dedecms操作數(shù)據(jù)庫(kù)的各類(lèi)方法，二次開(kāi)發(fā)都會(huì)用到的。
首先，引入common.inc.php文件
require_once (dirname(__file__) . \”/include/common.inc.php\”);
1、獲取一條記錄的內(nèi)容：
$row = $dsql->getone(\”select * from dede_* where id = $aid\”); echo $row[\’id\’];
2、將查詢(xún)獲取總數(shù)輸出：
$row = $dsql->getone(\”select count(*) as dd where typeid = $typeid\”); echo $row[\’dd\’];//輸出總數(shù)
3、將查詢(xún)的若干條記錄輸出
$sql = \”select * from dede_*\”; $dsql->setquery($sql);//將sql查詢(xún)語(yǔ)句格式化 $dsql->execute();//執(zhí)行sql操作 //通過(guò)循環(huán)輸出執(zhí)行查詢(xún)中的結(jié)果 while($row = $dsql->getarray()){ echo $row[\’id\’]; echo $row[\’title\’]; } //或者采取這種方式輸出內(nèi)容 while($row = $dsql->getobject()){ echo $row->id; echo $row->title; }
4、將查詢(xún)的若干條記錄輸出
$dsql->setquery(\”select id,typename from `dede_arctype` where reid=0 and channeltype=1 and ishidden=0 and ispart<>2 order by sortrank\”); $dsql->execute(); while($row=$dsql->getobject()) { $channellist .= \”{$row->typename} \”; echo $row->id; }
5、插入一條記錄
$sql = \” insert into `dede_member_flink`(mid,title,url,linktype,imgurl,imgwidth,imgheight) values(\”.$cfg_ml->m_id.\”,\’$title\’,\’$url\’,\’$linktype\’,\’$imgurl\’,\’$imgwidth\’,\’$imgheight\’);\”;//插入記錄數(shù)據(jù)庫(kù) $dsql->executenonequery($sql);//執(zhí)行sql操作 $gid = $dsql->getlastid();//獲取剛剛插入的id
6、刪除一條記錄
$sql = \”delete from dede_member_flink where aid=\’$aid\’ and mid=\’\”.$cfg_ml->m_id.\”\’;\”; $dsql->setquery($sql); $dsql->execnonequery(); //或者使用簡(jiǎn)化模式 $dsql->execnonequery(\”delete from dede_member_flink where aid=\’$aid\’ and mid=\’\”.$cfg_ml->m_id.\”\’;\”);
7、更新一條記錄
$upquery = \” update dede_member_flink set title=\’$title\’,url=\’$url\’,linktype=\’$linktype\’, imgurl=\’$imgurl\’,imgwidth=\’$imgwidth\’,imgheight=\’$imgheight\’ where aid=\’$aid\’ and mid=\’\”.$cfg_ml->m_id.\”\’; \”; $rs = $dsql->executenonequery($upquery);
8、判斷獲取數(shù)據(jù)庫(kù)內(nèi)容的常用方法
$row = $dsql->getone(\”select * from dede_moneycard_type where tid={$pid}\”); if(!is_array($row)){ echo \”失敗\”; exit(); } $upquery = \” update dede_member_flink set title=\’$title\’,url=\’$url\’,linktype=\’$linktype\’, imgurl=\’$imgurl\’,imgwidth=\’$imgwidth\’,imgheight=\’$imgheight\’ where aid=\’$aid\’ and mid=\’\”.$cfg_ml->m_id.\”\’; \”; $rs = $dsql->executenonequery($upquery); if($rs){ echo \”成功\”; }else{ echo \”失敗\”; }
9、獲取總數(shù)
$dsql = new dedesql(false); $dsql->setquery(\”select * from `dede_admin` where userid=\’$userid\’ or uname=\’$uname\’\”); $dsql->execute(); $ns = $dsql->gettotalrow(); 關(guān)閉數(shù)據(jù)庫(kù) $dsql->close();
