An enhancement to the current upload feature to allow the deletion of uploaded files.

This cookbook entry creates a new markup (:newattachlist:) which includes a delete link for each file listed. The user needs to have upload permission to see the link and the associated action delattach requires upload permission as well.

If you want to replace the standard list PmWiki uses for the upload action you have to edit the page Site.UploadQuickReference and replace (:attachlist:) with (:newattachlist:).

This is my first PmWiki extension and I am still learning how to properly write those enhancements. Feedback is highly encouraged so I can learn.

I don't want to forget to mention that the base code for this script was taken from the standard upload.php script. Maybe down the road this could be integrated with the core upload.php script.


Copy the attachdel.php to your cookbook folder. Add the line include_once('cookbook/attachdel.php'); to your local/config.php file
