Woocommerce产品变异分页问题(Woocommerce Product Variations

我做的单品变化的表，我试图做分页。我使用的是可变产品，一些自定义的属性。所以，问题是，分页不能正常工作，并显示页数太多。

例如，对于一个产品我有第一页和总上15层的变化，但示出了分页14总页面。此外，如果我例如2设置posts_per_page，那么所有的变化被乘以2（重复）等。

这是我的表

在functions.php文件的完整代码

function woocommerce_variable_add_to_cart(){
    global $product, $post, $woocommerce;

    $attributes = $product->get_attributes();

    $variations = find_valid_variations();

    if ( get_post_meta($post->ID, 'price_grid', true) ) {
        wp_enqueue_script( 'wc-add-to-cart-variation' );

        wc_get_template( 'single-product/add-to-cart/variable.php', array(
                'available_variations'  => $product->get_available_variations(),
                'attributes'            => $product->get_variation_attributes(),
                'selected_attributes'   => $product->get_variation_default_attributes()

我有我的一个项目类似的问题。我解决了它使用的jQuery数据表插件。试试，看看能否解决你的。
