调用函数的代码：

<?php

require_once '../include.php';

$username=$_POST['username'];

$password=md5($_POST['password']);

$verify=$_POST['verify'];

$verify1=$_SESSION['verify'];

$autoLogin=$_POST['autologin'];

if($verify==$verify1){

    $sql="select * from imooc_admin where username='{$username}' and password='{$password}'";

    $row=checkAdmin($sql);

    if($row){

        if($autoLogin){

            setcookie("adminId",$row['id'],time()+7*24*3600);

            setcookie("adminName",$row['name'],time()+7*24*3600);

        }

        $_SESSION['adminName']=$row['username'];

        header("location:index.php");

    }

    else{

        alertM("登录失败，重新登录","login.php");

    }

}

else{

    alertM("验证码错误，重新登录","login.php");

}

函数的代码：

<?php

function alertM($mes,$url){

    echo "<script language='javascript'>alert($mes);</script>";

    echo "<script>window.location=$url;</script>";

}

?>

包含地址的代码：

<?php 

header("content-type:text/html;charset=utf-8");

date_default_timezone_set("PRC");

session_start();

define("ROOT",dirname(__FILE__));

set_include_path(".".PATH_SEPARATOR.ROOT."./lib".PATH_SEPARATOR.ROOT."./core".PATH_SEPARATOR.ROOT."./configs".PATH_SEPARATOR.get_include_path());

require_once 'image.php';

require_once 'string.php';

require_once "configs.php";

require_once 'mysql.php';

require_once 'admin.inc.php';

require_once 'common.php';
