datatable.net tablosunu kullanmaya çalışıyorum. ServerSide açıklamalarını okudum fakat şu anda hiç bir hata vermiyor ve verileri getirmiyor.

<script type="text/javascript" class="init">
$(document).ready(function() {
    $('#makina').DataTable( {
        "serverSide": true,
        "ajax": "server_porcessing.php"
		    } );
} );
	</script>


<form><table id="makina" class="display" cellspacing="0" width="100%">
        <thead>
            <tr>
                <th>id</th>
                <th>Makina Kodu</th>
                <th>Makina Tanım</th>
                <th>Tonaj</th>
                <th>Marka</th>
                <th>Model</th>
                <th>Yıl</th>
                <th>Vida Tipi</th>
				<th>Açıklama</th>
            </tr>
        </thead>
 
        <tfoot>
            <tr>

                <th>id</th>
                <th>Makina Kodu</th>
                <th>Makina Tanım</th>
                <th>Tonaj</th>
                <th>Marka</th>
                <th>Model</th>
