Project: Donation Microsite
Date: November 2010
SZD (Shottenstein Zox & Dunn) requested a very simple microsite that would present users with a list of available organizations that they could choose to donate a dollar to (via SZD). They also requested that users only be given the ability to submit one donation.
The time frame for this was only a day, so I created a very lightweight site that had simple roll-over states for each organization which would present a detailed view of the organization to the user. Once clicked, the user would be take to a detailed thank you page for that organization and their donation would be recorded to a database.
To avoid more than one submission by users, created a cookie upon the user submitting their donation. If the user attempted to navigate back to the homepage it would take them to the detailed thank you page, thus preventing them from submitting another donation. If the user had their cookies turned off, also created a session ID upon submission that performed the same function.
