LinkPageExistsFmtTooltip

Question

How can I add a tooltip (small popup text that is displayed when you run with the mouse over a link) for a link to a existant page ?

Answer

Adding the target page title as a tooltip

Adding a tooltip using the title of the target wiki page is quite straightforward as demonstrated in LinkPageCreateFmtTooltip. Add to config.php:

Adding the target page description as a tooltip

A description can be added to a page using the (:description ...:) markup.
A title can be added to a page using the (:title...:) markup

To display a page's description as a tooltip instead of the title, use

To display a page's description, but fall back to the page's title if a description isn't set, use the following:

$FmtPV['$DescriptionT'] =
  '@$page["description"] ?  $page["description"] : PageVar($pn, "\$Title")';
$LinkPageExistsFmt = "<a class='wikilink' title='{\$DescriptionT}' href='\$LinkUrl'>\$LinkText</a>";

Adding an arbitrary text as a tooltip

Use links like [[target | text "tooltip"]]. The tooltip text needs to be inside the double quote marks.

Add to config.php

## [[target | text "tooltip"]]
Markup('[[|tt','<[[|',
  "/(?>\\[\\[([^|\\]]*)\\|\\s*)(.*?)\\s*(\"(.*?)\")?\\s*\\]\\]($SuffixPattern)/e",
  "Keep(ToolTipLink(\$pagename,PSS('$1'),PSS('$2'),PSS('$4'),'$5'),'L')");

function ToolTipLink($pagename, $tgt, $txt, $tooltip='', $suffix) {
  global $FmtV;
  $FmtV['$LinkAlt'] = $tooltip;
  return MakeLink($pagename, $tgt, $txt, $suffix);
}

$LinkPageExistsFmt = "<a class='wikilink' href='\$LinkUrl' rel='nofollow'
   title='\$LinkAlt'>\$LinkText</a>";
