PmWiki: Upload Variables

See also: Uploads, Uploads admin.

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).
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.
The url of the directory given by $UploadDir. By default, $UploadUrlFmt is derived from $PubDirUrl and $UploadDir.


The format of the upload link displayed when an attachment is present. No default is set.
The format of the upload link displayed when an attachment not present. Defaults to
      <a class='createlinktext' href='\$LinkUpload'>\$LinkText</a>
<a class='createlink' href='\$LinkUpload'> Δ</a>");
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.
    $UploadPrefixFmt = '/$Group/$Name';    # per-page attachments
    $UploadPrefixFmt = '';                 # sitewide attachments
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. Don't forget to protect your directory /uploads/ with a .htaccess file (Order Deny,Allow / Deny from all).
Set $EnableUploadGroupAuth = 1; to authenticate downloads with the group password. This could be used together with $EnableDirectDownload = 0;.
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.
When set to 1 (the default), determines if overwriting previously uploaded files is allowed.
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
$UploadNameChars = "-\\w. \\x80-\\xff"; # allow unicode
Overall size limit for groups, in the group configuration file (i.e., local/Group.php)
Overall size limit for all uploads.
   $UploadDirQuota = 100*1024;         # limit uploads to 100KiB
   $UploadDirQuota = 1000*1024;        # limit uploads to 1000KiB
   $UploadDirQuota = 1024*1024;        # limit uploads to 1MiB
   $UploadDirQuota = 25*1024*1024;     # limit uploads to 25MiB
   $UploadDirQuota = 2*1024*1024*1024; # limit uploads to 2GiB
Maximum size for uploading files, 50000 octets (bytes) by default.
