I'm working on a plugin that runs a function when a post is published with this code:
add_action('publish_post', 'tt_auto_tweet', 99);
How can I display a message below the yellow "Post published" text after this action is run?
I see in /wp-admin/edit-form-advanced.php the code that prints anything sent through an HTTP GET request: if (isset($_GET['message'])). I need to know how to go about sending this request on the page shown after a post is published.
