I am trying to make a post sticky on publish or update based on a custom field. I use the code below but it doesn't work.
What am I doing wrong?
function stick_post_on_save( $post_id ) {
$ed_plus = get_post_meta( $post_id, 'ed_plus', true );
if ( $ed_plus ) {
stick_post($post_id);
}
}
add_action( 'save_post', 'stick_post_on_save' );
