WooCommerce: Get “Trending” Products

There is a way to display the WooCommerce bestsellers via shortcode / block, but there is no way to calculate the bestsellers – say – from the last 7 days i.e. a list of “trending” products over the last N days.

The function below gives you a way to loop through the latest orders and fill an array with the top 10 products – you can then pass this list of IDs to a shortcode to display them wherever you wish. Enjoy!

PHP Snippet: Get WooCommerce Best Sellers From Last N Days

The function below can be customized as follows:

1. change ‘-7 days’ to whatever time length you require e.g. ‘-2 weeks’, ‘-3 months’ etc.
2. change the “$trending, 0, 10” line to define the number of products you want e.g. “$trending, 0, 3” to get only 3

function bbloomer_product_sold_last_n_days() {
	$all_orders = wc_get_orders(
		array(
			'limit' => -1,
			'status' => array_map( 'wc_get_order_status_name', wc_get_is_paid_statuses() ),
			'date_after' => date( 'Y-m-d', strtotime( '-7 days' ) ),
			'return' => 'ids',
		)
	);
	$trending = array();
	foreach ( $all_orders as $all_order ) {
		$order = wc_get_order( $all_order );
		$items = $order->get_items();
		foreach ( $items as $item ) {
			$product_id = $item->get_product_id();
			if ( ! $product_id ) continue;
			$trending[$product_id] = $trending[$product_id] ? (int) $trending[$product_id] + $item['qty'] : $item['qty'];
		}
	}
	arsort( $trending, SORT_NUMERIC );
	return array_keys( array_slice( $trending, 0, 10, true ) );
}

/* 

Once you have the function active, you can then use a WooCommerce shortcode to display products e.g.:

echo do_shortcode( '[products ids="' . bbloomer_product_sold_last_n_days() . '"]' );

*/

Where to add custom code?

You should place custom PHP in functions.php and custom CSS in style.css of your child theme: where to place WooCommerce customization?

This code still works, unless you report otherwise. To exclude conflicts, temporarily switch to the Storefront theme, disable all plugins except WooCommerce, and test the snippet again: WooCommerce troubleshooting 101
