更新：

代码按原样编写，并将保持这种状态。但是，现在它不会将用户在表单中写入的数据提交到数据库。怎么了。

这是第一个文件。它包含 XML HTTP REQUEST 和 html 表单。该文件还包含野生 .

表单上的按钮是type="submit"; 这将提交表单并重定向页面，除非您return false;在onclick属性中有它。相反，我建议将按钮更改为常规按钮而不是提交按钮：

<input type="button" name="submit" value="Register" onclick="load('register.php', 'result');" />

此更改将阻止您的页面在提交表单后重定向。

编辑：查看完整代码后，POST 页面看起来在处理中存在逻辑错误（以及一些语法错误；请参阅我对关闭花括号问题的评论）。

该if (empty($errors) === true) {块以} else {您输出的用户已成功注册的 else 块内的 and 结尾。翻译过来，这意味着“如果有初始错误，告诉用户他们注册成功”。相反，将之后（包括）的所有内容更改} else {为：

if (!empty($_POST) && empty($errors)) {
    // the form has been submitted and there are no errors
    echo 'You have successfully registered. Please check your email to activate your account.';
    $register_data = array(
    'username'              => $_POST['username'],      
    'password'              => $_POST['password'],
    'first_name'            => $_POST['first_name'],
    'last_name'             => $_POST['last_name'],
    'email'                     => $_POST['email'],
    'email_code'            => md5($_POST['username'] + microtime())
                                 );
    register_user($register_data);
} else if (!empty($errors)) {
    // there are errors =[
    echo output_errors($errors);
}
