Programmatically create automatically generated coupon codes in Magento?

Question

Based on other stackoverflow posts, I was able to use the following code to programmatically create individual shopping cart rule coupons in Magento.

How can I programmatically call the "Auto generate coupon" function to create 100 unique coupons for each price rule that I make? Thanks!

$coupon = Mage::getModel('salesrule/rule'); $coupon->setName($_coupon['name']) ->setDescription('this is a description') ->setFromDate(date('Ym-d')) ->setCouponType(2) ->setCouponCode($_coupon['code']) ->setUsesPerCoupon(1000) ->setUsesPerCustomer(100) ->setCustomerGroupIds(array(1)) //an array of customer groupids ->setIsActive(1) //serialized conditions. the following examples are empty ->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";}') ->setActionsSerialized('a:6:{s:4:"type";s:40:"salesrule/rule_condition_product_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";}') ->setStopRulesProcessing(0) ->setIsAdvanced(1) ->setProductIds('') ->setSortOrder(0) ->setSimpleAction('by_percent') ->setDiscountAmount(100) ->setDiscountQty(null) ->setDiscountStep('0') ->setSimpleFreeShipping('0') ->setApplyToShipping('0') ->setIsRss(0) ->setWebsiteIds(array(1)); $coupon->save(); 

For example, this one price rule may contain a complete list of auto-generated coupon codes (htgf-7774, htgf-2345, etc.) using the function available when manually creating price rules in the admin panel.

EDIT:

I came closer using the following code. Still don't know how to specifically assign a generation template

 ->setName('Name') ->setDescription('this is a description') ->setFromDate('2013-03-06') ->setToDate(NULL) ->setUsesPerCustomer('100') ->setIsActive('1') ->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";}') ->setActionsSerialized('a:6:{s:4:"type";s:40:"salesrule/rule_condition_product_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";}') ->setStopRulesProcessing('0') ->setIsAdvanced('1') ->setProductIds(NULL) ->setSortOrder('0') ->setSimpleAction('by_percent') ->setDiscountAmount('100.0000') ->setDiscountQty(NULL) ->setDiscountStep('0') ->setSimpleFreeShipping('0') ->setApplyToShipping('0') ->setTimesUsed('1') ->setIsRss('0') ->setCouponType('2') ->setUseAutoGeneration('1') ->setUsesPerCoupon('1000') ->setCustomerGroupIds(array('1',)) ->setWebsiteIds(array('1',)) ->setCouponCode(NULL)

Thanks to the excellent post that I found while searching on google ( http://fragmentedthought.com/fragments/programatically-creating-sales-rule-coupon-code ), I answered my question:

 // Get the rule in question $rule = Mage::getModel('salesrule/rule')->load(21); //21 = ID of coupon in question // Define a coupon code generator model instance // Look at Mage_SalesRule_Model_Coupon_Massgenerator for options $generator = Mage::getModel('salesrule/coupon_massgenerator'); $parameters = array( 'count'=>5, 'format'=>'alphanumeric', 'dash_every_x_characters'=>4, 'prefix'=>'ABCD-EFGH-', 'suffix'=>'-WXYZ', 'length'=>8 ); if( !empty($parameters['format']) ){ switch( strtolower($parameters['format']) ){ case 'alphanumeric': case 'alphanum': $generator->setFormat( Mage_SalesRule_Helper_Coupon::COUPON_FORMAT_ALPHANUMERIC ); break; case 'alphabetical': case 'alpha': $generator->setFormat( Mage_SalesRule_Helper_Coupon::COUPON_FORMAT_ALPHABETICAL ); break; case 'numeric': case 'num': $generator->setFormat( Mage_SalesRule_Helper_Coupon::COUPON_FORMAT_NUMERIC ); break; } } $generator->setDash( !empty($parameters['dash_every_x_characters'])? (int) $parameters['dash_every_x_characters'] : 0); $generator->setLength( !empty($parameters['length'])? (int) $parameters['length'] : 6); $generator->setPrefix( !empty($parameters['prefix'])? $parameters['prefix'] : ''); $generator->setSuffix( !empty($parameters['suffix'])? $parameters['suffix'] : ''); // Set the generator, and coupon type so it able to generate $rule->setCouponCodeGenerator($generator); $rule->setCouponType( Mage_SalesRule_Model_Rule::COUPON_TYPE_AUTO ); // Get as many coupons as you required $count = !empty($parameters['count'])? (int) $parameters['count'] : 1; $codes = array(); for( $i = 0; $i < $count; $i++ ){ $coupon = $rule->acquireCoupon(); $code = $coupon->getCode(); $codes[] = $code; } return $codes; 

This successfully generated the following codes:

 ABCD-EFGH-ZC6V-ZJWD-WXYZ ABCD-EFGH-4XMX-353L-WXYZ ABCD-EFGH-XCJB-5GQI-WXYZ ABCD-EFGH-UEAO-L1NJ-WXYZ ABCD-EFGH-59B3-50T2-WXYZ
