复制代码 代码如下:

<?php

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;

}

?>
