How to add label for custom fields in woocommerce?

To add labels for custom fields in WooCommerce, you can use the following steps:

1. Open your functions.php file in your theme folder (or child theme folder) using an FTP client or file manager.
2. Add the following code snippet to your functions.php file:

add_filter('woocommerce_get_custom_product_tabs', 'add_custom_tab_fields');
function add_custom_tab_fields($fields){
    // Add label for custom field
    $fields['custom_tab'] = array(
        'label'  => __('Custom Field Label', 'woocommerce'),
        'target' => 'your_custom_field_name',
    );
    return $fields;
}

1. Replace 'Custom Field Label' with the desired label for your custom field.
2. Replace 'your_custom_field_name' with the actual name of your custom field.
3. Save the functions.php file and refresh your website to see the changes. Your custom field should now have a label displayed next to it in the WooCommerce product page.

Note: Make sure to backup your functions.php file before making any changes, in case you need to revert to the original code.
