Custom php code in stacks, using session variables in stacks forms

Does anybody know how to include php code in stacks, for example to display session variables, and how to include session variables values into form fields ?

Many thanks in advance

there are a number of ways, but the simplest is to add an HTML stack and put your php in there. remember to rename the page with a “.php” extension so that your web server will process the php inside of it.

other ways:

Stacks works very much like other parts of RapidWeaver. A Text stack works just like a Styled Text page. If you want to add php to a Styled Text page (or Text stack) you can add the php, select it, and choose the menu option: Format > Ignore Formatting

HTML Stacks work just like HTML pages – and should except php too.

And Markdown Stacks and Markdown pages are really just accept all HTML too – so they’ll work with php too.
