Hi,
Sure! It is possible to do programmatically via the Frontend Filters API.
It highly depends on the exact scenario, but this is the starter code you are looking for:
add_filter('asp_pre_get_front_filters', 'asp_change_a_filter', 10, 2);
function asp_change_a_filter($filters, $type) {
if ($type == 'taxonomy') {
$selected = array(
// page id => selected category ID,
1 => 123,
2 => 12344
);
foreach ($filters as $k => &$filter) {
// Go through the filter items via a loop
foreach ($filter->get() as $kk => $item) {
// Should this be selected?
if ( isset($selected[get_the_ID()]) && $item->id == $selected[get_the_ID()] ) {
$filter->attr($kk, 'selected', true, true);
} else {
// Unselect the rest
$filter->attr($kk, 'selected', false, true);
}
}
}
}
return $filters;
}Unfortunately I could not test this right now, but should be very close to a possible solution.
