This article mainly records the entire process of developing the PHP jQuery registration module, including filling in the column user name, email, password, repeated password, verification code, etc. It is very detailed and is recommended to everyone
Written one A simple PHP jQuery registration module. The columns that need to be filled in include user name, email, password, repeated password and verification code. The functions and requirements of each column are as follows:
When making this module, we largely drew on the functions and styles of NetEase Registration (http://reg.163.com/reg/reg.jsp?product=urs). However, NetEase’s approach to judging each column is that it does not provide any real-time detection results when entering text, and only displays the detection results when the column loses focus. I think this approach will make The user's vision is relatively unified when typing. What he sees is the prompt about the requirements of the column, and there will be no interruption of other information, but at the same time, he will not get the detection prompt of the character being entered. So when I was working on this function, I made corresponding enhancements to some information that I thought needed real-time prompts, such as the length of the username exceeding the limit and the length and strength of the password, and made a simple judgment on the caps lock of the mailbox. .
Note: The submit button type of the form is button instead of submit, so the carriage return (keydown) of all columns is uniformly set to move the focus to the next column, except for the last column verification code, which is in the verification code Using a carriage return (keydown) in a column will trigger a submission event.
Function Analysis
Username column:
Process
①The page will get focus after loading, and the initial description text will appear when it gets focus;
②Click the user name input box with the mouse, and the initial description text will appear;
③Enter the characters, and you will be prompted immediately to see if the length requirement is met;
④When the focus is lost, first judge whether it is empty, which is When it is empty, the prompt cannot be empty; when it is not empty and the length meets the requirements, it starts to detect whether the user name has been registered;
⑤The user name has been registered, and a prompt is given. If it is not registered, it prompts that it can be registered;
⑥When the focus is obtained again, no matter whether there is input in the input box or whether the input meets the requirements, the initial description text will appear
⑦When you press Enter, the focus will be moved to the mailbox column
Picture:
Details
You can use any characters, and the number of words is limited to: Chinese, no more than 7 Chinese characters, English, numbers or symbols The length does not exceed 14 letters, numbers or symbols, that is, it does not exceed 14 characters
Regarding placeholders (character length), a placeholder for a Chinese character is 2, and a placeholder for an English (number) Is 1, you can use the php statement to calculate the length of the character
<?php //php.ini开启了php_mbstring.dll扩展 $str="博客园小dee"; echo (strlen($str)+mb_strlen($str,'utf-8'))/2;
Output: 11
And strlen($str) output is 15: 4*3 3, Chinese characters are encoded in utf-8 The bottom occupies 3 bytes, and English occupies 1.
mb_strlen($str,'utf-8') outputs 7: the length of a Chinese character is 1,
If you use jquery length to output this string, alert($("#uname").val().length), you will get a length of 7,
should pay attention to this.
At the same time, the user name cannot contain spaces at both ends. During detection and registration, the program will automatically filter the spaces at both ends of the user name.
