I'm trying to add Google Analytics link tagging variables to my URLs before Twitter Tools tweets them out. This is what I'm trying to achieve:
http://example.com/?utm_source=twitter&utm_medium=twitter&utm_campaign=EXAMPLE-POST-SLUG
So, I've got this bit of code:
function ses_url_tagger($url) {
// get the post slug
$post_data = get_post($post->ID, ARRAY_A);
$slug = $post_data['post_name'];
if (stristr($url,'?')) {
// URL already has query args, tag on the end
$ses_url = $url . '&';
} else {
// URL doesn't have query args, tag on the end
$ses_url = $url . '?';
}
// append slug to URL
$ses_url = $ses_url . 'utm_source=twitter&utm_medium=twitter&utm_campaign=' . $slug;
return $ses_url;
}
add_filter('tweet_blog_post_url', 'ses_url_tagger');This is not working and I guess it's because the $post_data variable is not available. How do I fix this? Thanks!
