BreadCrumbTrail

Question

How can I add a "bread crumb trail" to my pages?

Answer

First, define a variable called $BreadCrumbFmt that contains what you want output for the trail:

    
    $BreadCrumbFmt = "<span class='breadcrumb'>
      <a href='\$ScriptUrl'>Home</a> :
      <a href='\$ScriptUrl/\$Group'>\$Groupspaced</a> :
      \$Titlespaced </span>";
    

Then, simply add the variable $BreadCrumbFmt into your layout template file at the point where you want the trail to be displayed. The above example would display as

$Breadcrumb?

Note that in this approach it's possible to have specialized per-group or per-page bread crumb trails by setting different values for $BreadCrumbFmt in PerGroupCustomizations.

If you want to provide a bread crumb markup that authors can place into a wiki page to display a bread crumb trail, you can also add something similar to the following:

    
    $DoubleBrackets['[[$Breadcrumb]]'] = 
      Keep(FmtPageName($BreadCrumbFmt,$pagename));
    

Notes

Comments

• Is there any way using this method to have a greater number of structure levels than permitted by group/page? Am I right in thinking that PmWiki does not allow for subgroups? Do I need to use Trail2Menu?
  • Ok, I think I have (partly) answered my own questions: Trail2Menu will do what I need. Only problem is I am using version 2.08, and I don't think Trail2Menu has been updated yet...
