在Wordpress计数器中调用永久链接

Question

I'm using a code i found in the Internet to count Facebook shares, but I'm not able to call the permalink I'm using.

The function:

<?php
$facebook_like_share_count = function ( $url ) {

    $api = file_get_contents( 'http://graph.facebook.com/?id=' . $url );

    $count = json_decode( $api );

    return $count->shares;
};
?>

The call:

<?php echo $facebook_like_share_count( 'http://www.someurl.com' ); ?>

My permalink:

<?php the_job_permalink(); ?>

I tried many ways and none worked.
