Question

我正在使用wp_mail()在发布新的自定义帖子类型sfwd-lessons时发送电子邮件。

我只想发送新帖子，而不是修改。

我认为这只会发送新帖子：

if ( !wp_is_post_revision( $post_id ) ) {

...但在现有帖子更新时，它仍在发送电子邮件。

完整代码：

// SEND EMAIL ONCE LESSON IS CREATED
function notify_subscriber_new_lesson($post_id) {

    //verify post is not a revision 
if ( !wp_is_post_revision( $post_id ) ) { 

        //gets subscribers to send email to
        // WP_User_Query arguments
        $args = array (
            'role'           => 'Subscriber',
        );


        // The User Query
        $user_query = new WP_User_Query( $args );

        // get email addresses from user objects
         $email_addresses = array();
        foreach ( $user_query->results as $user ) {
            $email_addresses[] = $user->user_email;
        }

        // build message
        $post_title = get_the_title( $post_id ); 
        $post_url = get_permalink( $post_id ); 
        $subject = 'Now available: ' . $post_title; 
        $url = "<a href='". $post_url. "'>" .$post_title. "</a>"; 

            ob_start(); ?>

    <?php

    ob_end_clean();

        //send email to all emails
        wp_mail($email_addresses, $subject, $message );
}
}
add_action( 'publish_sfwd-lessons', 'notify_subscriber_new_lesson' );

您应该使用函数 wp_get_post_revisions（），此时您正在检查父帖是否是修订版，这就是它始终返回false的原因。如果父项包含修订，此函数将返回子项目数组。

$revisions = wp_get_post_revisions( $post->ID );

if( count( $revisions ) === 0 ) {
    //Send an email
}

自定义帖子类型的wp_is_post_revision（）始终返回false
