打開plus下diy.php文件
找到

    if(!is_array($diyform))             {                 showmsg('自定義表單不存在', '-1');                 exit();             }

再其下添加

    //檢測游客是否已經提交過表單 if(isset($_COOKIE['VOTE_MEMBER_IP'])) { if($_COOKIE['VOTE_MEMBER_IP'] == $_SERVER['REMOTE_ADDR']) { ShowMsg('您已經填寫過表單啦','-1'); exit(); } else {  setcookie('VOTE_MEMBER_IP',$_SERVER['REMOTE_ADDR'],time()*$row['spec']*3600,'/');      } } else {  setcookie('VOTE_MEMBER_IP',$_SERVER['REMOTE_ADDR'],time()*$row['spec']*3600,'/');        }

替換后即可實現織夢自定義表單限制IP發表次數
