Add PHP code into CKEditor

[rpetges]

If the plugin does not offer to use a place holder in a page instead of a PHP call, the best way is to put the PHP call in a component mycomponent, install the DynPages and include the component in your page with {% mycomponent %}.

OK, I think I now better understand how GS works ... I'm really new in the CMS world (converting from RapidWeaver).

Just one question : What exactly is a place holder and how does it work / look alike ?

Many thanks for your help,
Romain
