I don't know if this is any use, but the code on the submit page, here at PHP Builder, is nice. This is the kind of thing you want to do, right.
If you have a look at the code, you should be able to cut out all of the tools and paste them into your code. It will take some tweeking, but you should end up with something like what you want.
One thing I would do is have a search on the old net for some Javascript button tute's which will allow you to do whay you want.
http://www.javascriptsearch.com/ sounds like the place to start.
I have a similar project, where the kids at the school in which I work, want to upload the reviews that they do, onto their website. I created a table, reviews, and added the following fields, ID, Title, Review, Submitter, Date, Approved, ApprovedDate.
The review is stored in a text field. everything else is either tinetext or date.
I'm looking a a script that will allow them to enter the review on one form, and click one button to submit. The article will then be displayed for them and, once checked, another click uploads into the database.
The review then needs approving before it is live.
Hope this helps.
