EAN code in pdf invoice

Hi @krysteo,

Try this code snippet to display the EAN code after the item meta:

/**
 * PDF Invoices & Packing Slips for WooCommerce:
 * Displays the EAN code after the item meta
 */
add_action( 'wpo_wcpdf_after_item_meta', function( $document_type, $item, $order ) {
	if ( ! empty( $item ) && ( $product = $item['product'] ) ) {
		if ( ! empty( $ean_code = $product->get_global_unique_id() ) ) {
			echo '<div class="product-ean" style="font-size:7pt">EAN: ' . $ean_code . '</div>';
		}
	}
}, 10, 3 );

If you haven’t worked with code snippets (actions/filters) or functions.php before, read this guide: How to use code snippets.

We also have a blog post here that you may find helpful about adding custom code to your site.

Let me know whether it worked or you need more help!
