Change Product Order in Woocommerce

Hi there,

I want to display the products I have in Date order rather than the default alphabetical order.

I added this hook to the themes functions but did not do the trick

add_filter(‘woocommerce_get_catalog_ordering_args’, ‘custom_woocommerce_get_catalog_ordering_args’);

function custom_woocommerce_get_catalog_ordering_args( $args ) {
if (isset($_SESSION[‘orderby’])) {
switch ($_SESSION[‘orderby’]) :
case ‘date_asc’ :
$args[‘orderby’] = ‘date’;
$args[‘order’] = ‘asc’;
$args[‘meta_key’] = ”;
break;
case ‘price_desc’ :
$args[‘orderby’] = ‘meta_value_num’;
$args[‘order’] = ‘desc’;
$args[‘meta_key’] = ‘_price’;
break;
case ‘title_desc’ :
$args[‘orderby’] = ‘title’;
$args[‘order’] = ‘desc’;
$args[‘meta_key’] = ”;
break;
endswitch;
}
return $args;
}

add_filter(‘woocommerce_catalog_orderby’, ‘custom_woocommerce_catalog_orderby’);

function custom_woocommerce_catalog_orderby( $sortby ) {
$sortby[‘title_desc’] = ‘Reverse-Alphabetically’;
$sortby[‘price_desc’] = ‘Price (highest to lowest)’;
$sortby[‘date_asc’] = ‘Oldest to newest’;
return $sortby;
}

I would be grateful if someone could point me in the right direction as what did seems to have not worked. Thanks in advance.
