OK, so I'm wanting to calculate values for a few fields when a SQLFORM record update is accepted. My understanding is that I should use onvalidation = calculation_function but I'm finding that within my onvalidation function form.vars does not include the id field which I need to know in order to do the other db lookups necessary for my calculations. Why is the id field missing from the form var that onvalidation passes it to my function? Is this some sort of security/data integrity thing to prevent me from foolishly changing it? What's the appropriate way to pass the record's ID to my onvalidation function?
