I would like to store in db info bout changing the state of checkbox, (both check / unchecked).
This means that after changing checkbox value in record form, an action have to
be executed in before update event. If checkbox is left as it was, no action is
done
Anybody has an idea?
I think about storing present checkbox field value in variable in 'before show'
event, and then in 'before update' compare it with... with what?..
(kind of solution could be using 'after insert' event: sql query can look for
checkbox value in db after updating, and then comparing it with stored
variable.. but I'm lookin for much simple way)

Tomasz,
to compare the old and new values of checkbox field use BeforeUpdate event. The new value is stored in fld+field_name variable, to get the old one use dLookUp function. E.g.:
old = dLookUp("table_name", "field_name", "primary_key_field=" & pPKprimary_key_field)
new = fldfield_name

Nicole,
I've tried this with no effect.
Table 'users', db field 'blocked', PK 'user_id', dlookup in open event:
$old_blocked = dlookup("users", "blocked", "user_id=".get_param("user_id"));
and in before update the following:
if ($fldblocked != $old_blocked)
{
$db->query("UPDATE timestamp SET users_blocked = NOW()");
}
and the result is: 'timestamp' table is updated with NO condition, every time.

Tomasz,
I assume user_id field is added to record form. Is it primary key of the table used on this record form?

Nicole,
Yes, user_id is primary key for 'users' table and is added to record form

Try to print the $old_blocked and $fldblocked variables in BeforeUpdate event and check their values.

Nicole,
Thank you for patience.
After hundreds of mouse clicks, I've found it: data type in checkbox properties was 'text'. After changing to 'number', it worked. And finally, dlookup is in 'before update' event.
