Where clause not working in data table server-side processing

问题

I am using data table Server-side processing. I am getting the data from the database. My issue is, Where clause not working with Server-side processing. I am using the below code. I found one link on Stack overflow and I added the same code but that code is also not working.

I refer this link

How to use 'WHERE' clause using ssp.class.php DataTables

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


if($_REQUEST['action']=='admin'){

$table = 'tbl_admin';
$primaryKey = 'admin_id';
$columns = array(
    array( 'db' => 'firstname', 'dt' => 0 ),
    array( 'db' => 'lastname',  'dt' => 1 ),
    array( 'db' => 'email',   'dt' => 2 ),
    array( 'db' => 'date_of_created','dt' => 3,
        'formatter' => function( $d, $row ) {
            return date( 'd-m-Y', strtotime($d));
        }
    )
);
require 'datatables/ssp.class.php';
//$where = "is_active =1 order by DESC date_of_created"; //tried this
 //$where = "is_active ='1'"; //tried this
 $where = "is_active =1"; // tried this
 
echo json_encode(
    SSP::simple( $_GET, $sql_details, $table, $primaryKey, $columns, null, $where )
);

}

Would help in out in this solution?
