Opening new browser window

I would like to open a new browser window from within my php script (edit.php), a window in which another php page is run (search.php). search.php should be able to receive $_POST vars etc. from edit.php. I am not sure that the javascript solution to popup a window is correct, because then the popup does not behave normally. By normally, I mean that when I use javascript to popup a new window (search.php), and in search.php I have a form <form action="searchAction.php" method=post> <input type=hidden name=caller value=window.opener.location.href> <input type=hidden name=ID value=<? $_GET['ID'] ?> > <input type=hidden name=Type value=<? $type?> > <input type=button name=btnOK value=OK> <input type=button name=btnCancel value=Cancel> </form> clicking OK or Cancel does absolutely nothing. So, I would like to avoid javascript and simply open a new browser window to run search.php. What is the accepted way to do this in php? tia, Rich
