Php WooCommerce 获取产品属性分类值

我能够成功地拉和更新后元预期使用以下.

function update_post_type_post_prodd(  $post_id ) {

$personalization = get_post_meta( $post_id, '_qty_discount_code', true );

if ($personalization === 'R'){

$gfdata ='a:28:{s:2:"id";}';
   
    $emptyRemoved = unserialize($gfdata);

    update_post_meta( $post_id,'_gravity_form_data', $emptyRemoved );
}
}
add_action( 'save_post_product', 'update_post_type_post_prodd' );

pull 元字段_qty_discount_code

如果它包含值R

保存后将元字段_gravity_form_data更新为$gfdata.

However，当我试图拉一个产品属性分类pa_personalization我得到蟋蟀.

我try 了多种方法，但都没有用.这看起来对吗？

function update_post_type_post_prodd(  $post_id ) {

//$personalization = get_post_meta( $post_id, 'pa_personalization', true );

$taxonomy = 'pa_personalization';
$meta = get_post_meta($post_id, 'attribute_'.$taxonomy, true);
$term = get_term_by('slug', $meta, $taxonomy);
$personalization = $term->name;

if ($personalization === 'yes'){

$emptyRemoved = unserialize($gfdata);

    update_post_meta( $post_id,'_gravity_form_data', $emptyRemoved );
}
}
//execute the function whenever post type is being updated
add_action( 'save_post_product', 'update_post_type_post_prodd' );
