The Facebook “Like” is an important Social Media Marketing tool. It instills customer confidence and enables new marketing opportunities. Increasing the number of likes your e-Commerce site has can sometimes be difficult but one way to really boost those likes is to offer a reward in the form of a discount code if customers like your Facebook page. This application interfaces with your Magento Store and runs as a Facebook Tab Application to create configurable dynamic dicount codes for Facebook users who like your page.

I wanted to accomplish this with a standalone PHP application embedded into a Facebook page tab. The goals were to step the customer through connecting with the Facebook application, liking the page and generating / managing the discount codes and Magento coupons.

We want to take full advantage of the marketing information we can glean from Facebook so another requirement was so store the customers Facebook profile information in a database along with the generated discount code.

We can also generate a wall post on the customers Facebook wall to ensure our offer is shared with their Facebook friends.

This PHP application uses the Facebook API to communicate with Facebook and loads Magento externally to generate the Magento coupon sales rules dynamically.

This is really a proof of concept, the way you would actually implement this offer depends on how many current likes your Facebook page has, do you want to offer a coupon code for existing users who have already liked the page? This could get costly if you already have thousands of likes. Think about how you will implement the coupon, perhaps you will offer a discount for a total spend over a certain amount.

Comments for improvement and development are welcome.

• PHP5.x/MYSQL

• Public webspace on the same server as your Magento installation

• A valid configured Facebook Tab application.

• Magento 1.3+

Copy files to your hosting website. Facebook applications require both http and https connectivity to the application url. If you do not have an SSL certificate configured for your site some Facebook users will not be able to access the application.

Create a new MySQL database and add the following table

 CREATE  TABLE  `MYDATABASE`.`users` (  `id` int( 6  )  NOT  NULL  AUTO_INCREMENT ,
`couponCode` varchar( 64  )  COLLATE utf8_bin NOT  NULL ,
`appwallpost` tinyint( 1  )  NOT  NULL DEFAULT  '0',
`fbid` varchar( 64  )  COLLATE utf8_bin NOT  NULL ,
`name` varchar( 64  )  COLLATE utf8_bin NOT  NULL ,
`first_name` varchar( 64  )  COLLATE utf8_bin NOT  NULL ,
`last_name` varchar( 64  )  COLLATE utf8_bin NOT  NULL ,
`link` varchar( 128  )  COLLATE utf8_bin NOT  NULL ,
`image` varchar( 128  )  COLLATE utf8_bin NOT  NULL ,
`gender` varchar( 32  )  COLLATE utf8_bin NOT  NULL ,
`locale` varchar( 12  )  COLLATE utf8_bin NOT  NULL ,
`timeStamp` timestamp NOT  NULL  DEFAULT CURRENT_TIMESTAMP  ON  UPDATE  	CURRENT_TIMESTAMP ,
PRIMARY  KEY (  `id`  ) ,
UNIQUE  KEY  `fbid` (  `fbid`  ) ,
UNIQUE  KEY  `couponCode` (  `couponCode`  )  ) ENGINE  = InnoDB  DEFAULT CHARSET  = utf8 	COLLATE  = utf8_bin

Create a new Facebook application/page tab application and configure the canvas URLs to point to your hosted application files.

Add the application to a Facebook page tab if required.

Configure the App by editing - config/applicationConfig.php configure application and coupon options create application images and upload to /images folder - see demo images for details

Configure your App Credentials by editing - config/applicationCredentials.php configure database credentials configure facebook application credentials

Test the application.
