WooCommerce - how to retrieve current orderby/sorting selection? - wordpress

Question

I need to retrieve the current order of products (as ids) on the shop page for further use. Sorting is done via the standard dropdown (date, price: low to high, price: high to low).
Using $orderby, I can manage this for date and price ASC. But the value of $orderby is the same for price ASC and DESC. How can I correctly retrieve the current value for each sorting option?
if ($orderby == 'date ID') {
$ordertype = 'date';
$meta = '';
$order = 'desc';
}
elseif ($orderby == 'price') {
$ordertype = 'meta_value_num';
$meta = '_price';
$order = 'asc';
}
$query = new WC_Product_Query( array(
'limit' => -1,
'orderby' => $ordertype,
'meta_key' => $meta,
'order' => $order,
'return' => 'ids',
) );
$products = $query->get_products();
print_r($products);

I think your standard dropdown needs to be in this order.
HTML
<select>
<option value="date">Date</option>
<option value="low_to_high">Low to High</option>
<option value="high_to_low">High to Low</option>
</select>
and based on selection your condition will be.
PHP
<?php
if ($orderby == 'low_to_high') {
$ordertype = 'meta_value_num';
$meta = '_price';
$order = 'asc';
}elseif ($orderby == 'high_to_low') {
$ordertype = 'meta_value_num';
$meta = '_price';
$order = 'desc';
}else{
$ordertype = 'date';
$meta = '';
$order = 'desc';
}
$query = new WC_Product_Query( array(
'limit' => -1,
'orderby' => $ordertype,
'meta_key' => $meta,
'order' => $order,
'return' => 'ids',
) );
$products = $query->get_products();
print_r($products);
?>
