magento详细产品页调用上级目录产品,magento调用上级目录产品_Magento教程

因为我是新手，写的比较啰嗦。。。按下面的步骤，一定可以能成功调出。。。

第一步：创建一个rand_product.phtml

1.phtml（app\design\frontend\base\default\template\catalog\product\rand_product.phtml）
如下代码

<?php if (($_products = $this->getProductCollection()) && $_products->getSize()): ?>
<h2><?php echo $this->__('Related Products') ?></h2>
<?php $_columnCount = 4; ?>
    <?php $i=0; foreach ($_products->getItems() as $_product): ?>
        <?php if ($i++%$_columnCount==0): ?>
        <ul>
        <?php endif ?>
            <li>
                <a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($_product->getName()) ?>">
<img src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(100,159) ?>" width="100" height="159" alt="<?php echo $this->htmlEscape($_product->getName()) ?>" /></a>
                <?php echo $this->getPriceHtml($_product, true, '-new') ?>
            </li>
        <?php if ($i%$_columnCount==0 || $i==count($_products)): ?>
        </ul>
        <?php endif ?>
    <?php endforeach; ?>
<?php endif; ?>

第二步：在catalog.xml里面加入下面这个块
2.xml

3.phtml调用：在view.phtml页面调用

<?php echo $this->getChildHtml('left.rand.product.viewed') ?>

创建一个文件Rand1.php,在下面的目录
4. php(app\code\core\Mage\Catalog\Block\Product\Rand1.php)
