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();

<?php if ($pager->haveToPaginate()): ?>
  <div class="pagination">

      <img src="/images/first.png" alt="First page" title="First page" />
    </a>

    <a href="<?php echo url_for('category', $category) ?>?page=<?php echo $pager->getPreviousPage() ?>">
      <img src="/images/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="<?php echo url_for('category', $category) ?>?page=<?php echo $page ?>"><?php echo $page ?></a>
      <?php endif; ?>
    <?php endforeach; ?>
