我的产品尺寸可变，影响重量，我需要将重量逻辑放在购物车中，以便更准确地计算运费。我已将 app / code / core / Mage / Sales / Model / Quote / Item.php 的副本移动到本地代码池。我已经能够获取相关产品的基本重量，但是，在更新购物车之前，我无法获得自定义选项（文本字段）值来进行数学计算。我在公共函数setProduct中执行此操作。这是我到目前为止所做的：
public function setProduct($product)
{
if ($this->getQuote()) {
$product->setStoreId($this->getQuote()->getStoreId());
$product->setCustomerGroupId($this->getQuote()->getCustomerGroupId());
}
//Get the Weight per UOM
$sku = $product->getSku();
$item = Mage::getModel('catalog/product')->loadByAttribute('sku',$sku);
$wpuom = $item->getResource()->getAttribute('weight_per_uom')->getFrontend()->getValue($item);
//Get the Length
$params = Mage::app()->getRequest()->getParams();
/** @var Mage_Catalog_Model_Product $product */
$info = new Varien_Object($params);
// Don't throw an exception if required options are missing
$processMode = Mage_Catalog_Model_Product_Type_Abstract::PROCESS_MODE_LITE;
$options = array();
foreach ($product->getOptions() as $option) {
/* @var $option Mage_Catalog_Model_Product_Option */
$group = $option->groupFactory($option->getType())
->setOption($option)
->setProduct($product)
->setRequest($info)
->setProcessMode($processMode)
->validateUserValue($info->getOptions());
$optionValue = $info->getData('options/' . $option->getId());
$options[] = array(
'label' => $option->getTitle(),
'value' => $group->getFormattedOptionValue($optionValue),
'value2' => $option->getValues(),
'option_id' => $option->getId(),
'option_type' => $option->getType()
);
//<<<This is Where I Cannot Get the Value for the Custom Option>>>
if($options[0]['label'] == 'Length') {
//print_r($options[0]['value']);
}
}
//Update Weight
$baseWeight = $item->getWeight();
$uom = $item->getResource()->getAttribute('uom')->getFrontend()->getValue($item);
if((($uom == 'Meters') && ($length >= 76)) || (($uom == 'Feet') && ($length >= 250))) { $spoolWeight = 3; }
else { $spoolWeight = 0; }
$finalWeight = ($baseWeight + ($length * $wpuom) + $spoolWeight);
$this->setData('product', $product)
->setProductId($product->getId())
->setProductType($product->getTypeId())
->setSku($this->getProduct()->getSku())
->setName($product->getName())
->setWeight($this->getProduct()->getWeight())
->setTaxClassId($product->getTaxClassId())
->setBaseCost($product->getCost())
->setIsRecurring($product->getIsRecurring());
if ($product->getStockItem()) {
$this->setIsQtyDecimal($product->getStockItem()->getIsQtyDecimal());
}
Mage::dispatchEvent('sales_quote_item_set_product', array(
'product' => $product,
'quote_item' => $this
));
return $this;
}
当我尝试添加print_r($options[0]);时，除了值之外，我得到了所有内容，它甚至都不是数组。为了获得价值，我错过了什么？

如果您在网站上的各个位置显示产品价格，例如网站上的类别页面，心愿单和其他区域，您可能会遇到心愿单和其他功能的问题。
话虽如此，我对您的代码进行了一些修改并在下面进行了更新。我采用了略微不同的方法来获得最终结果。首先，获取当前会话的所有购物车项目。如果产品类型是可配置的，那么执行一些逻辑，如果没有，则执行其他逻辑。在逻辑内部，我收集项目，关联的属性值，自定义选项和自定义选项值。我还添加了一些功能来为sku添加长度和度量单位。然后我继续展示了如何使用直接mySQL查询来更新数据库的示例，包括新的定价，skus，权重和其他详细信息。
public function setProduct($product)
{
if ($this->getQuote()) {
$product->setStoreId($this->getQuote()->getStoreId());
$product->setCustomerGroupId($this->getQuote()->getCustomerGroupId());
}
$quote = Mage::getSingleton('checkout/session')->getQuote();
foreach ($quote->getAllVisibleItems() as $itm){
$sku = $product->getSku();
$item = Mage::getModel('catalog/product')->loadByAttribute('sku',$sku);
$assocProd = Mage::getModel('catalog/product')->loadByAttribute('sku',$itm->getSku());
if($product->getTypeId() == 'configurable') { //configurable product
foreach ($product->getOptions() as $o) {
if($o->getTitle() == "YOUR CUSTOM OPTION LABEL" && $o->getType() == "field"){
$optionId = $o->getOptionId();
$opz = $itm->getOptionByCode('info_buyRequest');
$buyRequest = new Varien_Object($opz ? unserialize($opz->getValue()) : null);
foreach($buyRequest['options'] as $key => $value){
if($key == $optionId) {
$length = $value;
//here is your length... do with it what you please
}
//example of how to update the database
$itemId = $itm->getId();
$query = 'UPDATE `sales_flat_quote_item` SET `weight` = "'.$finalWeight.'", `display_sku` = "'.$displaySku.'" WHERE `item_id` = "'.$itemId.'"';
$resource = Mage::getSingleton('core/resource');
$writeConnection = $resource->getConnection('core_write');
$writeConnection->query($query);
}
}
}
}
}
else { //simple product
if($product->getOptions()) { //has options
foreach ($product->getOptions() as $o) {
if($o->getTitle() == "YOUR OPTION LABEL" && $o->getType() == "field"){
$optionId = $o->getOptionId();
$opz = $itm->getOptionByCode('info_buyRequest');
$buyRequest = new Varien_Object($opz ? unserialize($opz->getValue()) : null);
foreach($buyRequest['options'] as $key => $value){
$finalWeight = '';
if($key == $optionId) {
$length = $value;
//here's your length value for simple products
}
//to update the database
$itemId = $itm->getId();
$query = 'UPDATE `sales_flat_quote_item` SET `weight` = "'.$finalWeight.'", `display_sku` = "'.$displaySku.'" WHERE `item_id` = "'.$itemId.'"';
$resource = Mage::getSingleton('core/resource');
$writeConnection = $resource->getConnection('core_write');
$writeConnection->query($query);
}
}
}
}
}
else { //doesn't have options
//this would be your logic for a simple product with no options
}
}
如果您有任何问题，我希望这有帮助并随时告诉我们！
