織夢DedeCMS允許不同會員發布相同文章，不允許同一會員發布重復文章的方法：
打開 /member/inc/archives_check.php 文件
找到
//檢測文檔是否重復
if($cfg_mb_cktitle=='Y')
{
$row = $dsql->GetOne("Select * From `dede_archives` where title like '$title' ");
if(is_array($row))
{
ShowMsg("對不起，請不要發布重復文檔！","-1","0",5000);
exit();
}
}
將
$row = $dsql->GetOne("Select * From `dede_archives` where title like '$title' ");
修改為
$row = $dsql->GetOne("Select * From `dede_archives` where title like '$title' and mid = '".$cfg_ml->M_ID."'");
