我的WP functions.php文件上有一个非常简单的PHP代码，它创建了一个新注释：
$time = current_time('mysql');
$com_meta = array(
"img_id" => $attach_id,
);
// $attach_id holds the ID of an image I want to attach to the comment in comment_meta
$data = array(
'comment_post_ID' => 2819,
'comment_author' => 'My test title',
'comment_author_email' => '[email protected]',
'comment_content' => 'Test comment message.',
'comment_type' => '',
'comment_date' => $time,
'comment_approved' => 0,
'comment_meta' => $com_meta,
);
$comm_id = wp_insert_comment( $data );
die( 'comment created, comment id: ' . $comm_id );
没有PHP错误，并且注释创建就很好。像“我的测试标题”这样的所有其他数据都按预期存在。只有comment_meta字段完全丢失。在$ comment对象中，甚至没有空的comment_meta。
我可能会缺少什么？
这是$ comment对象的外观：
WP_Comment对象（[comment_ID] => 9 [comment_post_ID] => 2819 [comment_author] =>我的测试标题[comment_author_email] => [email protected] [comment_author_url] => [comment_author_IP] => [comment_date] => 2019-10-18 13:33:03 [comment_date_gmt] => 2019-10-18 10:33:03 [comment_content] =>测试评论消息[comment_karma] => 0 [comment_approved] => 0 [comment_agent] = > [comment_type] => [comment_parent] => 0 [user_id] => 0 [children：protected] => [populated_children：protected] => [post_fields：protected] => Array（[0] => post_author [1] => post_date [2] => post_date_gmt [3] => post_content [4] => post_title [5] => post_excerpt [6] => post_status [7] => comment_status [8] => ping_status [9] => post_name [10] => to_ping [11] => ping [12] => post_modified [13] => post_modified_gmt [14] => post_content_filtered [15] => post_parent [16] => guid [17] => menu_order [ 18] => post_type [19] => post_mime_type [20] => comment_count）））>
我在WP functions.php文件中有一个非常简单的PHP代码，它创建了一个新注释：$ time = current_time（'mysql'）; $ com_meta = array（“ img_id” => $ attach_id，）; ...
我找到了答案。
