shocker-z Posted March 1, 2006 Share Posted March 1, 2006 Only way to do it without refreshing using PHP would be to have litle iFrams and then each box is in a diffrent page and the submit uses the ifram target window to post too and then the last one actualy targets the main page instead of frame.. i havn't done this myself tho so not 100% on it. Only way without refreshing the page will be javascript or some other clientside language as PHP is parsed serverside. Quote Link to comment Share on other sites More sharing options...
