RE: [PHP] Stopping Forms Being Submitted Twice or Not Complete[Scanned]

Vicky, You can use JavaScript to check that fields are complete but I'm not sure whether this will deal with the issue of duplicate entries. I often set some kind of identifier on the first form and set it in a hidden field ( using md5(uniqid(time())) ) to store in the table when the form is submitted. When subsequently saving the data you can then check on whether a record has already been created with this identifier and only save the record if this is not the case. I don't know whether this is the most elegant or efficient solution. Any further thoughts would be welcome!

And if there is what is it and where should I put it? I'm getting fedup with duplicate and blank entries filling my guestbook ;-)
