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
set_field_init(
)
function.
Similarly, the function
field_term(
)
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.
The

The
form_term(
)
function will return a pointer to the function that will be called
just after the form is unposted from the screen, this function may be
set by using the
