EXTENSION NAME
==================================
Birthday fields and Automated Birthday Coupons v1.0

FEATURES
==================================
- This module allows your customers to enter their BIRTHDAY FIELD when they register (via Register page or Checkout page)
- Datepicker addon for fields, both in admin and front-end view
- The module also sends daily AUTOMATED BIRTHDAY COUPONS to customers, if it's their birthday, by generating random coupon codes
- It allows you to enter a Minimum Order amount to use and a custom Discount Percent for the Automated Birthday Coupon, in admin area for general Voucher settings. This gets sent daily, to all customers that are having birthdays
- The coupon can only be used 1 time, by 1 customer and only in the next 15 days from today (customer’s birthday).
- The script runs everyday, via a CRON JOB that you will have to setup in your Cpanel account

DESCRIPTION
==================================
- The email template used for vouchers is located in catalog\view\theme\default\template\mail\coupon.tpl but it can be replaced by adding to your custom theme a ‘coupon.tpl' file, so yes you can edit the e-mail template as you wish
- The coupon’s minimum order amount entered is calculated using the default admin currency (USD for example)
- If the front-end currency is different than admin, for example GBP, then amount sent to client gets converted from admin USD currency
- If an user has already received a coupon on birthday(today), it doesn't get sent anymore if the link gets accidently accessed or if the CRON JOB repeats somehow
- Coupon code is generated random, using the random PHP function, with microseconds feed
- The coupon can only be used 1 time, by 1 customer and only in the next 15 days from today (customer’s birthday).
- When sending emails, the default Open Cart email system is used, MAIL or SMTP, depending on your admin settings
- In order for the script to work daily, you need to set a CRON JOB via your hosting's Cpanel account and use the URL from READ-ME.txt file included
* This module is under development, any suggestions are welcomed, so contact me by email if needed.
