Print shipping tracking on Invoice and order details

Hi @cfm168,

It really depends on how this data is saved in WooCommerce.
Displaying Custom Fields

So if you know the fields (let’s assume for the sake of this conversation: custom_field_1 & custom_field_2), you could insert them after the order details area as follows:

add_action( 'wpo_wcpdf_after_order_details', 'wpo_wcpdf_tracking_and_date', 10, 2 );
function wpo_wcpdf_tracking_and_date ($template_type, $order) {
    if ($template_type == 'invoice') {
        $document = wcpdf_get_document( $template_type, $order );
        ?>      
        <div class="shipping-tracking-date">
            <b>Tracking Number:</b>
            <div><?php $document->custom_field('custom_field_1'); ?></div>
            <b>Shipping Date:</b>
            <div><?php $document->custom_field('custom_field_2'); ?></div>
        </div>
        <?php
    }
}

Hi @dpeyou,

The shipping tracking plugin author provided me a long snippet.
1) Should I put the snippet after the code you provided above?
2) The author advised me: “where you have to replace the $order_id with the variable that holds the current order id. The $shipping_traking_num and the $dispatch_date will hold the data you need to print inside the invoice.”, How should I do?

Please advise. Thanks in advance!

@cfm168 if you share the snippet that was provided to you we can answer the questions in 2).

Sure, will send to you via email. I think I have your email. Thanks!

If you can post it here, it’s even better, that way other people with the same issue will benefit from it too!

Here is the snippet:

global $wcst_tracking_info_displayer, $wcst_time_model;

$tracking_meta = $wcst_tracking_info_displayer->get_order_meta($order_id);
$shipping_traking_num = $tracking_meta[‘_wcst_order_trackno’][0];

$dispatch_date = isset($tracking_meta[‘_wcst_order_dispatch_date’][0]) ? $tracking_meta[‘_wcst_order_dispatch_date’][0] : __( ‘N/A’, ‘woocommerce’ ) ;
$dispatch_date = $wcst_time_model->format_data($dispatch_date);

(it should look like this: https://www.dropbox.com/s/83i17tlxwsxv38b/wcst_snippet.jpg?dl=0 )

Hi @pomegranate,
Any updates for me? Thanks in advance!

Thanks for the heads up! With a small modification you can use that code directly in the form that @dpeyou formatted it for you earlier. Can you try this?

add_action( 'wpo_wcpdf_after_order_details', 'wpo_wcpdf_tracking_and_date', 10, 2 );
function wpo_wcpdf_tracking_and_date ($template_type, $order) {
	if ($template_type == 'invoice') {
		global $wcst_tracking_info_displayer, $wcst_time_model;

		$tracking_meta = $wcst_tracking_info_displayer->get_order_meta( $order->get_id() );
		$shipping_traking_num = $tracking_meta['_wcst_order_trackno'][0];

		$dispatch_date = isset($tracking_meta['_wcst_order_dispatch_date'][0]) ? $tracking_meta['_wcst_order_dispatch_date'][0] : __( 'N/A', 'woocommerce' ) ;
		$dispatch_date = $wcst_time_model->format_data($dispatch_date);
		?>
		<div class="shipping-tracking-date">
			<b>Tracking Number:</b>
			<div><?php echo $shipping_traking_num; ?></div>
			<b>Shipping Date:</b>
			<div><?php $dispatch_date; ?></div>
		</div>
		<?php
	}
}

Hi @pomegranate,

Where should I put these code in? Should I put it in functions.php under my child theme?

Hello @cfm168,

Please read this guide to learn how to work with code snippets (actions/filters) or functions.php: How to use filters

Hi @pomegranate,

The code you provided are not working and get the following error when I try to download the invoice from admin:

Fatal error: Call to undefined method WCST_Tracking_info_displayer::get_order_meta()

I added the code on the child theme. It also causes the Invoice to become not downloadable but view only. Delete the code every thing back to good normal.

I have sent the error details to your email. Please check and help.

Thanks in advance!

@cfm168 This part of the code is what was supplied by you in your previous post (here), we didn’t make any changes to this other than replacing $order_id by $order->get_id()

Hello Ewout,

The author made a correction, and sent me new code as below (between the lines):
—————————————————————————————
global $wcst_order_model, $wcst_time_model;

$tracking_meta = $wcst_order_model->get_order_meta($order_id);
$shipping_traking_num = $tracking_meta[‘_wcst_order_trackno’][0];

$dispatch_date = isset($tracking_meta[‘_wcst_order_dispatch_date’][0]) ? $tracking_meta[‘_wcst_order_dispatch_date’][0] : __( ‘N/A’, ‘woocommerce’ ) ;
$dispatch_date = $wcst_time_model->format_data($dispatch_date);
—————————————————————————————

Please help and give me your code so I can put them on my child theme functions file. Thanks in advance!

Hey @cfm168,

The code updated with what you provided:

add_action( 'wpo_wcpdf_after_order_details', 'wpo_wcpdf_tracking_and_date', 10, 2 );
function wpo_wcpdf_tracking_and_date ($template_type, $order) {
	if ($template_type == 'invoice') {
		global $wcst_order_model, $wcst_time_model;

                $tracking_meta = $wcst_order_model->get_order_meta($order->get_id());
                $shipping_traking_num = $tracking_meta[‘_wcst_order_trackno’][0];

                $dispatch_date = isset($tracking_meta[‘_wcst_order_dispatch_date’][0]) ? $tracking_meta[‘_wcst_order_dispatch_date’][0] : __( ‘N/A’, ‘woocommerce’ ) ;
                $dispatch_date = $wcst_time_model->format_data($dispatch_date);
		?>
		<div class="shipping-tracking-date">
			<b>Tracking Number:</b>
			<div><?php echo $shipping_traking_num; ?></div>
			<b>Shipping Date:</b>
			<div><?php $dispatch_date; ?></div>
		</div>
		<?php
	}
}

Hi @dpeyou,

Thank you for your quick response. Now I can see the following printed on all previous Invoices.
Tracking Number:
Shipping Date:

But the value does not show up. Is it because of previous invoices? Will works for new invoice?

Please advise. Thanks!
