                   success:function(data){
                       alert(data);

                   }
                });

I tried below code as well.

                $.ajax({
                    url:'registration_detail.php',

                    data: { id: id},
                   success: function(response) {
            $('#result').html(response);
        }
                });

  • You can't mix php and javascript that way. Php runs only on server...not in browser. Read up on how to access url query params using javascript – charlietfl Jul 10 '19 at 23:19

You should fix your code:

<script>

      jQuery.ajax({
                var registration_date=$("#registration_date").val()                    
               var building_length_ft=$("#building_length_ft").val();
                var building_length_in=$("#building_length_in").val();
                var building_breadth_ft=$("#building_breadth_ft").val();
                // There is a PHP script here:
                 var reg_id=<?= $_GET['id'] ?>;
                 var dataString = $('#a').serialize();

                $.ajax({
                    url:'registration_detail.php',
                    method:'POST',
                   data: dataString,
                   success:function(data){
                       alert(data);
                   }
                });
            });

    </script>
