自定义WordPress模板中的新用户电子邮件

Question

从一个注册用户的自定义函数中，我插入了这个函数来生成和覆盖WordPress系统的电子邮件以获得新用户通知。

function custom_wp_new_user_notification_email( $wp_new_user_notification_email, $user, $blogname ) {
global $wpcargo;
$user_url = stripslashes( $user->user_url );
$user_login = stripslashes( $user->user_login );
$user_email = stripslashes( $user->user_email );
$user_firstname = stripslashes( $user->user_firstname );
$user_last_name = stripslashes( $user->user_last_name );
$user_pass = stripslashes( $user->user_pass );
$message = file_get_contents('../email/mail-template.php');
$wp_new_user_notification_email['subject'] = sprintf( '[%s] Welcome.', $blogname );
$wp_new_user_notification_email['headers'] = array('Content-Type: text/html; charset=UTF-8');
$wp_new_user_notification_email['message'] = $message; 
return $wp_new_user_notification_email;
}
add_filter( 'wp_new_user_notification_email', 'custom_wp_new_user_notification_email', 10, 3 );

正在发送电子邮件，但我无法将用户数据打印在PHP/HTML文件中。

<p style="margin-top:0;margin-bottom:12px;"><b>Name</b>: <?php $user_firstname; ?></p>

我的代码错了，有什么建议吗？

我会使用locate_template作为电子邮件内容，使用output buffering而不是file_get_contents——正如@Zak所指出的，你必须使用echo作为输出，否则它不会显示。

function custom_wp_new_user_notification_email( $wp_new_user_notification_email, $user, $blogname ) {
global $wpcargo;
$user_url = stripslashes( $user->user_url );
$user_login = stripslashes( $user->user_login );
$user_email = stripslashes( $user->user_email );
$user_firstname = stripslashes( $user->user_firstname );
$user_last_name = stripslashes( $user->user_last_name );
$user_pass = stripslashes( $user->user_pass );
ob_start();
include( locate_template( '/email/mail-template.php' ); // This path may vary depending on your setup.
$wp_new_user_notification_email['message'] = ob_get_clean();
$wp_new_user_notification_email['subject'] = sprintf( '[%s] Welcome.', $blogname );
$wp_new_user_notification_email['headers'] = array('Content-Type: text/html; charset=UTF-8');
return $wp_new_user_notification_email;
}
add_filter( 'wp_new_user_notification_email', 'custom_wp_new_user_notification_email', 10, 3 );

在您的模板中，您需要确保对正在输出的任何内容进行回显和esc_html()。

<?php echo esc_html( $user_firstname ); ?>
