Question

我需要使用导航菜单渲染侧边栏，导航菜单包含应用程序的所有类别及其各自的子类别。但是，当当前页面指的是类别或子类别时，当前类别需要是菜单中的第一个，但我不知道如何正确执行此操作。

我想到的第一件事就是重复循环两次，在第一个循环中检查所讨论的类别是否与当前请求的类别相同，然后渲染它，否则跳过循环。另一个循环几乎是相同的，但如果类别与当前请求的类别相同，则跳过循环到下一个元素。但这是一个非常糟糕的主意，重复两次HTML，使维护变得头痛。

我目前的代码：

//View Helper
<?php
namespace App\View\Helper;

class Category extends AbstractHelper {

    protected $category;

    /**
     * @param \Entities\Product\Category $category
     * @return \App\View\Helper\Category
     */
    public function category( \Entities\Product\Category $category = null )
    {
        $this->category = $category;
        return $this;
    }

    /**
     * @return string
     */
    public function renderSidebar( )
    {
        $repositoryHelper = \Zend_Controller_Action_HelperBroker::getStaticHelper( 'repository' );
        $categories = $repositoryHelper->getRepository( 'Product\Category' )->getCategoriesWithSubCategories();

        $isCorrectAction = ($this->getRequestVariable( 'action', false ) === 'products');
        $isACategoryPage = false;
        $requestedCategoryId = $this->getRequestVariable( 'category', false );

        if( $isCorrectAction && $requestedCategoryId ){
            $isACategoryPage = true;
        }

        return $this->view->partial(
            'partials/categoriesSidebar.phtml',
            array(
                'categories'      => $categories,
                'isACategoryPage' => $isACategoryPage,
                'requestedCategoryId' => (int) $requestedCategoryId
            )
        );
    }


}

//inside categoriesSidebar.phtml
<ul class="sidebar-menu">
    <?php foreach( $this->categories as $category ): ?>
        <?php if( $this->isACategoryPage && $this->requestedCategoryId === $category->getId()): ?>
            //???
        <?php endif; ?>
        <li class="category" id="category-<?= $category->getId() ?>">
            <a href="..." class="category-link"><?= $category->getName() ?></a>
            <?php if( $category->hasSubCategories() ): ?>
                <span class="subcategory-view desactivated"></span>
                <ul class="category-subcategories">
                    <?php foreach( $category->getSubCategories() as $subCategory ): ?>
                        <li class="subcategory category-<?= $category->getId() ?>-subcategories" id="subcategory-<?= $subCategory->getId() ?>" data-category="<?= $category->getId() ?>">
                            <a href="..." class="subcategory-link"><?= $subCategory->getName() ?></a>
                        </li>
                    <?php endforeach; ?>
                </ul>
            <?php endif; ?>
        </li>
    <?php endforeach; ?>
</ul>

您对我如何做到这一点有什么想法吗？我没有使用Zend_Navigation，在这种情况下，我应该使用它？或者我应该用CSS做这个吗？
