开发magento增加优惠劵以及规则的方法_magento教程_php教程

magento 后台有相应的优惠券等功能，如果我们需要自己开发该类功能，不用后台功能，更简洁的应在magento主题模板上。可以采用以下代码：

<?php

// load product

/** @var Mage_Catalog_Model_Product $product */

$product = Mage::getModel('catalog/product')

->setStoreId($storeId)

->load($productId);

// set length of coupon code

/** @var Mage_SalesRule_Model_Coupon_Codegenerator $generator */

$generator = Mage::getModel('salesrule/coupon_codegenerator')

->setLength(8);

/** @var Mage_SalesRule_Model_Rule_Condition_Product $conditionProduct */

$conditionProduct = Mage::getModel('salesrule/rule_condition_product')

->setType('salesrule/rule_condition_product')

->setAttribute('sku')

->setOperator('==')

->setValue($product->getSku());

/** @var Mage_SalesRule_Model_Rule_Condition_Product_Found $conditionProductFound */

$conditionProductFound = Mage::getModel('salesrule/rule_condition_product_found')

->setConditions(array($conditionProduct));

/** @var Mage_SalesRule_Model_Rule_Condition_Combine $condition */

$condition = Mage::getModel('salesrule/rule_condition_combine')

->setConditions(array($conditionProductFound));

/** @var Mage_SalesRule_Model_Coupon $coupon */

$coupon = Mage::getModel('salesrule/coupon');

// try to generate unique coupon code

$attempts = 0;

do {

if ($attempts++ >= 8) {

Mage::throwException(Mage::helper('mymodule')->__('Unable to create requested Coupons. Please try again.'));

}

$code = $generator->generateCode();

} while ($coupon->getResource()->exists($code));

// create rule

/** @var Mage_SalesRule_Model_Rule $rule */

$rule = Mage::getModel('salesrule/rule');

$rule->setName(Mage::helper('mymodule')->__('Name of the coupon'))

->setDescription($rule->getName())

->setFromDate(date('Y-m-d'))

->setCustomerGroupIds($this->_getCustomerGroups())

->setIsActive(1)

->setConditionsSerialized(serialize($condition->asArray()))

//->setActionsSerialized

//->setStopRulesProcessing

//->setIsAdvanced

->setSimpleAction(Mage_SalesRule_Model_Rule::BY_FIXED_ACTION)

->setDiscountAmount($product->getFinalPrice())

->setDiscountQty(1)

//->setDiscountStep

->setStopRulesProcessing(0)

->setIsRss(0)

->setWebsiteIds(array(1))

->setCouponType(Mage_SalesRule_Model_Rule::COUPON_TYPE_SPECIFIC)

->setConditions($condition)

->save();

// create coupon

$coupon->setId(null)

->setRuleId($rule->getRuleId())

->setCode($code)

->setUsageLimit(1)

//->setUsagePerCustomer

//->setTimesUsed

//->setExpirationDate

->setIsPrimary(1)

->setCreatedAt(time())

->setType(Mage_SalesRule_Helper_Coupon::COUPON_TYPE_SPECIFIC_AUTOGENERATED)

->save();
