如何从内容中单独打印组显示？

Question

我正在使用Zend Framework和Zend_Form来呈现我的表单.但是当我发现很难定制它时,我决定单独打印元素.

问题是,我不知道如何在显示组内打印单个元素.我知道如何打印我的显示组(字段集),但我需要在其中添加一些东西(比如<div class="spacer"></div>取消float:left.

有没有办法只显示没有内容的组,所以我可以自己单独打印它们？

谢谢您的帮助.

您正在寻找的是'ViewScript'装饰器.它允许您以任何您需要的方式形成您的HTML.这是一个如何工作的简单示例:

表单,简单的搜索表单:

<?php
class Application_Form_Search extends Zend_Form
{
    public function init() {
        // create new element
        $query = $this->createElement('text', 'query');
        // element options
        $query->setLabel('Search Keywords');
        $query->setAttribs(array('placeholder' => 'Query String',
            'size' => 27,
            ));
        // add the element to the form
        $this->addElement($query);
        //build submit button
        $submit = $this->createElement('submit', 'search');
        $submit->setLabel('Search Site');
        $this->addElement($submit);
    }
}

接下来是'部分'这是装饰器,这里是你如何构建html的地方:

<article class="search">
<!-- I get the action and method from the form but they were added in the controller -->
    <form action="<?php echo $this->element->getAction() ?>"
          method="<?php echo $this->element->getMethod() ?>">
        <table>
            <tr>
            <!-- renderLabel() renders the Label decorator for the element
                <th><?php echo $this->element->query->renderLabel() ?></th>
            </tr>
            <tr>
            <!-- renderViewHelper() renders the actual input element, all decorators can be accessed this way -->
                <td><?php echo $this->element->query->renderViewHelper() ?></td>
            </tr>
            <tr>
            <!-- this line renders the submit element as a whole -->
                <td><?php echo $this->element->search ?></td>
            </tr>
        </table> 
    </form>
</article>

最后是控制器代码:

public function preDispatch() {
        //I put this in the preDispatch method because I use it for every action and have it assigned to a placeholder.
        //initiate form
        $searchForm = new Application_Form_Search();
        //set form action
        $searchForm->setAction('/index/display');
        //set label for submit button
        $searchForm->search->setLabel('Search Collection');
        //I add the decorator partial here. The partial .phtml lives under /views/scripts
        $searchForm->setDecorators(array(
            array('ViewScript', array(
                    'viewScript' => '_searchForm.phtml'
            ))
        ));
        //assign the search form to the layout place holder
        //substitute $this->view->form = $form; for a normal action/view
        $this->_helper->layout()->search = $searchForm;
    }

使用法线在您的视图脚本中显示此表单<?php $this->form ?>.

您可以将此方法用于要使用Zend_Form构建的任何表单.因此,将任何元素添加到您自己的fieldset都很简单.
