Creating a page footer

1. Copy View element file from app/Plugin/CakeTheme/View/Elements/footerPage.ctp.default to app/View/Elements/footerPage.ctp (if needed).
2. Edit element file See Example of footer

3. Define next valiable in method beforeFilter your AppController, e.g.:

   /**
    * Called before the controller action. You can use this method to configure and customize components
    * or perform logic that needs to happen before each controller action.
    *
    * Actions:
    *  - Set global variables for View.
    *
    * @return void
    * @link http://book.cakephp.org/2.0/en/controllers.html#request-life-cycle-callbacks
    */
   public function beforeFilter() {
       // If `true`, show footer
       $showFooter = true;
   
       // Version of project
       $projectVersion = '';
   
       // Project author
       $projectAuthor = '';
   
       $this->set(compact(
           'showFooter',
           'projectVersion',
           'projectAuthor'
       ));
   }
