我需要呈现一个带有导航菜单的侧边栏,其中包含应用程序的所有类别及其各自的子类别。但是,当当前页面引用一个类别或子类别时,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。
我首先想到的是重复循环两次,在第一次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。另一个循环几乎是一样的,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。但这是个很糟糕的主意,重复 HTML 两次,让维护很头疼。
我当前的代码:
//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想法吗?我没有使用 Zend_Navigation,在这种情况下,我应该使用它吗?还是我应该只用 CSS 做这个?
