如何将变量传递给一个Woocomerce变量产品的变体属性？

Question

我有一个函数，它应该创建一个变体，并用值，变量产品的属性填充变体。为了变得更加灵活，我没有为产品属性创造价值，除了

我试了百种方法让价值坚持到变化，但他们没有。该变体是在后端创建的，但它没有任何值分配?????? PLEEEEASE帮助!!!!我在这里已经4天了。 ;（

归因于该产品属性的唯一值是“>> EMPTY < <”的值。/////////////变量$ DATA - >阵列（密钥 - >值），以使键==到产品atributes $产物 - > $ 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) {

Answer 1

我挣扎于同一个问题，关键在于属性的分类法。

如果标记为分类的属性，那么它需要slu instead，而不是字符串基于文本的attrs。所以首先检查

 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slug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()可能会有所帮助
