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
<block type="catalog/product_rand1" name="left.rand.product.viewed" template="catalog/product/rand_product.phtml" />
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)
