Question

我创建了一个导入工具，用于从json文件导入数据，以便在我的自定义帖子类型中创建帖子。一切运作良好，我可以导入acf字段以及指定的术语。我的问题是，如何导入分配给该术语的子术语。

我现在有两个收集数据的变量。我希望有变量eventCategoryChildName将其vaule作为子项分配给eventCategoryID

  $eventCategoryChildName = $ev['OfficialCity'];
  $eventCategoryId = $ev['RegionID'];

以下是没有子条款的条款导入功能：

 // set category terms
 $cat_ids = $eventCategoryName;
 // Add these categories, note the last argument is true.
 wp_set_object_terms( $post_id, $cat_ids, 'lan', true );

所以我设法导入与正确父母相关联的孩子，但他们没有被检查到帖子

    // set category terms
    $cat_ids = $eventCategoryName;

    // Import category name
    $term_taxonomy_ids = wp_set_object_terms( $post_id, $cat_ids, 'lan', true );

    $parent_term = wp_set_object_terms( $post_id, $cat_ids, 'lan', true );

    // Check terms import for errors
    if ( is_wp_error( $term_taxonomy_ids ) ) {
        // There was an error somewhere and the terms couldn't be set.
        echo $return->get_error_message();
    } else {
        // Success! These categories were added to the post.
    }


    $parent_term = term_exists( $eventCategoryName, 'lan' ); 
    wp_insert_term(
      $eventCategoryChildName,                // Customize as you wish
      'lan',
      array(
          'parent'      => $parent_term['term_id'],
          'slug'        => $eventCategoryChildName  // Customize as you wish
      )
    );

    if ( !is_wp_error( $child_term_result ) ) {
      wp_set_object_terms( $post_id, $child_term_result['term_id'], 'lan', true );
  }

首先，您应该检查wp_set_object_terms的结果，看看是否返回了错误：

$term_taxonomy_ids = wp_set_object_terms( $post_id, $cat_ids, 'lan', true );
if ( is_wp_error( $term_taxonomy_ids ) ) {
    // There was an error somewhere and the terms couldn't be set.
    echo $return->get_error_message();
} else {
    // Success! These categories were added to the post.
}

然后，您要添加的术语可能不存在。在这种情况下，wp_set_object_terms将返回invalid_taxonomy错误。因此，您可能希望在分类中添加这样的缺失术语：

wp_insert_term(
    'Term Name',                      // Customize as you wish
    'lan',
    array(
        'description' => 'Term desc', // Customize as you wish
        'slug'        => 'lan-slug1'  // Customize as you wish
    )
);

// For child term:
$parent_term = term_exists( 'parent_term_id', 'lan' );
$child_term_result = wp_insert_term(
    'Child Term Name',                // Customize as you wish
    'lan',
    array(
        'parent'      => $parent_term['term_id']
        'description' => 'Term desc', // Customize as you wish
        'slug'        => 'lan-slug1'  // Customize as you wish
    )
);

// Add the child term to the post
if ( !is_wp_error( $child_term_result ) ) {
     wp_set_object_terms( $post_id, $child_term_result['term_id'], 'lan', true );
}

最后，请确保在-at至少 - Wordpress的init挂钩之后执行此代码。例如：

function parse_my_json() {
    // Your code here
}
add_action('init','parse_my_json');
