[原创] Magento 动态添加或修改商品的 Custom Option
最近在 Magento 项目中有这样一种需求，在下订单时，修改该商品的 Custom Option。现列出一下解决方案：测试时使用的 Magento 版本是 1.7.0.2。
动态修改商品的 Custom Option
$_product = $this->getProduct();$i = 1;foreach ($_product->getOptions() as $o) {echo "Custom Option:" . $i . "<br/>";echo "Custom Option TYPE: " . $o->getType() . "<br/>";echo "Custom Option TITLE: " . $o->getTitle() . "<br/>";echo "Custom Option Values: <br/>";// Getting Values if it has option values, case of select,dropdown,radio,multiselect$values = $o->getValues();foreach ($values as $v) {//print_r($v->getData());echo $v["title"] . " Sort Order: " . $v["sort_order"] . "<br/>";$rand = rand(0, 100);$v["sort_order"] = $rand;$v->setOption($o)->save();/* Or else, you can set multiple option value simultaneously.$v->setTitle("morad")->setSku("kk")->setPriceType("fixed")->setSortOrder(0)->setPrice(floatval(13.0000));$v->setOption($o)->save();*/}$i++;}
动态添加商品的 Custom Option
function setCustomOption($productId, $title, array $optionData, array $values = array()) { Mage::app()->getStore()->setId(Mage_Core_Model_App::ADMIN_STORE_ID); if (!$product = Mage::getModel('catalog/product')->load($productId)) { throw new Exception('Can not find product: ' . $productId); } $defaultData = array( 'type' => 'field', 'is_require' => 0, 'price' => 0, 'price_type' => 'fixed', ); $data = array_merge($defaultData, $optionData, array('product_id' => (int)$productId, 'title' => $title, 'values' => $values)); $product->setHasOptions(1)->save(); $option = Mage::getModel('catalog/product_option')->setData($data) ->setProduct($product)->save(); return $option;}
使用示例：
$options =array('type' => 'radio', 'is_require' => 1, 'price' => 0, 'price_type' => 'fixed'); $values = array( array( 'title' => '2kg', 'price' => 10, 'price_type' => 'fixed', 'sku' => 'w1', 'sort_order' => 1 ), array( 'title' => '4kg', 'price' => 20, 'price_type' => 'fixed', 'sku' => 'w2', 'sort_order' => 2 ), array( 'title' => '10kg', 'price' => 40, 'price_type' => 'fixed', 'sku' => 'w3', 'sort_order' => 3 ) ); setCustomOption(166, 'Weight', $options, $values);
