Re: Not Allowing REload or REfresh with this script?

try this, your code example has some design flaws. <?php include_once('session.egn'); if (isset($HTTP_POST_VARS['submit'])) if ( isset($HTTP_SESSION_VARS['done']) AND $HTTP_SESSION_VARS['done'] == $PHP_SELF) { echo "a <br>\n"; echo "You can only press submit once <br>\n"; exit(); } else { echo "b <br>\n"; $done = $PHP_SELF; session_register('done'); } // do some code echo " <form method='post' action='$PHP_SELF'> <input type='hidden' name='submit' value ='1'> <input type='submit'> </form> "; ?> im not exactly sure on what if (issset($userfile)) { global $userfile; unset($userfile); } else { // do some code } this is supposed todo, what is the global there for? what does it do? please explain. -- Chris Lee Mediawaveonline.com ph. 250.377.1095 ph. 250.376.2690 fx. 250.554.1120 lee@mediawaveonline.com "Dhaval Desai" <dhaval_adams@yahoo.com> wrote in message news:20010306084242.61687.qmail@web10014.mail.yahoo.com... Hi! Well I need help with something. I have a form which has a ction to a file called actio.php Now When I hit the submit button. It goes to the file and it performs a certain action as seen below: action.php: is as follows: <?php if(isset($userfile)) { echo "$userfile is set"; global $userfile; unset ($userfile); } else { echo "Sorry buddy , Userfile is not set"; } ?> My main intentyion is to unset the variable so that When the page is REFRESHED or RELOADED. It should execute the else code block. I am trying to implement it on one of my websites where users can not refresh a particular a page.
