keep <Select> values when page refreshes

I am currently building a form and one field requires grabbing values from a database to show the result.  Thus I need to refresh the page passing the values that have are ready been entered in the address bar.  For example: webpagename.php?fname=Joe.  Therefore when the page refreshes, the name Joe will remain in the first name text box.

I would like to the same with values in a combo box (<Select><option></option></Select>) .  The combo box gets dynamically generate when the user adds an item.  What is the best way to retain the added values when the page refreshes.
