带knpmenubundle的嵌套动态菜单

Question

我使用knpmenubundle构建了一个菜单，它工作得很好并且从数据库中动态地拉动导航。但是，客户端现在想要为其添加子菜单。我已经编写了一个可以找到子页面的控制器，但是我无法看到如何将它们附加到正确父级下的子导航中。所有这一切都将当前元素的副本作为子节点附加到自身。

以下是菜单构建器：

 $sector = $options['sector'];
    $em = $this->getDoctrine()->getManager();
    $navItems = $this->getDoctrine()
    ->getRepository('acmeStyleGuideBundle:pageSector')
    ->findBySectorJoinedToUrl($sector);
    if (!$navItems) throw $this->createNotFoundException('Unable to find any matching pages');
    $menu = $factory->createItem('root');
    foreach ($navItems as $nav)
    {
        // Doesn't have any parents, This is a top level
        $parent = $menu->addChild($nav->getPageName(), array(
            'route' => 'acme_style_guide_pages_show',
            'routeParameters' => array(
                'sector' => $sector,
                'pageUrl' => $nav->getPageUrl()
            )
        ));
        $parent->addChild($nav->getPageName(), array(
            'route' => 'acme_style_guide_pages_show_sub',
            'routeParameters' => array(
                'sector' => $sector,
                'pageParent' => $nav->getPageName(),
                'pageUrl' => $nav->getPageUrl()
            ))
        );
    }

以下是父元素的控制器：

 // Render pages from database
public function showAction($sector, $pageUrl)
{
    $em = $this->getDoctrine()->getManager();
    $pages = $this->getDoctrine()
    ->getRepository('acmeStyleGuideBundle:PageContent')
    ->findByUrlJoinedToSector($sector, $pageUrl);

    if (!$pages) throw $this->createNotFoundException('Unable to find any matching pages');
    return $this->render(
        'acmeStyleGuideBundle:Page:pages.html.twig', 
        array(
            'Pages' => $pages,
            'sector' => $sector
        )
    );
}

，这里是子元素的控制器：

// Render sub pages from database
public function showSubAction($sector, $pageParent, $pageUrl)
{
    $em = $this->getDoctrine()->getManager();
    $pages = $this->getDoctrine()
    ->getRepository('acmeStyleGuideBundle:PageContent')
    ->findByUrlJoinedToSectorAndParent($sector, $pageParent, $pageUrl);

    if (!$pages) throw $this->createNotFoundException('Unable to find any matching pages');
    return $this->render(
        'acmeStyleGuideBundle:Page:pages.html.twig', 
        array(
            'Pages' => $pages,
            'sector' => $sector
        )
    );
}

这两个控制器都使用自定义存储库类从数据库中提取信息。

以下是自定义存储库代码：

public function findByUrlJoinedToSector($sector, $pageUrl)
{
    $query = $this->getEntityManager()
        ->createQuery('
            SELECT p, s FROM acmeStyleGuideBundle:PageContent p
            JOIN p.pageSector s
            LEFT JOIN p.pageTypes t
            WHERE p.pageUrl = :url
            AND s.sectorName = :sector
            AND t.typeName != :type'
        )
        ->setParameter('url', $pageUrl)
        ->setParameter('sector', $sector)
        ->setParameter('type', 'Section Headers');

    try {
        return $query->getResult();
    } catch (\Doctrine\ORM\NoResultException $e) {
        return null;
    }
}

public function findByUrlJoinedToSectorAndParent($sector, $pageParent, $pageUrl)
{
    $query = $this->getEntityManager()
        ->createQuery('
            SELECT p, s, c FROM acmeStyleGuideBundle:PageContent p
            JOIN p.pageSector s
            LEFT JOIN p.pageTypes t
            LEFT JOIN p.PageParent c
            WHERE p.pageUrl = :url
            AND s.sectorName = :sector
            AND c.pageUrl = :parent
            AND t.typeName != :type'
        )
        ->setParameter('url', $pageUrl)
        ->setParameter('sector', $sector)
        ->setParameter('parent', $pageParent)
        ->setParameter('type', 'Section Headers');

    try {
        return $query->getResult();
    } catch (\Doctrine\ORM\NoResultException $e) {
        return null;
    }
}

这可能只是一个<星期一早上问题，所以我会继续尝试自己解决，如果我这样做，我会在这里发布它作为答案。

其他信息

更新的构建器   //找到父母的所有项目。然后将找到的项目附加到其父项。             $ subNavItems = $ this-＆gt; getDoctrine（）              - ＆GT; getRepository（ 'acmeStyleGuideBundle：pageSector'）              - ＆gt; findSubNav（$ sector，$ nav-＆gt; getPageParent（））;

        // loop over them and add a link for each one:
        foreach ($subNavItems as $child) {
            if ($child->getPageParent() != NULL) {
                $parent->addChild($child->getPageName(), array(
                    'route' => 'acme_style_guide_pages_show_sub',
                    'routeParameters' => array(
                        'sector' => $sector,
                        'pageParent' => $child->getPageName(),
                        'pageUrl' => $child->getPageUrl()
                        )
                    )
                );
            }
        }
    }

正在输出：

<ul>
    <li><a href="link">Target Item</a></li>
    <li><a href="link">Item</a></li>
    <li><a href="link">Item</a></li>
    <li><a href="link">Child</a>
        <ul>
            <li><a href="link">Child</a></li>
        </ul>
    </li>
</ul>

我需要输出：

<ul>
    <li><a href="link">Target Item</a>
        <ul>
            <li><a href="link">Child</a></li>
        </ul>
    </li>
    <li><a href="link">Item</a></li>
    <li><a href="link">Item</a></li>
    <li><a href="link">Child</a></li>
</ul>

这是PageContent表的架构

Answer 1

您需要遍历所有subElements并为每个{：p>呈现导航链接

foreach ($navItems as $nav)
{
    // Doesn't have any parents, This is a top level
    $parent = $menu->addChild($nav->getPageName(), array(
        'route' => 'acme_style_guide_pages_show',
        'routeParameters' => array(
            'sector' => $sector,
            'pageUrl' => $nav->getPageUrl()
        )
    ));

    // find all sub-items:
    $subNavItems = $this->getDoctrine()
    ->getRepository('acmeStyleGuideBundle:pageSector')
    ->findByUrlJoinedToSectorAndParent($sector, $parent, /* $pageUrl */);

    // loop over them and add a link for each one:
    foreach ($subNavItems as $child) {
        $parent->addChild($child->getPageName(), array(
            'route' => 'acme_style_guide_pages_show_sub',
            'routeParameters' => array(
                'sector' => $sector,
                'pageParent' => $child->getPageName(),
                'pageUrl' => $child->getPageUrl()
            ))
        );
    }
}
