我无法获取帖子数据以在不同页面上回显答案

【问题标题】：I cannet get post data to echo on a different page我无法获取帖子数据以在不同页面上回显

【问题描述】：

我已经创建了一个 register.php 页面，它具有用于用户输入的 html 表单，然后它会在 php 验证输入的地方发布到自身，这一切都按我的意愿工作。我可以在验证后回显数据而没有问题，但是当我使用标头重定向添加重定向到 register.inc.php 然后尝试从 register.inc.php 页面回显发布数据时，它不会这样做，几乎就像数据未发布到 register.inc.php 文件，但是，如果我在 register.php 页面中包含 register.inc.php，它将在 register.php 页面上回显数据，这肯定表明正在发送发布数据，最终我希望将此数据输入数据库，但显然如果没有看到帖子数据，我将无法看到，我尝试了一个无效的会话开始，我似乎无法通过任何研究解决这个问题已经完成了，我敢打赌这是我想念的非常简单的事情。下面是registration.php页面和register.inc.php页面，我没有足够的积分无法添加图片。

    <?php
//include_once 'includes/register.inc.php';
// define variables and set to empty values
$usernameErr = $emailErr = $passwordErr = $clubnameErr = "";
$username = $email = $password = $clubname = "";

if ($_SERVER["REQUEST_METHOD"] == "POST") {
  $username = test_input($_POST["name"]);
  $email = test_input($_POST["email"]);
  $password = test_input($_POST["password"]);
  $clubname = test_input($_POST["clubname"]);
}

function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}
if ($_SERVER["REQUEST_METHOD"] == "POST") {
  if (empty($_POST["username"])) {
    $usernameErr = "**Name is required**";
  } else {
    $username = test_input($_POST["username"]);
        if (!preg_match("/^[a-zA-Z ]*$/",$username)) {
      $usernameErr = "**Only letters and white space allowed**";
      exit();
    }
  }

  if (empty($_POST["email"])) {
    $emailErr = "**Email is required**";
  } else {
    $email = test_input($_POST["email"]);
    if (!preg_match("/([\w\-]+\@[\w\-]+\.[\w\-]+)/",$email)) {
      $emailErr = "**Invalid email format**";
    }
  }

  if (empty($_POST["password"])) {
    $passwordErr = "**Password is required**";
  } else {
    $password = test_input($_POST["password"]);
  }

    if (empty($_POST["confirmpassword"])) {
    $confirmpasswordErr = "**Please confirm password**";
  } else {
    $confirmpassword = test_input($_POST["confirmpassword"]);
  }

  if($_POST['password'] != $_POST['confirmpassword']){
   $confirmpasswordErr = "**Passwords did not match**";
   }

   if($_POST["password"] && strlen(trim($_POST["password"])) < 6)
    {
        $passwordErr = "**Password needs to be at least 6 characters**";
    } 

  if (empty($_POST["clubname"])) {
    $clubnameErr = "**Club Name is required**";
  } else {
    $clubname = test_input($_POST["clubname"]);
    if (!preg_match("/^[a-zA-Z ]*$/",$clubname)) {
      $clubnameErr = "**Only letters and white space allowed**";
    }

    if ($usernameErr == '' && $emailErr == '' && $passwordErr == '' && $confirmpasswordErr == '' && $clubnameErr == '') {
        $clubname;
    header("Location: includes/register.inc.php");
    }
  }
}


//echo $_POST['username'];

【问题讨论】：

重定向时不会保留发布数据 .... 不能那样工作。您可能应该包含 register.inc.php 文件，而不是重定向到它。
我已经这样做了，但它会直接回响到注册页面，无论如何我可以阻止它这样做吗？
我试过了，register.inc.php 仍然不会回显数据，除非返回到注册页面
我这样做的原因是为了避免发布未经哈希处理的密码，一旦我知道数据被发布到 register.inc.php 页面，我将在 register.php 页面上对密码进行哈希处理，除非我的想法是错误的

【解决方案1】：

如果要在页面之间传输数据，请在 register.inc.php 和 register.php 页面的开头使用session_start();。然后你可以在 register.inc.php 上调用它

此时你需要这样做：

if ($usernameErr == '' && $emailErr == '' && $passwordErr == '' && $confirmpasswordErr == '' && $clubnameErr == '') {

    $_SESSION['data'] = array($_POST['username'],$_POST['email'],$_POST['password'],$_POST['clubname']);
header("Location: includes/register.inc.php");
   //insert post data to session var.
}

然后在 register.inc.php

list($username,$email,$pass,$clubname) = $_SESSION['data'];
unset($_SESSION['data']);

//expand it on list then echo.

echo 'success'.'<br/><br/>';
echo $clubname.'<br/><br/>';
echo $username.'<br/><br/>';
echo $email.'<br/><br/>';
echo $password.'<br/><br/>';

【解决方案2】：

最好的办法是在 register.inc.php 中编写整个代码块，并将其包含在其中，并在其后加上 die() 语句。

【解决方案3】：

一种方法是通过url传递数据，就像

    register.inc.php?name=abcd&email=abcd@gmail.com

并使用register.inc.php中的$_GET['username'];和$_GET['email'];方法获取数据。

希望这会有所帮助。
