Custom Fields Not Appearing in Email Attachments

Hello @minamt,

> when viewed through the document
What do you mean? The PDF Preview?

Do they only appear in the PDF Preview or do they also appear when generated manually?

(Disregard the arrow)

(WooCommerce Bulk actions at WooCommerce > Orders)

(Manual PDF Creation: Action Buttons for PDF Creation)


Do you have any relevant errors?

Hi Darren,
The value of the custom fields appear blank only when sent as an attachment in email, otherwise in preview, generated manually or using the download or link shortcode it’s appearing fine

@minamt could you share the code snippet that you’re using to add these fields, please?

@dwpriv,
Sure here’s the code I added to the custom invoice template

<?php 
$approval_code = $order_key->get_meta('approval_code');
$transaction_id = $order_key->get_meta('transaction_id');
$transaction_time = $order_key->get_meta('transaction_time');
$orderNumber = $order_key->get_meta('orderNumber');
?>

<table class="cib-data">
	<tr>
		<td class = "order-data">
            Transaction ID: <?php echo $transaction_id; ?>
		</td>
	</tr>
    <tr>
		<td class = "order-data">
            Order number: <?php echo $orderNumber; ?>
		</td>
	</tr>
    <tr>
		<td class = "order-data">
            Approval code: <?php echo $approval_code; ?>
		</td>
	</tr>
    <tr>
		<td class = "order-data">
            Transaction time: <?php echo $transaction_time; ?>
		</td>
	</tr>
</table>
<?php do_action( 'wpo_wcpdf_before_order_details', $this->get_type(), $this->order ); ?>

Is it the way the action is added?

The issue may be with your custom template. You can try the below edit to your snippet that you can add to the template-functions.php file in your custom template folder. You can then remove the prior code above. You can alternative paste it in a plugin like Code Snippets

add_action( 'wpo_wcpdf_before_order_details', function( $document_type, $order ) {
	if ( !empty ( $order ) ) {
		$approval_code = $order->get_meta('approval_code');
		$transaction_id = $order->get_meta('transaction_id');
		$transaction_time = $order->get_meta('transaction_time');
		$orderNumber = $order->get_meta('orderNumber');
		?>
			<table class="cib-data">
				<tr>
					<td class = "order-data">
						Transaction ID: <?php echo $transaction_id; ?>
					</td>
				</tr>
				<tr>
					<td class = "order-data">
						Order number: <?php echo $orderNumber; ?>
					</td>
				</tr>
				<tr>
					<td class = "order-data">
						Approval code: <?php echo $approval_code; ?>
					</td>
				</tr>
				<tr>
					<td class = "order-data">
						Transaction time: <?php echo $transaction_time; ?>
					</td>
				</tr>
			</table>
		<?php
	}
}, 10, 2 );
