When I have a page whose name is a number, I sometimes use the Summary page text variable in pagelists as the page's effective title. To make the markup easier for users, I want to create custom markup similar to PmWiki's [[MyPage|+]] markup. My markup would use the tilde instead of a plus sign, to produce link text with the page's $:Summary, if available, and using the title, or if necessary the page name, if it's not.
Here's what I've written so far: if …. # I NEED A CONDITIONAL HERE that will evaluate to true if the to-be-saved Summary page text variable will be null $BestAvailableTitle = '$Titlespaced'; } else { $BestAvailableTitle = 'PageTextVar($pagename,"Summary")'; } $FmtPV['$BestAvailableTitle'] = $BestAvailableTitle; Markup('[[|~', '<[[|', "/(?>\\[\\[([^|\\]]+))\\|\\s*\\~\\s*]]/e", "Keep(MakeLink(\$pagename, PSS('$1'), PageVar(MakePageName(\$pagename,PSS('$1')), '\$BestAvailableTitle') ),'L')"); I have tried using for the missing conditional the following: function PTVlen ($page, $ptv) { $var=PageTextVar($page,$ptv); return strlen($var); } if (PTVlen($page,"Summary") == 0) { But when I do that, preview shows the old page text variable values when it previews the page. What do I need to do to make this work? Note also: I'm using "/e" in the markup. I think I read that that was deprecated in PHP 5.5. Although I'm not using that PHP version yet, I have no idea how to do this any other way. Suggestions are welcome.
