注册页四栏: 1.用户名 2.密码 3.二次输入密码 4.昵称 前端代码略,看核心部分. 1.用户名前端ajax $("#uid").blur(function(){ //取数据 var uid = $(this).val(); //取数据库进行匹配 $.ajax({ url:"__CONTROLLER__/jiance", //jiance控制器在TP的路径 data:{uid:uid}, type:"POST", dataType:"JSON", success: function(data){ if(data.trim()=="OK") { $("#tishi").html("该用户名可用"); $("#tishi").css("color","green"); } else { $("#tishi").html("该用户名不可用!"); $("#tishi").css("color","red"); } } }) }) 1.使用blur事件注册用户名,当用户输入用户名结束,鼠标点击用户名输入栏以外区域,若输入栏后面提示绿色信息用户名可用,反之不可用.
1.TP内用以验证用户名的后台jiance控制器 <? LoginController = ["uid" = M("user" = ->where()->find((["uid"]==->->ajaxReturn("NO"->ajaxReturn("OK"->
2、3密码问题前端JS代码 function validate() { var pwd1 = document.getElementById("pwd").value; var pwd2 = document.getElementById("pwd1").value; <!-- 对比两次输入的密码 --> if(pwd1 == pwd2) { document.getElementById("tishi1").innerHTML= "<font color='green'>两次密码相同!</font>"; document.getElementById("submit").disabled = false; } else { document.getElementById("tishi1").innerHTML= "<font color='red'>两次密码不相同!</font>"; document.getElementById("submit").disabled = true; } }
1.拉取两个p的值赋值给两个变量,判断两个变量是否相等. 如果相等,写入提示"密码相同",执行代码. 如不相等,写入提示"两次密码输入不同",提交功能不执行.
Background zhuce controller
<?php namespace Home\Controller; use Think\Controller; class LoginController extends Controller{ public function zhuce(){ $uid = $_POST["uid"]; $pwd = $_POST["pwd"]; $name = $_POST["name"]; if($uid==uid){ $this->show(); }else{ $n = M("user"); $n->create(); $arr = $n->add(); $this->ajaxReturn($arr,"TEXT"); $this->show(); } } }
1. Send three parameters to the background. If the uid of the database is the same as $uid, then the page will be displayed directly
Vice versa 1.<span class="com">Instantiate the user model</span>
<span class="com">Create a data object based on the POST data submitted by the form</span>
4. Return data
5. Display page

Load balancing affects session management, but can be resolved with session replication, session stickiness, and centralized session storage. 1. Session Replication Copy session data between servers. 2. Session stickiness directs user requests to the same server. 3. Centralized session storage uses independent servers such as Redis to store session data to ensure data sharing.

Alternatives to PHP sessions include Cookies, Token-based Authentication, Database-based Sessions, and Redis/Memcached. 1.Cookies manage sessions by storing data on the client, which is simple but low in security. 2.Token-based Authentication uses tokens to verify users, which is highly secure but requires additional logic. 3.Database-basedSessions stores data in the database, which has good scalability but may affect performance. 4. Redis/Memcached uses distributed cache to improve performance and scalability, but requires additional matching

Sessionhijacking refers to an attacker impersonating a user by obtaining the user's sessionID. Prevention methods include: 1) encrypting communication using HTTPS; 2) verifying the source of the sessionID; 3) using a secure sessionID generation algorithm; 4) regularly updating the sessionID.

The article discusses PHP, detailing its full form, main uses in web development, comparison with Python and Java, and its ease of learning for beginners.

PHP handles form data using $\_POST and $\_GET superglobals, with security ensured through validation, sanitization, and secure database interactions.

The article compares PHP and ASP.NET, focusing on their suitability for large-scale web applications, performance differences, and security features. Both are viable for large projects, but PHP is open-source and platform-independent, while ASP.NET,

PHP's case sensitivity varies: functions are insensitive, while variables and classes are sensitive. Best practices include consistent naming and using case-insensitive functions for comparisons.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
