On page http://www.pmwiki.org/wiki/PmWiki/UploadVariables
the following variables are defined $UploadUrlFmt $UploadDir $UploadPrefixFmt But they are not exposed to PmWiki markup, i.e. don't work on the website. Are there any variables that are? On a second note (for NZTopo), can someone suggest some exemplar code that would left me validate, in a recipe, that a supplied filename (as a parameter) exists in a upload directory. It would have to cope with per page/per group attachments, and the standard pmwiki variants filename.ext group.page/filename.ext etc. Ideally if the file does not exist it would exhibit an upload link. Or is there an internal PmWiki function for the use of recipe writers? tia Simon
