ACF relationship fields & Polylang

ACF has changed the way they get their posts in 5.2.X. It may be because of polylang/frontend/frontend-auto-translate.php; PLL_Frontend_Auto_Translate->pre_get_posts($query); Since the new method for ACF relies on pre_get_posts.

I am ready to launch a multilingual site with PolyLang and ACF in two weeks. I would love to work towards a solution for this.

BTW, @chouby, thank-you for a great product.

Hi,

I’m having similar problems, when editing a post in another language than whats active in the admin bar. ACF post objects, relationship, page link fields are empty (the values).

I’m trying a workaround on a dev site, with a custom pre get post filter in functions.php:

add_action( 'pre_get_posts', function( $query ) {

	if ( is_admin() ) {
		global $pagenow;

		if ( ( 	'post.php' === $pagenow ||
				'edit-tags.php' === $pagenow
			)
			&& isset( $query->query['post__in'] )
			&& isset( $query->query['post_type'] ) ) {

			// set empty lang
			$query->set( 'lang', '' );
		}
	}

	return $query;
});

But this doesn’t feel like a robust solution… I’m having the same problems with the post 2 post plugin for example.

@chouby, maybe you could give som feedback on this subject?

Edit: I’m using WP 4.2.2, Polylang 1.7.6, ACF 5.2.6
