查询数据未显示在zf2的视图中? [英] Query data not show in view in zf2?

问题描述

我执行了一个索引操作，在该操作中，我使用了学说查询从日历表中选择数据，并且我想使用index.phtml显示数据，但是我的数据不只显示空白页，我如何从控制器显示数据以进行查看? 这是我的代码:

I make an index action in which i used doctrine query to select data from calendar table and i want to show data using index.phtml but my data not show only blank page shown,how i show data from controller to view? here is my code:

 public function indexAction()
    {

        $dm = $this->getServiceLocator()->get('doctrine.documentmanager.odm_default');
        $qb = $dm->createQueryBuilder('Calendar\Document\Calendar');
        $query = $qb->getQuery();
        $calendars = $query->execute();
        return array('calendars' => $calenders)
    }

这是我的index.phtml代码:

and here is my index.phtml code:

 <?php
$calendars = $this->calendars;
$title = 'Calendars by';
$this->headTitle($title);
 ?>

 <h3><?php echo $this->escapeHtml($title); ?></h3>

 <ul>
 <li><a href="<?php echo $this->url('calendar', array('action'=>'create'));?>">Create New Calendar</a></li>
 </ul>

 <h4>Calendars created by you</h4>

 <?php if (is_null($calendars)): ?>

<p>No calendars</p>

   <?php else: ?>

<table class="table">
<tr>
    <th>calendar name</th>
    <th>description</th>
    <th>actions</th>
</tr>
<?php foreach ($calendars as $calendar) : ?>
<tr>
    <td>
        <a href="<?php echo $this->url('calendar',array('action'=>'show', 'id' => $calendar->calendar_id));?>">
                <?php echo $this->escapeHtml($calendar->title);?>
        </a>
    </td>
    <td><?php echo $this->escapeHtml($calendar->description);?></td>
    <td>
        <a href="<?php echo $this->url('calendar',
            array('action'=>'settings', 'id' => $calendar->_id));?>">Settings</a>
        <a href="<?php echo $this->url('calendar',
            array('action'=>'delete', 'id' => $calendar->_id));?>">delete</a>
    </td>
</tr>
<?php endforeach; ?>
</table>

   <?php endif; ?>

这是我的回复:

Doctrine\ODM\MongoDB\Cursor Object
(
    [baseCursor:Doctrine\ODM\MongoDB\Cursor:private] => Doctrine\MongoDB\Cursor Object
        (
            [connection:protected] => Doctrine\MongoDB\Connection Object
                (
                    [mongo:protected] => MongoClient Object
                        (
                            [connected] => 1
                            [status] => 
                            [server:protected] => 
                            [persistent:protected] => 
                        )

我如何在index.phtml中显示查询结果?

how i show query result in index.phtml?

推荐答案

您需要将具有在关联数组中设置的属性的ViewModel返回给应用程序，否则将返回不带属性的默认ViewModel.

You need to return a ViewModel to the application with properties set in an associative array, otherwise a default ViewModel will be returned with no properties.

例如:

return new ViewModel(array(
    'content' => 'foo bar!'
));

然后在您的.phtml文件中:

Then in your .phtml file:

<p><?php print $this->content; ?></p>
