对于激活电子邮件，您可以使用buddypress\\bp members\\bp members函数中的过滤器挂钩。php

$message = apply_filters( \'bp_core_signup_send_validation_email_message\', $message,    $user_id, $activate_url );

function gavin_welcome_message( $message, $user_id, $activate_url ) {
    $message = \'Gavin says something here... \' . $message;
    return $message; 
}
add_filter(\'bp_core_signup_send_validation_email_message\', \'gavin_welcome_message\', 15, 3);
