Remove related when using Upsell

Hi @donlee101,

The code below functions correctly when tested using a default theme like Twenty Twenty. If this does not work for your theme that indicates the default WooCommerce action hooks have possibly been changed by the theme your using.

If you search your themes codebase for woocommerce_upsell_display you should be able to locate those and alter the code below as required.

remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_upsell_display', 15 );
remove_action( 'woocommerce_after_single_product_summary', 'woocommerce_output_related_products', 20 );

add_action( 'woocommerce_after_single_product_summary', 'related_upsell_products', 15 );

function related_upsell_products() {
	global $product;

	if ( isset( $product ) && is_product() ) {
		$upsells = version_compare( WC_VERSION, '3.0', '<' ) ? $product->get_upsells() : $product->get_upsell_ids();

		if ( count( $upsells ) > 0 ) {
			woocommerce_upsell_display();
		} else {
			woocommerce_upsell_display();
			woocommerce_output_related_products();
		}
	}
}

I hope this helps.

Thanks
