(我跟着this post得到了如何在不使用装饰器的情况下使用Zend_Form的逻辑。)

在我创建Zend_Form对象的操作中,并在呈现它之前将表单分配给视图:

public function indexAction()
{
        $form = new Zend_Form();
        $form->setAction('process')
            ->setMethod('post');

        $username = $form->createElement('text','username');
        $username->addValidator('alnum')
        ->setRequired(true)
        ->addFilter('StringtoLower');

        $description = $form->createElement('textarea','description');
        $description->addValidator('alnum')
                    ->setRequired(false)
                    ->addFilter('StringtoLower');

        $submit = $form->createElement('submit','Submit');

        $form->addElement($username);
        $form->addElement($description);
        $form->addElement($submit);

        $this->view->form = $form;
        $this->view->render('myForm/index.phtml'); //myForm is the actionController

    }

然后我将以下代码添加到它的视图脚本(index.phtml)

<form>
    <table>
        <tr>
            <td><label>Username</label></td>
            <td><?php echo $this->form->getElement('username')->renderElement(); ?></td>
        </tr>
        <tr>
            <td><label>Description</label></td>
            <td><?php echo $this->form->getElement('description')->renderElement(); ?></td>
        </tr>
        <tr>
            <td></td>
            <td><?php echo $this->form->getElement('submit')->renderElement(); ?></td>
        </tr>
    </table>
</form>

但是它出错了

  

消息:装饰者名称元素   不存在

我没有使用装饰器,我的代码有什么问题。

这是完整的自定义错误消息

如何在不使用装饰器的情况下解决此问题

答案 0 :(得分:4)

您实际上需要删除默认装饰器,并添加ViewScript装饰器(可能是错误装饰器)然后渲染它,看一下this文章。

简单示例:

class Demo_Form extends Zend_Form {
public function init() {
    $this->addElement('text', 'username', array( 'decorators' => array( 'ViewHeper', 'Errors' ) ));
    $this->addElement('text', 'lastname', array( 'decorators' => array( 'ViewHeper', 'Errors' ) ));
    $this->setDecorators(array( array('ViewScript' => array( 'script' => 'demoForm.phtml'))));
}
}

使用视图脚本(demoForm.phtml):

<form action="<?php echo $this->escape($this->form->getAction() ?>" method="<?php echo $this->escape($this->form->getMethod() ?>">
<table>
    <tr>
        <td>User Name:</td>
        <td><?php echo $this->form->username; ?></td>
    </tr>
    <tr>
        <td>Last Name:</td>
        <td><?php echo $this->form->lastname; ?></td>
    </tr>
</table>
</form>

您可以完全控制渲染元素的方式和位置,然后在最终视图(来自控制器的视图)上打印您的表单:form; ?&GT;将viewScript渲染到View上。

function indexAction () {

$form = new Zend_form();

..... $this->view->form = $form;

}

在此步骤之后,只需转到path / to / index.phtml 和

<%php echo $this->form;

希望这对你有用,就像我一样!

答案 2 :(得分:0)

从版本1.7开始,您可以渲染单个表单元素装饰器:

echo $form->forename->renderLabel();

echo $form->forename->renderErrors();

我认为你的代码试图找到一个名为element的装饰器,但没有成功。

您可以渲染&#39;元素&#39;像这样:

echo $form->forename->render($view);

话虽如此,我不认为这就是你想要的。因为您将获得默认的附加装饰器。

你可能想要:

echo $form->forename->renderViewHelper()
