好的，真的很奇怪...我正在研究一个非常基本的注册脚本，但它会返回：

  

注意：未定义的索引：用户名   第42行的C：\ xampp \ htdocs \ Zephryte \ app \ classes \ users.class.php

     

注意：未定义的索引：电子邮件   第46行的C：\ xampp \ htdocs \ Zephryte \ app \ classes \ users.class.php

     

注意：未定义的索引：电子邮件   第50行的C：\ xampp \ htdocs \ Zephryte \ app \ classes \ users.class.php

     

注意：未定义的索引：电子邮件确认   第50行的C：\ xampp \ htdocs \ Zephryte \ app \ classes \ users.class.php

     

注意：未定义索引：passwordp in   第54行的C：\ xampp \ htdocs \ Zephryte \ app \ classes \ users.class.php

注意：未定义索引：passwordp in   第66行的C：\ xampp \ htdocs \ Zephryte \ app \ classes \ users.class.php

     

注意：未定义的索引：用户名   第70行的C：\ xampp \ htdocs \ Zephryte \ app \ classes \ users.class.php

这非常奇怪，因为我将所有输入字段命名为相应的变量：

<input type="text" name="username" size="45" placeholder="Username..." class="input" style="width: 98%;"  />
<input type="text" name="email" size="45" placeholder="E-Mailadres..." class="input" style="width: 98%;" />

等等......我在这里错过了什么吗？

编辑：

因为要求所有相关的PHP＆amp; HTML代码：

HTML：

    <form action="index.php?p=register" method="post" autocomplete="off">
      <table align="center" cellpadding="8" style="width: 100%;">
  <tr>
  <td style="width: 100%;">
  <input type="text" name="username" size="45" placeholder="Username..." class="input" style="width: 98%;"  />
  </td>
  </tr>
  <tr>
  <td style="width: 100%;">
  <input type="text" name="email" size="45" placeholder="E-Mailadres..." class="input" style="width: 98%;" />
  </td>
  </tr>
  <tr>
  <td style="width: 100%;">
  <input type="text" name="emailconfirm" size="45" placeholder="E-Mailadres bevestigen..." class="input" style="width: 98%;" />
  </td>
  </tr>
  <tr>
  </tr>
  <tr>
  <td style="width: 100%;">
  <input type="password" name="passwordp" size="45" placeholder="Wachtwoord..." class="input" style="width: 98%;"  />
  </td>
  </tr>
  <tr>
  </tr>
  <tr>
  <td width="100%">
  <input type="password" name="passwordconfirm" size="45" placeholder="Wachtwoord bevestigen..." class="input" style="width: 98%;" />
  </td>
  </tr>  
  <tr>
  <td style="width: 100%;">
  <input type="text" name="skype" size="45" placeholder="Skype..." class="input" style="width: 98%;" />
  </td>
  </tr>
  <tr>
  </tr>
  <td width="30%">
  <input type="submit" name="register" value="Registreren" class="button small orange" style="width: 100%;">
  </td>
  </table>
  </form>

PHP：

将isset添加到您的PHP：

public function register()
{
    $query = $this->db->conn->prepare('INSERT INTO ht_users VALUES "", ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?'); //22
    $errors = array();
    if (!isset($_POST['username']) || strlen($_POST['username']) < 3)
    {
        $errors[] = "Je gebruikersnaam is niet geldig";
    }
    if (!isset($_POST['email']) || !filter_var($_POST['email'], FILTER_VALIDATE_EMAIL))
    {
        $errors[] = "Je emailadres is niet geldig";
    }
    if (!isset($_POST['email']) || !isset($_POST['emailconfirm']) || $_POST['email'] !== $_POST['emailconfirm'])
    {
        $errors[] = 'Je emailadressen zijn niet \'t zelfde!';
    }
    if (!isset($_POST['passwordp']) || !isset($_POST['passwordcomfirm']) || $_POST['passwordp'] !== $_POST['passwordcomfirm'])
    {
        $errors[] = 'Je wachtwoorden zijn niet \'t zelfde';
    }
    if (!isset($_POST['username']) || !ctype_graph($_POST['username']))
    {
        $errors[] = 'Je gebruikersnaam bezit ongeldige tekens!';
    }
    if (!isset($_POST['passwordp']) || strlen($_POST['passwordp']) < 6)
    {
        $errors[] = 'Je wachtwoord moet op z\'n minst 6 tekens lang zijn';
    }
    if (!isset($_POST['passwordp']) || strlen($_POST['passwordp']) > 20)
    {
        $errors[] = 'Je wachtwoord mag maximaal 20 tekens bevatten!';
    }
    if (!isset($_POST['username']) || $this->checkUsername($_POST['username']))
    {
        $errors[] = 'Oeps! Er bestaat al een account op deze Habbonaam!<br>Ben je misschien je <a href="?p=lostpass">wachtwoord vergeten</a>?';
    }
    if (!isset($_POST['email']) || $this->checkEmail($_POST['email']))
    {
        $errors[] = 'Oeps! Er bestaat al een account op dit emailadres!<br>Ben je misschien je <a href="?p=lostpass">wachtwoord vergeten</a>?';
    }
    if (count($errors) > 0)
    {
        echo 'NEUKEN';
        //return $errors;
        exit();
    }
    $password = md5($_POST['passwordp']);
    $data = date('d-M-Y');
    $ipAddress = $_SERVER['REMOTE_ADDR'];
    if (array_key_exists('HTTP_X_FORWARDED_FOR', $_SERVER)) {
        $ipAddress = array_pop(explode(',', $_SERVER['HTTP_X_FORWARDED_FOR']));
    }

    $query->bind_param('ssssssssssssssssssssss', $data, $username, $password, NULL, $email, $this->generateCode($username), $ipAddress, $ipAddress, $data, $data, 1, NULL, NULL, 0, 0, 1, 1, 0, $skype, 0, 0, NULL);
    $query->execute();
    $query->close();
    $this->login($username, $passwordp);
}
