Writing Cookies

[BioSX]

Hi

 

I have 5 groups of radio buttons (6 radio buttons each, 30 radio buttons total). I am sending the value of these elements back to the same page using method=POST. What I want to do is write a cookie for each option selected, when the page reloads. I am a cookie noobie.

 

while(list($key, $value) = each($HTTP_POST_VARS))

{

WRITE COOKIE HERE in session using $key and $value <<<<<<<<<<<<<<

}

 

Basically I just need to know how to set and read the cookies, I am capable of handling the forms and other scripts to check the appropriate radio buttons on page reload.

 

Any help appreciated.
