将频率添加到Woocommerce订阅

Question

我正在寻找开发人员来帮助我在Woocommerce订阅中添加选择频率订阅产品变化属性，请参阅链接-> https://staging-terravidaonline.kinsta.cloud/product/cbd-tattoo/

我开发了此代码，该代码允许在常规产品上显示订阅产品，并可以在两个产品之间以半径切换。我们本来想添加频率功能，但是由于某种原因，它没有将产品添加到购物车并显示错误消息。

由于某种原因，正确的产品未添加到购物车并显示错误消息：请选择产品选项… 为什么会发生？

如有任何疑问，请告诉我

感谢一百万

查看代码：

    $attribute_name = 'Frequency';
    $user_id        = get_current_user_id();  
    /*$product_attribute = wc_display_product_attributes($product); */

if ( isset( $linked_id ) &&  $linked_id ) {
    $linked_product = wc_get_product( $linked_id[0] );
    // If linked object is an actual product, set $display to true
    $attributes = $linked_product->get_attribute( 'pa_frequency' );

    if ( is_object( $linked_product ) ) {
        $display = true;
    }
