});
function loadLog(){
$.ajax({
url: "onlineusers.html",
cache: false,
success: function(html){
$("#online").html(html);
},
});
}
test.php (This is my temporary file to test the Login authentication for FB.. THIS IS WORKING)
<?php
session_start();
require_once("src/facebook.php");
$config = array(
'appId' => '285873338131549',
'secret' => '56b9f71b9fd307a033aeeb725893fc89',
);
$facebook = new Facebook($config);
$user_id = $facebook->getUser();
?>
<?php
if($user_id) {
try {
$user_profile = $facebook->api('/me','GET');
$profile = $user_profile['name'];
$_SESSION['user'] = $profile; //PUT USER TO SESSION
$_SESSION['user_id'] = $user_id;
$line = file_get_contents("onlineusers.html");
$line = trim($line); // removes leading/trailing blank lines
$line = explode("\n", $line);
$line[] = '<tr><td><img src="https://graph.facebook.com/' . $_SESSION['user_id'] . '/picture"width="25"height="25"/></td><td>' . $_SESSION['user'] . '</td><td><a href="http://www.fb.com/' . $_SESSION['user_id'] . '" target="_blank">View Profile</a></td></tr>';
$line = array_unique($line);
$line = implode("\n", $line);
file_put_contents("onlineusers.html", $line);
echo 'OK';
} catch(FacebookApiException $e) {
$login_url = $facebook->getLoginUrl();
echo '<a href="' . $login_url . '">LOGIN</a>';
error_log($e->getType());
error_log($e->getMessage());
}
} else {
$login_url = $facebook->getLoginUrl();
echo '<a href="' . $login_url . '">LOGIN</a>';
}
echo "<a href='logout.php'>Logout</a>";
?>
What it does is, it simple insert the picture and name of the user in a flat html file.. http://www.barkadafm.org/onlineusers/index.php
Now, my problem is,.
I dont know how to delete the pic and name if a user logs out or disconnect..
Example, my name is Name5 and i will connect / login using http://www.barkadafm.org/onlineusers/test.php
