require_once("checkpostandget.php");
require_once("global.php");
//$ID=intval($_GET['id']);
$iD = intval(base64_decode($_GET['iD']));
$query="select * from chengyu where ID =".$ID."";
$result=mysql_query($query);

while ($rs = mysql_fetch_object($result)){ 
?>

while ($rs = mysql_fetch_object($result)){ //第9行

------解决方案--------------------
ID、iD、id。。先把变量名称的大小写都写对了再说。
------解决方案--------------------
$query="select * from chengyu where ID =".$ID.""; 中
$ID 没有值
------解决方案--------------------
很明显是mysql_query没有值,mysql_query没有值,有可能是$query语句有错误。$query没有错误,说明$ID不正确。
