视图
cdnauto/views/config/indexphp 复制代码 代码如下:
echo CHtml::dropDownList(node CHtml::listData(Node::model()>findAll()namename)array(empty=>请选择节点
id => node
ajax=>array(
type=>POST
url=>Yii::app()>createUrl(cdnauto/config/getNodeServersByNodeName)
update=>#servers
data=>array(node_name=>js:$("#node")val())
)
)
);
echo " ";
echo CHtml::dropDownList(servers array(请选择服务器));
控制器
cdnauto/controllers/ConfigControllerphp
复制代码 代码如下:
public function actionGetNodeServersByNodeName(){
// if(!Yii::app()>request>isAjaxRequest)
// throw new CHttpException();
$node_name = $_POST[node_name];
$nodeid = Node::model()>getNodeId($_POST[node_name]); //通过节点名称获取该节点ID
$server = GossServer::model()>getServerByNodeid($nodeid); //通过节点ID获取服务器信息
//$server 为array类型形如 $server = array(array(name=>name)array(name=>name));所以需要两次foreach
if(isset($server)){
foreach ($server as $k=>$v){
foreach($v as $kk => $vv){
echo CHtml::tag(option array(value=>$kk) CHtml::encode($vv) true);
}
}
}else{
echo CHtml::tag(option array(value=>) servers true);
}
}
模型
GossServerphp
复制代码 代码如下:
/**
* 通过节点ID获取该节点下所有的服务器名称
* @author ysdaniel
*/
public static function getServerByNodeid($nodeid)
{
$sql = "SELECT name FROM OSS_Server WHERE nodeid = {$nodeid} ";
///$sql = "SELECT namenodeid FROM OSS_Server WHERE nodeid = {$nodeid} "; //both ok
$cmd = Yii::app()>db>createCommand($sql);
$ret = $cmd>queryAll();
if (!$ret){
throw new Exception("找不到这个节点对应的服务器");
}
return $ret;
}
Nodephp
复制代码 代码如下:
/**
* 通过nodename获取nodeid名
* @author
*/
public static function getNodeId($name)
{
$sql = "SELECT id FROM OSS_Node WHERE name = {$name}";
$cmd = Yii::app()>db>createCommand($sql);
$ret = $cmd>queryAll();
if (!$ret){
return null;
//throw new Exception("找不到Node{$name}");
}
return $ret[][id];
}
其它
数据表结构
效果
没有选择节点前
细节有空再补上了
