Description: ------------ Class Rules needs and attribute (validateIfEmptyValue, by default false) that says to validate() execute that rule even when the element has an empty value. Now it is hardcoded for required and uploadedfile, in addRule(). These rules should set validateIfEmptyValue attribute to true. I need ( :) ) that when i created a rule called requiredIfCompare, where an elemento should be required only if some comparison of other elements results true. It could be in QF 3, next version ;~

I agree 100%. Much flexibility can be gained by allowing a way to lift the validation ban on not-required-and-empty fields. The aforementioned solution should work just fine without breaking anything.

Implemented in CVS. In QuickForm2 the rules themselves contain code to decide whether empty elements should be validated or not. Currently Length, Regex, MaxFileSize and MimeType rules do not try to validate empty fields and will return true for them, all other rules will validate. One can prevent validation of empty values by rule chaining, e.g.: $field->addRule('empty') ->or_($field->createRule('gt', 'Should be positive', 0));
