Create your own element type that will accept an array of values, and
then a decorator that will output the various input items.

class My_Element_ArrayElement extends Zend_Form_Element
{
public function init()
{
$this->addPrefixPath('My_Decorator', 'My/Decorator/', 'decorator');
}

public function setValue($value)
{
$this->_value = (array) $value;
}

public function loadDefaultDecorators()
{
if ($this->loadDefaultDecoratorsIsDisabled()) {
return;
}

$decorators = $this->getDecorators();
if (empty($decorators)) {
$this->addDecorator('ArrayElement');
}
}

}

class My_Decorator_ArrayElement extends Zend_Form_Decorator_Abstract
{
public function render($content)
{
$element = $this->getElement();
$view = $element->getView();
$markup = '';
$name = $element->getName() . '[]';

foreach ($element->getValues() as $value) {
$markup .= $view->formHidden($name, $value) . "\n";
}

$separator = $this->getSeparator();
switch ($this->getPlacement()) {
case 'PREPEND':
return $markup . $separator . $content;
case 'APPEND':
default:
return $content . $separator . $markup;
}
}
}
