Question

简介

我正在使用：

Windows 10 Pro
XAMPP with PHP v7.0.9
Symfony v3.1.7
Doctrine v2.5.4
StofDoctrineExtensionsBundle [1]以管理树状结构。

设置

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：

问题

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();

问题

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* { margin: 0px; padding: 0px; } .top-header { width: 100%; height: 40px; background: #FFFFFF; } .top-header>img { float: left; width: 70px; height: 25px; padding-left: 10px; padding-top: 8px; padding-right: 10px; padding-left: 100px; } .signinimg { float: left; border-left: 1px solid #E4E4E4; padding-top: 8px; height: 32px; padding-left: 20px; } .signin { float: left; padding-top: 12px; font-family: Arial, Helvetica, freesans, sans-serif; font-size: 80%; padding-right: 10px; font-weight: bold; padding-right: 100px; } .topnav { float: left; list-style: none; } .topnav>.t1 { height: 40px; width: 60px; border-left: 1px solid #E4E4E4; display: inline-block; text-align: center; } .topnav>.t2 { height: 40px; width: 60px; border-left: 1px solid #E4E4E4; display: inline-block; text-align: center; border-right: 1px solid #E4E4E4; } .topnav>.t1>a { text-decoration: none; color: black; font-family: Arial, Helvetica, freesans, sans-serif; font-weight: bold; font-size: 80%; line-height: 40px; } .topnav>.t2>a { text-decoration: none; color: black; font-family: Arial, Helvetica, freesans, sans-serif; font-weight: bold; font-size: 80%; line-height: 40px; } .topnav>.search { height: 40px; display: inline-block; }的代码块有什么问题感到满意。

结论

我错过了什么？

请告知。

感谢您的时间和知识。

Answer 1

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();

使用symfony3，doctrine2和stofDoctrineExtensionsBundle
