Multisite

Hi,

I wanted to use this on multisite for logged in users only. Made the following changes

/app/entities/user/userrepository.php

public function getFavorites($user_id = null)
	{
		$saveType = $this->settings_repo->saveType();

		if ( is_user_logged_in() ) {
			$user_id = ( isset($user_id) ) ? $user_id : get_current_user_id();
			$key = (is_multisite() ? 'simplefavorites_' . get_current_blog_id() : 'simplefavorites');
			$favorites = get_user_meta($user_id, $key);

			if ( empty($favorites) ) return array();
			return $favorites[0];
		}
		$favorites = ( $saveType == 'cookie' ) ? $this->getCookieFavorites() : $this->getSessionFavorites();
		return $favorites;
	}

And

app/entities/favorite/syncuserfavorite.php

	public function updateUserMeta($favorites)
	{
		if ( !is_user_logged_in() ) return false;
		$key = (is_multisite() ? 'simplefavorites_' . get_current_blog_id() : 'simplefavorites');
		return update_user_meta( get_current_user_id(), $key, $this->array_flatten($favorites) );

	}

By adding a site_id $key to the user meta I have the functionality I want, could you support this in a future release?
