Thread: Populating form: automatically generate multi-fields for values array

Suppose I want to have a series of text inputs that should be sent in array (mytext[]). How do you force zf to generate mytext elements when you populate the form with a set of values?

Suppose I've this:
[PHP]$this->addElement('text', 'mytext', array(
'label' => 's'
,'isArray' => true
));

// in controller:
$form->populate(array('mytext' => array("0"=> '342', "1" => "123", "2" => "dd")));
[/PHP]
results in

Warning: htmlspecialchars() expects parameter 1 to be string, array given in (...) \library\Zend\View\Abstract.php on line 849

This doesn't work either
[PHP]$this->addElement('text', 'mytext', array(
'label' => 's'
,'isArray' => true
,'value' => array('a', 'b', 'c')
));[/PHP]

Why can you specify an element to be an array when you can't do anything with it?
Ok, try an alternative route:

[PHP]$sub = new Zend_Form_SubForm();
$sub->addElement('text', '0', array(
'label' => 's'
));
$sub->addElement('text', '1', array(
'label' => 's'
));
$this->addSubForm($sub, 'mytext');

// in controller:
$form->populate(array('mytext' => array("0"=> '342', "1" => "123", "2" => "dd")));[/PHP]


this shows the first two fields, but the third ("dd") isn't shown.

I want (and expect) zf to generate mytext-elements for every value I pass it. In the browser I add extra mytext fields dynamically via javascript.
This is a common use case. I obviously miss something, but what?

Any help is greatly appreciated!!!

PS: is the correct forum for Zend_Form?
