Display _global_unique_id meta on product page

Hello @Hangato,

You can add the following custom PHP snippet to your child theme’s functions.php file:

add_filter('etheme_product_meta_elements', function ($elements) {
    $elements['et_woo_gtin'] = esc_html__('Woo GTIN', 'xstore-child');
    return $elements;
});

add_action('etheme_product_meta_element_render', function($key, $local_product, $edit_mode, $_this) {
	switch ($key) {
		case 'et_woo_gtin':
			$gtin = $local_product->get_global_unique_id();
			$gtin_caption = esc_html__('GTIN', 'xstore-child');
			if ( $gtin ) { ?>
				<span class="et_woo_gtin_wrapper detail-container">
                    <span class="detail-label"><?php // PHPCS - the $sku_caption variable is safe. ?><?php echo $gtin_caption; // phpcs:ignore WordPress.Security.EscapeOutput.OutputNotEscaped ?>
                        </span>
                    <span class="et_woo_gtin"><?php // PHPCS - the $sku && $sku_missing variables are safe. ?><?php echo $gtin; // phpcs:ignore WordPress.Security.EscapeOutput.OutputNotEscaped ?>
                        </span>
                </span>
				<?php
			}
			break;
		
		default:
			// code...
			break;
	}
}, 10, 4);

Next, open your Single Product Builder (XStore Builders → Single Product Builder → Elementor Editor) and check the Product Meta widget. You will find a new option to display the Woo GTIN (you can modify the text in your code if needed as the WooCommerce provide one field for GTIN, UPC, EAN, or ISBN): https://gyazo.com/1606eb3947d2a7c2454338a458b64f77.

On the frontend (https://gyazo.com/732c5f36d4697edec8873e699da57849), you will see the correct GTIN value that you set in your product backend (https://gyazo.com/17e2bfbee0ddd1c51b68be9b889f5a93).

If you still require assistance, please provide us with temporary WP-Admin and FTP access to your website.
