Zend_Form array notation and empty elements names - zend-form

Question

I'want to render:
<input type="text" value="" name="foo[]" />
<input type="text" value="" name="bar[]" />
but Zend_Form_Element require a (string) name, so I need to do:
$this->addElement('text', '1', array(
'belongsTo' => 'foo'
));
$this->addElement('text', '2', array(
'belongsTo' => 'bar'
));
but the output is:
<input id="foo-1" type="text" value="" name="foo[1]" />
<input id="bar-2" type="text" value="" name="bar[2]" />
I can also accept an output like:
<input id="foo-1" type="text" value="" name="foo[1]" />
<input id="bar-1" type="text" value="" name="bar[1]" />
but Zend_Form_Element rewrite elements with the same name
is there a way to do what I need?

Answer 1

For multiple values:
$foo = new Zend_Form_Element_Text('foo');
// Other parameters
$foo->setIsArray(TRUE);
$this->addElement($foo);
Generates: name="foo[]"

If you're looking for given keys such as name="foo[bar]", use:
$bar= new Zend_Form_Element_Text('bar');
// Other parameters
$bar->setBelongsTo('foo');
$this->addElement($bar);

Answer 2

class MyFooForm extends Zend_Form {
public function init() {
$fullNameOpts = array(
'required'=>false,
'label'=>'fullName',
'isArray'=>true,
'validators' => array( array('stringLength', false, array(1, 250) ) )
);
$this->addElement('text' ,'fullName',$fullNameOpts);
// rest of the elements , forms and stuff goes here
}
}
And that does creates
<dd id="fullName-element"><input type="text" class="inputAccesible" value="" id="fullName"name="fullName[]"></dd>
It's on Element.php , in Form , line 512 "isArray" check.
I'm using a regular zend_form, crossValidation with custom validators and i'm pushing subforms to replicate the main form, 'cause the user can add multiple times the same form.
Additionally , I'm too lazy to research custom decorators, i have created one, but it kills subForms and array notation, so i just stick with the regular ones, and that solves it.
I'm at Zf 1.10.
