Print additional fields?

The plugin I am using is called Purchase Orders for WooCommerce (https://wordpress.org/plugins/purchase-orders-for-woocommerce/). I reached out to them a few days ago regarding the field information. When they respond, I’ll let you know. Thanks!

Hi @kenil802

The plugin author says that the field is called “_purchase_order_number” and is part of the regular post meta from the order.

From a search I did, I found this code which I thought was supposed to display the purchase order number, but it is not.

function add_purchase_order_to_invoice_slip( $fields, $order ) {
    $new_fields = array();
        
    if( get_post_meta( $order->id, '_purchase_order_number', true ) ) {
        $new_fields['_purchase_order_number'] = array( 
            'label' => 'Purchase Order Number',
            'value' => get_post_meta( $order->id, '_purchase_order_number', true )
        );
    }
    return array_merge( $fields, $new_fields );
}

add_filter( 'wcdn_order_info_fields', ' add_purchase_order_to_invoice_slip', 10, 2 );

That did it! (That and removing an extraneous space from add_filter that was preventing the entire block from loading). Thank you so much!
