使用 PHP 仅显示 10 个列表项？

Question

我构建了一个子类别小部件，它从父猫 ID 中提取所有子类别并将它们显示为列表项。我只想显示 10 个列表项，除此之外，显示一个链接回父猫 ID 的“查看全部”链接。我如何使用下面的前端代码完成此操作？

    foreach ($subCats as $subcat) {

        $_category = $objectManager->create('Magento\Catalog\Model\Category')->load($subcat->getId());

        $subcaturl = $subcat->getUrl();

        } ?>

                        <li class="cat-li" style="list-style-type: none;">

                            <div class="product-item-info">

                                <div class="product-item-details">

                                    <ul class="productsub-categories" style="text-align: left;">

                                       <a href="<?php echo $subcaturl; ?>">

                                            <strong ><?php echo $subcat->getName(); ?></strong>

                                        </a>

                                    </ul>

                                </div>

                            </div>

                        </li>

首先，您的 HTML 不在循环中。其次，只需增加一个计数器并检查 10 和break：$i = 0;foreach ($subCats as $subcat) {&nbsp; &nbsp; if($i == 10) { break; } $i++;&nbsp; &nbsp; $_category = $objectManager->create('Magento\Catalog\Model\Category')->load($subcat->getId());&nbsp; &nbsp; $subcaturl = $subcat->getUrl();&nbsp; &nbsp; ?>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <li class="cat-li" style="list-style-type: none;">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="product-item-info">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <div class="product-item-details">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <ul class="productsub-categories" style="text-align: left;">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;<a href="<?php echo $subcaturl; ?>">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <strong ><?php echo $subcat->getName(); ?></strong>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </a>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </ul>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </div>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; </li>&nbsp; &nbsp; <?php }&nbsp; &nbsp; echo "Your view all link";
