Question

我对The Zend框架相对较新，只使用它最多可能需要两个月。我现在试图从我运行的查询中获取结果列表，通过zend paginator类发送它并每页显示4个结果，但是它似乎没有识别它何时有4个结果，我相信有一个我的代码中的错误，但我不能为我的生活看到它，我希望有人在这里能够接受它并帮助我和我可能会告诉我这是我错过的愚蠢。谢谢，这是我写的代码。

我的模型中的查询

public function getAllNews()
{
    $db = Zend_Registry::get('db');

    $sql = "SELECT * FROM $this->_name WHERE flag = 1 ORDER BY created_at";

    $query = $db->query($sql);
    while ($row = $query->fetchAll()) {
        $result[] = $row;
    }

    return $result;
}

这是我的控制器中的代码

function preDispatch()
{
$this->_helper->layout->setLayout('latestnews');
    Zend_Loader::loadClass('newsArticles');
    $allNews = new newsArticles();
    $this->view->allNews = $allNews->getAllnews();
    //die (var_dump($this->view->allNews));
    $data = $this->view->allNews;
    // Instantiate the Zend Paginator and give it the Zend_Db_Select instance  Argument ($selection)
    $paginator = Zend_Paginator::factory($data);
    // Set parameters for paginator
    $paginator->setCurrentPageNumber($this->_getParam("page")); // Note: For this to work of course, your URL must be something like this: http://localhost:8888/index/index/page/1  <- meaning we are currently on page one, and pass that value into the "setCurrentPageNumber"
    $paginator->setItemCountPerPage(1);
    $paginator->setPageRange(4);
    // Make paginator available in your views
    $this->view->paginator = $paginator;
    //die(var_dump($data));
}

以下是构建分页器的视图

    <?php if ($this->pageCount): ?> 
<div class="paginationControl">
<!-- Previous page link --> 
<?php if (isset($this->previous)): ?> 
  <a href="<?= $this->url(array('page' => $this->previous)); ?>">&lt; Previous</a> | 
<?php else: ?> 
  <span class="disabled">&lt; Previous</span> | 
<?php endif; ?> 

<!-- Numbered page links -->
<?php foreach ($this->pagesInRange as $page): ?> 
  <?php if ($page != $this->current): ?>
    <a href="<?= $this->url(array('page' => $page)); ?>"><?= $page; ?></a> | 
  <?php else: ?>
    <?= $page; ?> | 
  <?php endif; ?>
<?php endforeach; ?>

<!-- Next page link --> 
<?php if (isset($this->next)): ?> 
  <a href="<?= $this->url(array('page' => $this->next)); ?>">Next &gt;</a>
<?php else: ?> 
  <span class="disabled">Next &gt;</span>
<?php endif; ?> 
</div> 
<?php endif; ?>

最后代码组成了我的观点

<div id="rightColumn">
                <h3>Latest News</h3>
                <?php if (count($this->paginator)): ?>
                    <ul>
                        <?php foreach ($this->paginator as $item): ?>
                            <?php
                            foreach ($item as $k => $v)
                            {
                                echo "<li>" . $v['title'] . "</li>";
                            }
                            ?>

                        <?php endforeach; ?>
                    </ul>
                <?php endif; ?>

<?= $this->paginationControl($this->paginator, 'Sliding', '/latestnews/partial_pagination_control.phtml'); ?> 
                </div>

我会很乐意为你提供任何帮助。

Answer 1

$ paginator应设置为4，因为您希望一次只显示4条记录：

$paginator->setItemCountPerPage(4);

Answer 2

所以我认为问题的根源在于你的模型类中有getAllNews函数。 Zend_Db fetchAll函数检索与您的查询匹配的所有记录的关联数组。您将返回一个元素的数组，该元素是由select语句检索的所有行的数组。

试试这个：

public function getAllNews()
{
        $db = Zend_Registry::get('db');

        $sql = "SELECT * FROM $this->_name WHERE flag = 1 ORDER BY created_at";

        return $db->fetchAll($sql);
}

Answer 3

如果要限制查询，则不应将值传递给分页。有一个代码适合你

$usersTable = $this->getTable();
        $registerSelect = $usersTable->select()->where('status = ?', 'OK')->order('lastLogin DESC');
        $paginator = new Zend_Paginator(new Zend_Paginator_Adapter_DbTableSelect($registerSelect));
        $paginator->setCurrentPageNumber($page);
        $paginator->setItemCountPerPage($limit);

Zend Pagination - 似乎不限制每页的结果数量
