php实现保存submit内容之后禁止刷新

$strsql = "INSERT INTO `xxx` (`aaa`) VALUES ('".$_POST["bbb"]."','".$_POST["ccc"]."',,now())";

$result=@mysql_query($strsql,$my_con);
$maxrow=@mysql_affected_rows();
Testecho ($y.mysql_affected_rows()." $errcode ".$strsql); #debug
mysql_sql_log($strsql,mysql_affected_rows(),$_SERVER['SCRIPT_NAME'].":".__LINE__);
if($maxrow>0){
$insertflag =1;
}

echo '<script>location.href="6612.php?inserted=1"</script>';

<?php echo $insertflag;print_r($_GET); if($_GET[inserted]!=1){?>
<input type="submit" value="新規登録" name="insertN" class="box1a"></input>
<?php }else{?>
