Question

我正在尝试使用zend在jquery移动框架中实现分页。我有以下代码来自控制器，

...
        $message_list = $this->help->browse($browseArray); 
        $this->view->vCount = count($message_list); 
        $paginator = Zend_Paginator::factory($message_list);
        $page = ($postData['page'] > 0) ? $postData['page'] : 1;
        $paginator->setCurrentPageNumber($page);
        $paginator->setItemCountPerPage(10);
        $paginator->setPageRange(5);

        $this->view->message_list = $paginator;   
....

我还从模板页面

获取了以下代码

....
    <ul data-role="listview"  data-theme="e">
        <?php foreach ($this->message_list as $key => $value) { ?>
            <li>
                <img src="<?php echo BASE_URL; ?>public/common/images/mobile/jqueryMobile200Thumb.jpg" alt="" />
                <h3><a href="<?php echo $this->url(array("controller" => "help", "action" => "dohelp", "id" => $value['helpid'])); ?>"><?php echo $value['title']; ?></a></h3>
                <p><?php echo $value['content']; ?></p>
            </li>
        <?php } ?>    
            <li>
                <?php echo $this->paginationControl($this->message_list, 'Sliding', 'pagination.phtml'); ?>
            </li>           
    </ul>
....

当我运行该网站时，我得到以下异常

        Exception information:

        Message: No paginator instance provided or incorrect type
        Stack trace:

        #0 [internal function]: Zend_View_Helper_PaginationControl->paginationControl(NULL, 'Sliding', 'pagination.phtm...')

    ....

我在这方面做错了什么。请帮助我。

Answer 1

尝试这种方式：

$paginator = new Zend_Paginator(new Zend_Paginator_Adapter_Array($message_list));

要回答您的问题，系统会显示错误，因为$this->message_list null尝试调试原因null

Answer 2

检查您是否正确设置了视图对象中的$paginator变量。我有这种情况，发现我没有正确这样做。

没有提供paginator实例或者zend中的类型不正确？
