如下图所示：
magento产品详细页返回分类链接，上一个下一个产品链接
部分代码来源：http://www.magentocommerce.com/boards/viewthread/9946/P30/
将此代码放在你的Magento系统\app\design\frontend\default\Your_Template\template\catalog\product\view.phtml文件中
<?php
$_helper = $this->helper(‘catalog/output’);
$_product = $this->getProduct();
?>下一行即可。
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);
