easy things - forms, variable sending

Hi, This is a trivial question - what function can I use to automatically proceed to some link, one that can be executed without any user input. How can we, most efficiently, send all the data (variables) from one page to another? Also, would you happen to know, as PHP is very often used in forms, how to generate a radiobutton, which when clicked upon automatically proceeds and does not need a Submit button? ~~~~~~~~~~~~~~~~~~~~ Krzysztof Piotr Wozniak ~~~~~~~~~~~~~~~~~~~~ Cell: (001) 617 - 493 - 2294 ~~~~~~ Room: (001) 617 - 970 - 1359 485 Dunster Mail Center ~~~~~ 02138 Cambridge, MA, USA ~~~~~~~ <http://www.fas.harvard.edu/~kwozniak> www.fas.harvard.edu/~kwozniak ~~~~~~~ One Ring to rule them all, One Ring to find them, One Ring to bring them all and in the darkness bind them
