The main goal of the project is to create a plugin (that is separate from existing ones) for the Fremont Community Church website (the site has a main site and number of sub domains that are mostly blogs.). This plugin should allow each sub domain site to have a shared header and footer navigation. The plugin needs to be separate so that any updates to other plugins won't effect the functionality of this blog. The client provided the multi-site on CMS Wordpress on which each sub-site has its own content. Our task was to create the plugin that should set up the same footers and headers for all sub-sites. For this purpose we customized the function switch_to_blog(). The design of the plugin back end is very simple, so even unknowledgeable users can install it and use.
