I am working on login using FB id feature for my application and started with downloading the SDK for FB connect from GITHUB (facebook-php-sdk-master).
Within the application it has two examples 1) For Javascript api and 2) For PHP api.
I want to use the PHP SDK to neglect the javascript disable feature in users website.
Now I entered my applications
$facebook = new Facebook(array(
'appId' => 'deliberately blank',
'secret' => '',
));
I logged in to facebook to check if its working and it always returns 0 even if the user logs in.
I just tried to print the user variable
$user = $facebook->getUser();
print_r($user);
I checked the app settings and I have them correctly set for domain,URL and Canvas URL.I have also disabled the sandbox mode for it.
Is this an issue with the plugin as the session is not captured or I am doing something wrong here?
Anyone worked on or faced similar issue please share your insights as I am stuck and I tried to print the session data using $_SESSION which returns an array which has
Array ( [fb_117096311791424_state] => 5faba08750cd6456hbf27580df3b371 )
But I don't get the user info.Is there any other way to achieve it?Any alternative API etc?
