个人实例dede:channelartlist 下循环出 channel 栏目中的文章

{dede:sql sql='select * from dede_arctype where reid =~id~ limit 6'}

[field:id runphp=yes]

global $dsql;

$id = @me;

$sql='select * from dede_archives where typeid='.$id;

$row=$dsql->getone($sql);

$description = cn_substr($row[description],120);

$url = GetOneArchive($row[id]);

$url = $url['arcurl'];

@me =<<<str

<h3><a target="_blank" href="$url" title="$row[title]">$row[title]</a></h3>

<p>$description</p>

</dt>

str;

[/field:id]

<dd>

[field:id runphp=yes]

global $dsql;

$id = @me;

$sql='select * from dede_archives where typeid='.$id.' limit 6';

$dsql->SetQuery($sql);//将SQL查询语句格式化

$dsql->Execute();//执行SQL操作

//通过循环输出执行查询中的结果

while($row = $dsql->GetArray()){

$url = GetOneArchive($row[id]);

$url = $url['arcurl'];

$str .=<<<str

<p><a target="_blank" href="$url" title="$row[title]" class="red"></a><a target="_blank" href="$url" title="$row[title]">$row[title]</a></p>

str;

@me = $str;

}

[/field:id]

dedecms的数据库操作类，非常实用，在二次开发中尤其重要，这个数据库操作类说明算是奉献给大家的小礼物了。

引入common.inc.php文件

require_once (dirname(__FILE__) . "/include/common.inc.php");

获取一条记录的内容

$row = $dsql->GetOne("Select * From dede_* where id = $aid");

echo $row['id'];

将查询获取总数输出

$row = $dsql->GetOne("select count(*) as dd where typeid = $typeid");

echo $row['dd'];//输出总数

将查询的若干条记录输出

$sql = "Select * from dede_*";

$dsql->SetQuery($sql);//将SQL查询语句格式化

$dsql->Execute();//执行SQL操作

//通过循环输出执行查询中的结果

while($row = $dsql->GetArray()){

echo $row['id'];

echo $row['title'];

}

//或者采取这种方式输出内容

while($row = $dsql->GetObject()){

echo $row->id;

echo $row->Title;

}

将查询的若干条记录输出dedecms5

$dsql->SetQuery("Select id,typename From `i_arctype` where reid=0 And channeltype=1 And ishidden=0 And ispart<>2 order by sortrank");

$dsql->Execute();

while($row=$dsql->GetObject())

{

$channellist .= "<a href='wap.php?action=list&id={$row->id}'>{$row->typename}</a> ";

echo $row->id;

}

插入一条记录

$sql = "

INSERT INTO `dede_member_flink`(mid,title,url,linktype,imgurl,imgwidth,imgheight)

VALUES(".$cfg_ml->M_ID.",'$title','$url','$linktype','$imgurl','$imgwidth','$imgheight');";//插入记录数据库

$dsql->ExecuteNoneQuery($sql);//执行SQL操作

$gid = $dsql->GetLastID();//获取刚刚插入的id

删除一条记录

$sql = "Delete From dede_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';";

$dsql->SetQuery($sql);

$dsql->ExecNoneQuery();

//或者使用简化模式

$dsql->ExecNoneQuery("Delete From dede_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';");

更新一条记录

$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);

判断获取数据库内容的常用方法

$row = $dsql->GetOne("Select * From dede_moneycard_type where tid={$pid}");

if(!is_array($row)){

echo "失败";

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 "失败";

}

获取总数

$dsql = new DedeSql(false);

$dsql->SetQuery("Select * from `dede_admin` where userid='$userid' Or uname='$uname'");

$dsql->Execute();

$ns = $dsql->GetTotalRow();

关闭数据库

$dsql->Close();
