如何将Woocomerce变量乘积的变量传递到变量的属性？

Question

我有一个函数，它应该创建一个变量，并用变量乘积的值，属性填充变量。为了变得更加灵活，我没有为产品属性创造值

我试过上百种方法，使值坚持变化，但他们没有。变体是在后端创建的，但它没有Atributed?？？？？？请帮忙！！我做这个已经4天了。（

归属于产品atributes的唯一值是“空转”(>&gtempty<<)价值。////////////变量数据-&>；数组（key->Value)，以便产品的Key==与产品相关的key->Value(key->Value)(key->Value)；PRODUCT_ID

function add_variable_product_to_cart($product_id, $data) {

$my_post = array(
    'post_title'=> 'Order_Printaway',
    'post_name' => 'product_' . $data["itemIdentifier"],
    'post_status' => 'publish',
    'post_parent' => $product_id ,//post is a child post of product post
    'post_type' => 'product_variation',//set post type to product_variation
    'guid'=>home_url() . '/?product_variation=product_' . $data["itemIdentifier"]
);

//Insert ea. post/variation into database:
$attID = wp_insert_post( $my_post );    

update_post_meta($attID, '_price', $data["final_price"]);
update_post_meta($attID, '_regular_price', $data["final_price"]);

foreach($data as $key => $value){

    $avail_attributes = array($value);
    wp_set_object_terms($product_id, $avail_attributes, $key);

    $thedata[$key]['name'] = $value;

}

update_post_meta( $attID,'_product_attributes',$thedata);

if ( ! is_admin() ) {
    $found = false;
    //check if product already in cart
    if ( sizeof( WC()->cart->get_cart() ) > 0 ) {
        // if product not found, add it
        if ( ! $found ){
           WC()->cart->add_to_cart( $product_id, 1, $attID);

        }
    }
    else{
        // if no products in cart, add it
       WC()->cart->add_to_cart( $product_id, 1, $attID);
    }
}
}

        if ( $attribute['is_taxonomy'] ) {
            $options = wc_get_product_terms( $post_id, $attribute['name'], array( 'fields' => 'slugs' ) );
        } else {
            $options = explode( WC_DELIMITER, $attribute['value'] );
        }

并用段块或字符串值填充attr_val。

 update_post_meta( $post_id, 'attribute_' . sanitize_title($attribute['name'] ), $attr_val);

wc_ajax::save_attributes()可能会有帮助
