Jquery Ajax get not passing values

Question

This is driving me crazy...

$(document).on("click",".load",function(b){
  b.preventDefault();
  $.get("/url/get.php",{
    id: 123
  },
  function(a){
    $("#result").html(a);
  })
});

This loads the page as expected but when I do print_r($_GET) it shows it's empty... Any ideas?

Backend:

 if (isset($user) == false) {
     session_start();
     $path_to_root = "../";
     require($path_to_root."require/loads.php");
     $PDO = new PDO(DB_CONN, DB_USERNAME, DB_PASSWORD);
     $user = new User($PDO);
 }
 $i = 0;
 print_r($_GET);

It may have something to do with your backend setup. That js looks fine — AmmarCSE, Jun 09 '15 at 09:57

Please, try this way, using done() function:

$(document).on("click",".load",function(b){
  b.preventDefault();
  $.get("/url/get.php",{
    id: 123
  }).done(
  function(a){
    $("#result").html(a);
  })
});

As said in jquery docs that´s the way to send payload data with GET.

Anyway, you can also use ajax:

$.ajax({
  url: "/url/get.php",
  type: "get", //send it through get method
  data:{id:123},
  success: function(response) {
      $("#result").html(a);
  },
  error: function(xhr) {
    $("#result").html("ERROR");
  }
});

Anyway, if you are still viewing those errors, the problem souhld be in your backend as @AmmarCSE commented.

Hope it helps

EDIT some text about the difference between jquery methods success() and done() :

.done() solved the problem... Thank you.It's weird because I've used before without .done() without problems. – Micael Dias Jun 09 '15 at 10:13
$get and $ajax are differente... I also had crazy days with that... :) happy to see you solved!! – Alejandro Teixeira Muñoz Jun 09 '15 at 10:27
I think it´s due to ajax xhr errors. similar to done() there is a success method, that runs when the petition is ok. Done will run always. Adding an edit to clarify – Alejandro Teixeira Muñoz Jun 09 '15 at 10:29

please try this

 $(document).on("click",".load",function(b){
  b.preventDefault();
   $.ajax({
   method:'get',
   url : '/url/get.php', 
   data : '{id:123}',
   dataType: 'json', //json,html any you will return from backend
   success:function(a){
       $("#result").html(a);
     }


   })
 });

Try using $data = file_get_contents("php://input");

$r = json_decode($data);

instead of $_GET in you php file, then print $r
