如何修复“此产品目前无货，无法使用。”更新版本后出现错误

Question

我有一个HP脚本来更新WooCommerce版本。运行代码后，我在后端有了新的变体，但它们不会在前端显示。相反，我收到一条错误消息“该产品目前无货，无法使用。”

function UpdateProduct() {

extract($_POST);

$BaseProdArray = array(

);

// Disable filtering
kses_remove_filters();
WriteLog('Filters removed.');

// Update the Base Product
wp_update_post( $BaseProdArray, $wp_error );

// Delete current Featured Image
// Check if post has featured image
  if (has_post_thumbnail($pid)) {
    // Get featured image id from this post
    $feat_img_id = get_post_thumbnail_id($pid);

我希望在产品首页上看到新的变化。相反，我收到错误消息“该产品当前无货且不可用。”
