HTML – WordPress自定义注册表

> A custom WordPress theme
> A Page Template
>使用页面模板的WordPress Page

如果有这三个部分,可以在页面模板中执行以下操作：

<?php
/*
Template Name: Registration
*/

global $current_user;
get_currentuserinfo();

$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$company = $_POST['company'];

if (($firstname != '') && ($lastname != '') && ($company != '')) {
    // TODO: Do more rigorous validation on the submitted data

    // TODO: Generate a better login (or ask the user for it)
    $login = $firstname . $lastname;

    // TODO: Generate a better password (or ask the user for it)
    $password = '123';

    // TODO: Ask the user for an e-mail address
    $email = 'test@example.com';

    // Create the WordPress User object with the basic required information
    $user_id = wp_create_user($login,$password,$email);

    if (!$user_id || is_wp_error($user_id)) {
       // TODO: Display an error message and don't proceed.
    }

    $userinfo = array(
       'ID' => $user_id,'first_name' => $firstname,'last_name' => $lastname,);

    // Update the WordPress User object with first and last name.
    wp_update_user($userinfo);

    // Add the company as user metadata
    update_usermeta($user_id,'company',$company);
}

if (is_user_logged_in()) : ?>

  <p>You're already logged in and have no need to create a user profile.</p>

<?php else : while (have_posts()) : the_post(); ?>

<div id="page-<?php the_ID(); ?>">
    <h2><?php the_title(); ?></h2>

    <div class="content">
        <?php the_content() ?>
    </div>

    <form action="<?php echo $_SERVER['REQUEST_URI'] ?>" method="post">
        <div class="firstname">
            <label for="firstname">First name:</label>
            <input name="firstname"
                   id="firstname"
                   value="<?php echo esc_attr($firstname) ?>">
        </div>
        <div class="lastname">
            <label for="lastname">Last name:</label>
            <input name="lastname"
                   id="lastname"
                   value="<?php echo esc_attr($lastname) ?>">
         </div>
         <div class="company">
            <label for="company">Company:</label>
            <input name="company"
                   id="company"
                   value="<?php echo esc_attr($company) ?>">
         </div>
    </form>
</div>

<?php endwhile; endif; ?>

现在,当您想要检索已存储的内容时,您需要知道信息是在User对象本身内还是在元数据中.要检索(登录用户的)姓名和姓氏,请执行以下操作：

global $current_user;
$firstname = $current_user->first_name;
$lastname = $current_user->last_name;

要检索公司名称(已登录用户)：

global $current_user;
$company = get_usermeta($current_user->id,'company');

这是它的基本要点.这里仍然缺少很多东西,例如验证,错误消息输出,WordPress API中发生的错误处理等等.还有一些重要的TODO,你必须在代码甚至可以工作之前处理.代码应该也可以分成几个文件,但我希望这足以让你入门.
