Thanks Jason... your suggestions and the guide helped me to get this to work.
One other nag... how do I limit the filetype (extension) that can be uploaded i.e., I want to allow only PDF files to be uploaded and no other extensions?
The form works PERFECTLY on localhost. However, I've posted the webpage and uploaded the webassist folder to the production server but I'm surprised to get back a 500 error. I've checked the connection script (OK), checked for PHP errors in Dreamweaver (none found), checked the form for bad HTML or script errors (all OK) but still get a blank page. Permissions for the webassist folder and the upload webpage on the production server are OK. The MySQL database fields match the form's fields. So as far as I can find, all's well with the code and the build.
Didn't have this problem with two other websites I've built using Data Bridge so I'm sure I'm missing something obvious. Any ideas what other obvious areas I might check? (I'm including the page code in the Private Message.)
