magento产品详细页添加返回分类链接，下一件，上一件产品链接

google了半天，找到了magento产品详细页添加返回分类目录链接，下一件，上一件产品链接的代码，贴在这里共享下。

我在magento 1.4.1.0上简单测试了下，没有发现什么问题，大家试试，有问题告诉我。

部分代码来源：http://www.magentocommerce.com/boards/viewthread/9946/P30/

此代码放在你的产品的view.phtml文件中即可。至于css自己补上吧，可以按照我的截图的样子放，比较方便。

代码如下：

<!--for next & prev link-->
<?php // prev- / next-link...
    $_helper = $this->helper('catalog/output');
    $_product = $this->getProduct();
    $prev_url = $next_url = $url = $_product->getProductUrl();

    if ($this->helper('catalog/data')->getCategory()) {
        $category = $this->helper('catalog/data')->getCategory();
    } else {
        $_ccats = $this->helper('catalog/data')->getProduct()->getCategoryIds();
        $category = Mage::getModel('catalog/category')->load($_ccats[0]);
    }

    $children = $category->getProductCollection();
    $_count = is_array($children) ? count($children) : $children->count();
    if ($_count) {
        foreach ($children as $product) {
            $plist[] = $product->getId();
        }

        /**
         * Determine the previous/next link and link to current category
         */
        $current_pid  = $this->helper('catalog/data')->getProduct()->getId();
        $curpos   = array_search($current_pid, $plist);
        // get link for prev product
        $previd   = isset($plist[$curpos+1])? $plist[$curpos+1] : $current_pid;
        $product  = Mage::getModel('catalog/product')->load($previd);
        $prevpos  = $curpos;
        while (!$product->isVisibleInCatalog()) {
            $prevpos += 1;
            $nextid   = isset($plist[$prevpos])? $plist[$prevpos] : $current_pid;
            $product  = Mage::getModel('catalog/product')->load($nextid);
        }
        $prev_url = $product->getProductUrl();
        // get link for next product
        $nextid   = isset($plist[$curpos-1])? $plist[$curpos-1] : $current_pid;
        $product  = Mage::getModel('catalog/product')->load($nextid);
        $nextpos  = $curpos;
        while (!$product->isVisibleInCatalog()) {
            $nextpos -= 1;
            $nextid   = isset($plist[$nextpos])? $plist[$nextpos] : $current_pid;
            $product  = Mage::getModel('catalog/product')->load($nextid);
        }
        $next_url = $product->getProductUrl();
    }
?>
<div class="prevNextcategoriesNavigation">
	<div class="for-next">
		<?php if ($url != $prev_url):?>
			<a class="next-product" href="<?php echo $prev_url; ?>">
				<?php echo $this->__('<- Prev') ?>
			</a>
		<?php endif; ?>
	</div>
	<div class="for-categories">
		<ul>
			<li> <?php echo $this->__('Back to Categories:') ?></li>
			<?php $categories = $_product->getCategoryIds(); ?>
			<?php foreach($categories as $k => $_category_id): ?>
			<?php $_category = Mage::getModel('catalog/category')->load($_category_id) ?>
			<li><a class="back-to-catalog" href="<?php echo $_category->getUrl() ?>"><?php echo $_category->getName() ?></a></li>
			<?php endforeach; ?>
		</ul>
	</div>
	<div class="for-prev">
		<?php if ($url != $next_url):?>
			<a class="prev-product" href="<?php echo $next_url; ?>">
				<?php echo $this->__('next ->') ?>
			</a>
		<?php endif; ?>
	</div>
</div>
<!--for next & prev link-->

请大家注意自己的magento版本，可能因为版本原因需要调试代码。
