sending back variable to ajax

[tommie20]

Hi guys,

 

I have a login page where the user can login, the input is being send to php where it checks if the input is in the mysql database. If so i would like to send back the username that is typed in to autofill it in a form completed later on. In code:

 

 $(document).ready(function(){
        $("#username").focus();

        $("#submit").click(function(){
                $.ajax({
                        url: "http://serverip/session.php",
                        cache: false,
                        type: "POST",
                        data:{
                                username: $("#username").val(),
                                password: $("#password").val()
                        },
                        success: function(data){
                                if (data == '1')
                                     
                                     window.location.replace("home.html");
                                     
                                else{
                                        alert("error");
                                }
                        }
                });
        });
}); 

 

PHP:

 

<?php

session_start();

if(!isset($_SESSION['username'])){
        if(isset($_POST['username'])){
                $db = new mysqli("localhost", "root", "", "gegevens");
                $stmt = $db->prepare("SELECT username FROM members WHERE username = ? AND password = ?");
                $stmt->bind_param('ss', htmlentities($_POST['username'], ENT_QUOTES), htmlentities($_POST['password'], ENT_QUOTES));
                $stmt->execute();
                $stmt->store_result();
                
                 if($stmt->num_rows() == 1){
                        $stmt->bind_result($username);
                        $stmt->fetch();
                        $_SESSION['username'] = $username;

                        echo "1";
                        exit;
                }
        }else{
                echo "0";
        }
}
?> 

 

I read in other posts that i could use datatype json to send multiple variables back. But i couldn't get it to work properly.

I would like to send back the username typed in but the '1' has to be send back too.

Thanks,

 

Tom

Why not post the code that isn't working then?

 

It's really as simple as:

 

echo json_encode(array('username' => $username, 'status' => true));

 

In your php, then something like....

 

success: function(data) {
  if (data.status == 1) {
    console.log('You have logged in as ' + data.username);
  } else {
    console.log('Login failed');
  }
}

 

in you Javascript.
