There is a great tutorial on how to interact with the Graph API here: http://johndoesdesign.com/blog/2011/php/adding-a-facebook-news-status-feed-to-a-website/
My personal approach is to wrap that code in a function and then echo that function in a theme´s template-file.
Recipe:
1. get an access token for the page
2. create a function in your theme´s functions.php:
function display_facebook_info() {
$page_id = 'YOUR_PAGE_ID';
$access_token = 'YOUR_ACCESS_TOKEN';
//Get the JSON
$json_object = @file_get_contents('https://graph.facebook.com/' . $page_id .
'/posts?access_token=' . $access_token);
//Interpret data
$fbdata = json_decode($json_object);
foreach ($fbdata->data as $post )
{
$posts .= '<p><a href="' . $post->link . '">' . $post->story . '</a></p>';
$posts .= '<p><a href="' . $post->link . '">' . $post->message . '</a></p>';
$posts .= '<p>' . $post->description . '</p>';
$posts .= '<br />';
}
//Display the posts
echo $posts;
}
3. Display the posts in your template-file:
<?php echo display_facebook_info(); ?>
