Server side code fails to serve me as expected

mohsin007

Hello all.
I have an 46000 records in my database table whom i want to handle using datatable server side code. I did implement the code as well but i am not sure why it is not working all the way to me. can anybody please help me?
Here is my function:

<link href="http://cdn.datatables.net/1.10.0/css/jquery.dataTables.css" rel="stylesheet" type="text/css" />

$(document).ready(function() { $('#rounded-corner').dataTable( { "processing": true, "serverSide": true, "iDisplayLength": 50, "ajax": "<?php echo WEB_URL; ?>assets/common/authorsServerSide.php" } ); } );

Here is my table:

<?php $count = 1; while($AuthorRecs = $RecordSet->fetch_object()){?> <?php } ?>

Sr No.	Author Name	Birth Year	Death Year	Action
<?php echo $count++; ?>	<?php print stripslashes(html_entity_decode($AuthorRecs->a_name)); ?>	<?php print $AuthorRecs->a_birth; ?>	<?php print $AuthorRecs->a_death; ?>	a_ID; ?>">	a_ID; ?>" class="ask">
