magento从类别中获取产品,按rand()排序

Question

我有以下内容:

$products = Mage::getModel('catalog/product')
    ->getCollection()
    ->addAttributeToSort('id', 'RAND()')
    ->addAttributeToSelect('small_image')
    ->addCategoryFilter(Mage::getModel('catalog/category')->load($catId));

但我需要通过id订购RAND(),我该怎么做？(代码显示我是如何尝试没有运气的)

Answer 1

Magento集合不接受选定属性之外的参数.在这种情况下,您应该获取Zend_Db_Select对象并向其添加订单指令.

$products = Mage::getModel('catalog/product')
    ->getCollection()
    ->addAttributeToSort()
    ->addAttributeToSelect('small_image')
    ->addCategoryFilter(Mage::getModel('catalog/category')->load());
$products->getSelect()->order(new Zend_Db_Expr('RAND()'));

要查看将执行的查询,您可以使用此构造

$products->load(true, true); // first parameter show sql query in output, second show sql query in var/log/syslog

请参阅此问题:通过rand() 和clockworkgeek的答案查询magento limit + order:

$collection->getSelect()->order(new Zend_Db_Expr('RAND()'));
