$mysql=new mysqli('', '', '', '');
include('chk_session.php');
if($_POST['run']=='Save Insert'){

	$qr='insert into tb_news '.
	' set news_topic=\''. $mysql->real_escape_string($_POST['i_topic']).'\' '.
	', news_detail=\''.$mysql->real_escape_string($detail).'\' '.
	', news_date=\''.$mysql->real_escape_string($_POST['i_date']).'\' ';
