مشكلة في ارسال البيانات لقاعدة البيانات

السلام عليكم

لدي كودين لجدولين عند ارسال بيانات للقاعدة من الاول تخزن بنجاح لكن عند ارسال بيانات من الثاني لا تخزن في الثاني بل تخزن في الاول في صورة  undefined

الجدول الاول saturday_one_primary_schedule

CREATE TABLE `saturday_one_primary_schedule` (
`ador_schedule` varchar(50) NOT NULL,
`teacher` varchar(50) NOT NULL,
`subject` varchar(50) NOT NULL,
`aclass` varchar(50) NOT NULL,
`together` varchar(50) NOT NULL
)ENGINE=INNODB DEFAULT CHARSET=utf8;

الجدول الثانيsaturday_two_primary_schedule

CREATE TABLE `saturday_two_primary_schedule` (
`ador_schedule` varchar(50) NOT NULL,
`teacher` varchar(50) NOT NULL,
`subject` varchar(50) NOT NULL,
`aclass` varchar(50) NOT NULL,
`together` varchar(50) NOT NULL
)ENGINE=INNODB DEFAULT CHARSET=utf8;

الكود الاول

$("#submit").click(function(){
var subject = $("#subject").val();
var aclass = $("#aclass").val();

var dataString = 'subject='+ subject + '&aclass='+ aclass + '&together='+ together ;
if(aclass=='<?php while($row=$result->fetch_assoc()):?><?=$row['aclass']?><?php endwhile;?>')
{
alert("لا يمكن ادخال فصلبن متشابهين في نفس الحصة");
}
else
{
$.ajax({
type: "POST",
url: "schedule_primary/send/send_saturday_one.php?send_saturday_one=<?=$_GET['teacher_schedule'] ?>",
data: dataString,
cache: false,
success: function(result){

}
});
}
return false;
