EDIT:
Post_date have this format : Y-m-d H:i

Answer 1

You are comparing POST_DATE which is a datetime with CURRENT_DATE which is a Date , it won’t give any result.

you can try the following SQL

$sql = 'SELECT * FROM wp_posts WHERE  post_status = "publish" AND DATE(post_date) = CURRENT_DATE  ORDER BY post_date DESC LIMIT 15';

This will convert the post_date to only date before comparing with current date.
