復制代碼 代碼如下:

<?php
private function _deleteSubNode($ids){

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

?>
