这段代码对吗？ （使用catpcha的PHP POST方法）
我是一名非常菜鸟的 php 开发人员；我决定创建一个用户登录系统。 对于系统，我想使用验证码系统。我的问题是，当我单击“发送”按钮时，我无法发送表单的数据（两个文本框：用户名和邮件地址）。 为了让它发挥作用；我创建了一个接收表单数据的方法，该数据的发送方式如下： method_name($POST["username"],$POST["mail"]); 我想知道这是否正确，或者会存在一些安全问题或其他问题。
谢谢。
PD：抱歉我的英语……不太好。 这是索引页
<?php
require_once('recaptchalib.php');
require_once('home.php');

$privatekey = "bar";
$error = null;
if ($_POST['action'] == "register") {
$re_ip = $_SERVER["REMOTE_ADDR"];
$re_challenge = $_POST["recaptcha_challenge_field"];
$re_response = $_POST["recaptcha_response_field"];
$resp = recaptcha_check_answer($privatekey, $re_ip, $re_challenge, $re_response);
if ($resp->is_valid) {
// procesar registro
hello($_POST["username"],$_POST["usermail"]);
exit;
} else {
$error = $resp->error;

I am a very rookie php developer; and i decided create a user Login system.
For the system, i want use captcha system. My problem is that when i click the button "Send" i can't send the data of the form (two textbox: username and mail address).
For make it work; i created a method that recive the data of the form, this data is send like: method_name($POST["username"],$POST["mail"]);
i want to know if this is correct or it will have some security problem or maybe something else.
thanks.

如果无法发送表单，那么我会假设是因为表单声明缺少
action=URL。通常你会写：第二件事是电子邮件正则表达式。它错过了典型的有效字符，但也没有使用正确的 PCRE 分隔符。而是使用它而不是手动
preg_match $mailFilter：If the form cannot be sent, then I would assume because the form declaration lacks the
action=URL. Normally you would write:The second thing is the email regex. It misses the typical valid characters, but also doesn't use correct PCRE delimiters. Rather use this instead of a manual
preg_match $mailFilter:
