关于前端使用symfony套模的问题

Question

这是HTML代码

 <form action="" method="post" id="personal-index" class="personal-index">
      <table border="1" cellpadding="0" cellspacing="0">
        <tbody>
          <tr>
            <td colspan="2" align="center"><a href="" id="header"><img src="http://img1.2345.com/duoteimg/qqTxImg/11/2012091910313510745.jpg" width="60" height="60" id="avatar"><span id="username">头像</span></a></td>
          </tr>
          <tr>
            <td  align="center"><a href="{{ path('user_personal_points') }}">积分:245</a></td>
            <td  align="center"><a href="{{ path('user_personal_coupon') }}">优惠券:3</a></td>
          </tr>
          <tr>
            <td  align="center"><a href="{{ path('user_personal_recharge') }}">充值</a></td>
            <td  align="center"><a href="">消费记录</a></td>
          </tr>
          <tr>
            <td  align="center"><a href="{{ path('user_personal_points') }}">我的积分</a></td>
            <td  align="center"><a href="{{ path('user_personal_coupon') }}">我的优惠券</a></td>
          </tr>
          <tr>
            <td  align="center"><a href="javascript:;">适用门店</a></td>
            <td  align="center"><a href="">二维码</a></td>
          </tr>
          <tr>
            <td  align="center"><a href="{{ path('user_personal_info') }}">个人信息</a></td>
            <td  align="center"><a href="{{ path('user_personal_coupon') }}">使用帮助</a></td>
          </tr>
        </tbody>
      </table>
    </form>

这是 路由

 user_personal:
    path:     /personal
    defaults: { _controller: UserBundle:Personal:index }

这是控制器

 public function indexAction()
    {
        // $user_id =$this->getSession('user_id');
       $user_id =1;
        if (empty($user_id)) {
            return $this->redirect($this->generateUrl('user_index'));
        } else {
            $conn = $this->get('database_connection');

            $user = $conn->fetchAssoc("SELECT id, avatar, avatar_update, name, points FROM user WHERE id =?", array($user_id));

            $coupon = $conn->fetchColumn("SELECT COUNT(id) FROM user_coupon WHERE user_id =? AND is_used = 0 AND end_date >= NOW()", array($user_id));

        }
        return $this->render('UserBundle:Personal:index.html.twig', array('user' => $user, 'coupon' => $coupon));
    }

我要怎么写代码，才能把数据库的avatar,points,在页面加载时显示在头像和积分上，而不是我在HTML代码里自己填的，听说用AJAX，但是不会写，求告知代码
