I have the same issue, however, I was able to figure out how to get the url to work by modifying the meta_query in functions.php:

$meta_query[] = array( 
	    		relation => 'AND',
	    		array(
	                'key'		=> 'community',
	                'value'		=> $community,
	                'compare'	=> 'IN',
                ),
                array(
	                'key'		=> 'listing_status',
	                'value'		=> $status,
	                'compare'	=> 'IN',
                ),
            );

So, when I visit http://www.website.com/listings/?listing_status=sold&community=cityname, if I have a Listing that is both sold and in cityname, the listing is displayed and my checkboxes show in the sidebar. However, as soon as my URL changes to something like http://www.website.com/listings/?listing_status=sold&community=newcityname (where “newcityname” is not marked as “sold”) I get the following error when where the checkboxes normally show:

Warning: Invalid argument supplied for foreach() in /serverpath/wp-content/themes/themename/archive-listings.php on line 27
(where line 27 is my foreach loop)

Here’s my code:

<?php 
				$field = get_field_object('community');
				$values = isset($_GET['community']) ? explode(',', $_GET['community']) : array();
				
				$field2 = get_field_object('listing_status');
				$values2 = isset($_GET['listing_status']) ? explode(',', $_GET['listing_status']) : array();
				?>
				<ul class="communities">
					<?php foreach( $field['choices'] as $choice_value => $choice_label ): ?>
						<li>
							<input type="checkbox" value="<?php echo $choice_value; ?>" <?php if( in_array($choice_value, $values) ): ?>checked="checked"<?php endif; ?> /> <?php echo $choice_label; ?></li>
						</li>
					<?php endforeach; ?>
				</ul>
				<ul class="status">
					<?php foreach( $field2['choices'] as $choice_value2 => $choice_label2 ): ?>
						<li>
							<input type="checkbox" value="<?php echo $choice_value2; ?>" <?php if( in_array($choice_value2, $values2) ): ?>checked="checked"<?php endif; ?> /> <?php echo $choice_label2; ?></li>
						</li>
					<?php endforeach; ?>
				</ul>

How can I fix this?

Also, how can I do the URL replacement when someone clicks on the checkboxes? I have the below setup which works for one custom field parameter at a time but not both:

<script type="text/javascript">
    //Listing URL Query Change
	(function($) {
		$('.communities').on('change', 'input[type="checkbox"]', function(){
			// vars
			var $ul = $(this).closest('ul'),
				vals = [];

			$ul.find('input:checked').each(function(){

				vals.push( $(this).val() );

			});

			vals = vals.join(",");

			window.location.replace('<?php echo home_url('listings'); ?>?community=' + vals);
		});
		$('.status').on('change', 'input[type="checkbox"]', function(){
			// vars
			var $ul = $(this).closest('ul'),
				vals = [];

			$ul.find('input:checked').each(function(){

				vals.push( $(this).val() );

			});

			vals = vals.join(",");

			window.location.replace('<?php echo home_url('listings'); ?>?listing-status=' + vals);
		});
	})(jQuery);	
</script>

Thanks in advance for any help 🙂
