Much thanks for the plugin. I have a few problems though. I have set in the back end for 5 file attachments but am only allowed to upload a single file on the form. Also every time I save changes for the plugin settings in the admin the PDF Base File adds multiple back slashes to the url so I end up with something like this (C:\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\). How do I fix these bugs? Thanks in advance.
For the multiple slashes, you would need to add stripslashes() around the echo of the textarea(s) on the admin form, then resave with the correct path.
Off hand, I’m not sure why you are only allowed to upload one attachment.
