根據Woocommerce中的產品標籤自動分配產品類別

Question

我目前使用wp_insert_post（）函數成功地將產品添加到Woocommerce中。

我現在試圖根據產品標籤將產品分配給相關類別。例如，如果產品添加了產品標籤「戒指」或「項鍊」，則會自動分配到「珠寶」類別。

使用以下函數，我可以在帖子上實現正確的功能，但在嘗試使用woocommerce中的產品帖子類型時沒有運氣。

工程職位：

function auto_add_category ($post_id = 0) { 
if (!$post_id) return; 
$tag_categories = array (
    'ring' => 'Jewellery', 
    'necklace' => 'Jewellery', 
    'dress' => 'Clothing', 
); 
$post_tags = get_the_tags($post_id); 
foreach ($post_tags as $tag) { 
    if ($tag_categories[$tag->name]) { 
    $cat_id = get_cat_ID($tag_categories[$tag->name]); 
    if ($cat_id) { 
     $result = wp_set_post_terms($post_id, $tags = $cat_id, $taxonomy = 'category', $append = true); 
    } 
    } 
    } 
} 
add_action('publish_post','auto_add_category'); 

我試圖重新利用的代碼對產品的工作方式如下：

function auto_add_category ($product_id = 0) { 
    if (!$product_id) return; 
$tag_categories = array (
    'ring' => 'Jewellery' 
    'necklace' => 'Jewellery', 
    'dress' => 'Clothing', 
); 
$product_tags = get_terms(array('taxonomy' => 'product_tag')); 
foreach ($product_tags as $tag) { 
    if ($tag_categories[$tag->name]) { 
     $cat = get_term_by('name', $tag_categories[$tag->name], 'product_cat'); 
     $cat_id = $cat->term_id; 
     if ($cat_id) { 
      $result = wp_set_post_terms($product_id, $tags = $cat_id, $taxonomy = 'product_cat', $append = true); 
     } 
    } 
} 
} 
add_action('publish_product','auto_add_category'); 

但是，它並沒有在分配相關的類別產品創造。任何協助將不勝感激這個新手編碼器混淆他的方式通過wordpress！

試試這個代碼：

function auto_add_category ($product_id = 0) { 

    if (!$product_id) return; 

    // because we use save_post action, let's check post type here 
    $post_type = get_post_type($post_id); 
    if ("product" != $post_type) return; 

    $tag_categories = array (
     'ring' => 'Jewellery' 
     'necklace' => 'Jewellery', 
     'dress' => 'Clothing', 
    ); 

    // get_terms returns ALL terms, so we have to add object_ids param to get terms to a specific product 
    $product_tags = get_terms(array('taxonomy' => 'product_tag', 'object_ids' => $product_id)); 
    foreach ($product_tags as $term) { 
     if ($tag_categories[$term->slug]) { 
      $cat = get_term_by('name', $tag_categories[$term->slug], 'product_cat'); 
      $cat_id = $cat->term_id; 
      if ($cat_id) { 
       $result = wp_set_post_terms($product_id, $cat_id, 'product_cat', true); 
      } 
     } 
    } 
} 
add_action('save_post','auto_add_category');
