thinkphp会员登录问题

<?php<br />session_start();<br />header('Content-Type:text/html; charset=utf-8');<br />class AdminAction extends Action{<br />      public function index(){<br />	  if(isset($_POST['username'])){<br />	        if(isset($_POST['username'])&&isset($_POST['password'])){<br />			    $db=M();<br />				$select=$db->query("select * from developers where username=".$POST['username']." and password=".$_POST['password']."");<br />				if($select){<br />				    $_SESSION['admin']=$_POST['username'];<br />					$this->redirect('Index/index','',2,'用户'.$_POST['username'].'登录成功!');<br />                 }else{<br />					$this->redirect('Index/index','',2,'用户名或者密码不正确');<br />					}<br />				}else{<br />				    $this->redirect('Index/index','',2,'用户名或密码不能为空!');<br />					}<br />					}<br />					$this->display();<br />					}<br />	<br />    <br /><br />	}<br />	?>

这是AdminAction代码,不知道怎么回事,不管输入什么或者不输人它都提示用户名或者密码不正确,为什么呢?哪的问题?
