I now have it working. Here's what I did:
1] Put this markup in config.php:
Markup('^trail:', 'directives',
'/^trail:(.*)/e',
"\$GLOBALS['TrailSource']='$1'");
2] In your template PHP file add a function:
function ShowTrail() {
if ($GLOBALS['TrailSource']!=""){
echo MarkupToHTML($pagename,"<<|[[".$GLOBALS['TrailSource']."]]|>>");
}
}
3] In your template TMPL file add the following wherever you want the
trail to appear:
<!--function:ShowTrail-->
* I'd like to know how to refer to $GLOBALS direct from the .tmpl file.
Is it possible?
* Is this a reasonable way to achieve my original goal of having a user
defined variable displayed in more than one place on a page?
It took forever to work that out, despite frequent hints from PM. I'd
like to document this in a generic way (how to display page variables on
your wiki). What's the appropriate place to put this info?
