If page is refreshed data is written twice to database

I have an HTML form that gets user info and when they press the submit button it will add the data to the database and then display the information they just added.  When the user is on the confirm page, if he pushes refresh it will resubmit the data to the database.  I cannot check to see if the row already exists, because it is okay for there to be multiple rows that are the same (just with a different time stamp).  What is the best way to prevent this from happening?  Thanks!

and your form be like this:
<form name="inputform">
<input type="text" name="field1" value="" onblur="javascript:validate();" />
<input type="text" name="field2" value="" onblur="javascript:validate();" />
<input type="submit" name="submit" value="Submit" disabled
onclick="javascript:disable();" />

Open in new window

After adding data redirect the page to same page, it will reload the same page. And refreshing will not add data again.

Hope this helps.
