Get WooCommerce product variation attribute terms in admin products general box

Question

I display the id and sku of each variable product in the general tab - of the wp admin product data box with the following code. Any idea how to get the the variable product attribute name too - in this case "test 1" and "test 2"?

The variations

The general tab

The code

<?php   
    add_action( 'woocommerce_product_options_general_product_data', 'echo_product_id_sku_general_tab' );
    function echo_product_id_sku_general_tab() {
        
        $children_ids = wc_get_product()->get_children();
        $count        = 0;
        
        // Loop through the variations Ids
        foreach( $children_ids as $child_id ) {

            $count++;
            $pr_id_variable = wc_get_product($child_id)->get_id();
            $pr_sku_variable = wc_get_product($child_id)->get_sku();
            
        ?>

        <p class="form-field">
            <label><?php _e( 'Variation', 'woocommerce' ); ?> <?php echo $count; ?> ID</label>
            <input type="text" value="ID<?php echo $pr_id_variable; ?>"></input>
        </p>            
        
        <p class="form-field">
            <label><?php _e( 'Variation', 'woocommerce' ); ?> <?php echo $count; ?> SKU</label>
            <textarea><?php echo $pr_sku_variable; ?></textarea>
        </p>    
        
        <?php } ?>
<?php } ?>

For variation attribute names (variation Id and sku), you can use the following:

add_action( 'woocommerce_product_options_general_product_data', 'echo_product_id_sku_general_tab' );
function echo_product_id_sku_general_tab() {
    global $product_object;

    if( $product_object->is_type('variable') ) {
        $count = 1;

        foreach( $product_object->get_children() as $variation_id ) {
            $variation = wc_get_product($variation_id);
            $name      = array();

            foreach( $variation->get_attributes() as $taxonomy => $term_slug ) {
                $name[] = get_term_by( 'slug', $term_slug, $taxonomy )->name;
            }

            echo '<p><strong>'. sprintf( __("Variation %s Name: %s", "woocommerce"), $count, '</strong>' . implode(' - ', $name) ) .'</p>

            <p class="form-field">
            <label>' . sprintf( __("Variation %s ID", "woocommerce"), $count) . '</label>
                <input type="text" value="ID' . $variation_id . '"></input>
            </p>

            <p class="form-field">
                <label>' . sprintf( __("Variation %s SKU", "woocommerce"), $count) . '</label>
                <textarea>' . $variation->get_sku() . '</textarea>
            </p>';
            $count++;
        }
    }
}

Code goes in functions.php file of the active child theme (or active theme). Tested and works.

Note: this works for product attribute taxonomies only (starting with "pa_"), but not with custom attributes.
