Store Locator Plus®
In 2011 Cyber Sprocket Labs was in the midst of porting a website for Tommy Hilfiger from a proprietary platform to WordPress. One of the pieces of technology on the prior site was their store locator platform. During the porting process I took on some of the responsibilities of crafting the locator plugin in WordPress.
The code is fully documented with phpDoc style comments. All code written in the past 18 months adheres, as closely as possible, to the WordPress PHP Coding Standards.
You can find the source code for the main Store Locator Plus® plugin on Bitbucket.
