Question

我的代码有问题。它为我提供了“未知专栏”电子邮件＆＃39;在where子句中。我几乎尝试了一切，但我不知道问题是什么。我是初学者，所以请保持温柔：）

任何想法如何解决？

非常感谢

    session_start();
    include('connect.php');
    if(isset($_POST['submit']))
    //when isn't username in form
    if($_POST['firstname'] == '')
    {
        $_SESSION['error']['firstname'] = 'First name is required';
    }
    if($_POST['surname'] == '')
    {
        $_SESSION['error']['surname'] = 'Surname is required';
    }
    //when email isn't in form
    if($_POST['email'] == '')
    {
        $_SESSION['error']['email'] = 'Email is required';
    }
    //check if is email in correct format
    if(preg_match("/^([a-zA-Z0-9])+([a-zA-Z0-9._-])*@([a-zA-Z0-9_-])+([a-zA-Z0-9._-]+)+$/", $_POST['email']))
    {
        //email is in correct format and exist?
        $email = $_POST['email'];
        $sql1 = "SELECT * FROM users WHERE email = '$email'";
        $result1 = mysqli_query($connect, $sql1) or  die(mysqli_error($connect));
        if(mysqli_num_rows($result1) > 0)
        {
            $_SESSION['error']['email'] = 'Email is already used';
        }
    }
    else
    //error for wrong format of email
    {
        $_SESSION['error']['email'] = 'Your email is in wrong format';
    }
    //when isn't password in form
if($_POST['password'] == '')
{
    $_SESSION['error']['password'] = 'Password is required';
}
//when is error -> registration form
/*if(isset($_SESSION['error']))

    header("Location: index.php");
    exit();

    $firstname = mysqli_real_escape_string($connect,$_POST['firstname']);
    $surname = mysqli_real_escape_string($connect,$_POST['surname']);

    $phone_number = mysqli_real_escape_string($connect,$_POST['phone_number']);

    $sql2 = "INSERT INTO users (firstname, surname, email, phone_number, note, password) VALUES ('$firstname', '$surname',
    '$email', '$phone_number', '$note','$password')";
    $result2 = mysqli_query($connect, $sql2) or die('Error: ' .mysqli_error($connect));
