所以我从几天开始就在这里进行搜索，但找不到适当的解决方案，我的问题是我准备好登录系统并有效，但是问题是我试图设置检查我的复选框时，它没有设置cookie。我有三个文件
- studentlogin.php（用户界面）
- loginprocess.js（包含用于调用login.php的ajax方法的jQuery）
-
login.php（实际逻辑）
-
StudentLogin.php
<?php session_start(); if(isset($_cookie['eno'])) { header('location:profile.php'); exit(); } ?> <!DOCTYPE html> <html lang='en'> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>LMS | Login</title> <link rel="stylesheet" href="css/style.css"> <script type="text/javascript" src="js/jquery.js"></script> <script type="text/javascript" src="js/processlogin.js"></script> </head> <body> <div id="wrap"> <?php include 'header.php';?> <div id="content"> <section> <article id="logform"> <form action="" id="log"> <fieldset> <legend>Login Here</legend> <table> <tr> <td> <label for="eno">Enrollment No:<span class='err' id='err_eno'>*Require</span></label> </td> </tr> <tr> <td> <input type="text" name="eno" id="eno" value="" placeholder='Enter Enrollment No' required/> </td> </tr> <tr> <td> <label for="pw">Password:<span class='err' id='err_pw'>*Require</span></label> </td> </tr> <tr> <td> <input type="password" name="pw" id="pw" value="" placeholder='Your Password' required/> </td> <tr> <td> <input type="checkbox" name="cb" checked="checked"> <label>Keep me signed in.</label> </td> </tr> <tr> <td colspan='2'> <span id="err"></span> </td> </tr> <tr> <td> <input type="submit" name="submit" id="submit_btn" value="Login" /> </td> </tr> <tr> <td> <input type="reset" name="reset" value="Reset" /> </td> </tr> <tr> <td> <label>New user?<a href="studentregistration.php">Register here</a></label> </td> </tr> <tr> <td> <label>Forgot your password?<a href="resetpassword.php">Click here</a></label> </td> </tr> </table> </fieldset> </form> </article> </section> </div> <?php include 'footer.php'; ?> </div> </body> </html> -
loginprocess.php
$('#submit_btn').click(function(){ var dataString = $('#log').serialize(); //alert (dataString);return false; $.ajax({ type:"POST", url:"script/login.php", data:dataString, success:function(x) { if(x =='') { //Handle Error Here $('#err').html("<p class='err'>Please provide right combination</p>"); } else if(x == '1') { window.location='profile.php'; } } }); return false; }); -
login.php
<?php error_reporting(0); session_start(); include "../db/connect.php"; $password = $_POST['pw']; $eno = $_POST['eno']; $password_hash = md5($password); if(!empty($eno) && !empty($password)) { $query ="select * from users where eno = '$eno' AND password = '$password_hash'"; $result = $db->query($query); if($result->num_rows) { $_SESSION['login'] = $_POST['eno']; //echo"<script>alert($_SESSION['login']);</script>" if(isset($_POST['cb'])) { setcookie("eno",$eno,time()+3600); } echo '1'; } else { setcookie('eno','',time()-3600); session_regenerate_id(); session_destroy(); echo ''; } } else { session_regenerate_id(); session_destroy(); } ?>
没有看来没有错，但是您的$ _cookie应该是$ _COOKIE
session_start();
if(isset($_COOKIE['eno']))
{
header('location:profile.php');
exit();
}
希望是。
