// DB table to use
$table = 'datatables_demo';

// Table's primary key
$primaryKey = 'id';

// Array of database columns which should be read and sent back to DataTables.
// The db parameter represents the column name in the database, while the dt
// parameter represents the DataTables column identifier - in this case object
// parameter names
$columns = array(
array(
'db' => 'id',
'dt' => 'DT_RowId',
'formatter' => function( $d, $row ) {
// Technically a DOM id cannot start with an integer, so we prefix
// a string. This can also be useful if you have multiple tables
// to ensure that the id is unique with a different prefix
return 'row_'.$d;
}
),
array( 'db' => 'first_name', 'dt' => 'first_name' ),
array( 'db' => 'last_name', 'dt' => 'last_name' ),
array( 'db' => 'position', 'dt' => 'position' ),
array( 'db' => 'office', 'dt' => 'office' ),
array( 'db'='sites.name' 'dt'=>'sites.name)
)
->leftJoin( 'sites', 'sites.last_name', '=', 'users.name' )
->leftJoin(
);

$sql_details = array(
'user' => '',
'pass' => '',
'db' => '',
'host' => ''
);
