Question

I have a question about the zend_form_element_checkbox from zend.

I have a form with multiple checkboxes. And when I send this form, I logically receive an array of params that look like that :

array("controller" => my_controller, ...., "checkbox_name" => array ("0" => firstCheckedValue, "1" => secondCheckedValue, ...) )

I create each element this way :

$checkbox = new Zend_Form_Element_Checkbox('checkbox_name');
$checkbox->setCheckedValue($valueVar)->setIsArray(true);
$this->addElement($checkbox);

And I display each one like that :

$this->form->checkbox_name->renderViewHelper();

But I would like to have the received params format this way :

array("controller" => my_controller, ...., "checkbox_name" => array ("firstCheckedValue" => false, "secondCheckedValue" => true, ...) )

In other words, I want the HTML checkboxes look like that :

<input type="checkbox" value="true" name="checkbox_name[firstCheckedValue]">
<input type="checkbox" value="false" name="checkbox_name[secondCheckedValue]">
...

(the boolean value is not for the checked state of the checkbox).

How can I do that?

Try:

$checkbox = new Zend_Form_Element_Checkbox('first');
$checkbox->setCheckedValue($valueVar)->setIsArray(true)->setBelongsTo('checkbox_name');
$this->addElement($checkbox);
$checkbox = new Zend_Form_Element_Checkbox('second');
$checkbox->setCheckedValue($valueVar)->setIsArray(true)->setBelongsTo('checkbox_name');
$this->addElement($checkbox);

Zend_Form::setElementsBelongTo($array): Using this method, you can
specify the name of an array to which all elements of the form belong.
You can determine the name using the getElementsBelongTo() accessor.
