Followup question about sorting by category

Hi, I have a followup question on a closed ticket (#624419) and was hoping you could help. My client wants to have a link that sorts by TWO categories… the code you supplied works perfectly for one category, which is copied below. The specific link example you provided was http://mysite.com/linktopage/?msort=engineering

Is there a way to sort by department and a location keyword? Like, engineering AND india? Thanks so much!

Add this in the functions.php file:
// auto trigger
add_action(‘wp_footer’, ‘ava_custom_script’);
function ava_custom_script() {
?>
<script>
(function($){
function getQueryParams(qs) {
qs = qs.split(“+”).join(” “);
var params = {},
tokens,
re = /[?&]?([^=]+)=([^&]*)/g;

while (tokens = re.exec(qs)) {
params[decodeURIComponent(tokens[1])]
= decodeURIComponent(tokens[2]);
}

return params;
}

var $_GET = getQueryParams(document.location.search);

$(window).load(function() {
switch($_GET[‘msort’]) {
case ‘engineering’:
$(‘.engineering_sort_button’).trigger(‘click’);
break;
case ‘marketing’:
$(‘.marketing_sort_button’).trigger(‘click’);
break;
case ‘operations’:
$(‘.operations_sort_button’).trigger(‘click’);
break;
case ‘sales’:
$(‘.sales_sort_button’).trigger(‘click’);
break;
}
});
})(jQuery);
</script>
<?php
}
The icon link should look like this:
