Question

Hy :)基本上我正在努力解决与这个男孩相同的问题：PHP Sign-up Form Not Working - 我认为我们正在通过相同的youtube教程：D

不幸的是我无法评论这个话题，这就是为什么我要开一个新主题。问题是我的signup.php应该是正确的（至少输入正确吗？），但我很可能会忽视这些事情：

Thi signup.php文件：

<?php
include_once 'header.php';
 ?>


  <section class="main-container">
<div class="main-wrapper">
  <h2>Sign up</h2>
  <form class="signup-form" action="includes/signup.inc.php" method="POST">
    <input type="text" name="first" placeholder="Firstname">
    <input type="text" name="last" placeholder="Lastname">
    <input type="text" name="email" placeholder="E-Mail">
    <input type="text" name="uid" placeholder="Username">
    <input type="password" name="pwd" placeholder="Password">
    <button type="submit" name="submit">Sign up</button>
  </form>
</div>
  </section>

  <?php
  include_once 'footer.php';
   ?>

当我输入信息时，它会一直显示我signup.php？signup = empty。

if (isset($_POST['submit'])) {
  include_once 'dbh.inc.php';

  $first = mysqli_real_escape_string($conn, $_POST['first']);
  $last = mysqli_real_escape_string($conn, $_POST['last']);
  $email = mysqli_real_escape_string($conn, $_POST['email']);
  $uid = mysqli_real_escape_string($conn, $_POST['uid']);
  $pwd = mysqli_real_escape_string($conn, $_POST['pwd']);

//Error Handlers
//Check for empty fieldset

if (empty($first) || empty($last) || empty($email) || empty($uid) || empty($pwd)) {
  header("Location: ../signup.php?signup=empty");
  exit();
}

else {
  //Check if input characters are valid
  if (!preg_match("/^[a-zA-Z]*$/", $first) || !preg_match("/^[a-zA-Z]*$/", $last)) {
    header("Location: ../signup.php?signup=invalid");
    exit();
  }
  else {
    // Check if E-Mail is valid
    if (!filter_var($email, FILTER_VALIDATE_EMAIL)) {
      header("Location: ../signup.php?signup=email");
      exit();
    }
    else {
      $sql = "SELECT * FROM users WHERE user_uid='$uid'";
      $result = mysqli_query($conn, $sql);
      $resultCheck = mysqli_num_rows($result);

      if ($resultCheck > 0) {
        header("Location: ../signup.php?signup=usertaken");
        exit();
      }

      else {
        // Hashing the Password (verschlüsseln)...
        $hashedPwd = password_hash($pwd, PASSWORD_DEFAULT);
        //Insert the User into the Database
        $sql = "INSERT INTO users (user_first, user_last, user_email, user_uid, user_pwd) VALUES ('$first', '$last', '$email', '$uid', '$hashedPwd');";
        mysqli_query($conn, $sql);
        header("Location: ../signup.php?signup=success");
        exit();
      }

    }
  }
}

}
else {
  header("Location: ../signup.php");
  exit();
}

非常感谢您对此提出的任何暗示。最好，克里斯

更新：

在代码中添加以下内容时：

exit(var_dump(empty($first), empty($last), empty($email), empty($uid), empty($pwd)));

它返回

bool(true) bool(true) bool(true) bool(true) bool(true)
