I've badly make security part so only registered people ($_session['USER'] <- which is set after check Login/pass form) can access different zones but my problem is on refreshing page that contains action i.e. http://www.mypage.com?index.php&zone=contact&action=newcontact&name=geor ge only registered/valid users can make this zone code runs my pseudocode basicly works this way: function contactzone (no params) get URL parameters (like $action=$_get['action'] <some code> switch ($action) case 'new' $html.= show form (on submit set action to 'newcontact' break; case 'newcontact' Insert on database On success -> $html Default Show simple $html } <some code> return $html My problem is on refresh or back events on navigator; the action will execute again. How do I prevent that? Session variables? Check a single table storing used hashes sent by form (generated with md5 or any) on all forms containing actions event for all tables? What do you think?
