Thanks, Jitendra

for your information the code is here....

function generateUniqueId($length = null)
    {
        $rndId = crypt(uniqid(rand(),1));
        $rndId = strip_tags(stripslashes($rndId));
        $rndId = str_replace(array(".", "$"),"",$rndId);
        $rndId = strrev(str_replace("/","",$rndId));
            if (!is_null($rndId)){
            return strtoupper(substr($rndId, 0, $length));
            }
        return strtoupper($rndId);
    }
    /* create unique coupan code */

        $productId  = (int) $this->getRequest()->getParam('id'); 
        $discountprice=$_POST['product']['discountprice']; 
        $model = Mage::getModel('salesrule/rule');
        $couponCode=generateUniqueId(8);
        $model->setName($couponCode);
        $model->setDescription('Discount coupon for Surger.');
        $model->setUsesPerCoupon(1);
        $model->setUsesPerCustomer(1);
        $model->setCustomerGroupIds('0,1');
        $model-&开发者_Go百科gt;setIsActive(1);
       // $model->setConditionsSerialized('a:6:{s:4:\"type\";s:32:\"salesrule/rule_condition_combine\";s:9:\"attribute\";N;s:8:\"operator\";N;s:5:\"value\";s:1:\"1\";s:18:\"is_value_processed\";N;s:10:\"aggregator\";s:3:\"all\";}');

        $model->setStopRulesProcessing(0);
        $model->setIsAdvanced(1);
       // $model->setProductIds($productId);
        $model->setSortOrder('0');
        $model->setSimpleAction('by_percent');
        $model->setDiscountAmount($discountprice);
        $model->setDiscountStep(0);
        $model->setSimpleFreeShipping(0);
        $model->setCouponType(2);
        $model->setCouponCode($couponCode);
        $model->setUsesPerCoupon(1);
        $model->setTimesUsed(0);
        $model->setIsRss(0);
        $model->setWebsiteIds('1');
        $model->save();

Here is the perfect code for applying discount to specific product..I found the solution..This code is working fine for applying discount to specific product.

function generateUniqueId($length = null)
    {
        $rndId = crypt(uniqid(rand(),1));
        $rndId = strip_tags(stripslashes($rndId));
        $rndId = str_replace(array(".", "$"),"",$rndId);
        $rndId = strrev(str_replace("/","",$rndId));
            if (!is_null($rndId)){
            return strtoupper(substr($rndId, 0, $length));
            }
        return strtoupper($rndId);
    }
    /* create unique coupan code */
        $productId  = (int) $this->getRequest()->getParam('id'); 
        $sku=$this->getRequest()->getParam('sku');
        $discountprice=$_POST['product']['discountprice']; 
        $model = Mage::getModel('salesrule/rule');

        $model->setTimesUsed(0);
        $model->setIsRss(0);
        $model->setWebsiteIds('1');

         $sku=$_POST['product']['sku'];

anybody knows how to apply this discount for one product only what happens in following case is that the discount goes to grand total but i want to apply this discount to that product which i have entered the discount code can anybody help me to separate this discount.

please help...

thanks, Jitendra

From what I can tell of the discount system you will need to do the following before saving the rule. As you can see it works by searching for any cart product with a specific SKU.

$sku = 'ABCD';            // Put your product SKU here
$found = Mage::getModel('salesrule/rule_condition_product_found')
         ->setType('salesrule/rule_condition_product_found')
         ->setValue(1)           // 1 == FOUND
         ->setAggregator('all'); // match ALL conditions
$model->getConditions()->addCondition($found);
$skuCond = Mage::getModel('salesrule/rule_condition_product')
           ->setType('salesrule/rule_condition_product')
           ->setAttribute('sku')
           ->setOperator('==')
           ->setValue($sku);
$found->addCondition($skuCond);

This is the answer of my own question:
