I tested this php form, and it worked on 2 out of three computers, all of which were on different networks. The one that didn't work stalled after I hit submit . . . all I got was a blank page . . . no error messages or anything. This happened whether it was on a PC or Mac, in Firefox, or IE. Any ideas what could be causing it? Thanks. <?php $domainname = "mydomain.com"; /** Change this to your own domain **/ $adminmail = "info@mydomain.com"; /** Change this to your own email address **/ $webmail = "https://mydomain.com/mail/"; /** Change this to your own webmail url **/ $scriptlocation = "/home/ecreate"; /** Change this to point to your script **/ $name = escapeshellcmd($_REQUEST['name']); $username = escapeshellarg(escapeshellcmd($_REQUEST['username'])); $password = escapeshellarg(escapeshellcmd($_REQUEST['password'])); if (!isset($_REQUEST['name'])) { ?> <html> <head> <title></title> </head> <body> <form method="post" action="index2.php"> Full Name: <input type="text" name="name" /> <br> Username: <input type="text" name="username" /> <br> Password: <input type="password" name="password" /> <input type="submit" /> </form> </body> </html> <?php } elseif (empty($name) || empty($username) || empty($password)) { ?> <html> <head></head> <body> <span style="color: rgb(204, 0, 0);">Error:<br> </div> You have left one of the information fields blank.
