[Mapserver-users] Query template - Extract: Layer Class Name

[Martin, Daniel A]

Well, I'm not quite sure.  I don't know of a built-in variable.  I guess I would want to know how your user reaches this query page.  If it is from a link/submit from a prior page that DOES have a legend, I would pass the item name as a custom variable.

For instance, I use a custom variable called "title" that I pass between every map as a hidden element of the map form.  I can reference this variable in my template simply as [title] because MapServer is smart enough to pull it from the querystring.  I place it in my <title> tag in the header, and output it on the template.
