关于您的信息，请不要立即杀死我，因为我在问一个我没有经验的问题，这就是我问这个问题的原因。
我在下面的占位符附近有个问题。问题是，它的关节表。我对php的了解有限。没有错误，也没有显示任何数据。tq。
/calling for record from table-users and table-useradvert, joined
以下提取
if(isset($_POST['username'])){
$userName = $_POST['username']; $query = "SELECT users.id, users.name, users.username, users.telno, useradvert.id, useradvert.name2, useradvert.color2, useradvert.hobby2, useradvert.radiobtn, useradvert.kupon, useradvert.image, useradvert.image2 ". "FROM users, useradvert ". "WHERE users.id = useradvert.id AND username=?";
$stmt = $conn->prepare($query);
$stmt->bind_param('s',$userName);
$stmt->execute();
$res = $stmt->get_result();
$row = $res->fetch_array();
$_SESSION['id'] = $row['id'];
$_SESSION['name'] = $row['name'];
$_SESSION['username'] = $row['username'];
$_SESSION['telno'] = $row['telno'];
$_SESSION['name2'] = $row['name2'];
$_SESSION['color2'] = $row['color2'];
$_SESSION['hobby2'] = $row['hobby2'];
$_SESSION['radiobtn'] = $row['radiobtn'];
$_SESSION['kupon'] = $row['kupon'];
$_SESSION['image'] = $row['image'];
$_SESSION['image2'] = $row['image2'];
