(If you are using the form, you can skip this part. If you aren't, or don't know what I mean, read on!) For example: This code (page1.php): <?php $_GET['myvalue'] = 'This is MY GET VALUE!!!!'; $_POST['myvalue'] = 'This is MY POST VALUE!!!!'; ?> With this code (page2.php): <?php echo $_GET['myvalue']; echo $_POST['myvalue']; ?> Will not return an error, but the second page won't echo anything. However, if you access page2.php with the URL like this: http://localhost/page2.php?myvalue=This is MY GET VALUE!!!! The first line will output: "This is MY GET VALUE!!!!" To get the second line to work, you will need to use this: (page1.php) <form action="page2.php" method="post"> <input type="hidden" value="This is MY POST VALUE!!!!"> <input type="submit"> </form> When the button is clicked, page2.php, which is the same as before, will load, and the second line will cause the output of "This is MY POST VALUE!!!!". You can make both lines of page2.php work by changing the action attribute of the form to "page2.php?myvalue=This is MY GET VALUE!!!!". That way, they will both work. */ > Do I have to use session_start() ? /* This would be better. You can use sessions the way I think you are trying to use $_GET and $_POST. Just start the session on the first page, and set an element in $_SESSION and on the next page you can start the session again and read the value out of the array. Like this: (page1.php) <?php session_start(); $_SESSION['test'] = 'test value'; ?> (page2.php) <?php session_start(); echo $_SESSION['test']; ?> The page, page2.php, will show "test value" if you run page1.php first. $_SESSION is probably the easiest of all the superglobals to use. Try those, and if I'm completely off-base, and not even helping, try posting some code, which is ALWAYS a good thing to do. A big post asking for help never hurt anyone. Most people almost never read the short ones. Happy coding!!! */ -- disguised.jedi@xxxxxxxxx PHP rocks! "Knowledge is Power. Power Corrupts.
