Extending Validation class to call a method that returns a modified value |
[eluser]housecor[/eluser]
I understand how to extend CI's validation class to add additional methods that return bool, but how do I create method that modifies the value being validated? For example, you can call native PHP functions in your validation like this: "required|strtoupper" I'd like to extend the validation class so I can call blank_to_null as part of my validation so any fields posted blank are converted to null before db insertion. Anyone have an example of how to pull that off?

I extend the form_validation class instead of callbacks so I can use the functions on more than one controller. It would be nice if these functions had the same features. Is that possible?

Odd. Looking at the code in the _execute method, it does check for non-bool return values, on callbacks, internal PHP functions, and form_validation methods... Code: $this->_field_data[$row['field']]['postdata'] = (is_bool($result)) ? $postdata : $result; |
