javascript runs client-side, php server-side.
After the document is delivered, there is no connection between the client and the server. Neither can php access the clients HTML-DOM nor javascript php's variables and functions.
There has to be a new request to the server to transmit data back and forth.
I suggest setting the values of the form and then submitting it in the javascript-function.
