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="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>
