Re: Avoiding user refresh of pages with forms

Is there a way to key off of the data inserted? Like some unique value or set of values that you can do a quick lookup before you insert/update/delete again... Or you could venture into an AJAX style of submission keyed off of a button click then a refresh to a 'report' page, in which case no POST variables are actually passed to the report page, so refreshing it will just present the same data... -Brad Jeff wrote:

To follow on from what Brad said - would it be possible to generate a "key" as a hidden value when the form is created. The first time the user submits the server checks if that unique code has ever been used within the current session - if not, adds value. If so, ignores. As a "unique" key you could use say timestamp plus random number. HTH Rory
