引导寄存器模式不能正常工作

我希望你们中的一些人能帮我解决这个问题。

我试图让我的引导模态工作，但似乎，它不会做我想要的东西。我像这样设置我的模态:

<div id="Sign-Up">
<div class="control-group">
<form name="myForm" role="form" action="register.php" method ="post" onsubmit="return validateForm()">
              <label class="control-label" for="Email">Email:</label>
              <div class="controls">
  <input id="Email" name="Email" class="form-control" type="text" placeholder="TestUser@testsite.com" class="input-large" required="">
              </div>
            </div>
            <!-- Text input-->
            <div class="control-group">
              <label class="control-label" for="userid">Alias:</label>
              <div class="controls">
               <input id="userid" name="userid" class="form-control" type="text" placeholder="TestUser" class="input-large" required=>
              </div>
            </div>
            <!-- Password input-->
            <div class="control-group">
              <label class="control-label" for="password1">Passwort:</label>
              <div class="controls">
                <input id="password1" name="password1" class="form-control" type="password" placeholder="********" class="input-large" required=>
                <em>1-8 Zeichen</em>
              </div>
            </div>
            <!-- Text input-->
            <div class="control-group">
              <label class="control-label" for="password2">Passwort wiederholen:</label>
              <div class="controls">
                <input id="password2" class="form-control" name="password2" type="password" placeholder="********" class="input-large" required>
              </form>
              </div>

我添加了一个"register.php"用于数据库插入:

<?php
    require('connection.php');
    // If the values are posted, insert them into the database.
    if (isset($_POST['userid']) && isset($_POST['password1'])){
        $username = $_POST['userid'];
        $email = $_POST['Email'];
        $password1 = $_POST['password1'];
        $password2 = $_POST ['password2'];
        if ($password1 == $password2) {
    echo "Password is OK";
} else  {
    echo "You entered two different passwords";
}
        $query = "INSERT INTO `users` (userid, password1, Email) VALUES ('$username', '$password1', '$email')";
        $result = mysql_query($query);
        if($result){
            $msg = "User Created Successfully.";
        }
    }
?>

最后是数据库连接connection.php:

<?php
define('DB_HOST','localhost');
define('DB_NAME','users');
define('DB_USER','****');
define('DB_PASSWORD','****');
$conn=mysql_connect(DB_HOST,DB_USER,DB_PASSWORD) or die("Failed to connect to MySQL: " . mysql_error());
$db=mysql_select_db(DB_NAME,$conn) or die("Failed to connect to MySQL: " . mysql_error());
if (mysqli_connect_errno($conn))
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }
else
{
echo "Successfully connected to your database…";
}
?>

如果我检查浏览器中的"register.php"，我可以看到我得到了一个有效的数据库连接。我现在的问题是，我不知道如何将数据提交到我的数据库中。如果我按下注册按钮，模态只是刷新到我的开始屏幕，没有任何数据插入。

如果有人能检查一下我的代码并知道那里有什么问题，那就太好了。

问候

PS:这是我编写的按钮:

    <div class="control-group">
      <label class="control-label" for="confirmsignup"></label>
      <div class="controls">
        <button id="confirmsignup" name="confirmsignup" type="submit" formmethod="post" class="btn btn-success" value="Anmelden">Anmelden</button>
      </div>
    </div>

这是我完全编码的模态现在，这似乎仍然不起作用:
