Passing vars through link security?


Recommended Posts

Hi, I read somewhere that when passing a variable through a link it makes the site insecure. Is this true, if it is how do I make it secure?


Also, can people list other security breaches that a newbie should know and the fixes please.

what they mean is that when you're passing varibles through a link, the user can see your varibles. So if you had www.foo.com/index.php?username=bob&password=test, users would be able to see the varibles and their values. If you use a POST method instead of GET (<form action="?" method="post">), your varibles are "hidden" and do not appear in the link
