Ajax returned an undefined php index error while the other one don't – Jquery ajax

I have a problem with ajax, when I call it, i get the undefined index error on my variables.
I have other ajax call on all my website, and no problem, but this one give me an error.
I search in my code and I don’t see where my mistake is :(.

Here is my HTML :

<script type="text/javascript">

  $('#btnDispo').click(function()
  {
    var service = document.getElementById("serviceTest").value;
    var date = document.getElementById("DateReservation").value;
    var heure = document.getElementById("heureTest").value;
    if( service && date && heure)
    {
        $.ajax({
        type:"POST",
        url: "check-table.php",
        dataType: "json",
        data: 
        {
          service: service, date: date, heure: heure
        },
        success: function(output_string)
        {
          $("#result_table").html(output_string);
        } // End of success function of ajax form
        }); // End of ajax call 
    }
    else
    {
        alert("c'est pas rempli");
    }
  });
</script>

and this is my check-table.php :

<?php
    //DB Connection
    include("connection.php"); 

    $service = isset($_REQUEST['service']) ? $_REQUEST['service'] : 'serviceBug' ;
    $date = isset($_REQUEST['date']) ? $_REQUEST['date'] : 'dateBug' ;
    $heure = isset($_REQUEST['heure']) ? $_REQUEST['heure'] : 'heureBug' ;
    $output_string = "Service = " . $service . " et date = " . $date . " et heure = " . $heure; 
/*
    $tableDispo = "SELECT numTable FROM tbltable WHERE NOT EXISTS (SELECT * FROM tblreservation WHERE tblreservation";
    $tableDispo .=".idTable = tbltable.idTblTable and tblreservation.serviceReservation = '".$service."' and tblreservation.dateReservation = '".$date."' )";
    $result = mysqli_query($con, $tableDispo);

    $output_string = "";
    $output_string .=  "<table border='1'>n";
    while($row = mysqli_fetch_assoc($result))
    {
        foreach($row as $value)
        {
            $id = $row['numTable'];
            $output_string .= "<img width='";
            $output_string .= "90%' src='";
            $output_string .= "../Images/Table";
            $output_string .= $id;
            $output_string .= ".png'>n";
        }
        $output_string .= "</tr>n";
    }
    $output_string .= "</table>n";

    //mysql_close();
    // This echo for jquery */
    echo json_encode($output_string);
?>

I have the same in an another page, who works perfectly :
html :

  <script type="text/javascript" language="javascript">

  $('#btnFiltre').click(function()
  {
    var service = document.getElementById("serviceTest").value;
    var date = document.getElementById("DateReservation").value;
    var heure = document.getElementById("heureTest").value;
    $.ajax({
      url: "check-gestionTable.php",
      type:'POST',
      dataType: 'json',
      data: 
      {
        service: service, date: date, heure: heure
      },
      success: function(output_string)
      {
        $("#result_table").html(output_string);
      } // End of success function of ajax form
    }); // End of ajax call 
  });
</script>

            $output_string .= "</table>n";

            // This echo for jquery 
            echo json_encode($output_string);
        }
   }

?>

The problem doesn’t even is in my php code, just the data don’t go from my html to my php.

    When making an Ajax call, which doesn't post if success, just check that the button that calls ajax, isn't in a form tag.

    Since a $_REQUEST var isn’t being generated, my best guess is that your two HTML pages are using two different versions of jQuery. If that’s the case, you need the new one to use ‘method: "POST"’, not type:. Either way, look into capturing the xhr data from jQuery’s site and log it to the console.