register.html HTML code snippet of the username column:

①When initially gaining focus, gaining focus again, or clicking
②Detect the length in real time when inputting
③When deleting to empty space without losing focus, use a blue icon to prompt that it cannot be empty - the user is It does not look abrupt when inputting
④Losses focus and is not empty, detects whether it is registered (very short, fleeting)
⑤When losing focus Empty, can be registered, has been registered
Email Column:
Process①When the column is focused or clicked, a description will appear regardless of whether the column is empty, filled in correctly or filled in incorrectly. Word;②用户输入时出现下拉菜单显示多种邮件后缀供用户选择；
③失去焦点时首先判断邮箱格式是否正确，如果正确则检测邮箱是否被注册 ；
④在使用回车选择下拉菜单时，将自动填充邮箱栏目；没有出现下拉菜单时，将焦点移至密码栏目

密码栏目：
要求
①6-16个个字符，区分大小写（参考豆瓣和网易）
②密码不能为同一字符
③实时提示是否符合要求以及判断并显示密码强度，：
1.输入时如果为空(删除时)则用蓝色符号提示不能为空，超过长度时用红色符号
2.密码满足长度但是为相同字符的组合时：密码太简单，请尝试数字、字母和下划线的组合
3.密码强度判断有多种规则，有直接依据长度和组合规则作出判断，也有给每种长度和组合设置分数，通过验证实际密码的情况计算出最后分数来判断强弱。在这个模块中采用比较简单的一种形式，也是网易注册采用的方法：
密码满足长度且全部为不同字母、全部为不同数字或全部为不同符号时为弱：弱：试试字母、数字、符号混搭
密码满足长度且为数字、字母和符号任意两种组合时为中
密码满足长度且为数字、字母和符号三种组合时为强
④输入时大写提示

使用协议：默认勾选；
register.html相应代码：
<span class="fuwu">
<input type="checkbox" name="agree" id="agree" checked="checked">
<label for="agree">我同意 <a href="#">" 服务条款 "</a> 和 <a href="#">" 网络游戏用户隐私权保护和个人信息利用政策 "</a>
</label>
</span>register.js相应代码：
if($("#agree").prop("checked") == true){
fuwuval = true;
}
$("#agree").click(function(){
if($("#agree").prop("checked") == true){
fuwuval = true;
$("#sub").css("background","#69b3f2");
}else{
$("#sub").css({"background":"#f2f2f2","cursor":"default"});
}
});效果图：
①勾选之后
②未勾选
提交按钮：检测是否所有栏目都填写正确，否则所有填写错误的栏目将给出错误提示。全部填写正确后提交并且发送验证邮件到注册邮箱中，邮件的验证地址在3日后失效
首先在register.js开始部分定义几个参数：nameval,emailval,pwdval,rpwdval,yzmval,fuwuval，全部设为0；当相应栏目符合规定之后，把相应的参数设为true。当所有的参数都为true之后，提交至registerChk.php，否则return false。
register.html相应代码：
<button type="button" id="sub">立即注册</button>
register.js相应代码：
参数设置：
var nameval,emailval,pwdval,rpwdval,yzmval,fuwuval = 0;
提交事件：
function formsub(){
if(nameval != true || emailval!=true || pwdval!=true || rpwdval!=true || yzmval!=true || fuwuval!=true){
//当邮箱有下拉菜单时点击提交按钮时不会自动收回菜单，因为下面的return false，所以在return false之前判断下拉菜单是否弹出
if(nameval != true && $("#unamechk").val()!=""){
var errorMsg = '请输入用户名';
error($("#namechk"),errorMsg);
}
if($(".autoul").show()){
$(".autoul").hide();
}
//以下是不会自动获得焦点的栏目如果为空时，点击注册按钮给出错误提示
if($("#uemail").val() == ""){
var errorMsg = '邮箱不能为空';
error($("#uemailchk"),errorMsg);
}
if($("#upwd").val() == ""){
var errorMsg = '密码不能为空';
error($("#upwdchk"),errorMsg);
}
if($("#rupwd").val() == ""){
var errorMsg = '请再次输入你的密码';
error($("#rupwdchk"),errorMsg);
}
if($("#yzm").val() == ""){
var errorMsg = '验证码不能为空';
error($("#yzmchk"),errorMsg);
}
}else{
$("#register-form").submit();
}
}
$("#sub").click(function(){
formsub();
});显示效果：
有栏目为空时点击提交按钮
注册以及发送邮件：
使用了Zend Framework( 1.11.11 )中的zend_email组件。Zend Framework的下载地址是：https://packages.zendframework.com/releases/ZendFramework-1.11.11/ZendFramework-1.11.11.zip。在Zend Framework根目录下library路径下，剪切Zend文件至服务器下，在注册页面中引入Zend/Mail/Transport/Smtp.php和Zend/Mail.php两个文件。
当点击提交按钮时，表单将数据提交至register_chk.php，然后页面在当前页跳转至register_back.html，通知用户注册结果并且进邮箱激活。
验证邮箱的地址参数使用用户名和一个随机生成的key。
register_chk.php:
<?php
include_once 'conn/conn.php';
