我已经提取了回复电子邮件。原始电子邮件保存为CPT，并在我的插件中作为票据使用。我希望回复邮件作为对原始邮件的评论。

 for($j = 1; $j <= $total; $j++){
            $mail = $emails->get($j);
//This checks if the email is reply or not and if the email is reply make it comment to its original post. 
    if ((!empty($mail[\'header\']->references )) && ($mail[\'header\']->references ) == ($mail[\'header\']->message_id )
                {
                    $comment_array = array(
                        \'comment_content\' => $mail[\'body\'],
                        \'comment_post_ID\' => ,

                    )
                    wp_insert_comment($comment_array);
                }
           }

我区分了回复电子邮件和原始电子邮件，但我不知道如何将这些电子邮件保留为原始电子邮件的评论。这就是我wp_insert_post 看起来像：

$post_array = array( 
            \'post_content\'  => $mail[\'body\'],
            \'post_title\'    => $mail[\'header\']->subject,
            \'post_type\'     => \'faqpress-tickets\',
            \'post_author\'   =>  ucwords(strstr($mail[\'header\']->fromaddress, \'<\',true)),
            \'post_status\'   => \'publish\',
            \'meta_input\'    => array(   
                \'User\'      => ucwords(strstr($mail[\'header\']->fromaddress, \'<\',true)),
                \'From\'      => preg_replace(\'~[<>]~\', \'\', strstr($mail[\'header\']->fromaddress, \'<\')),
                \'Email\'     => $mail[\'header\']->Date,
                \'ticket_id\' => $mail[\'header\']->message_id,   
            ),
        );
      //wp_insert_post( $post_array );

如果有人知道怎么做。这将是一个很大的帮助。

$post_id = wp_insert_post( $post_array );

$posts = get_posts( array(
    \'post_type\'  => \'faqpress-tickets\',
    \'meta_key\'   => \'ticket_id\',
    \'meta_value\' => $mail[\'header\']->message_id,
) );

if ( ! empty( $posts ) ) {
    $comment_array = array(
        \'comment_content\' => $mail[\'body\'],
        \'comment_post_ID\' => $posts[0]->ID,
    );

    wp_insert_comment( $comment_array );
}
