创建具有相同名称（ZF3）的zend表单元素数组？

Question

Since i've to position checkboxes in design I'm not using MultiCheckbox and using Checkbox instead in zend. I've seen some zf1 solutions but didnt found any zf2 or zf3 solutions.

My Php Code

$languages = new \Zend\Form\Element\Checkbox('languages[]');
$languages->setLabel('English');
$languages->setValue('1');

This produce the following output

<?php 
    echo $this->formRow($form->get('languages[]')); 
    //It produce the following
?>
<input type="checkbox" name="languages[]" value="1" checked="checked">

How can I add more items with name "languages[]" without writing direct HTML code ?

Answer 1

You can use a Form collection for this:

1) In your form:

use Zend\Form\Element\Collection;

...

$languages = new \Zend\Form\Element\Checkbox();
$languages->setLabel('English');
$languages->setValue('1');
$languages->setName('language');

$collection = new Collection();
$collection->setName('languages');
$collection->setLabel('Language Collection');
$collection->setCount(2);
$collection->setTargetElement($languages);
$collection->populateValues(array(
        1, 0
));

$this->add($collection);

2) Do not forget to prepare your form in your controller action:

$form->prepare();

3) Finally, in your view, get all elements of the collection and render them separately:

<?php $elements = $form->get('languages')->getElements(); ?>
<?php //echo $this->formCollection($form->get('languages')); ?>
<?php echo $this->formRow($elements[0]); ?>
<?php echo $this->formRow($elements[1]); ?>
