jquery文件

Next page profile.html i want to retrive value from database...

jquery file

$(document).ready(function(){
    getval();
  
});
function getval()
{
    $.ajax({   
        type:"GET",
        url:"http://localhost/group/php/profileedit.php",
        success: function(result)//,var email,var mobile,var dob

<pre><?php                    
        if(isset($_SESSION['user'])) 
        {
            $uname = $_SESSION['user'];
        }else
        {
            die('Could not connect: ' . mysql_error()); 
        }    
        $link = mysql_connect('localhost','root','');

        if (! $link) 
        {
            die('Could not connect: ' . mysql_error());
        }

        mysql_select_db("groupchat",$link) or die('couldnt able to connect db');      
        $sql = "select fname,lname from users where username = '$uname'";       
        $result = mysql_query($sql,$link);        
        if(! $result)
        {
            die('Could not get data:'. mysql_error());    
        }        
        $row = mysql_fetch_array($result);
        
        echo trim($row['fname']);    
        echo trim($row['lname']);           
        mysql_close($link);      
  ?> 

但是在文本框中它无法追溯价值从会话变量，如它没有在会话中注册，但当我手动给它值，它从数据库成功检索值并填写文本框...





请帮助....建议我...提前谢谢..
