Zend_Form 如何放置<a>在输入文本后面?

问题描述：

我尝试在输入文本后面放置一些 HTML 链接，我尝试这样做:

I try to put some HTML link behind input text and I try to do it's somthing like this:

$aElements[$iKey] = $oName = new Zend_Form_Element_Text($aValue['newsletter_question_answer_id']);
$oName->addDecorator('HtmlTag', array(
                        'tag' => 'a',
                        'href'=>'http://some_url.html',
                        'placement' => Zend_Form_Decorator_Abstract::APPEND
                    ));

我的问题是如何在和之间添加一些东西?

and my question is how can I put somthing between <a> and </a> ?

最好的问候

如果你不想写你自己的装饰器你必须使用回调:

If You don't want to write Your own decorator You have to use callback:

$element->addDecorator('Callback', array(
    'callback'  => function($content, $element, $options) { 
        Zend_Debug::dump($content, 'content'); //elements decorated so far
        Zend_Debug::dump($element, 'element'); //current element
        Zend_Debug::dump($options, 'options'); //other options

        return "<a href=\"{$options['href']}\">{$options['label']}</a>";
    },
    'option' => 'value', //everything but 'callback' and 'placement' gets 
                         //passed to callback as option
    'href'  => 'http://example.com',
    'label' => 'Link!',
    'placement' => Zend_Form_Decorator_Abstract::APPEND
));

当然是php5.3风格的回调，不过你也可以用oldstyle.

Ofcourse it's php5.3 style callback, but You can use oldstyle too.
