Product Item missing

Hi @jennyong,

First of all, apologies for the delay in getting back to you on this.

Are you saying that the fields added with the Gravity Forms Product add-ons plugin are not coming in the Invoice? If yes, I recommend you to use the below mentioned filter to add these fields to the Invoice using their meta keys:

/**
 * Add this code snippet in functions.php file of your currently active theme.
 * An example that adds a 'VAT' and 'Customer Number' field to the end of the list. 
 */
function example_custom_order_fields( $fields, $order ) {
    $new_fields = array();
        
    if( get_post_meta( $order->id, 'your_meta_field_name', true ) ) {
        $new_fields['your_meta_field_name'] = array( 
            'label' => 'VAT',
            'value' => get_post_meta( $order->id, 'your_meta_field_name', true )
        );
    }
    
    if( get_post_meta( $order->id, 'your_meta_field_name', true ) ) {
        $new_fields['your_meta_field_name'] = array( 
            'label' => 'Customer Number',
            'value' => get_post_meta( $order->id, 'your_meta_field_name', true )
        );
    }
    
    return array_merge( $fields, $new_fields );
}
add_filter( 'wcdn_order_info_fields', 'example_custom_order_fields', 10, 2 );

Instead of the VAT ID and Customer number examples in the above snippet you can add your fields added using the Gravity Forms plugin using the meta keys for those fields.

Kind Regards,
Upendra.
