The SEO team requested we add Facebook Like buttons to all of the Promotion Pages on EverestPoker.fr.

The EverestPoker.fr site is built using Plone and the Promotions use a custom "promotion" content type

First step was to create a viewlet to contain the Facebook code

This code is designed to work in 15 different languages and contain a generic Partner ID (PID) that can be manually overwritten

Second step is to add the required meta tags to the head section of site found in the "main_template"

Third step is to register the viewlet in two files

Configure.zcml:

viewlets.xml

The last step is to add a custom field to the Promotion content type for the Partner ID. atapi.StringField( name='facebook_like_id', required=False, widget=atapi.StringWidget( label=_(u"Facebook Like Partner ID"), description=_(u"Adds a specific Partner ID to the like button"), ), )

Below are screen shots of what the final product would have looked like (wasn't released because of Facebook policy in regards to gambling sites).
