symfony分页

1.action.class.php
  

    $q = Doctrine_Core::getTable('cmsContent')->findAll();
   //分页
   $this->pg=new sfDoctrinePager('modelName',3);
   $this->pg->setQuery($q);
   $this->pg->setPage($page,1);
   $this->pg->init();

2.模板代码：
 

php if ($pager->haveToPaginate()): ?>
  <div class="pagination">
    <a href="?page=1">
      <img src="/p_w_picpaths/first.png" alt="First page" title="First page" />
    a>

    <a href="?page=getPreviousPage() ?>">
      <img src="/p_w_picpaths/previous.png" alt="Previous page" title="Previous page" />
    a>

    php foreach ($pager->getLinks() as $page): ?>
      php if ($page == $pager->getPage()): ?>
        php echo $page ?>
      php else: ?>
        <a href="?page=">php echo $page ?>a>
      php endif; ?>
    php endforeach; ?>

    <a href="?page=getNextPage() ?>">
      <img src="/p_w_picpaths/next.png" alt="Next page" title="Next page" />
    a>

    <a href="?page=getLastPage() ?>">
      <img src="/p_w_picpaths/last.png" alt="Last page" title="Last page" />
    a>
  div>
php endif; ?>

<div class="pagination_desc">
  <strong>php echo count($pager) ?>strong> jobs in this category

  php if ($pager->haveToPaginate()): ?>
    - page <strong>php echo $pager->getPage() ?>/php echo $pager->getLastPage() ?>strong>
  php endif; ?>
div>
