Associative arrays not handled correctly about forms

[milo]

Could you please elaborate a little bit?

I created a select input with the following array:

$data = ['a_1' => 'Test', 'a_2' => 'Test2'];

Using the Form::IS_IN rule with this $data array as filter won't work as it's testing against it's values and not the keys. In this case array_keys would be enough, but if optgroups are used one does need to flatten all keys out to get all the keys to test against.

Why are you adding this rule?

Anyway, this is correct behavior.

I'm adding the rule, because I want to make sure nobody has altered the select options to submit an invalid value.

@LostKobrakai That's already built-in feature of SelectBox control, you don't need to do that.
