magento产品详细页添加下一件、上一件产品链接

此代码放在你的magento系统的view.phtml文件中即可。
代码如下：
<?php
$_helper = $this->helper(‘catalog/output’);//如果view.phtml文件中已经存在，可不加
$_product = $this->getProduct();//如果view.phtml文件中已经存在，可不加
$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 $this->__(‘Prev’) ?>
</a>
<?php endif; ?>
</div>
<div class=”for-prev”>
<?php if ($url != $next_url):?>
<a class=”prev-product” href=”<?php echo $next_url; ?>”>
<?php echo $this->__(‘next’) ?>
</a>
<?php endif; ?>
</div>
</div>
