I would double check your sequence of events because it seems like something is off.

It sounds like you’re processing the post data, then returning an HTTP response rather than a redirect. When your user refreshes the page they resend the POST data.

I’m wondering where and when are you processing the POST data and if you’re correctly redirecting.

The page that the form submits to should process the POST data and create an entry (sounds like that is working).

If you want to avoid having the double post issue on a successful submission it’s best to redirect to another page AFTER you’ve processed the data and successfully saved.

This will not pass the POST data to the new view, and the user can refresh the page to their hearts content without having to worry about double submissions.
