wordpress - 如何在wp_mail 函数中的消息部分显示图像？

Question

我正在尝试在帖子发布时发送邮件。为此，我在我的 function.php 文件中编写了代码，邮件正确发送，但特色图片未发送。我想显示贴在帖子上的特色图片。现在在邮件中不显示特色图片，但显示特色图片的链接。

我该怎么做才能完成在邮件中显示特色图片的任务？我附上我在 function.php 文件中编写的代码:

function mysendmail($post_id) {

$post = get_post($post_id);
$author = get_userdata($post->post_author);
$subject = "Post Published: ".$post->post_title."";

$message = "
      Hi ".$author->display_name.",

      Your post, \"".$post->post_title."\" has just been published.

      View post: ".get_permalink( $post_id )."

      Your Image: ".get_the_post_thumbnail( $post->ID )."

      Thanks"
      ;

   wp_mail($author->user_email, $subject, $message);
}
add_action('publish_post', 'mysendmail');

要通过wp_mail 函数附加文件，您需要在其中使用$attachments 参数。其中你需要给出附件的绝对文件路径。

function mysendmail($post_id) {

$post = get_post($post_id);
$author = get_userdata($post->post_author);
$subject = "Post Published: ".$post->post_title."";


$attachments = get_attached_file( get_post_thumbnail_id( $post_id ));
$headers[] = '';


$message = "
      Hi ".$author->display_name.",

      Your post, \"".$post->post_title."\" has just been published.

      View post: ".get_permalink( $post_id )."

      Thanks"
      ;

   wp_mail($author->user_email, $subject, $message, $headers, $attachments);
}
add_action('publish_post', 'mysendmail');
