I am currently working on a project including the Facebook SDK. I already made it to Login/Logout myself using the javascript code.
I'm using an AJAX POST request to save the userID and the name from the response in a Session.
The problem here is, that I actually have to reload the page twice, the first time to get the POST parameters and save them into a $_SESSION. The second refresh is needed to load the Session.
Is there a clean way to avoid that?
javascript: $.post( "login.php", { id:userID, name:response.name } );
login.php:
$_SESSION['name'] = $_POST['name'];
$_SESSION['userID'] = $_POST['id'];
I appreciate every kind of help. Thank you.
edit: I would like to give the user who logged in with facebook additional oppurtunities on my website. The only way I know how to do this is with a Session in PHP. Whenever he logged in I created a Session who said that a person is logged in.
Now I have to do the same with a facebook login. It worked local with the PHP SDK already, but the webspace does not support that kind of SDK. That is why I have to dodge to the javascript one. Is there another way to make sure a person is logged?
You are using AJAX,
So you can avoid reloading of Page,
<?php
session_start();
if (isset($_GET['name'])) {$_SESSION['name'] = $_GET['name'];}
if (isset($_GET['userID'])) {$_SESSION['userID'] = $_GET['userID'];}
if(isset ($_POST['name'] ) && isset ($_POST['userID'])){
$_SESSION['name']= $_POST['name'];
$_SESSION['userID']= $_POST['userID'];
}else{
$_SESSION['userID'] = 0;
}
?>
and javascript code is:
$.post( "/login.php", { id:userID, name:response.name } );
