Checking for variable set

[marcebra]

Hello,

I have a form in my webpage that requires that a variable be sent to the form in order for it to read from a variable "stuff" pertaining to that variable. The only problem is that one can just type in the url with out the "?name=blah" as a sufix and still see the page (but without any information from the database).

How can I stop people in their tracks? I tried a code in the beginning of the page "if ($name == "")" then "meta refresh" to the home page. But the problem is that the entire page loads before forwarding (even though the refresh script is the first line of code -- before "html").

I would appreciate it if anyone can give me a script to use.

Thanks in advance

You can use something like this:

if(!isset($_GET['name'])|| ($_GET['name'] == "") )
{
header("Location: http://accessdeniedpagehere.com");
}
