织梦dedecms设置根据文章标题自动获取tag的方法

修改：\dede\action目录article_add_action.php文件 

在【//写入Tag索引】与【InsertTags($dsql,$tag,$arcID,0,$typeid,$arcrank);】之间插入： 

if($autokey==1){

    require_once(DEDEADMIN."/../include/pub_splitword_[url]www.php[/url]");

    $tag = "";

    $sp = new SplitWord();

    $titleindexs = explode(" ",trim($sp->GetIndexText($sp->SplitRMM($title))));

    //$allindexs = explode(" ",trim($sp->GetIndexText($sp->SplitRMM(Html2Text($body)),200)));

    if(/*is_array($allindexs) && */is_array($titleindexs)){

        foreach($titleindexs as $k){   

            if(strlen($tag)>=50) break;

            else $tag .= $k." ";

        }

        /*foreach($allindexs as $k){

            if(strlen($keywords)>=50) break;

            else if(!in_array($k,$titleindexs)) $keywords .= $k." ";

     }*/

    }

    $sp->Clear();

    unset($sp);

    //$tag = preg_replace("/#1#|#2#/","",$tag);

    $tag = addslashes($tag);

}
