<title>{dede:field.seotitle/}</title>
<meta name="keywords" content="{dede:field name='keywords'/}" />
<meta name="description" content="{dede:field name='description' function='html2text(@me)'/}" />php
第一步:打開/include/typelink.class.php 找到這一段代碼 $this->TypeInfos = $this->dsql->GetOne($query); 在他下面加上三行代碼加好以後以下html
//載入類目信息 $query = "SELECT tp.*,ch.typename as ctypename,ch.addtable,ch.issystem FROM `dede_arctype` tp left join `dede_channeltype` ch on ch.id=tp.channeltype WHERE tp.id='$typeid' "; if($typeid > 0) { $this->TypeInfos = $this->dsql->GetOne($query); //填空 $this->TypeInfos['keywords'] = $this->TypeInfos['keywords'] ? $this->TypeInfos['keywords'] : $this->GetTrueInfos('keywords'); $this->TypeInfos['seotitle'] = $this->TypeInfos['seotitle'] ? $this->TypeInfos['seotitle'] : $this->GetTrueInfos('seotitle'); $this->TypeInfos['description'] = $this->TypeInfos['description'] ? $this->TypeInfos['description'] : $this->GetTrueInfos('description'); if(is_array($this->TypeInfos)) { $this->TypeInfos['tempindex'] = MfTemplet($this->TypeInfos['tempindex']); $this->TypeInfos['templist'] = MfTemplet($this->TypeInfos['templist']); $this->TypeInfos['temparticle'] = MfTemplet($this->TypeInfos['temparticle']); } }
第二步:在TypeLink類中增長一個調用方法GetTrueInfos($info) 代碼以下:web
//爲了讓某些欄目的關鍵字描述等不能爲空 function GetTrueInfos($info = 'seotitle') { $infos = array('reid'=>$this->TypeID,$info=>''); while(empty($infos[$info]) && $infos['reid']!=0) { $this->dsql->SetQuery("SELECT reid,".$info." FROM dede_arctype WHERE id='".$infos['reid']."'"); $infos = $this->dsql->GetOne(); } if(empty($infos[$info])) { if($info == "seotitle") return $GLOBALS['cfg_webname']; if($info == "keywords") return $GLOBALS['cfg_keywords']; if($info == "description") return $GLOBALS['cfg_description']; } return $infos[$info]; } 保存以後,這裏咱們去生成一下預覽效果,此方法在DEDECMS 5.7 SP1上測試有效,其它版本未測試。
