通过隐藏注册表单来显示警报通知

我有两个php文件，一个是寄存器.php其中我有html表单，我使用jquery来验证它。 在过程中.php我有PHP代码将数据插入数据库的注册表表中，如果它用户名不退出。

我想通过在 register.php 中隐藏 HTML 表单来在段落标签或div 标签中显示 alearts。这些阿莱亚特是1. 用户名已存在2. 用户注册成功3. 注册不成功。

请看一程.php这部分

if($show>0)
                {
                die("user exits");
                } 

if($query)
                die("registration successfull");
                else
                die("registration not successful");

我想通过隐藏表单并播放该通知来在注册.php文件上显示这些警报......

这是寄存器.php简而言之的代码。

<script src='jquery-1.9.1.min.js' type="text/javascript"></script>
 <script type="text/javascript" src="jquery.validate.js"></script>
<script >
$(document).ready(function(){
            $("#formjs").validate({
                rules:{
                    fname:{
                        required:true,
                        minlength:5,
                        maxlength:23
                    },
                    lastname:{
                        required:true,
                        minlength:5,
                        maxlength:23
                    },
                  and so onoooooooooooo

   some part of form
</div>
            <form id="formjs" name="formjs" method="post" action="process.php" >
                <p>
                <label for="name">Name *</label>
                <input type="text" name="fname" id="fname" value=""  />
                </p>
                <p>
                <label for="lastnamme">LastName *</label>
                <input type="text" name="lastname" id="lastname"  />
                </p>
                <p>
                <label for="username">Email Address *</label>
                <input type="text" name="username"  id="username" />
                </p>
                <p>

这是过程.php完整的代码...

                if(isset($_POST['username']))
                {
                $ftname=$_POST['fname'];

                include('config.php');
                $Query = mysql_query("SELECT userid from Account where userid = '$username'") or die(mysql_error());
                $show=mysql_num_rows($Query);
                if($show>0)
                {
                die("user name already exits");
                } 
                else 
                {
                $query=mysql_query(" insert into Account (firstname,lastname,gender,bday,byear,bmonth,userid,password,contactno) values 
                            ('$ftname','$lastname','$gender','$bday','$byear','$bmonth','$username','$password','$contact')") or die(mysql_error());
                if($query)
                die("registration sucessfull");
                else
                die("registration not sucessfull");
                //echo "<center>Thank you! You are now a member!</center>";
