如何在magento中顯示自定義選項的價格範圍

Question

我正在使用magento 1.7，在產品明細價格上我有一些自定義選項和一些可配置的產品選項。

我想要做的是我要顯示範圍內所有選項的價格，如最低總價格選項爲18.50，最高總價格選項爲55.90，則應顯示在產品頁面上某處，例如「 18.50 - 55.90「。

在此先感謝。

試試下面的代碼

//load configurable product  
$product = Mage::getModel('catalog/product')->load(some_id); 
//load all children 
$childProducts = Mage::getModel('catalog/product_type_configurable') 
        ->getUsedProducts(null,$product); 
foreach($childProducts as $child){ 
    $_child = Mage::getModel('catalog/product')->load($child->getId()); 
    $childPrice = $_child->getPrice(); 
    //compare the $childPrice 
} 

或在線查詢應該是這樣

<?php 
    $db = Mage::getSingleton('core/resource')->getConnection('core_write'); 
    $result = $db->query('SELECT a.product_id, a.product_super_attribute_id, ap.product_super_attribute_id, ap.pricing_value FROM catalog_product_super_attribute AS a INNER JOIN catalog_product_super_attribute_pricing AS ap ON a.product_super_attribute_id=ap.product_super_attribute_id WHERE a.product_id='.$_product->getId().' ORDER BY ap.pricing_value DESC LIMIT 1'); 
    $rows = $result->fetch(); 
    echo 'From '.Mage::helper('core')->currency($_product->getPrice()).' to '.Mage::helper('core')->currency($rows ['pricing_value']+$_product->getPrice()); 
?> 

編輯（可選）

$prices = array(); 
$associated = $_product->getTypeInstance(true)->getAssociatedProductCollection($_product) 
->addAttributeToSelect('special_pric$ 
foreach ($associated as $assoc) { 
    $prices[] = $assoc->getSpecialPrice(); 
} 
if (count($prices)) { 
    $min_price = min($prices); 
    $max_price = max($prices); 
} else { 
    $min_price = 0; 
    $max_price = 0; 
}
