I have an ACF field “DeliverySpeed” attached to Products with the values ‘Fast’ and ‘Slow’
I am trying to update this field to change to value ‘Slow’ automatically every time the product stock is zero or less (product on backorder)
I have managed to come up to this code so far however it is not doing it and I can’t find out what seems to be wrong:
add_action( 'woocommerce_payment_complete', 'update_product_custom_field_after_reduced_stock_levels', 20, 2 );
add_action( 'woocommerce_order_status_completed', 'update_product_custom_field_after_reduced_stock_levels', 20, 2 );
add_action( 'woocommerce_order_status_processing', 'update_product_custom_field_after_reduced_stock_levels', 20, 2 );
add_action( 'woocommerce_order_status_on-hold', 'update_product_custom_field_after_reduced_stock_levels', 20, 2 );
function update_product_custom_field_( $order_id, $order = '' ) {
// Continue only when order has reduced product stock levels
if ( wc_string_to_bool( get_post_meta( $order_id, '_order_stock_reduced', true ) ) )
return $order_id; // Exit
if( ! $order || ! is_a( $order, 'WC_Order') ) {
$order = wc_get_order( $order_id ); // Get the WC_Order object if it's empty
}
$field_key = 'deliveryspeed';
// Loop through order items
foreach ( $order->get_items() as $item ) {
$product = $cart_item['data'];
$product_id = $product->get_id();
$stock_qty = $product->get_stock_quantity();
$field_value = get_field( $field_key, $product_id ); // Get ACF field value
if ( $stock_qty <= 0 && $field_value === 'Fast' ) {
update_field( $field_key, 'Slow', $product_id );
}
elseif ( $stock_qty > 0 && $field_value === 'Slow' ) {
update_field( $field_key, 'Fast', $product_id );
}
}
}
Thank you in advance for the attention and advice.
