我正在使用：
要设置树结构，我在Symfony.com [2]上使用了文档，后面是关于GitHub [3]的文档。然后我继续进行树设置 - 使用示例[4]中的树实体，并使用[5]中的代码创建树。
我确实设置了名为FileTree的树结构（代表目录和文件）。我在树中添加了几个自定义字段：item_name，item_extension和is_file。已移除title，因为我有item_name ...
我的FileTree实体：

我需要按文件类型在树的文件夹中订购文件 - 即：item_extension然后按item_name。目前Gedmo Nestedset Tree按root和lft排序，如下一个代码块所示。
public function getFileTreeNodeArray($file_tree_root_id)
{
$em = $this->getEntityManager();
$query = $em
->createQueryBuilder()
->select('ft')
->from('AppBundle:FileTree', 'ft')
->where('ft.root = :root')
->setParameter('root', $file_tree_root_id)
->orderBy('ft.root, ft.lft', 'ASC')
->getQuery();
$query->setHint(\Doctrine\ORM\Query::HINT_INCLUDE_META_COLUMNS, true);
$build_my_tree = $query->getArrayResult();
return $build_my_tree;
}
遗憾的是，添加额外的->orderBy('ft.item_extension', 'ASC')并未产生任何结果......
然后我了解到[6]有两个功能可以帮助我完成这项工作reorderAll和reorder。我尝试了他们两个，但遗憾的是，物品没有改变他们的订单，他们仍然按root和lft订购。
我的代码来自Upload Listener：
$repo_file_tree = $this->entityManager->getRepository('AppBundle:FileTree');
$root_node_id = $repo_file_tree->getFileTreeRootNodeIdByProjectId($selected_node_parent_id);
$root_node = $repo_file_tree->findOneBy(array('id' => $root_node_id));
$repo_file_tree->reorder($root_node, 'item_extension, item_name', 'ASC');
$this->entityManager->flush();
或
$repo_file_tree = $this->entityManager->getRepository('AppBundle:FileTree');
$repo_file_tree->reorderAll('item_extension, item_name', 'ASC');
$this->entityManager->flush();
如何获得FileTree按item_extension, item_name排序的reorder项目的数组？
我会对以太正确的Doctrine查询（最好）或解释包含函数reorderAll和* {

padding: 0px;
}

font-weight: bold;
font-size: 80%;

.topnav>.search {

display: inline-block;
}的代码块有什么问题感到满意。
我错过了什么？
请告知。
感谢您的时间和知识。
答案 0 :(得分：0)
刚刚将我的项目更新为Symfony v3.2.0
现在我收到错误
Invalid sort options specified: field - item_extension, item_name, direction - ASC
500 Internal Server Error - InvalidArgumentException
使用上述代码时使用reorder。
我不确定它是刚刚发生的（升级后）还是Symfony v3.1.x。
无论如何 - 很明显reorder只占用了一个字段来命令树分支。我之前尝试的不是多个字段。
所以答案是：在调用reorder函数时不要使用多个排序字段。
$repo_file_tree = $this->entityManager->getRepository('AppBundle:FileTree');
$root_node_id = $repo_file_tree->getFileTreeRootNodeIdByProjectId($selected_node_parent_id);
$root_node = $repo_file_tree->findOneBy(array('id' => $root_node_id));
$repo_file_tree->reorder($root_node, 'item_extension', 'ASC');
$this->entityManager->flush();
