Zend 1.11，装饰器文件位置

Question

我到处搜索，但找不到答案，所以问题是，装饰器类必须在哪里，让我们看一个例子：

我有 application/forms/Guestbook.php

class Application_Form_Guestbook extends Zend_Form
{

    public function init()
    {

        $this->addPrefixPath('My_Decorator', '/application/forms/decorator', 'decorator');

        $this->setMethod('post');
        $this->addElement('text', 'email', array(
            'label' => 'Your email address',
            'require' => true,
            'filters' => array('StringTrim'),
            'validators' => array('EmailAddress'),
            //'prefixPath' => array('decorator' => array('My_Decorator' => 'application/forms/decorator')),
            'decorators' => array(array('SimpleInput'))));



        // Add the comment element
        $this->addElement('textarea', 'comment', array(
            'label' => 'Please Comment:',
            'required' => true,
            'validators' => array(
                array('validator' => 'StringLength', 'options' => array(0, 20))
            )
        ));

        // Add a captcha
        $this->addElement('captcha', 'captcha', array(
            'label' => 'Please enter the 5 letters displayed below:',
            'required' => true,
            'captcha' => array(
                'captcha' => 'Figlet',
                'wordLen' => 5,
                'timeout' => 300
            )
        ));

        $this->addElement('submit', 'submit', array('ignore' => true, 'label' => 'Sign Guestbook'));
        $this->addElement('hash', 'csrf', array('ignore' => true));
    }

}

并拥有 application/forms/decorator/SimpleInput.php

class My_Decorator_SimpleInput extends Zend_Form_Decorator_Abstract
{

    protected $_format = '<label for="%s">%s !!!!!!</label><input id="%s" name="%s" type="text" value="%s"/>';

    public function render($content)
    {
        $element = $content->getElement();
        $name = htmlentities($element->getFullyQualifiedName());
        $label = htmlentities($element->getLabel());
        $id = htmlentities($element->getId());
        $value = htmlentities($element->getValue());

        $markup = sprintf($this->_format, $name, $label, $id, $name, $value);

        return $markup;
    }

}

当我尝试启动页面时，我在加载装饰器时出错：

An error occurred
Application error

此示例来自快速指南。问题是这些装饰器的位置必须在哪里（默认位置），或者我如何加载它们以及我应该写哪个“路径/到/装饰器”（从根\应用程序\表单文件夹？），因为 Zend 中的文档通常很难看。 .. =\

Answer 1

编辑#3。

我认为问题可能在于 Zend 不喜欢您设置路径的方式。 /application 是一个绝对路径，可能无法解决您认为的问题。

试试：

$this->addPrefixPath('My_Decorator', APPLICATION_PATH . '/forms/decorator', 'decorator');

这样路径一定是好的。 Zend 很可能正在 /public/application/etc... 中查找您使用它的方式。

希望对您有所帮助！

Answer 2

装饰器和其他类一样使用Autoloader加载，所以装饰器需要按照类名来放置：

例如。类My_Decorator_Something 在library/My/Decorator/Something.php

在这种情况下，最好的选择似乎是改进您的装饰器类命名。

但是，如果您需要其他自定义位置，则需要编写并注册您自己的自动加载器。
