-->mysql_select_db($db_name,$connection)or die("选择数据库失败");
$query="delect from hotel_activities_2 where " ;//主要是这怎么写
if (mysql_query($query)){
    echo "删除数据成功";
}else{
echo "删除失败";    
}
mysql_close($connection);

大侠们帮帮忙

------解决方案--------------------
$query="delete from hotel_activities_2 where h_id={$_GET['hid']} " ;
------解决方案--------------------
$hid = !empty($_GET['hid']) ? intval($_GET['hid']) : 0;

加上对$hid的判断

where 字段 = $hid;
