Question

我试图通过为我的单独类别提供一些带有子级链接的选项卡来使我的大目录在某种程度上更加平板电脑。因此，如果用户点击（第一级）头类别，则需要显示包含每个直接子项的图片，描述和URL的nr个块以及所示的所有基础（第3级）子类别的列表（第2个）级别）。你们中的任何人都会如此友好地检查我的代码吗？

<?php
   $layer = Mage::getSingleton('catalog/layer');

   $_categories = $_category->getCollection()

->addAttributeToSelect(array('url_key','name','image','all_children','is_anchor','description'))
     ->addAttributeToFilter('is_active', 1)
     ->addIdFilter($_category->getChildren())
     ->setOrder('position', 'ASC')
     ->joinUrlRewrite();

Answer 1

您可以通过以下代码进行操作，并参考底部的链接

你可以选择这个

<?php $_helper = Mage::helper('catalog/category') ?>
<?php $_categories = $_helper->getStoreCategories() ?>
<?php $currentCategory = Mage::registry('current_category') ?>
<?php if (count($_categories) > 0): ?>
    <ul class="category">
        <?php foreach($_categories as $_category): ?>
            <li>
                <a href="<?php echo $_helper->getCategoryUrl($_category) ?>">
                    <?php echo $_category->getName() ?>
                </a>
                <?php if ($currentCategory->getId() && $currentCategory->getId() == $_category->getId()): ?>
                    <?php $_category = Mage::getModel('catalog/category')->load($_category->getId()) ?>
                    <?php $_subcategories = $_category->getChildrenCategories() ?>
                    <?php if (count($_subcategories) > 0): ?>
                        <ul class="subcategory">
                            <?php foreach($_subcategories as $_subcategory): ?>
                                <li>
                                    <a href="<?php echo $_helper->getCategoryUrl($_subcategory) ?>">
                                        <?php echo $_subcategory->getName() ?>
                                    </a>
                                </li>
                            <?php endforeach; ?>
                        </ul>
                    <?php endif; ?>
                <?php endif; ?>
            </li>
        <?php endforeach; ?>
    </ul>
<?php endif; ?>

修改

<ul class="subcategory"> <? foreach ($_categories as $_category):?> <? if($_category->getIsActive()): $cur_subcategory=Mage::getModel('catalog/category')->load($_category->getId()); $layer = Mage::getSingleton('catalog/layer'); $layer->setCurrentCategory($cur_subcategory); ?> <li><a href="<?php echo $this->getCategoryUrl($_category)?>"> <?php echo $_category->getName()?></a></li> <? endif;?> <?endforeach?> </ul>

或者你可以抛出this Detail documentation，我相信这对你真的很有帮助。

Answer 2

// get current category
$current_category   = $layer->getCurrentCategory(); 

// get sub categories of current category
$parent_categories = Mage::getModel('catalog/category')->getCategories($current_category->getId());

// go through each sub category and get their sub categories.
foreach($parent_categories as $child_category)
{
     $child_category_id = $child_category->getId();
     $grandchild_categories = Mage::getModel('catalog/category')->getCategories($child_category_id);

}

这是用于显示子类别的经过测试的代码。只需将此代码放在自定义主题“ Magento_catalog / templet / product / list.phtml”中的“工具栏”代码上方

<?php
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$category = $objectManager->get('Magento\Framework\Registry')->registry('current_category');//get current category
$subcats = $category->getChildrenCategories();
$_helper = $this->helper('Magento\Catalog\Helper\Output');
$imageHelper = \Magento\Framework\App\ObjectManager::getInstance()->get(\Magento\Catalog\Helper\Image::class);


if(count ($subcats) > 0)
{
?>
<div class = "sub-cat-div">
    <ul class = "sub-cat-main">
        <?php
        foreach ($subcats as $subcat) {
            if ($subcat->getIsActive()) {
                $_category = $objectManager->create('Magento\Catalog\Model\Category')->load($subcat->getId());
                $_outputhelper = $this->helper('Magento\Catalog\Helper\Output');
                $subcaturl = $_category->getUrl();

                $_imgHtml = '';
                if ($_imgUrl = $_category->getImageUrl()) {

                    $_imgHtml = '<img src="' . $_imgUrl . '" />';
                    $_imgHtml = $_outputhelper->categoryAttribute($_category, $_imgHtml, 'image');


                    echo '<li class="sub-cat-image"><a href="' . $subcaturl . '" class="block-promo" title="' . $_category->getName() . '">' . $_imgHtml . '<span style="background-color: rgba(255,255,255,0.9)" class="content bg-white"><strong>' . $_category->getName() . '</strong></span></a></li>';
                }
                else{
                    $_imgUrl = $imageHelper->getDefaultPlaceholderUrl('image');
                    $_imgHtml = '<img src="' . $_imgUrl . '" />';
                    $_imgHtml = $_outputhelper->categoryAttribute($_category, $_imgHtml, 'image');


                    echo '<li class="sub-cat-image"><a href="' . $subcaturl . '" class="block-promo" title="' . $_category->getName() . '">' . $_imgHtml . '<span style="background-color: rgba(255,255,255,0.9)" class="content bg-white"><strong>' . $_category->getName() . '</strong></span></a></li>';
                }
            }
        } ?>
    </ul>
</div>
<?php 
}
?>
