我有一个new.phtml文件和new.php文件，我确信主页上显示的产品仅来自这些文件。目前只有6种产品正在展出。我只是想知道如何能够显示更多的产品（应该以3的乘法递增），如9,12,15等。 我试图将两个文件中的所有'6'替换为'9'，但我无法得到我正在寻找的东西？请任何人帮助我，给我一些技巧！ 这是new.php文件代码：
class Mage_Catalog_Block_Pro duct_New extends Mage_Catalog_Block_Product_Abstract
{
protected $_productsCount = null;
const DEFAULT_PRODUCTS_COUNT = 5;
/**

{
parent::_construct();
$this->addColumnCountLayoutDepend('empty', 10)
->addColumnCountLayoutDepend('one_column', 5)

->addColumnCountLayoutDepend('three_columns', 3);
$this->addData(array(

Here is my new.phtml file:
<?php $_helper = $this->helper('catalog/output'); ?>
<?php if (($_products = $this->getProductCollection()) && $_products->getSize()): ?>
<?php $_columnCount = 3 ?>

<div class="block-new">
<div class="clear"></div>
<div class="block-content">
<?php $m=1; ?>
<?php $i=0; foreach ($_products->getItems() as $_product): ?>
<?php if ($i++%$_columnCount==0 ): ?>

<?php endif ;?>
<li class="item<?php if(($i-1)%$_columnCount==0): ?> first<?php elseif($i%$_columnCount==0): ?> last<?php endif; ?>">
<a href="<?php echo $_product->getProductUrl() ?>" title="<?php echo $this->htmlEscape($_product->getName()) ?>" class="product-image"><img src="<?php echo $this->helper('catalog/image')->init($_product, 'small_image')->resize(160) ?>" width="160" height="160" alt="<?php echo $this->htmlEscape($_product->getName()) ?>" /></a>

<?php echo $this->getReviewsSummaryHtml($_product, 'short') ?>
</div>
<div class="new-des">
<?php
$position=50; // Define how many character you want to display.

有两种方法可以控制产品的编号。
1如果您使用的是通用magento loadedcollection，您可以更改
中的值System -> Configuration -> Catalog -> Frontend tab
2如果您使用自定义代码来获取产品
您可以添加setize和setpage方法来限制收集ex：
$collection = Mage::getModel('...')
->getCollection()
->setPageSize(20)
->setCurPage(1);
OR
$collection = Mage::getModel('...')->getCollection();
$collection->getSelect()->limit(20);
3根据您使用页面的方式，您还可以从布局XML设置产品限制 例如：
<block type="catalog/product_list" name="bestsellers">
<action method="setLimit"><value>3</value></action>
</block>
我希望上面的任何一个可以帮助你。

尝试使用以下代码设置magento主页中的产品数量
{{block type="catalog/product_new" category_id="3" products_count="9" name="home.catalog.product.new" alias="product_homepage" template="catalog/product/new.phtml" }}
