I want to make a coupon time bound if a user registers on the website I will send him a coupon e.g. : CHJU20 that will be valid for only one month from the date of registering.

It should not apply after 1 month. Now if a new customer registers the same should happen with him too

I have created coupon code programmatically.

First of all you need to create shopping cart price rule in Magento Admin >> Promotions >> Shopping Cart Price Rules

Make sure coupon code should be auto generated. So you must have to select Use Auto Generation as per below screen shot.

Then you can use below code.

<?php

$rule = Mage::getModel('salesrule/rule')->load(1); //1 = ID of coupon 

$generator = Mage::getModel('salesrule/coupon_massgenerator');

$parameters = array(

    'count' => 1,

    'format' => 'alphanumeric',

    'prefix' => 'A', // if you require

    'suffix' => 'B', // if you require

    'length' => 6,

    'from_date' => '18/11/2017',

    'to_date' => '12/12/2017', // if require end date

);



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;

  }

}

$generator->setLength(!empty($parameters['length']) ? (int) $parameters['length'] : 6);

$generator->setPrefix(!empty($parameters['prefix']) ? $parameters['prefix'] : '');

$generator->setSuffix(!empty($parameters['suffix']) ? $parameters['suffix'] : '');





$rule->setCouponCodeGenerator($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;

}
