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."'");
