Accessing the Data items
I am new to Gossamer, have about 6mos perl exp. I want to be able to grab a field (which is a ftp url) when submitted in a links db, and go to that url to get the files size and use that as the fields value. While I can do the code ncessary to do this in Perl, where and how can I easily grab the field after it's submitted from the add in the Links Administrator??? I have 14 fields in the db and the one I am after is #13. So regardless of what the user puts in the form , I want to validate it.....

Any help is mucha appreciated..

I'm trying to do something similar, with image sizes. I want to upload an image, and have it grab the dimensions and insert them into the database.
