Thanks John – however, a detailed solution came through (which I think you were pointing me towards) from James on [email protected] which does exactly what I want. Code is (to put in [theme]/functions.php) :
function my_acf_load_value( $value, $post_id, $field ) {
$content = apply_filters('the_content',$value);
$content = force_balance_tags( $content );
$content = preg_replace( '#<p>\s*+(<br\s*/*>)?\s*</p>#i', '', $content );
$content = preg_replace( '~\s?<p>(\s| )+</p>\s?~', '', $content );
return $content;
}
add_filter('acf/load_value/type=wysiwyg', 'my_acf_load_value', 10, 3);
No more empty <p> tags in ACF Wysisyg fields!
