Woodmart widget stock status AND instead of OR

Hi,

I am using the Woodmart stock status widget.
When a user selects both “in stock” and “on backorder” it shows no results.

I guess because the filter works with AND value.

How can I change this to OR so when both are selected, the “in stock” and the “on backorder” will be shown?

Hello,

Try to add the following PHP code snippet to the child theme functions.php file to do this

add_action( 'init', 'wd_update_product_query' );

function wd_update_product_query() {
	if ( class_exists('WOODMART_Stock_Status' ) ) {
		remove_action( 'woocommerce_product_query', array( 'WOODMART_Stock_Status', 'show_in_stock_products' ) );
	}

	add_action( 'woocommerce_product_query', function ( $query ) {
		$current_stock_status = isset( $_GET['stock_status'] ) ? explode( ',', $_GET['stock_status'] ) : array(); //phpcs:ignore

		if ( in_array( 'instock', $current_stock_status, true ) || in_array( 'onbackorder', $current_stock_status, true ) ) {
			$meta_query = array(
				'relation' => 'OR',
			);

			if ( in_array( 'instock', $current_stock_status, true ) ) {
				$meta_query[] = array(
					'key'     => '_stock_status',
					'value'   => 'instock',
					'compare' => '=',
				);
			}

			if ( in_array( 'onbackorder', $current_stock_status, true ) ) {
				$meta_query[] = array(
					'key'     => '_stock_status',
					'value'   => 'onbackorder',
					'compare' => '=',
				);
			}

			$query->set( 'meta_query', array_merge( WC()->query->get_meta_query(), $meta_query ) );
		}
	} );

Kind Regards
