trying to use use facebook-php-sdk library to retrive facebook posts

Question

I am trying to pull facebook posts onto my site so that I can save and display it in my own format. I am trying to use the facebook-php-sdk library, found on the Facebook Developer pages. I used the following code after I required the library:

$facebook = new Facebook(array(
'appId'  => 'MY APP ID',
'secret' => 'MY APP SECRET',
));

// Get User ID
$user = $facebook->getUser();
print_r($facebook);
print_r($user);

The print_r into $facebook showed me a full facebook object, so I know its being created properly.

 object(Facebook)#325 (9) { ["sharedSessionID":protected]=> NULL ["appId":protected]=> string(15) "[MYAPPID]" ["appSecret":protected]=> string(32) "[MYAPPSECRET]" ["user":protected]=> int(0) ["signedRequest":protected]=> NULL ["state":protected]=> NULL ["accessToken":protected]=> string(48) "[MYAPPID]|[MYAPPSECRET]" ["fileUploadSupport":protected]=> bool(false) ["trustForwarded":protected]=> bool(false) }

(I took my app id and app secret codes out of the quote above).

However, the print_r into $user displayed

int(0).

What am I missing here?

Answer 1

“What am I missing here?” Authenticating the user. You’re calling getUser(), but until you authenticate, Facebook doesn’t know which user to get details for. I’m also unsure why you’ve missed it, as it’s the example on the GitHub repo for the PHP SDK.
