发布帖子时向作者发送电子邮件

Question

我想在文章发表后给作者发邮件。

我的代码

add_action( 'publish_post', 'send_notification' );
 function send_notification( $post_id ) {    
    $post     = get_post($post_id);
    $content = $post->post_content;
    $content = apply_filters('the_content', $content);
    $content = str_replace(']]>', ']]>', $content);
    $post_url = get_permalink( $post_id );
    $post_title = get_the_title( $post_id ); 
    $author   = get_userdata($post->post_author);
    $subject  = '$post_title';
    $message .= "<a href='". $post_url. "'>'".$post_title."'</a>\n\n";
    $message .= $content;
    wp_mail($author->user_email, $subject, $message ); 
}

邮件正常发送给作者，但他阅读了帖子内容的源代码。

我应该怎么做才能让作者正常通过电子邮件而不是帖子中的代码获取帖子

感谢您的帮助！

默认情况下，wp_mail 函数发送纯文本电子邮件，说明 post html 标签未转换。

要发送 html 电子邮件，您需要指定标题：

add_action( 'publish_post', 'send_notification' );
 function send_notification( $post_id ) {    
    $post     = get_post($post_id);
    $content = $post->post_content;
    $content = apply_filters('the_content', $content);
    $content = str_replace(']]>', ']]>', $content);
    $post_url = get_permalink( $post_id );
    $post_title = get_the_title( $post_id ); 
    $author   = get_userdata($post->post_author);
    $subject  = $post_title;
    $message .= "<a href='". $post_url. "'>'".$post_title."'</a>\n\n";
    $message .= $content;
   $headers = array('Content-Type: text/html; charset=UTF-8');
    wp_mail($author->user_email, $subject, $message, $headers ); 
}
