我能够连接到 mysql db，我在其中创建了一个名为 actuator_users 的表。我想知道我错过了什么或做错了什么？我在下面发布了我的功能代码。当我注册用户时，它确认成功，但表格没有更新。

<?php
  require_once('appvars.php');
  require_once('connectvars.php');

  // Connect to the database
  $dbc = mysqli_connect(DB_HOST, DB_USER, DB_PASSWORD, DB_NAME);

  if (isset($_POST['submit'])) {
    // Grab the profile data from the POST
    $username = mysqli_real_escape_string($dbc, trim($_POST['username']));
    $firstname = mysqli_real_escape_string($dbc, trim($_POST['firstname']));
    $lastname = mysqli_real_escape_string($dbc, trim($_POST['lastname']));
    $firmname = mysqli_real_escape_string($dbc, trim($_POST['firmname']));
    $email = mysqli_real_escape_string($dbc, trim($_POST['email']));
    $password = mysqli_real_escape_string($dbc, trim($_POST['password']));
    $password2 = mysqli_real_escape_string($dbc, trim($_POST['password2']));

    if (!empty($username) && !empty($password) && !empty($password2) && ($password == $password2)) {
      // Make sure someone isn't already registered using this username
      $query = "SELECT * FROM attorney_users WHERE username = '$username'";
      $data = mysqli_query($dbc, $query);
      if (mysqli_num_rows($data) == 0) {
        // The username is unique, so insert the data into the database
        $query = "INSERT INTO attorney_users (username, firstname, lastname, firmname, email, password, date) VALUES ('$username', '$firstname', '$lastname', $firmname, $email, SHA('$password'), NOW())";
        mysqli_query($dbc, $query);

        // Confirm success with the user
        echo '<p>Your new account has been successfully created. You\'re now ready to <a href="index.php">log in</a>.</p>';

        mysqli_close($dbc);
        exit();
      }
      else {
        // An account already exists for this username, so display an error message
        echo '<p class="error">An account already exists for this username. Please use a different username.</p>';
        $username = "";
      }
    }
    else {
      echo '<p class="error">You must enter all of the sign-up data, including the desired password twice.</p>';
    }
  }

  mysqli_close($dbc);
?>

更改您的 $query 从

$query = "INSERT INTO attorney_users (username, firstname, lastname, firmname, email, password, date) VALUES ('$username', '$firstname', '$lastname', $firmname, $email, SHA('$password'), NOW())";

至

$password = SHA1($password);  
$query = "INSERT INTO attorney_users (`username`, `firstname`, `lastname`, `firmname`, `email`, `password`, `date`) VALUES ('{$username}', '{$firstname}', '{$lastname}', '{$firmname}', '{$email}', '{$password}', NOW())";

date在 中保留mysql，在列名周围使用 `

$query = "INSERT INTO attorney_users (`username`, `firstname`, 
`lastname`, `firmname`, `email`, `password`, `date`) 
VALUES ('$username', '$firstname', '$lastname', $firmname, 
$email, SHA('$password'), NOW())";

以及为什么要使用mysqli_real_escape_string转义，您可以在此处使用准备好的语句。

编辑

使用它来检查查询中的错误

$data = mysqli_query($dbc, $query) or die(mysqli_error());
