Accessing and changing content when a page is saved

[jamalrob]

I couldn't get that to work, but I'm not too worried: as I say, I've got the plugin running when the pages are displayed, like so...

Code:

add_filter('content','html_from_textile');

# functions
function html_from_textile($content) {
    $textile = new Textile;
    $html = $textile->TextileThis(stripslashes($content));
    return $html;
}

...which works fine.

I'll need to learn more about how GetSimple is putting things together to get it working the other way.
