我按父类别ID显示子类别列表,我希望显示类别图像而不是类别名称。
这是我到目前为止所拥有的......
<div id="menu_brands">
<div class="brand_head">
<h3><?php echo $this->__('Browse By Brand') ?></h3>
</div>
<div class="brand_list">
<?php
$cats = Mage::getModel('catalog/category')->load(6)->getChildren();
$catIds = explode(',',$cats);
$categories = array();
foreach($catIds as $catId) {
$category = Mage::getModel('catalog/category')->load($catId);
$categories[$category->getName()] = $category->getUrl();
$img = $category->getImageUrl(); //I suspect this line is wrong
}
ksort($categories, SORT_STRING);
?>
<ul>
<?php foreach($categories as $name => $url): ?>
<li>
<!--<a href="<?php echo $url; ?>"><?php echo $name; ?></a>-->
<a href="<?php echo $url; ?>" title="<?php echo $name; ?>">
<img src="<?php echo $img; ?>" width="auto" alt="<?php echo $name; ?>" /> <!--I suspect this line is wrong-->
</a>
</li>
<?php endforeach; ?>
</ul>
</div>
</div>
我尝试了无数种方式来显示图像来代替类别名称,但似乎没有任何方法可以显示图像。目前有上述内容,输出是一个空的'img src',所以我正在尝试的内容显然是错误的(并且可能是实现我所追求的更好的方法)。
有人可以指出问题是什么吗?
如果它有任何相关性,那么我打算在之后做的是以网格格式显示类别图像(每行3或4个)。
非常感谢提前。

zigojacko的解决方案并不理想,因为它在循环中单独加载模型。这不能很好地扩展,并且许多类别会破坏您的数据库。理想情况下,您可以将图像添加到子集合中。
更快的解决方案是将图像属性添加到具有ID过滤器的集合,如B00MER:
// Gets all sub categories of parent category 'Brands'
$parent = Mage::getModel('catalog/category')->load(6);
// Create category collection for children
$childrenCollection = $parent->getCollection();
// Only get child categories of parent cat
$childrenCollection->addIdFilter($parent->getChildren());
// Only get active categories
$childrenCollection->addAttributeToFilter('is_active', 1);
// Add base attributes
$childrenCollection->addAttributeToSelect('url_key')
->addAttributeToSelect('name')
->addAttributeToSelect('all_children')
->addAttributeToSelect('is_anchor')
->setOrder('position', Varien_Db_Select::SQL_ASC)
->joinUrlRewrite();
// ADD IMAGE ATTRIBUTE
$childrenCollection->addAttributeToSelect('image');
?>
<ul>
<?php foreach($childrenCollection as $cat): ?>
<li>
<a href="<?php echo $cat->getURL(); ?>" title="<?php echo $cat->getName(); ?>">
<img class="cat-image" src="<?php echo $cat->getImageUrl(); ?>" />
</a>
</li>
<?php endforeach; ?>
</ul>

我们自己设法解决了这个问题 - 请参阅下面的修复。
<?php
//gets all sub categories of parent category 'Brands'
$cats = Mage::getModel('catalog/category')->load(6)->getChildren();
$catIds = explode(',',$cats);
$categories = array();
foreach($catIds as $catId) {
$category = Mage::getModel('catalog/category')->load($catId);
$categories[$category->getName()] = array(
'url' => $category->getUrl(),
'img' => $category->getImageUrl()
);
}
ksort($categories, SORT_STRING);
?>
<ul>
<?php foreach($categories as $name => $data): ?>
<li>
<a href="<?php echo $data['url']; ?>" title="<?php echo $name; ?>">
<img class="cat-image" src="<?php echo $data['img']; ?>" />
</a>
</li>
<?php endforeach; ?>
</ul>
感到惊讶的是,我们没有得到更多支持,因为它是一个相对简单的Magento问题。感谢B00MER的回答。

尝试使用此方法,而不是$img = $category->getImageUrl();
到$img = getCategoryImage($category);
function getCategoryImage($category) {
$categoryCollection = Mage::getModel('catalog/category')->setStoreId(Mage::app()->getStore()->getId())->getCollection()->addAttributeToSelect('image')->addIdFilter($category->getId());
foreach($categoryCollection as $category) {
return $category->getImageUrl();
}
}
