The steps for getting the current Page objects are as follows:

Calling the static getCurrentPage function on the Page class will look in the concrete5 Request object to get the current page. If that is not set, concrete5 will use the global $c variable. Note the use of site_process.php to dump the current page variable. We used this file because it is read after concrete5 has set the current Page object. Using site_post.php would have resulted in a null object.

You may have already noticed that sometimes developers will use the global variable, $c, within their code to get the current Collection or Page object. This typically works fine, but best practices would be to use the getCurrentPage function to handle this for you.
