我正在按父类别ID显示子类别列表,并希望显示类别图像来代替类别名称。
这是我迄今为止所拥有的。。。
<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>
我试过无数种方法来显示图像来代替类别名称,但似乎没有什么能让图像出现。目前,对于上面的内容,输出是一个空的"img src",所以我正在尝试的内容显然存在错误(可能是实现我想要的内容的更好方法)。
请有人指出问题出在哪里好吗?
如果它有任何相关性,我以后打算做的是以网格格式显示类别图像(每行3或4个)。
非常感谢。
一个更快的解决方案是使用B00MER这样的ID过滤器将图像属性添加到集合中:
// 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-请参阅下面的修复程序。
<?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 $data['img']; ?>" />
</a>
</li>
<?php endforeach; ?>
</ul>
令人惊讶的是,我们没有得到更多的支持,因为这是一个相对简单的Magento问题。感谢B00MER的回复。
试试这个方法,而不是$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();
}
}
