model validationRules for nullable fields? - lukmim - 01-14-2022 Is there a way of setting up model validation (for example "integer" or "numeric") for fields that are not required and also can be null? I'm aware of the "if_exist" (doesn't allow null values) and "permit_empty" (permits also some non-null invalid values) rules, and also I figured "callback_" probably can't be used for this (unless I recreate all needed validation rules with callbacks that would allow null, for example callback_nullableInteger, callback_nullableNumeric, callback_nullableAlphaNumeric etc) RE: model validationRules for nullable fields? - BilltheCat - 01-14-2022 You could always wrap your rules in normal PHP logic... I'm not sure what rules you could apply in this case, but this might be what you're looking for: PHP Code: $post = $this->request->getPost(); RE: model validationRules for nullable fields? - kenjis - 01-14-2022 It seems you are correct and there is no good way to do accept only null or integer.
