function tags($field, $value)
    {
        if(!$value) return '';
        if(strpos($value, ','))
        {
            $s = ',';
        }
        else
        {
            $s = ',';
        }

        $keywords = isset($s) ? array_unique(array_filter(explode($s, $value))) : array($value);
        $keyword_db = pc_base::load_model('keyword_ext_model');

        foreach($keywords as $tag)
        {
            $tag = trim($tag);
            $keyword_db->delete(array("tag"=>$tag,"modelid"=>$this->modelid));
            $c=$this->db->count("keywords like '%".$tag."%'");
            $keyword_db->insert(array("modelid"=>$this->modelid,"tag"=>$tag,"usetimes"=>$c,"lastusetime"=>SYS_TIME),false,true);
        }

        return implode($s, $keywords);
}
