You can't send the data to <input> fields, you have to send it to the php whatever script directly, using preferably POST.

code:

---

var http = new ActiveXObject("Microsoft.XMLHTTP");
http.open ("POST", postaddress, true);
http.send (postdata);

---

Something like that.

Securing it, could only be done by using SSL, but you need a server that can handle SSL traffic.
