代码如下:
private function _deleteSubNode($ids){

$subNodes = array();
$mod = D('Node');
foreach (explode ( ',', $ids ) as $k){
$res = $this->_getSubNode($k,$subNodes[$k],$mod); //获取子节点
if(!empty($res[0])){
foreach($res as $k => $nid){
$mod->where('id = '.$nid)->delete(); //删除子节点
}
}
}
return ;
}

private function _getSubNode($id, &$arr,$mod){

$condition = array ('pid' => array ('eq', $id ));
$ret = $mod->where($condition)->getField('id');
if(!empty($ret[0])){
foreach ($ret as $k => $node){
$arr[] = $node['id'];
$this->_getSubNode($node['id'], $arr, $mod);
}
}
return $arr;
}

?>
