jquery.validate表单验证完整案例
功能一：用户名检查是否存在(ajax、php方法取得)
功能二：自定义验证
1、字符串检查:只能包括中文字、英文字母、数字和下划线；
简单两数字相加的验证码验证
index.php代码
<?php
//验证码 PHP获取随机数
$n1= rand(1, 9);//生成1-9随机数
$n2=rand(9, 1);//生成9-1随机数
$n=$n1+$n2;
//echo randomkeys(4);
?>

user_reg.php代码 (检查用户名是否存在)
接收ajax传递过来的值，php判断自己写
<?php
header("Content-type: text/html;charset=utf-8");
include("sunland_config.php");
$action=trim($_REQUEST['action']);
$username=trim($_REQUEST['username']);
if( $action == 'ck_user' ){
//判定用户名是否存在
$sqlmm2_user="select t1,id from userinfo where t1='".$username."'";
$connmm2_user=mysql_query($sqlmm2_user);
$num_rows = mysql_num_rows($connmm2_user);
if( $num_rows != '' ){
exit( "false" ); //用户名已存在
}else{
exit( "true" ); //用户名不存在，验证通过，输出“true”，并结束程序
}
mysql_close();
}
?>
03.php代码(提交表单，把数据插入数据库)
插入数据库PHP自己写，这里只是做一个简单判断，返回一个值，知道是否注册成功
<?php
header('Content-type:text/json;charset=utf-8');
$username=$_POST['username'];
$password=$_POST['password'];
//也可以在成功插入数据库后再赋值success 在这里不具体写出来，只是做一个简单判断后赋值
if($username=="" || $password==""){
$su="";
}else{
$su="success";//给su赋值“success”;
}
$data='{su:"' . $su .'"}';//只返回su变量值来判断是否注册成功，其它值不返回
//$data='{username:"' . $username . '",password:"' . $password .'",su:"' . $su .'"}';//所有值都返回
echo json_encode($data);
?>
