Hello, i testing now ACF. I creating a WP archive with custom field filter by documentation video. http://www.advancedcustomfields.com/resources/creating-wp-archive-custom-field-filter/. And it`s all working.

But now i have little problem, how to make a second parameter?

Ex: At documentation we use only one checkbox bedrooms, but i want add livingrooms(or bathrooms).

Checkbox Filter(archive-houses.php) must be like

bedrooms 1 | 2 | 3
bathrooms 1 | 2 | 3

I added bathroom, and now can fileter by http://www.website/blabla/?badrooms=1,2&bathrooms=1.

add_action('pre_get_posts', 'my_pre_get_posts');

function my_pre_get_posts( $query )
{
	// validate
	if( is_admin() )
	{
		return;
	}

	if( !$query->is_main_query() )
	{
		return;
	}

	// get original meta query
	$meta_query = $query->get('meta_query');

        // allow the url to alter the query
        // eg: http://www.website.com/events?location=melbourne
        // eg: http://www.website.com/events?location=sydney
        if(( !empty($_GET['bedrooms']) ) && ( !empty($_GET['bathrooms']) ))
        {
        	$bedrooms = explode(',', $_GET['bedrooms']);
			$bathrooms = explode(',', $_GET['bathrooms']);

        	//Add our meta query to the original meta queries
	    	$meta_query[] = array(
                'key'		=> 'bedrooms',
                'value'		=> $bedrooms,
                'compare'	=> 'IN',
            );
			$meta_query[] = array(
                'key'		=> 'bathrooms',
                'value'		=> $bathrooms,
                'compare'	=> 'IN',
            );
        }

	// update the meta query args
	$query->set('meta_query', $meta_query);

	// always return
	return;

}

Now i found one more problem. If badrooms=1 and bathroom=3, but we have no bathroom=3 at badroom=1. We have error.
