JavaScriptCookiePHPCookie实现用户登录信息自动填入

本文主要是介绍JavaScriptCookiePHPCookie实现用户登录信息自动填入，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

步骤：

1.登录表单的加载；

2.在加载登录表单后，引入的js会执行，给表单中加载值；

3.在没有cookie的情况下，登录跳转到主页过的服务器会存储cookie;

4.跳转到主页，主页在这里就不再展示啦！

一、登录页面login.html表单

<form action="ServerLogin.php" method="post" 
enctype="application/x-www-form-urlencoded"><input id="us" type="text" name="username" class="username" 
placeholder="Username"><input id="pw" type="password" name="password" class="password"
placeholder="Password"><button type="submit">Sign me in</button><div class="error"><span>+</span></div>
</form>

二、登录页引入js

<!--引入自动添加用户信息的cookie的js-->
<script src="autoAddCookie.js"></script>

三、
文件autoAddCookie.js的cookie获取如下：

$(function () {initialValue();function initialValue() {//jQuery方式
        $("#us").val(getCookieByKey("username"));$("#pw").val(getCookieByKey("password"));//javaScript方式
//        document.getElementById("us").value = getCookieByKey("username");
//        document.getElementById("pw").value = getCookieByKey("password");
    }//javaScript Cookie获取
    function getCookieByKey(key) {var cookie = document.cookie.split(";");for (i = 0; i < cookie.length; i++) {var value = cookie[i].trim();if (value.indexOf(key) == 0) {v = value.split("=");return v[1];}}}
});

javaScript Cookies的设置获取详解在我的下边博文：http://blog.csdn.net/u013005050/article/details/51966626

四、服务器文件设置PHPcookie,ServerCookie.php

<?php
/**
 * Created by PhpStorm.
 * User: 洋   汪
 * Date: 2016/7/19
 * Time: 11:53
 */
header("Content-type:text/html;charset=utf-8");
include "data.php";
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if ($_POST["username"] == $info["username"] && $_POST["password"] == $info["password"]) {
        //设置cookie
        setCookieByKey($_POST["username"], $_POST["password"]);

        //设置session
        $mySession = $_POST;
        $mySession = array_merge($mySession, array("loginIp" => $_SERVER["REMOTE_ADDR"], "loginTime" => time()));
        setSession($mySession);
        echo "<script>window.location.href ='index.php';</script>";
    } else {
        echo "<script>alert('用户名或密码错误！！！');</script>";
    }
} else {
    echo "<script>
        alert('请登录！！！');
        window.location.href = 'login.html';
</script>";
}
//设置session
function setSession(array $mySession)
{
    session_start();
//    $_SESSION = $mySession;
//Array ( [username] => wangyang [password] => 123456 [loginIp] => 127.0.0.1 [login_time] => 1468915628 )
//    print_r($_SESSION);

    $_SESSION["username"] = $mySession["username"];
    $_SESSION["password"] = $mySession["password"];
    $_SESSION["loginIp"] = $mySession["loginIp"];
    $_SESSION["loginTime"] = $mySession["loginTime"];
}

//设置Cookie
function setCookieByKey($username, $password)
{
    setcookie("username", $username, time() + 120);
    setcookie("password", $password, time() + 120);
}
