Question

I am working on a web site with login registration functionality.I have implemented the login registration part with reference and forum help,but now I am facing problem with the PHP session.This is my ajax form submit:

   $.ajax({
                    type: "POST",
                    url: "userLogin.php",
                    data: "eid="+eid+"&pwd="+pwd+"&rememberme="+remember,
                    dataType: "html",
                    success: function(msg){
                        if($.trim(msg)!="error")
                        {
                            $("#user_status", window.parent.document).html("Welcome "+msg+"&nbsp;&nbsp;|&nbsp;&nbsp;<a href='forum/logout.php'>Logout</a>");

                            if(window.parent.document.getElementById('post_user_name'))
                                $("#post_user_name", window.parent.document).html("<strong style='color:#333333;'>"+msg+"</strong>");

                            parent.$.fancybox.close();
                        }
                        else{
                            $('#error_common').html("Invalid ID or password.Please try again");
                            $('#error_common').show();
                            return false;
                        }
                    }
                });

This is the PHP code:

             if(isset($_POST['eid']) && isset($_POST['pwd']))
          {     
                $userObj = new Model_Users();
                $username= return_fetched_value($_POST['eid']);
                $password= md5(return_fetched_value($_POST['pwd']));
                $getUserDetails = $userObj->getUserValueByUserNameAndPassword($username,$password);
                /*print_r($getUserDetails);
                exit;*/

                if(count($getUserDetails)>0)
                {   

                    $_SESSION['username'] = $getUserDetails['uname'];
                    $displayUser=$getUserDetails['uname'];  
                    echo $displayUser;

                }
                else
                {
                    //echo "entered here";  
                    echo "error";
                }

          }
          else
          {
            $errorMessage = "You have entered invald username password" ;

          }

Everything works fine,the user logs in and get the username on the login page as here http://www.proptiger.com/,but if I refresh the page the username disappears,but it is still present in the session.I can see it if I do print_r($_SESSION).
The username has been set using the jquery ajax portion.

        $("#user_status", window.parent.document).html("Welcome "+msg+"&nbsp;&nbsp;|&nbsp;&nbsp;<a href='forum/logout.php'>Logout</a>");

Which I think is not persisted,but still there in the session.I am new to jquery ajax and stuck at this.Any constructive comments would be helpful.
Thanks

Answer 1

This might sound silly but are you sure you’re displaying the username with php on page load or is it just when there’s a login ajax call?

As far as I can tell your code only displays the username after your AJAX call, but there isn’t anything like <?php echo $_SESSION['username']; ?> when you load the page without ajax.

I hope my answer is clear enought, but just to conclude: Make sure you echo the username when someone goes directly into your website and not just on the login action.
