Ajax form content and insert into DB with Laravel .. - ajax

Question

i created a form using AJAX because i have several alternatives concerning the fields.
I have correct information in my javascript and make tests... my first select use the following function and generates form
function setParentSector() {
$("#listSectors").html("");
$("#createSector").html("");
if($('#langname option:selected').val() !=0) {
var obj = { 'id': $('#langname option:selected').val() };
if (obj['id'] != 1) {
ajaxSectors(obj);
}
else
{
// another form generated here ...
$('#createSector').append("something else");
}
}
};
I use a "classical" ajax ..
function ajaxSectors(objSetParent) {
$.ajax({
headers: {
'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
},
url: '/admin/ajax/sectorParent',
type: 'post',
dataType: 'json',
async: true,
success: function (result) {
$('#listSectors').append("<label for='langname'>label </label> " +
"<select class='form-control m-input m-input--air' id='sectors' onclick='setLangTranslation()'>" +
"<option value='0' selected>Select value</option></select>" +
"<span class='m-form__help' id='existsAlready'>");
var count = result.length;
for (var i = 0; i < count; i++) {
if (result[i].deleted_at === null) {
$('#sectors').append("<option value='" + result[i].sector_id + "'>" + result[i].sectname + "</option>");
}
else {
console.log("peanuts");
}
}
},
data:objSetParent,
error: function (result) {
},
complete: function (result) {
//console.log("complete");
}
});
}
This part of code works fine and i display what i want...
When I want to save into DB the form, I plan to use the store method and I create the $request->validate()
In the store method I have :
$request->validate([
'admin' => 'required',
'langname' => 'required',
'sectname' => 'required',
'sectshortname' => 'nullable',
]);
return view ('test')
The test view contains just in order to see what i post ..
If i keep the validate part, the page is just refreshed and not validated...
Without the request validate I display the view and i just see the value of the input with the token.
Thanks for your answers. Let's hope my question is "clear" enough

Use this code I hope this code works for you please use this Use Validator;
$rules = [
'admin' => 'required',
'langname' => 'required',
'sectname' => 'required',
'sectshortname' => 'nullable',
];
$data = $request->all();//or you can get it by one by one
$validator = Validator::make($data , $rules);
if ($validator->fails()) {
$error=[];
$errors = $validator->messages();
foreach($errors->all() as $error_msg){
$error[]= $error_msg;
}
return response()->json(compact('error'),401);
}
return view ('test')
