如何只对woocommerce产品进行星级评定，而不需要评论

我正在寻找代码，使我能够收集WooCommerce产品的明星评论，而无需用户提供任何评论。

下面的这段代码通过消除评论框让我走了那么远，但WordPress不允许保存提交内容。这段代码缺少什么吗？

function filter_woocommerce_product_review_comment_form_args( $comment_form ) {
    if ( function_exists( 'WC' ) && is_product() ) {
        $comment_form['comment_field'] = '<div class="comment-form-rating"><label for="rating">' . esc_html__( 'Your rating', 'your-theme-text-domain' ) . '</label><select name="rating" id="rating" required>
            <option value="">' . esc_html__( 'Rate&hellip;', 'your-theme-text-domain' ) . '</option>
            <option value="5">' . esc_html__( 'Perfect', 'your-theme-text-domain' ) . '</option>
            <option value="4">' . esc_html__( 'Good', 'your-theme-text-domain' ) . '</option>
            <option value="3">' . esc_html__( 'Average', 'your-theme-text-domain' ) . '</option>
            <option value="2">' . esc_html__( 'Not that bad', 'your-theme-text-domain' ) . '</option>
            <option value="1">' . esc_html__( 'Very poor', 'your-theme-text-domain' ) . '</option>
        </select></div>';

        $comment_form['fields']['author'] = '';
        $comment_form['fields']['email'] = '';
        $comment_form['fields']['url'] = '';
        $comment_form['comment_notes_before'] = '';
        $comment_form['label_submit'] = esc_html__( 'Submit Review', 'your-theme-text-domain' );
        $comment_form['title_reply'] = esc_html__( 'Leave a Review', 'your-theme-text-domain' );
    }
    return $comment_form;
}
add_filter( 'woocommerce_product_review_comment_form_args', 'filter_woocommerce_product_review_comment_form_args' );
