将姓氏和名字添加到Wordpress注册表

Question

我在WP的注册表中只有选项的用户名，电子邮件和密码。

//1. firstname 

add_action（'register_form'，'myplugin_register_form'）; 功能myplugin_register_form（）{

$first_name = (! empty($_POST['first_name'])) ? trim($_POST['first_name']) : ''; 

    ?> 

    <?php 
} 

//2. Add validation. In this case, we make sure first_name is required. 
add_filter('registration_errors', 'myplugin_registration_errors', 10, 3); 
function myplugin_registration_errors($errors, $sanitized_user_login, $user_email) { 

    if (empty($_POST['first_name']) || ! empty($_POST['first_name']) && trim($_POST['first_name']) == '') { 
     $errors->add('first_name_error', __('<strong>ERROR</strong>: You must include a first name.', 'mydomain')); 
    } 

    return $errors; 
} 

//3. Finally, save our extra registration user meta. 
add_action('user_register', 'myplugin_user_register'); 
function myplugin_user_register($user_id) { 
    if (! empty($_POST['first_name'])) { 
     update_user_meta($user_id, 'first_name', trim($_POST['first_name'])); 
    } 
} 

在我的报名表（模板）我已经放在以下几点：

   <label><?php _e('First Name', APP_TD) ?></label> 
       <input tabindex="3" type="text" name="first_name" class="text regular-text" id="display_name" value="<?php echo esc_attr(wp_unslash($first_name)); ?>" maxlength="100" /> 

和它的作品，因为它应该。它抓住名字并将其放入用户配置文件中。不过，我不知道如何添加姓以及我是一个初学者，出于某种原因，我不能得到姓氏的工作。帮助将不胜感激。

我从未在WP上使用过类似的东西。你把这个代码放在哪里？

不过我会尝试这样的东西执行：

//1. Fistname 

add_action('register_form', 'myplugin_register_form'); function myplugin_register_form() { 

$first_name = (! empty($_POST['first_name'])) ? trim($_POST['first_name']) : ''; 
$last_name = (! empty($_POST['last_name'])) ? trim($_POST['last_name']) : ''; 

?> 

<?php 
} 

//2. Add validation. In this case, we make sure first_name is required. 
add_filter('registration_errors', 'myplugin_registration_errors', 10, 3); 
function myplugin_registration_errors($errors, $sanitized_user_login, $user_email) { 

    if (empty($_POST['first_name']) || ! empty($_POST['first_name']) && trim($_POST['first_name']) == '') { 
    $errors->add('first_name_error', __('<strong>ERROR</strong>: You must include a first name.', 'mydomain')); 
    } 

    if (empty($_POST['last_name']) || ! empty($_POST['last_name']) && trim($_POST['last_name']) == '') { 
    $errors->add('last_name_error', __('<strong>ERROR</strong>: You must include a last name.', 'mydomain')); 
    } 

    return $errors; 
} 

//3. Finally, save our extra registration user meta. 
add_action('user_register', 'myplugin_user_register'); 
function myplugin_user_register($user_id) { 
    if (! empty($_POST['first_name'])) { 
     update_user_meta($user_id, 'first_name', trim($_POST['first_name'] )); 
    } 

    if (! empty($_POST['last_name'])) { 
     update_user_meta($user_id, 'last_name', trim($_POST['last_name'])); 
    } 
}
