php - pass a data key value from a json post request to routes to controller -

my json post request has data key named "id", how im going pass routes controller?

my json post request

$.post("/employees", {id:"1"}, function(response){ if(response.success) {     var branchname = $('#branchname').empty();     $.each(response.employees, function(){         $('<option/>', {             value:$(this).user_no,             text:$(this).firstname         }).appendto(branchname);     }); } }, 'json'); 

as can see json post request have put key value name id

my routes

route::post('employees', [     'as' => 'employees', 'uses' => 'mot@getemployee' ]); 

and controller

public function getemployee($id){         $employees = employees::where("branch_no", $id)->lists('firstname', 'user_no');         return response()->json(['success' => true, 'employees' => $employees]); } 

as can see, have argument $id, supposedly, key value named id json post request put , used query stuff.

since you're using $.post in jquery code, {id: ...} parameter passed post data, means instead of having:

public function getemployee($id){ 

you should have:

public function getemployee() {  $id = (int)$_post['id']; //notice int casting 

@khanshahrukh has point. consider using following instead of traditional post variable:

<?php  namespace app\http\controllers; use request; .... .... class ... extends ... {   public function ...() {     if(request::ajax()) { //prevent direct access       $id = request::input('id;); 

regarding second issue (which mentioned in comment), $(this) won't refer object. in order access object's properties, should add parameters function() in $.each function. (manual)

so instead of:

$.each(response.employees, function(){     $('<option/>', {         value:$(this).user_no,         text:$(this).firstname 

you should have:

$.each(response.employees, function(firstname, user_no){     $('<option/>', {         value: user_no,         text: firstname
