symfony - knpmenubundle を使用したネストされた動的メニュー

Question

knpmenubundle を使用してメニューを作成しました。これは非常にうまく機能しており、データベースから動的にナビゲーションを取得しています。ただし、クライアントはサブメニューを追加したいと考えています。子ページを見つけるコントローラーを作成しましたが、正しい親の下のサブナビゲーションにそれらをアタッチする方法がわかりません。現時点では、現在の要素のコピーを自分自身に子ノードとしてアタッチします。

メニュービルダーは次のとおりです。

 $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()
            ))
        );
    }

親要素のコントローラーは次のとおりです。

 // 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
        )
    );
}

子要素のコントローラーは次のとおりです。

// 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
        )
    );
}

これらのコントローラはどちらも、カスタム リポジトリ クラスを使用してデータベースから情報を取得します。

カスタム リポジトリ コードは次のとおりです。

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;
    }
}

月曜日の朝の問題かもしれないので、自分で解決しようとし続けます。そうする場合は、回答としてここに投稿します。

追加情報

更新されたビルダー // 親を持つすべてのアイテムを検索します。次に、見つかったアイテムをその親にアタッチします。$subNavItems = $this->getDoctrine() ->getRepository('acmeStyleGuideBundle:pageSector') ->findSubNav($sector, $nav->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()
                        )
                    )
                );
            }
        }
    }

出力しています：

<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>

私はそれを出力する必要がありますが：

<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>

Answer 1

subElementsすべてをループして、それぞれのナビゲーション リンクをレンダリングする必要があります。

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()
            ))
        );
    }
}
