查询操作

Action模块　User下的search

 public function search(){
           //判断username是否已经传入，且不为空
           if(isset($_POST['username'])&&$_POST['username']!=null){
               //不管{是出现在$前面还是后面，只有两者紧挨着时花括号才会被当成是界定符号。不要在之间加空格，要不然就会被当作普通的花括号处理
               $where['username']=array('like',"%{$_POST['username']}%");
           }
           if(isset($_POST['sex'])&&$_POST['sex']!=null){
               $where['sex']=array('eq',$_POST['sex']);
           }
           $m=M('User');
           //类似SELECT * FROM `tp_user` WHERE ( `username` LIKE '%李%' ) AND ( `sex` = '0' )
         $data=$m->where($where)->select();
         if($data==null){
             $this->error("没有查询到结果！",'index');
         }
         else{
         $this->assign('data',$data);
         $this->display('index');
         }
       }

User对应的index.html模板

 <div style="width:400px;margin:0 auto;">
 <form action="__URL__/search" method="post">
    姓名：<input type="text" name="username" />性别：<input type="radio" name="sex" value="1" />男<input type="radio" name="sex" value="0" />女
 <input type="submit" value="查询" />

 </form>

 <table border='1' width='400px' align='center'>
     <tr>
         <th>Id</th>
         <th>User</th>
         <th>sex</th>
         <th>操作</th>
     </tr>
     <volist name='data' id='vo'>
        <tr>
                <td><{$vo.id}></td>
                <td><{$vo.username}></td>
                <td><{$vo.sex}></td>
                <td><a href='/thinkphp/test/index.php/User/del/id/<{$vo.id}>'>删除</a>|<a href='/thinkphp/test/index.php/User/modify/id/<{$vo.id}>'>修改</a></td>
        </tr>

     </volist>
 </table>
 <input type="button" value="添加" onclick="jump()"/>
 </div>
