Question

这是我的代码，

$collection = Mage::getModel('catalog/product')
            ->getCollection()
            ->setStoreId($storeId)
            ->addStoreFilter($storeId)
            ->addAttributeToFilter('status', 1)
            ->addAttributeToFilter('visibility', 4)
            ->addCategoryFilter(Mage::getModel('catalog/category')->load(500))
            ->addAttributeToSort('created_at', 'desc');
$collection->getSelect()->order(new Zend_Db_Expr('RAND()'));
$collection->setPageSize(20);

因为这个我得到随机20产品，但我想它应该从前20个产品中提供一个产品，从第二个20个产品中提供一个产品...... 20个产品。

我该怎么做？

任何想法？

我相信这样的事情可以帮助你，祝你好运= D

<?php
    $collection = Mage::getModel('catalog/product')
            ->getCollection()
            ->setStoreId($storeId)
            ->addStoreFilter($storeId)
            ->addAttributeToFilter('status', 1)
            ->addAttributeToFilter('visibility', 4)
            ->addCategoryFilter(Mage::getModel('catalog/category')->load(500))
            ->addAttributeToSort('created_at', 'desc');
    $collection->getSelect()->order(new Zend_Db_Expr('RAND()'));
    $collection->setPageSize(20);

    $array = array();
    foreach ($collection as $product) {
        $array[] = $product->getId();   
    }
    $rand = rand(0,19);
    do {
        $rand2 = rand(0,19);
    } while ($rand2 == $rand);

    $produc1 = Mage::getModel('catalog/product')->load($array[$rand]);
    $produc2 = Mage::getModel('catalog/product')->load($array[$rand2]); 
?>

为集合中的每20个产品选择一个随机产品
