大侠求助！Thinkphp 如何输出指定值数据

大侠求助！表items有一字段cate_id，我只想输出cate_id=11的数据，具体应该怎么做呢？在网上查阅了好多资料，Thinkphp的开发文档也看了，没有这方面的介绍，求助了
个人感觉主要是$item_mod = m( "items" );这段决定输出数据，但怎么只输出cate_id=11时的数据还请大虾帮助！

<?phpclass shijiuAction extends frontendAction{    public function _initialize( )    {        parent::_initialize( );        $this->_mod = d( "items" );        $this->_cate_mod = d( "items_cate" );    }    public function index( )    {        $month = mktime( 0, 0, 0, date( "m" ), 1, date( "Y" ) );

回复讨论(解决方案)

$item_mod = m( "items" );前面加入$map['cate_id'] = 11;就可以了
不知道楼主要的是不是这个结果，希望对你有帮助。

或者你要在模板页面也可以这样，
在循环items_list的里面加入： //你要输出的数据

在循环items_list的里面加入： //你要输出的数据 我就是想输出cate_id = 11 的数据

好的谢谢啦哈  我试试去  好人一生平安

如果要输出cate_id 不等于 11的值应该怎么表达啊
