Our first open-source release: an e-commerce library for using PayPal with CodeIgniter

March 2nd, 2011 by Alex

A significant proportion of the work we do at Keplar involves helping companies to build out their ecommerce propositions. For speed and flexibility much of this work is done in PHP – or rather on well-established open-source technologies, such as CodeIgniter, MODx and Magento, which are built atop PHP.

To keep costs down for our clients and avoid “reinventing the wheel”, where possible we make use of existing libraries, plugins and extensions for these platforms. However this isn’t always possible, and sometimes we see an opportunity to improve (hopefully!) on the existing options.

At Keplar we’re keen to open-source any such code which we develop and own ourselves (i.e. isn’t part of a client deliverable) which we think could be useful for a wider audience. Open sourcing in-house technology has two clear benefits in our eyes: firstly it helps to support the open source ecosystems on which we depend, and secondly, the more eyes we can get on the code we use in the wild the better.

As our first tentative steps down this route, we are open sourcing a PayPal e-commerce library for CodeIgniter which we are already using in production on a couple of clients. We are releasing this library under the guise of an initiative which we are calling “Orderly” – we hope to release other e-commerce software and libraries under this banner in the future.

In our previous blog post in the Curated Web series, we looked at the various types of vertical search site, how they make money and where they get their search results from. We touched briefly on affiliate marketers, mentioning the affiliate networks which they belong to and the affiliate fees which they earn. In this post we dive much more deeply into affiliate marketing, to understand why retailers are spending increasing amounts on affiliate marketing, what impact these rapidly developing vertical search sites are having on buyer behaviour online, and what these changes mean for major Web companies, especially Google. But first, we will explain a little more about what affiliate marketing actually is.
