我有一个自定义的帖子类型“Product”，希望在创建新产品时自动创建一个帖子类别“Product Name”，这样帖子类别（非自定义帖子类别）将与新产品具有相同的名称，并且所有相关帖子都可以链接到自定义帖子类型。

我曾试图链接到wp\\u publish\\u帖子，但显然它已重命名为{$new_status}_{$post->post_type} 所以我想标签应该是publish\\u product？

    // adds category with name of product automatically
add_filter( \'publish_product\', \'my_publish_product\' );

function my_publish_product( $post ) {
    global $wpdb;
    $post_type = \'product\'; 

    if ( ! $post = get_post( $post ) )
        return;

    if ( \'publish\' == $post->post_status )
        return;

    $wpdb->update( $wpdb->posts, array( \'post_status\' => \'publish\' ), array( \'ID\' => $post->ID ) );

    clean_post_cache( $post->ID );

    $old_status = $post->post_status;
    $post->post_status = \'publish\';
    wp_transition_post_status( \'publish\', $old_status, $post );

    /** This action is documented in wp-includes/post.php */
    do_action( \'edit_post\', $post->ID, $post );
    /** This action is documented in wp-includes/post.php */
    do_action( "save_post_{$post->post_type}", $post->ID, $post, true );
    /** This action is documented in wp-includes/post.php */
    do_action( \'save_post\', $post->ID, $post, true );
    /** This action is documented in wp-includes/post.php */
    do_action( \'wp_insert_post\', $post->ID, $post, true );

    if ( \'post\' != $post_type ) {
        return;
    } else {
        add_action( \'wp_insert_post\', \'my_wp_insert_post($post->post_name)\' );
        return;
    }
}
function my_wp_insert_post( $post_name )
{
    $my_cat = array(
  \'cat_ID\' => 0,
  \'cat_name\' => $post_name, 
  \'category_parent\' => \'products\',
  \'taxonomy\' => \'category\' 
  );

    wp_insert_category($my_cat);
}
