field_init
() function returns a pointer to the
function that will be called just after the current field changes and just
before the form is posted, this function may be set by using the

() function. Similarly, the function

() will return a pointer to the function
that will be called just before the current field changes and just after the
form is unposted, this function pointer may be set by using the
