Just to re-cap where they come from: It depends on how the data is being sent to your script. For example, variables passed on the query string - i.e.: http://www.site.com/file.php?a=hello&b=world Those variables (a and b) will only be visible via $_GET. Where-as values passed from a form that uses the POST method: <form action="file.php" method="post"> </form> These will only be available in $_POST.

If you're trying to pass values to a script that is expecting them to be in $_GET then you have to pass those values on the query string. What situation do you have that makes you ask this question? Perhaps with a little more detail we can explain further? -- Best regards, Richard Davey http://www.phpcommunity.org/wiki/296.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
