Jeff is right; phpMyAdmin is great, and I use it myself, but it's not at all what I need--I just want users to be able to easily input records into the database via a simple web front-end, and do simple searches.
After spending more time trying to get things installed, I like DaDaBik for its simplicity, but it may be a bit too simple--I'm begining to think relational-ness would be a major plus, and it doesn't offer any protection of data as-is--anybody can add or delete records. Perhaps with some hacking it'll do what I want, though... but at that point, I wonder if rolling my own wouldn't be almost as easy, which I'd really rather not do.
MOT sounds closer to what I'm wishing for, but I can't seem to get it inistalled on DH after an hour or so of fiddling. Is there a way to run PHP as CGI and turn off magic_quotes_gpc at the same time, without building my own PHP? I can get one or the other to happen via .htaccess, but not both.
