Php 如何在视图中呈现表单元素？

我创建了这样一个表单：

class Form_Login extends Zend_Form {

    public function __construct() {

        $this->setMethod('post');
        $elements = array();

        // username
        $element = $this->addElement('text', 'username', array('label' => 'Username') );
        $elements[] = $element;

        // password
        $element = $this->addElement('password', 'password', array('label' => 'Password'));
        $elements[] = $element;

        // submit 
        $element = $this->addElement('submit', 'submit', array('label' => 'Login'));
        $elements[] = $element;

        $this->addElements( $elements );
        $this->addDecorator('ViewHelper');
        $this->setDecorators(array(array('ViewScript', array('viewScript' => 'authentication/login-form.phtml' ))));   
    }
}

<form action='submitlogin' method='post' id='loginform'>  

Login Form

<?=  $this->form->getElement('username');  ?>
<?=  $this->form->getElement('password');  ?>

</form>

<?= $this->element->username ?>

现在，在登录表单.phtml文件中，我呈现如下元素：

class Form_Login extends Zend_Form {

    public function __construct() {

        $this->setMethod('post');
        $elements = array();

        // username
        $element = $this->addElement('text', 'username', array('label' => 'Username') );
        $elements[] = $element;

        // password
        $element = $this->addElement('password', 'password', array('label' => 'Password'));
        $elements[] = $element;

        // submit 
        $element = $this->addElement('submit', 'submit', array('label' => 'Login'));
        $elements[] = $element;

        $this->addElements( $elements );
        $this->addDecorator('ViewHelper');
        $this->setDecorators(array(array('ViewScript', array('viewScript' => 'authentication/login-form.phtml' ))));   
    }
}

<form action='submitlogin' method='post' id='loginform'>  

Login Form

<?=  $this->form->getElement('username');  ?>
<?=  $this->form->getElement('password');  ?>

</form>

<?= $this->element->username ?>

如何在外部脚本中呈现元素…

您可以从视图脚本中调用元素，如下所示：

class Form_Login extends Zend_Form {

    public function __construct() {

        $this->setMethod('post');
        $elements = array();

        // username
        $element = $this->addElement('text', 'username', array('label' => 'Username') );
        $elements[] = $element;

        // password
        $element = $this->addElement('password', 'password', array('label' => 'Password'));
        $elements[] = $element;

        // submit 
        $element = $this->addElement('submit', 'submit', array('label' => 'Login'));
        $elements[] = $element;

        $this->addElements( $elements );
        $this->addDecorator('ViewHelper');
        $this->setDecorators(array(array('ViewScript', array('viewScript' => 'authentication/login-form.phtml' ))));   
    }
}

<form action='submitlogin' method='post' id='loginform'>  

Login Form

<?=  $this->form->getElement('username');  ?>
<?=  $this->form->getElement('password');  ?>

</form>

<?= $this->element->username ?>

对于特定的图元组件，可以使用以下内容：

<? $el = $this->element->username; ?>
<label><?= $el->getLabel() ?></label>
<?= $this->formText($el->getName(), $el->getValue(), $el->getAttribs()) ?>

以下是我的完整解决方案：

Login.php中的表单类：

class Form_Login extends Zend_Form {

    /**
     * Constructor
     */
    public function __construct( $options = null ) {

        parent::__construct( $options );

        // Set the method for the display form to POST
        $this->setMethod('post');

        $elements = array();

        $element = $this->CreateElement('text', 'username');
        $element->setLabel('Username');
        $elements[] = $element;

        $element = $this->CreateElement('password', 'password');
        $element->setLabel('Password');
        $elements[] = $element;

        $element = $this->CreateElement('submit', 'submit');
        $element->setLabel('Login');
        $elements[] = $element;

        $this->addElements( $elements );

        $this->setElementDecorators( array( 'ViewHelper' ) );

        $this->setDecorators( array( array( 'ViewScript', array( 'viewScript' => 'authentication/login-form.phtml' ) ) ) );

    } // end construct


} // end class

登录表单.phtml

<form action=<?= $this->element->getAction() ?> method=<?= $this->element->getMethod() ?> >


<table>
    <tr>
        <td><label><?= $this->element->username->getLabel() ?></label></td>
        <td><?= $this->element->username; ?></td>
    </tr>   
    <tr>
        <td><label><?= $this->element->password->getLabel() ?></label></td>
        <td><?= $this->element->password; ?></td>
    </tr>
</table>

</form>

+1正常。它正在呈现标签和文本字段以及您的上述答案。如何分别渲染标签和文本字段。谢谢请注意，$this->element->username中的“element”指的是表单对象，而不是实际的元素$该->元素->用户名然后引用表单元素对象。只是一个小小的编码约定。过了一段时间，我找到了一个简短而完整的问题解决方案。请看我的回答。。谢谢
