Good day! I just created a subform from my existing zend form and procures this data when form submits. Based on posted data (the quantity_ elements), I would like to set the values to开发者_运维技巧 subform elements. Is it possible? Thanks in advance. cheers and happy coding!

Not sure whether you want to set values of individual subform elements or all of them at once. Nevertheless you can use populate method. For example:

 $yourForm->populate(array(
    'subQuantity' => array(
        'quantity_6' => 'some value 1',
        'quantity_16' => 'some value 2',
        'quantity_18' => 'some value 3',
    )
));

EDIT:

Here are few ways of setting individual fields:

$yourForm->populate(array(
        'subQuantity' => array(     
            'quantity_16' => 'some value',
        )
 ));

 // OR

 $yourForm->getSubForm('subQuantity')->getElement('quantity_16')->setValue('some value');

 // this also should work (not sure if it works with underscore in 'quantity_16' though)

 $yourForm->subQuantity->quantity_16->setValue('some value');

    $formSuper = new ContractLink_Form_ContractAllotmentSuper();
    foreach($allotments as $key => $allotment)
    {
        $form = new ContractLink_Form_ContractAllotment();
        $form->populate($allotment);
        $formSuper->addSubForm($form, 'contractAllotmentForm' . $key);
    }
