Cannot Display Custom Meta Data on Items

    So I have a client who’s using woocommerce to send them orders for glasses prescriptions. There’s only 1 product but it has custom meta each time. I have it working on everything else on the site but not on the PDF. When I try to use any of the methods outlined in your documentation they either show up blank or throw an error. Here’s my custom function:

    
add_filter( 'wpo_wcpdf_before_item_meta', 'wpo_wcpdf_add_meta', 10, 3 );
function wpo_wcpdf_add_meta ($template_type, $item, $order) {
    // check if product exists first
    if (empty($item['product'])) return;
    
    $document = wcpdf_get_document( $template_type, $order, $item );
    if ($template_type == 'invoice') {
        
        
        
        ?>      

        <h3>Frame Info</h3>
        <table class="order-info" style="width:100%;">
        
            <?php
            if (!empty($item['product'])) {
                $field_name = '_frame_name';
                $frameName = method_exists($item['product'], 'get_meta') ? $item['product']->get_meta($field_name,true,'edit') : get_post_meta( $item['product']->id, $field_name, true );
                if ( !empty($frameName) ) {
                    echo '<div class="product-location">Frame Name: '.$frameName.'</div>';
                }
            }
            ?>
        
        </table>
            
        <?php

        }
    }

    The reason this throws an error is probably because your HTML formatting is off, you’re creating a table without cells but with a stray div in it:

    
<table class="order-info" style="width:100%;">
    <div class="product-location">Frame Name: xxxxxxxxx</div>
</table>

    This will probably work if you remove the table element from your code (or make it a div element, or put your .product-location in a <tr><td>...</td></tr>.

    My apoligies, I was more concerned about getting the data to work first and then make it look nice.

    I’ve cleaned up the code a bit. It doesn’t throw any errors but it does list Manufacturer as blank on the PDF:

    
add_action( 'wpo_wcpdf_before_item_meta', 'wpo_wcpdf_add_meta', 10, 3 );
function wpo_wcpdf_add_meta ($template_type, $item, $order) {
    // check if product exists first
    if (empty($item['product'])) return;
    
    $document = wcpdf_get_document( $template_type, $order, $item );
    //print_r($order);
    if ($template_type == 'invoice') {        
        $order_id = $order->get_meta('id');
        print_r($order_id);
        ?>      
        <h3>Frame Info</h3>
        <ul>
            <?php
                $frameManufacturer = $order->get_meta('_frame_manufacturer');
                ?>
                <li>Manufacturer: <?php echo($frameManufacturer)?></li>';
            ?>
        </ul>
        <?php
        }
    }

    I should also mention the data I’m trying to retrieve is in the item line’s meta data. When I printed the entire order array I did see my variables so there must be a way to display them.

    You have changed the function – the previous snippet pulled product meta:

    
$item['product']->get_meta($field_name);

    and the new one pulls order meta:

    
$order->get_meta('_frame_manufacturer');

    but you mention you need line item meta… that would be 

    
wc_get_order_item_meta( $item['item_id'], '_frame_manufacturer );
