我用这段代码列出了子类别
$root = Mage::getModel('catalog/category')->load(3); // Put your category ID here.
$subCat = explode(',',$root->getChildren());
$collection = $root->getCollection()->addAttributeToSelect("*")->addFieldToFilter("entity_id", array("in", $subCat) );
foreach($collection as $subcategory) {
echo '<a href="'.$subcategory->getURL() .'" />» '.$subcategory->getName().'</a><br/>';
}
我想只显示前3个子类别.我该怎么做？
我需要为 body 标签添加一些数据属性。我怎样才能做到这一点？
<body data-spy="scroll" data-target=".navbar-nav" data-offset="110">
