Support array form value by Validator

[tanakahisateru]

Pinoco's validator framework can't deal array form value. But there are even enough amount of them like multiple check-box or such as.

<label><input name="opts[]" type="checkbox" value="opt1"/>GPL</label>
<label><input name="opts[]" type="checkbox" value="opt2"/>BSD</label>
<label><input name="opts[]" type="checkbox" value="opt3"/>MIT</label>
<label><input name="opts[]" type="checkbox" value="opt4"/>Apache</label>

My idea:

<?php
$validator->check('opts')->is('array')->all('in opt1,opt3,opt3,opt4');

<?php
$validator->check('opts')->is('array')->any('in opt1,opt3,opt3,opt4');
