I just downloaded DataTables last night and I am pretty excited to see it work, but I can't seem to get my head around some things.
I have my data in mysql DB, I have set up the server_processing.php correctly, and have set the correct path. When I run my page (pagin.php) , the screen displays (a short sample)
{"sEcho":0,"iTotalRecords":"2177","iTotalDisplayRecords":"2177","aaData":[["1500000001","Jonathan","D.","Davis","U. S. Marine","34","2\/22\/2013","Kayenta","Arizona"]]}
In server_processing.php, when I comment out 'echo json_encode( $output );' and add in it's place 'echo $aRow['fname'];', the screen will display the fname column, however when trying to populate the HTML table, I am unable to get the data to display.
This is the code I have for my pagin.php
This is the server_processing script
Can someone point me in the right direction?
Thank you
Gary
