Display in additional information tab, some product settings custom fields values

问题

I have added some custom fields to the WooCommerce product setting pages in the shipping tab.

I need to make it visible on Product page in Additional Information tab and also that it can be automatically used in compare plugins?

I need that it add the units also as in the existing weight and dimensions field.

Thanks.

Based on this answer made to one of your questions, here is the way to get this custom product fields data on front-end single product pages "Additional information" tab.

You will get that:

For this product settings custom fields:

As the custom fields are saved in the product meta data, we use Wordpress get_post_meta() function to get the values this way:

add_action( 'woocommerce_product_additional_information', 'custom_data_in_product_add_info_tab', 20, 1 );
function custom_data_in_product_add_info_tab( $product ) {

    //Product ID - WooCommerce compatibility
    $product_id = method_exists( $product, 'get_id' ) ? $product->get_id() : $product->id;

    // Get your custom fields data
    $custom_field1 = get_post_meta( $product_id, '_custom_meta_field1', true );
    $custom_field2 = get_post_meta( $product_id, '_custom_meta_field2', true );

    // Set your custom fields labels (or names)
    $label1 = __( 'Your label 1', 'woocommerce');
    $label2 = __( 'Your label 2', 'woocommerce');

    // The Output
    echo '<h3>'. __('Some title', 'woocommerce') .'</h3>
    <table class="custom-fields-data">
        <tbody>
            <tr class="custom-field1">
                <th>'. $label1 .'</th>
                <td>'. $custom_field1 .'</td>
            </tr>
            <tr class="custom-field2">
                <th>'. $label2 .'</th>
                <td>'. $custom_field2 .'</td>
            </tr>
        </tbody>
    </table>';
}

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.

This code is tested on WooCommerce 3+ and works

Now to use that data in your compare feature is an other question and you should provide, in a new question, the code involved in this compare feature…

I was trying to do the same thing, but I wanted to add the custom fields to the existing table, without creating a new one.

Sod if you want to add it into the additionnal information table you can use woocommerce_display_product_attributes filter

function yourprefix_woocommerce_display_product_attributes($product_attributes, $product){
    $product_attributes['customfield'] = [
        'label' => __('custom', 'text-domain'),
        'value' => get_post_meta($product->get_ID(), 'customfield', true),
    ];
    return $product_attributes;
}
add_filter('woocommerce_display_product_attributes', 'yourprefix_woocommerce_display_product_attributes', 10, 2);
