Hide empty custom field from Invoice

    I’m currently using this code to display a custom field (‘purchase_order’) on the invoice and packing slip. 

    add_action( 'wpo_wcpdf_after_order_data', 'wpo_wcpdf_purchase_order', 10, 2 );

function wpo_wcpdf_purchase_order ($document_type, $order) { 
$document = wcpdf_get_document( $document_type, $order ); ?>
        <tr class="purchase-order">
            <th>Purchase Order:</th>
            <td><?php $document->custom_field('purchase_order'); ?></td>
        </tr>
    <?php
}

    How can I ensure that the title ‘Purchase Order:’ does not display when the custom field is either non existent or empty?

    My attempts at wrapping the code in a conditional are not working.

    add_action( 'wpo_wcpdf_after_order_data', 'wpo_wcpdf_purchase_order', 10, 2 );

function wpo_wcpdf_purchase_order ($document_type, $order) {
$document = wcpdf_get_document( $document_type, $order );
$purchase_order = $document->custom_field('purchase_order');

if (!empty($purchase_order)) {
    ?>
    <tr class="purchase-order">
        <th>Purchase Order:</th>
        <td><?php echo $purchase_order; ?></td>
    </tr>
    <?php
}

    Check to see that your purchase_order meta key is actually empty in an order that isn’t a purchase order. It’s possible the meta key is there but has a value of ‘no’ or similar.

    Thanks for the prompt response.

    When I use the first example code, the invoice always displays the title ‘Purchase Order:’ and only displays the value of the purchase_order custom field when such a field exists and has a value.

    However, when I use the second example code, nothing is displayed, whether a purchase_order custom field is present and populated or not.

    Any idea what I’m doing wrong?

    Try this snippet

    add_action( 'wpo_wcpdf_after_order_data', 'wpo_wcpdf_purchase_order', 10, 2 );
function wpo_wcpdf_purchase_order ($document_type, $order) {
$document = wcpdf_get_document( $document_type, $order );
$purchase_order = $order->get_meta('purchase_order');

	if ( ! empty($purchase_order ) ) {
		?>
		<tr class="purchase-order">
			<th>Purchase Order:</th>
			<td><?php echo $purchase_order; ?></td>
		</tr>
		<?php
	}
}
