<<|[[PmWiki.Variables]]|>> :$EnableUpload:The upload.php script is automatically included from stdconfig.php if the $EnableUpload variable is true in config.php. Note that one may still need to set an upload password before users can upload (see [[UploadsAdmin]]). :$UploadDir:The directory where uploads are to be stored. Defaults to ''uploads/'' in the pmwiki directory, but can be set to any location on the server. This directory must be writable by the webserver process if uploading is to occur. :$UploadUrlFmt:The url of the directory given by $UploadDir. $IMapLinkFmt['Attach:'] ->The format of the upload link displayed when an attachment is present. No default is set. :$LinkUploadCreateFmt: The format of the upload link displayed when an attachment not present. Defaults to \$LinkText\\  Δ"); :$UploadPrefixFmt:Sets the prefix for uploaded files to allow attachments to be organized other than by groups. Defaults to [@'/$Group'@] (uploads are organized per-group), but can be set to other values for sitewide or per-page attachments. $UploadPrefixFmt = '/$FullName'; # per-page attachments $UploadPrefixFmt = ''; # sitewide attachments :$EnableDirectDownload:When set to 1 (the default), links to attachments bypass PmWiki and come directly from the webserver. Setting $EnableDirectDownload=0; causes requests for attachments to be obtained via [@?action=download@]. This allows PmWiki to protect attachments using a page's read permissions, but also increases the load on the server. :$EnableUploadVersions:When set to 1 (default is 0), uploading a file to a location where a file of the same name already exists causes the old version to be renamed to @@file.ext,timestamp@@ (instead of being overwritten). @@timestamp@@ is a Unix-style timestamp. :$UploadNameChars:The set of characters allowed in upload names. Defaults to [@"-\w. "@], which means alphanumerics, hyphens, underscores, dots, and spaces can be used in upload names, and everything else will be stripped. $UploadNameChars = "-\w. !=+"; # allow exclamations, equals, and plus :$UploadMaxSize:Maximum size for uploading files (50000 octets by default)
