail';
var input_dom = '.upload-form input';
var result = image_preview.on_change(wrap_dom, input_dom);
// pass result to render view like append dom....
},
render: function() {
},
}
app_thumbnail.preview_controller();

Here is the easiest thing you can do:
var image_preview = {
on_change: function(wrap_dom, input_dom) {
$(wrap_dom).on('change', input_dom, function(event) {
var el_obj = $(this)[0];
var form_data = new FormData();
var file_length = el_obj.files.length;
for (var i = 0; i < file_length; i++) {
form_data.append("file[]", el_obj.files[i]);
}
image_preview.model(form_data).done(function(response) {
app_thumbnail.preview_controller(response);
});
});
},
model: function(form_data) {
return $.ajax({
url: uri_public+'/admin/ajax/preview_file',
type: 'POST',
data: form_data,
processData: false,
contentType: false,
// async: false
});
}
}
var app_thumbnail = {
preview_controller: function(response) {
var wrap_dom = '.thumbnail';
var input_dom = '.upload-form input';
var result = response;
}
}
// If you want to initialize it.
// image_preview.on_change(..., ...);
