推荐答案

不确定您是要设置单个子表单元素的值还是一次设置所有子表单元素的值.不过你可以使用 populate 方法.例如:

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',
    )
));

以下是设置单个字段的几种方法:

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');
