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=&#39;green&#39;>两次密码相同!</font>";
                      
                      document.getElementById("submit").disabled = 
                      false;
                  }
                  else {
                      document.getElementById("tishi1").innerHTML=
                      "<font color=&#39;red&#39;>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

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

mPDF

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),
