====== Iframes ======
Every WLC site should have a page called "Iframe" with an "Iframe" page template.
A page with this template cannot be deleted by anyone but the superusers
These are known addresses of iframe pages:

  * https://www.welovecycling.com/wide/iframe/
  * https://www.welovecycling.com/fr/iframe/
  * https://www.welovecycling.com/dk/iframe/
  * https://www.welovecycling.com/sk/iframe/
  * https://www.welovecycling.com/pl/iframe/
  * https://www.welovecycling.com/es/iframe/
  * https://www.welovecycling.com/it/iframe/

===== Using the iframe page =====
To call an action on an iframe page simply pass a GET argument called //action//.
e.g.:
Showing a personality test
https://www.welovecycling.com/wide/iframe/?action=personality_test



==== Modifying the iframe page ====
By default the page has no header and footer, you can include these by passing GET arguments
  * **includeHeader=true**
  * **includeFooter=true**
i.e.: https://www.welovecycling.com/wide/iframe/?action=personality_test&includeHeader=true&includeFooter=true

===== Development information =====
The iframe page shows content based on registered action.
As a security measure it is not possible to call just any wordpress action.

==== Register actions ====
To register actions for an iframe page you can use a wordpress action hook //register_iframe_action//. The action receives two arguments, first is the name of the action, second is a callback. You can register multiple callbacks to the same action and they will be executed consecutively (no priorities, first in - first out)
