When do you want the form to post itself? When all of the fields are
completed? You could add a Javascript onblur function to all of the fields,
which will fire document.form.submit() if all the fields are filled.

This example will work with text and hidden fields.

<input type="text" name="myField" onblur="sCheck()" />

function checkfields(){
 elms=document.myForm.elements;
 for(ff=0;ff<elms.length;ff++){
  if(elms[ff].value==""){return false;}
 }
 return true; // only fires if all fields have a value
}

 function sCheck(){
  if(checkfields){document.myForm.submit();}}
