Question

我正在尝试将wordpress注册嵌入主页。我已经创建了一个自定义注册页面，问题是它调用了头信息，当我用php include包含它时，我得到了这个错误。

警告：无法修改标头信息 - 已发送的标头

有没有办法可以使用我的代码，但以某种方式改变它/以某种方式使用它，以便注册表单完全嵌入/使用ajax在页面中工作，但它的工作原理。我对Php并不陌生，所以请原谅这是一个愚蠢的问题：

当前注册码（在其自己的页面中工作，但不包括在主页模板中）

<?php
require_once(ABSPATH . WPINC . '/registration.php');
global $wpdb, $user_ID;
//Check whether the user is already logged in
if (!$user_ID) {

        if($_POST){
            //We shall SQL escape all inputs
            $username = $wpdb->escape($_POST['username']);
            if(empty($username)) { 
                echo "User name should not be empty.";
                exit();
            }
            $email = $wpdb->escape($_POST['email']);
            if(!preg_match("/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$/", $email)) { 
                echo "Please enter a valid email.";
                exit();
            }       

                $random_password = wp_generate_password( 12, false );
                $status = wp_create_user( $username, $random_password, $email );
                if ( is_wp_error($status) ) 
                    echo "Username already exists. Please try another one.";
                else {
                    $from = get_option('admin_email');
                    $headers = 'From: '.$from . "\r\n";
                    $subject = "Registration successful";
                    $msg = "Registration successful.\nYour login details\nUsername: $username\nPassword: $random_password";
                    wp_mail( $email, $subject, $msg, $headers );

                    echo "Please check your email for login details.";
                }

            exit();

        } else { 
            echo "";        
            ?>

Answer 1

使用自定义方法进行注册和邮寄是不安全的。

因此我建议您查看此http://digwp.com/2010/12/login-register-password-code/

我希望这就是你想要的。最好的。

正如webfan建议的那样，在主页上重现注册功能并不是一个好主意。更好的方法是从注册页面简单地剪切和粘贴登录表单，并保持表单action指向注册页面：

<form method="post" action="<?php echo site_url('wp-login.php?action=register', 'login_post') ?>">
  <!-- registration form HTML goes here -->
</form>