include_once 'Zend/Mail/Transport/Smtp.php';
include_once 'Zend/Mail.php';
//激活key,生成的随机数
$key = md5(rand());
//先写入数据库，再发邮件
//写入数据库
//判断是否开启magic_quotes_gpc
if(get_magic_quotes_gpc()){
$postuname = $_POST['uname'];
$postupwd = $_POST['upwd'];
$postuemail = $_POST['uemail'];
}else{
$postuname = addslashes($_POST['uname']);
$postupwd = addslashes($_POST['upwd']);
$postuemail = addslashes($_POST['uemail']);
}
function check_input($value){
// 如果不是数字则加引号
if (!is_numeric($value)){
$value = mysql_real_escape_string($value);
}
return $value;
}
$postuname = check_input($postuname);
$postupwd = check_input($postupwd);
$postuemail = check_input($postuemail);
$sql = "insert into user(uname,upwd,uemail,activekey)values('".trim($postuname)."','".md5(trim($postupwd))."','".trim($postuemail)."','".$key."')";
$num = $conne->uidRst($sql);
if($num == 1){
//插入成功时发送邮件
//用户激活链接
$url = 'http://'.$_SERVER['HTTP_HOST'].'/php/myLogin/activation.php';
//urlencode函数转换url中的中文编码
//带反斜杠
$url.= '?name='.urlencode(trim($postuname)).'&k='.$key;
//定义登录使用的邮箱
$envelope = 'dee1566@126.com';
//激活邮件的主题和正文
$subject = '激活您的帐号';
$mailbody = '注册成功，<a href="'.$url.'" target="_blank">请点击此处激活帐号</a>';
//发送邮件
//SMTP验证参数
$config = array(
'auth'=>'login',
'port' => 25,
'username'=>'dee1566@126.com',
'password'=>'你的密码'
);
//实例化验证的对象,使用gmail smtp服务器
$transport = new Zend_Mail_Transport_Smtp('smtp.126.com',$config);
$mail = new Zend_Mail('utf-8');
$mail->addTo($_POST['uemail'],'获取用户注册激活链接');
$mail->setFrom($envelope,'发件人');
$mail->setSubject($subject);
$mail->setBodyHtml($mailbody);
$mail->send($transport);
echo "<script>self.location=\"templets/register_back.html\";</script>";
}else{
echo "<script>self.location=\"templets/register_back.html?error=1\";</script>";
}
?>邮箱中收取的邮件截图：
然后点击邮箱中的链接进行激活，把数据库中的active设置为1。
activation.php:
<?php
session_start();
header('Content-type:text/html;charset=utf-8');
include_once 'conn/conn.php';
$table = "user";
if(!empty($_GET['name']) && !is_null($_GET['name'])){
//urlencode会对字符串进行转义。所以这里要进行处理
if(get_magic_quotes_gpc()){
$getname = stripslashes(urldecode($_GET['name']));
}else{
$getname = urldecode($_GET['name']);
}
//urldecode反转url中的中文编码
$sql = "select * from ".$table." where uname='".$getname."' and activekey='".$_GET['k']."'";
$num = $conne->getRowsNum($sql);
if($num>0){
$rs = $conne->getRowsRst($sql);
//此时数据库里的字符串是不会带反斜杠的
//因此要为下面的SQL语句加上反斜杠
$rsname = addslashes($rs['uname']);
$upnum = $conne->uidRst("update ".$table." set active = 1 where uname = '".$rsname."' and activekey = '".$rs['activekey']."'");
if($upnum>0){
$_SESSION['name'] = urldecode($getname);
echo "<script>alert('您已成功激活');window.location.href='main.php';</script>";
}else{
echo "<script>alert('您已经激活过了');window.location.href='main.php';</script>";
}
}else{
echo "<script>alert('激活失败');window.location.href='templets/register.html';</script>";
}
}
?>关于注册成功后的邮件页和跳转页，这里不做了。
关于数据库防注入的几种方式magic_quote_gpc，addslashes/stripslashes，mysql_real_eascpae_string，我做了一张表格
附
数据库设计：
user表
create table user (id int primary key auto_increment, uname varchar(14) not null default '', upwd char(32) not null default '', uemail varchar(50) not null default '', active tinyint(4) default '0', activekey char(32) not null defalut '')engine=innodb default charset=utf8
说明：md5的长度是32。
模块的目录结构如下：
ROOT:
