[Resolved] passing value around

[leavehere]

Hi,

I am using, e.g. echo "...href=\"ok.php?id=$userid\"... to pass value, however I think this method is not secure, such as userid should not be displayed in URL. so my first question is: is there any way to encrypt the data?

I know there are some other methods such as using SESSION or using Hidden Form, however, when we retrieve data from mysql, for example, in a FOR loop, we make a link for each retrieved Username, and thus for each username, different value need to be passed through the link, e.g. ..ok.php?username=?username...

Thanks a lot!

You can always just use something like base64_encode() and base64_decode().
