Form Validation - coldlamper - 04-06-2016
Won't this return true in the 3.0.6 release when it should return false?
$this->load->library('form_validation');
$inputData = ['inp' => []];
$this->form_validation->set_data($inputData);
$this->form_validation->set_rules('inp[]', 'Input field', 'required');
//Will return true
$this->form_validation->run();

It will return true, but that's what is supposed to happen - the 'required' rule in that case is applied on any elements that the input array may have.

Thanks for the answer.
So how would you require an array that has a least one value without being able to bypass it with an empty array?
RE: Form Validation - Narf - 04-06-2016
Something like this:
$this->form_validation->set_rules('inp', 'Foo', 'required');
$this->form_validation->set_rules('inp[]', 'Bar', 'required');
Though, I don't understand everybody's obsession with making their inputs arrays ...
If you want to receive an undefined count of inputs - you don't need to require at least one.
If one is mandatory and more are optional; then the first is not the same as the optional ones - use two separate inputs.
If you're trying to do 'user[name]' when 'user_name' works perfectly fine, then you're just doing it wrong.

Thumbs up. I have seen one too many forms with every input being 'form[user][first_name]' 'form[user][last_name]

I agree with not using arrays if you don't have to. My use case is selecting categories where the user must select 1 or more categories. There are many categories and they change quite frequently.
