Select and Radio Checkbox groups

Selects

Selects can be created simply by creating a new instance of a Select and adding Options and/or Optgroups to it.

<?php

//Create the select element
$select = new Select();

//Add some regular options
$select[] = new Option('red');
$select[] = new Option('green');
$select[] = new Option('black');

//Create a new optgroup
$optGroup1 = new Optgroup();

//And add some options to it
$optGroup1[] = new Option('one');
$optGroup1[] = new Option('two');
$optGroup1[] = new Option('three');

//Add the group to the select
$select[] = $optGroup1;

The constructed Select can then be added to a form as normal.

Radio/Checkbox groups

RadioGroup

Radio buttons can be grouped by first adding them to a RadioGroup. Note that the name of the group is set after adding the Radios to the group. Setting the name of the group after assigning children will update all the contained Radios with the same name.

<?php
use Fuel\Fieldset\Input\RadioGroup;
use Fuel\Fieldset\Input\Radio;

$form = new Fuel\Fieldset\Form;

$group = new RadioGroup();
$group[] = new Radio('', array(), '1');
$group[] = new Radio('', array(), '0');

$group->setName('test');

$form[] = $group;

CheckboxGroup

These work much the same way as the RadioGroups except that the name defaults to an array. Setting a group name of foo will result in an input name of foo[]. This behaviour can be configured using the setAutoArray method from ToggleGroups.

<?php
use Fuel\Fieldset\Input\CheckboxGroup;
use Fuel\Fieldset\Input\Checkbox;

$form = new Fuel\Fieldset\Form;

$group = new CheckboxGroup();
$group[] = new Checkbox('', array(), '1');
$group[] = new Checkbox('', array(), '0');

$group->setName('test');

$form[] = $group;
