PreventUploadOverwrites

Goal

Prevent users from being able to overwrite existing attachments/uploads.

Solution

Add the following code to local.php:

  $EnableUploadOverwrite = 0;

Discussion

By default, the PmWiki.Uploads feature allows authorized users to overwrite existing attachments. For some applications this is inappropriate, especially since the upload/attachment feature doesn't have an easy mechanism for recovering previous versions of an attachment. Setting $EnableUploadOverwrite to zero tells the upload.php module to not allow existing files to be overwritten.
