I want to automatically add a specific attribute value (which was previously set up) to ordered products when the order is placed and has "on-hold" status.

I sell unique products and I have set up the "STOCK" attribute and the "Out Of Stock" (out-of-stock) value.

When an order is placed and has "on-hold" status, I want to automatically change the featured status of the ordered products and also to add the out-of-stock attribute value to it.

The featured part is done and works, but I can't figure out how to add a specific attribute value to the products.

Here's my code:

add_action('woocommerce_order_status_on-hold', 'order_status_on_hold_update_products', 20, 2);



function order_status_on_hold_update_products( $order_id, $order ) {

  foreach ( $order->get_items() as $item_id => $item ) {

    $product = $item->get_product();

    $product->set_featured(true);

    $product->set_attributes(???); // I don't know if and how set_attributes() should be used

    $product->save();

}

To set stock status "Out of Stock" you will use the WC_Product method set_stock_status() this way:

 $product->set_stock_status('outofstock'); // Or "instock"

 $product->save();

To set a product attribute term in your hooked function (work for variable products too):

add_action('woocommerce_order_status_on-hold', 'order_status_on_hold_update_products', 20, 2);

function order_status_on_hold_update_products( $order_id, $order ) {

    foreach ( $order->get_items() as $item_id => $item ) {

        $product = $item->get_product();



        // Handling variable products

        $_product = $product->is_type('variation') ? wc_get_product( $item->get_product_id() ) : $product;



        $_product->set_featured( true );



        // Your product attribute settings

        $taxonomy   = 'pa_stock'; // The taxonomy

        $term_name  = "Out Of Stock"; // The term



        $attributes = (array) $_product->get_attributes();

        $term_id    = get_term_by( 'name', $term_name, $taxonomy )->term_id;



        // 1) If The product attribute is set for the product

        if( array_key_exists( $taxonomy, $attributes ) ) {

            foreach( $attributes as $key => $attribute ){

                if( $key == $taxonomy ){

                    $attribute->set_options( array( $term_id ) );

                    $attributes[$key] = $attribute;

                    break;

                }

            }

            $_product->set_attributes( $attributes );

        }

        // 2. The product attribute is not set for the product

        else {

            $attribute = new WC_Product_Attribute();



            $attribute->set_id( sizeof( $attributes) + 1 );

            $attribute->set_name( $taxonomy );

            $attribute->set_options( array( $term_id ) );

            $attribute->set_position( sizeof( $attributes) + 1 );

            $attribute->set_visible( true );

            $attribute->set_variation( false );

            $attributes = $attribute;



            $_product->set_attributes( $attributes );

        }



        $_product->save();



        // Append the new term in the product

        if( ! has_term( $term_name, $taxonomy, $_product->get_id() ) )

            wp_set_object_terms($_product->get_id(), $term_slug, $taxonomy, true );

    }

}

Code goes in function.php file of your active child theme (or active theme). it should works.
