Zend framework2 zf2表单中文本元素的默认值,zend-framework2,zend-form,Zend Framework2,Zend Form,如何为ZF2表单中的文本元素设置默认值我尝试了以下方法：在视图文件中。这不会获取数据，也不会保存： if($form->get('agencyName')->getValue() === '') $form->get('agencyName')->setValue('Virtual Field Practicum'); 这既不影响视图，也不影响数据库： $this->add(array( 'name' => 'agencyNam

如何为ZF2表单中的文本元素设置默认值

我尝试了以下方法：

在视图文件中。这不会获取数据，也不会保存：

if($form->get('agencyName')->getValue() === '')
    $form->get('agencyName')->setValue('Virtual Field Practicum');

这既不影响视图，也不影响数据库：

$this->add(array(
        'name' => 'agencyName',

        'options' => array(
            'label' => 'Agency Name',
        ),
        'attributes' => array(
            'disabled' => 'disabled',
            'value' => 'Virtual Field Practicum',
        )
    ));

我还尝试用两种方式修改实体，但它并没有影响任何东西：

public function __construct()
{
    //set default agency name
    $this->agencyName = 'Virtual Field Practicum';
}

或：
