我对 Zend-Framework 的世界还很陌生，并且已经接管了一个使用 zend-framework 的网站。现在其中一个页面上有一个错误，我无法弄清楚。我认为这与 Zend Paginator 有关，但不确定。

这是我遇到问题的部分控制器中的代码：

$currentPage = $this->_getParam('page');
$numWebsitesFullOnline = $websites->getWebsitesFullOnline();

$select = $websites->select();
$select->setIntegrityCheck(false);
$select->from(array('w' => 'websites'), array('id', 'online', 'kw_adjective', 'kw_name', 'kw_location', 'url', 'email', 'address', 'ftp_server', 'ftp_username', 'ftp_password', 'ftp_folder', 'phone_number', 'indexed', 'youtube_position', 'twitter_user', 'facebook_id', 'video_made', 'image1_id', 'image2_id', 'image3_id', 'bg_color', 'dark_color', 'light_color', 'links_color', 'text_color', 'google_account', 'ganalytics', 'gmaps_status', 'google_position', 'gmap_position', 'hp1', 'hp2', 'hp3', 'hp4', 'hp5', 'hp6', 'hp7', 'hp8', 'hp9', 'hp10', 'about1_id', 'about2_id', 'about3_id', 'tip1_id', 'tip2_id', 'tip3_id', 'contact_texts_id', 'quote_texts_id', 'demographics_id'))
    ->join(array('d' => 'demographics'), 'w.demographics_id = d.id', array('total_population'))
    ->order(array('total_population DESC', 'kw_location'));
$paginator = new Zend_Paginator(new Zend_Paginator_Adapter_DbSelect($select));
$paginator->setItemCountPerPage(50);
$paginator->setCurrentPageNumber($currentPage);
$paginator->setPageRange(($paginator->getTotalItemCount() / 50) + 1);
$this->view->paginator = $paginator;

$numWebsitesOnline = $websites->getWebsitesOnline();

在 php 页面上，我有这段代码可以将数据库中的网站调用到列表中：

<p class="red">
Websites online: <?php echo $this->numOnline; ?>
</p>

<?php print_r(count($this->paginator)); ?>

<?php if(count($this->paginator)): ?>

print_r(count($this->paginator)); 行返回“0”，$this->numOnline; 行返回 1。所以它看到数据库的网站表中有一行，但它没有返回任何内容到页面并列出网站表中的行。不确定这是否是导致此原因的分页器返回 0 或我不知道的其他内容。

我不确定，但尝试使用 joinLeft 而不是 join，也许只是网站表和人口统计表之间的关系导致了这个结果。
