如何按子类别对分类页面上的产品进行排序，并限制每个子类别中的产品数量:
例如，如果类别是Food，我希望显示以下内容:
饮料可乐12盎司，橙汁8盎司，牛奶加仑，
意大利面，意大利面1lb，香蒜沙司12个，意大利饺子1个
依此类推，显示每个子类别名称后面跟着3个产品(图像等)
我目前有一个自定义模板，可以显示子类别，但不能找出产品，
<?php
$_category = $this->getCurrentCategory();
$collection = $_category->getCollection()
->addAttributeToSelect(
array('url_key','name','all_children','is_anchor','description','image')
)
->addAttributeToFilter('is_active', 1)
->addIdFilter($_category->getChildren())
->setOrder('position', 'ASC')
->joinUrlRewrite();
$helper = Mage::helper('catalog/category');
?>
<ul>
<?php foreach ($collection as $cat): ?>
<li>
<div class="level1descript">
<a href="<?php echo $helper->getCategoryUrl($cat); ?>">
<img src="<?php echo $cat->getImageUrl(); ?>" class="catlevel1image" />
<h2><?php echo $cat->getName(); ?></h2>
</a>
<p class="level1descript">
<?php
$catdesc = '';
$catdesc = strip_tags($cat->getDescription());
if (strlen($catdesc) > 300) {
$catdesc = substr($catdesc, 0, 300) . ' ...';
}
echo $catdesc;
?>
</p>
</div>
<?php
$childLevel2Category = $cat->getCollection()
->addAttributeToSelect(
array('url_key','name','all_children','is_anchor','description','image')
)
->addAttributeToFilter('is_active', 1)
->addIdFilter($cat->getChildren())
->setOrder('position', 'ASC')
->joinUrlRewrite();
?>
<ul>
<?php foreach ($childLevel2Category as $catLevel2) { ?>
<li class="level2cats">
<a href="<?php echo $helper->getCategoryUrl($catLevel2); ?>">
<img src="<?php echo $catLevel2->getImageUrl(); ?>" class="catlevel2image" />
<h4><?php echo $catLevel2->getName(); ?></h4>
</a>
<p class="level2descript">
<?php
$catdesc = '';
$catdesc = strip_tags($catLevel2->getDescription());
if (strlen($catdesc) > 60) {
$catdesc = substr($catdesc, 0, 60) . ' ...';
}
echo $catdesc;
?>
</li>
<?php } ?>
</ul>
</li>
<?php endforeach;?>
</ul>
下面我记录了一个想法，我认为这是一个想法。请原谅我的笨拙风格。因为我只是用我正在做的一个项目把它放在一起。有问题请提。setPageSize方法将拉出默认情况下在子类别中显示的前3个产品。
