ส่งค่าจาก form ผ่าน Ajax ไปอีกหน้าเพื่อแสดง datatable

ส่งค่าจาก form ผ่าน Ajax ไปอีกหน้าเพื่อแสดง datatable
จะส่งค่า id_partner จากหน้า showEachCom.php ไปที่หน้า po-grid-data.php
จากหน้า showEachCom.php ถ้าลอง <? echo $_POST['id_partner'];?> ก็มีค่าขึ้นปกติ แต่จะส่งไปหน้า po-grid-data.php มันไม่ไปให้ค่ะ

หน้า index.php
<form id="myForm" action="showEachCom.php" method="post">
	
	<input name="name_partner" type="text" id="name_partner"/>
	<input name="id_partner" type="hidden" id="id_partner"/>
	<input type="submit" name="submit" id="submit" value="submit">
	<br/><br/>
	<div id="showdata">
		<?/* if($_POST['submit'])
		{  include('showEachCom.php');} */?>
  </div>
  </form>

    var data2 = "<? echo $_POST['id_partner'];?>";
    "ajax":{
        url :"po-grid-data.php", // json datasource
        type: "post",  // method  , by default get
        data: data2,
        error: function(){  // error handling
            $(".employee-grid-error").html("");
            $("#employee-grid").append('<tbody class="employee-grid-error"><tr><th colspan="3">No data found in the server</th></tr></tbody>');
            $("#employee-grid_processing").css("display","none");
             
        }
    },
 
เอาโค้ดไปแทรกในลักษณะแบบนี้น่าจะ error หรือป่าว
ลองใช้แบบนี้ดู
 
    "ajax":{
        url :"po-grid-data.php", // json datasource
        type: "post",  // method  , by default get
        data: {
        	data2:<? echo $_POST['id_partner'];?>
        }
    },    
 
ส่วนของการจัดการ error ไม่แน่ใจว่าใช้ได้ไหม แต่ปกติ ไม่น่าจะต้องมี เพราะถ้าไม่มีข้อมูล dataTable
ก็จะแสดงข้อความให้เองว่าไม่พบข้อมูล เราไม่ต้องกำหนดอะไร

เหมือนว่ามันไม่ไปให้อ่ะค่ะ
หน้า showEachCom.php
 "ajax":{
						url :"po-grid-data.php", // json datasource
						type: "post",  // method  , by default get
						data: { data2: <? echo $_POST['id_partner'];?>  }
						error: function(){  // error handling
							$(".employee-grid-error").html("");
							$("#employee-grid").append('<tbody class="employee-grid-error"><tr><th colspan="3">No data found in the server</th></tr></tbody>');
							$("#employee-grid_processing").css("display","none");
							
						}
					},
เป็นเพราะหน้า po-grid-data.php มันมีข้อมูลdata อยู่แล้วหรือเปล่าคะ 
$json_data = array(
			"draw"            => intval( $requestData['draw'] ),   // for every request/draw by clientside , they send a number as a parameter, when they recieve a response/data they first check the draw number, so we are sending same number in draw. 
			"recordsTotal"    => intval( $totalData ),  // total number of records
			"recordsFiltered" => intval( $totalFiltered ), // total number of records after searching, if there is no searching then totalFiltered = totalData
			"data"            => $data   // total data array
			);

echo json_encode($json_data);  // send data as json format

ได้แล้วค่ะ หนูส่งเป็นค่า GET ไปแทน
  "ajax":{
						url: "po-grid-data.php?id_partner="+<? echo $_POST['id_partner'];?>,// json datasource
						type: "post",  // method  , by default get
						error: function(){  // error handling
							$(".employee-grid-error").html("");
							$("#employee-grid").append('<tbody class="employee-grid-error"><tr><th colspan="3">No data found in the server</th></tr></tbody>');
							$("#employee-grid_processing").css("display","none");
							
						}
					},
ขอบคุณนะคะ
