登錄跳轉到doLogin后，只顯示個驗證碼……改了很多遍，還是只顯示驗證碼，請教大神，這是怎么回事?。?/h1>

代碼如下：

doLogin.php

<?php
require_once?'../include.php';
$username=$_POST['username'];
$username=addslashes($username);
$password=md5($_POST['password']);
$verify=$_POST['verify'];
$verify1=$_SESSION['verify'];
$autoFlag=$_POST['autoFlag'];
if($verify==$verify1){
	$sql="select?*?from?mzjyb_admin?where?username='{$username}'?and?password='{$password}'";
	$row=checkAdmin($sql);
	if($row){
		//如果選了一周內自動登陸
		if($autoFlag){
			setcookie("adminId",$row['id'],time()+7*24*3600);
			setcookie("adminName",$row['username'],time()+7*24*3600);
		}
		$_SESSION['adminName']=$row['username'];
		$_SESSION['adminId']=$row['id'];
		alertMes("登陸成功","index.php");
	}else{
		alertMes("登陸失敗，重新登陸","login.php");
	}
}else{
	alertMes("驗證碼錯誤","login.php");
