织梦采集跳过相同标题文章采集

织梦采集到相同文章时，织梦会重复添加文章，我们要让相同的文章跳过采集

打开 /dede/article_add.php 找到

if(empty($click)) $click = ($cfg_arc_click=='-1' ? mt_rand(50, 200) : $cfg_arc_click);

在它的下面加入

if(!empty($title) && $cfg_check_title=='Y'){$row = $dsql->GetOne("SELECT id FROM `dede_archives` WHERE title LIKE '$title' ");if(is_array($row)){if(empty($typeid)){ShowMsg("请指定文档的栏目！","-1");exit();}if(empty($channelid)){ShowMsg("文档为非指定的类型，请检查你发布内容的表单是否合法！","-1");exit();}if(!CheckChannel($typeid,$channelid)){ShowMsg("你所选择的栏目与当前模型不相符，请选择白色的选项！","-1");exit();}if(!TestPurview('a_New')){CheckCatalog($typeid,"对不起，你没有操作栏目 {$typeid} 的权限！");}//对保存的内容进行处理$id = $row['id'];$pubdate = GetMkTime($pubdate);$sortrank = AddDay($pubdate,$sortup);$ismake = $ishtml==0 ? -1 : 0;$autokey = 1;$title = dede_htmlspecialchars(cn_substrR($title,$cfg_title_maxlen));$shorttitle = $shorttitle;$color =  cn_substrR($color,7);$writer =  $writer;$source = $source;$description = cn_substrR($description,250);$keywords = trim(cn_substrR($keywords,60));$filename = trim(cn_substrR($filename,40));$isremote  = (empty($isremote)? 0  : $isremote);$serviterm=empty($serviterm)?
