Zend：如何在使用 addElement() 作为工厂时向表单元素添加装饰器？

正如标题所暗示的，我有一个关于 Zend 框架中的装饰器的问题。请考虑以下代码示例：

$this->addElement('select', 'DisplayUntil', array(
    'label' => 'Display until:',
    'multiOptions' => $this->getOptions(),
    'filters' => array(
        'HTMLEntities',
        'StringTrim',
    ),
    'validators' => array(
        'Int',
    ),
));

这是我向表单添加元素的首选方法。在尝试建立最佳实践时，我标准化了使用工厂方法而不是方法链。为什么？我个人发现它更具可读性，并且它缩短了我的自定义表单类的长度，即更少的编码。上面的示例工作得很好，但是，我很难找到使用相同方法添加装饰器的文档或示例。因此，使用相同的代码片段，我假设在添加装饰器时您将执行以下操作：

$this->addElement('select', 'DisplayUntil', array(
    'label' => 'Display until:',
    'multiOptions' => $this->getOptions(),
    'filters' => array(
        'HTMLEntities',
        'StringTrim',
    ),
    'validators' => array(
        'Int',
    ),
    'decorators' => array(
        'ViewHelper', 
        'Label' => array(
            'tag' => 'dt'
        ),
        'HtmlTag' => array(
            'tag' => 'div',
            'openOnly' => true,
            'id' => 'divDisplayUntil',
            'placement' => 'prepend',
        ),
    ),
));

不幸的是，我收到“在注册表中未找到名为 'Dt' 的插件；使用的路径：Zend_Form_Decorator_: Zend/Form/Decorator/”错误消息。我对 Zend 相当陌生，如果有人能向我展示如何使前面的代码示例工作，我将不胜感激。这种方法可能吗？

谢谢你！

As the title implies, I have a question concerning decorators in the Zend Framework. Please consider the following code example:

$this->addElement('select', 'DisplayUntil', array(
    'label' => 'Display until:',
    'multiOptions' => $this->getOptions(),
    'filters' => array(
        'HTMLEntities',
        'StringTrim',
    ),
    'validators' => array(
        'Int',
    ),
));

This is my preferred method for adding elements to a form. In attempting to establish best practices, I have standardized on using factory methods rather than method chaining. Why? I personally find it much more readable and it shortens the length of my custom form class, i.e. less coding. The above example works beautifully, however, I am having a hard time locating documentation or examples where the same method is used for adding decorators. So using the same code snippet, I assumed when adding decorators you would do the following:

$this->addElement('select', 'DisplayUntil', array(
    'label' => 'Display until:',
    'multiOptions' => $this->getOptions(),
    'filters' => array(
        'HTMLEntities',
        'StringTrim',
    ),
    'validators' => array(
        'Int',
    ),
    'decorators' => array(
        'ViewHelper', 
        'Label' => array(
            'tag' => 'dt'
        ),
        'HtmlTag' => array(
            'tag' => 'div',
            'openOnly' => true,
            'id' => 'divDisplayUntil',
            'placement' => 'prepend',
        ),
    ),
));

Unfortunately I receive a "Plugin by name 'Dt' was not found in the registry; used paths: Zend_Form_Decorator_: Zend/Form/Decorator/" error message. I am fairly new to Zend and I would appreciate it if someone could show me how to make the preceding code example work? Is this method even possible?

Thank you!

装饰器似乎多了一层数组。这是来自 1.1x 手册：

$this->addDecorators(array(
    array('ViewHelper'),
    array('Errors'),
    array('Description', array('tag' => 'p', 'class' => 'description')),
    array('HtmlTag', array('tag' => 'dd')),
    array('Label', array('tag' => 'dt')),
));

所以在你的情况下尝试

'decorators' => array(
    array('ViewHelper'), 
    array('Label', array(
        'tag' => 'dt'
        )
    ),
    array('HtmlTag', array(
        'tag' => 'div',
        'openOnly' => true,
        'id' => 'divDisplayUntil',
        'placement' => 'prepend',
        )
    ),
),

Decorators seem to have one more layer of arrays. This is from the 1.1x manual:

$this->addDecorators(array(
    array('ViewHelper'),
    array('Errors'),
    array('Description', array('tag' => 'p', 'class' => 'description')),
    array('HtmlTag', array('tag' => 'dd')),
    array('Label', array('tag' => 'dt')),
));

So in your case try

'decorators' => array(
    array('ViewHelper'), 
    array('Label', array(
        'tag' => 'dt'
        )
    ),
    array('HtmlTag', array(
        'tag' => 'div',
        'openOnly' => true,
        'id' => 'divDisplayUntil',
        'placement' => 'prepend',
        )
    ),
),
