Question

I just started with facebook app development.

Problem is that require statement is not working.Even i tried 2 different simple php scripts with include & require statements,It is not locally on wamp server correctly but not as facebook app.

What should i do to get this done??
Code:

<?php
require 'facebook-php-sdk/src/facebook.php';

$facebook = new Facebook(array(
'appId'  => 'YOUR_APP_ID',
'secret' => 'YOUR_APP_SECRET',
));

// Get User ID
$user = $facebook->getUser();
echo "your id id".$user;
?>

It is only printing your id is.Even facebook.php and other files are at right place.

Answer 1

require throws an error if the file can not be found/accessed. If you don’t see anything like that, first make sure you’ve set up error_reporting and display_errors in your PHP development environment right. If still no messages appear, than there is no real problem with embedding the SDK; more likely getUser just returns null or false, and so you just don’t see anything when echo-ing it. Please use var_dump in cases like this, it’ll tell you exactly what type and value a variable really has.

These are absolute basics of PHP debugging – please get a little more used to this, maybe work through some tutorials on the matter, before continuing developing PHP apps for Facebook.
