The "CLEAR FILTERS" link will appear on the filter bar when a sort has been requested but no active filters are in place.

In app/View/Elements/search.ctp we have:

<?php if(!empty($search_params)):?>

but $search_params contains the sort information as well as the search fields. So, when there are no search fields to display, but a sort exists, this will not be empty. Therefore we need a further test around the "CLEAR FILTERS" link.

We can add a “hasFilters” variable that is false, and set it to true after we’ve bypassed the continue statement (approx. lines 69-71):

if(!in_array($key, $search_fields)) {

  continue;

}

Then we can just wrap the #top-search-clear-all-button block with a conditional to only show if hasFilters is true.
