PHP Form with DataTables Enhancement

Hi,

First i wanted to thank the team for developping such a great tool.

Sorry for long post but i want to be as clear as possible. Here is my problem :I am doing an interface for a user to set criterias through a POST FORM (html+php) and run the slq search into a huge database (millions of rows), then show the results on a table.
I wanted to include the DataTables enhancement, mainly for pagination and sorting.

1) I tried at first to just include datatable into my normal table, here is a sample of the table i used

<table class="display" id="datatables">
				<thead>
					<tr>
					  <th class="resultzone">Order<br />Type</td>
					  <th class="resultzone">Manager<br />Plaque<br />DR</td>
					[......]
					  <th class="resultzone">Error</td>
					</tr>
				</thead>
				<?php
				while ($row = mysql_fetch_array($requestA))
				{
				echo '<tbody>';
					echo '<tr>';
					echo '<td class="cellresultorder">'; 	
								echo $row['main'];	echo '<br />'; 							
								echo $row['order'];
					echo '</td>';
					echo '<td class="cellresult">';			
								echo $row['neman'];	echo '<br />';	
								echo $row['nearea'];echo '<br />';
				[.... rest of table ...]
					echo '<td class="cellresult">';			
								echo $row['errormessage'];
					echo '</td>';
					echo '</tr>';
			  echo '</tbody>';
			  }
			?>
			</table>

Initialization :

<script type="text/javascript" charset="utf-8">
			$(document).ready(function() {
				$('#datatables').dataTable();
			} );
		</script>

Adding simply id="datatables" in my <table> does not work because it just detect one entry (Showing 1 to 1 of 1 entries) and therefore can't sort nor paginate.

2) I looked for the server side feature. I was at first not able to make it work because i did not know where i could link my $_POST variables with the $sWhere in server_processing.php
So i looked for a step by step tutorial which led me to : http://www.packtpub.com/article/data-tables-datatables-plugin-jquery-1.3-with-php
It worked pretty well but only work to display a complete database...it can't be mixed with $_POST variables that i set.

I am pretty sure that this is possible but i can't find any source (examples) to understand how this work nor tutorials for my problem.

Thank you very mych for any help you could provide me !
