As mentioned previously, I use a service called Spreedly to manage subscriptions in NeoBudget. I also created and maintain the Spreedly PHP library.
Thanks to the contributions of some fellow Spreedly customers, and due to some recent enhancements from Spreedly, I’ve released v2.5 of the Spreedly PHP library.
This release includes the new extended options available for the Spreedly::get_subscribe_url() method explained in the Spreedly integration reference. The most notable improvement is the inclusion of the subscriber token as a way to pre-populate the form fields with data already entered.
This is a backwards compatible release, meaning that although new functionality was added, old functionality has not been broken. Check out the Spreedly PHP library page to download.
