Pass hidden data to page?

[atjong]

I\'ve read the thread with subject \'variable\' in which is advised to place a variable in the url making it available to the next page like this:

echo \"<a href=\'/nextpage?vaname=$varvalue\'>Link</a>\";

But this always shows the varvalue in the url of the page that is opened, for example:

http://www.mydomain.com/showcompany.php?id=123

Is there any way to keep this info (id=123) hidden for the user? This looks something like the difference between POST and GET in a form.

also if you use post, advanced users can find
the information you are sending via URL. so
my tip: dont send secret informations this
way. as far as i know there is no way to
hide parameters, when you are using href ...
post only works with forms

try to use session as this is one of the most secure way to know about the user . this way you will be having all the variables about that particular user with that session ID

you can also encode the values and when u use them u can decode them
