Check if user request to register too than redirect, update code like below :
检查用户是否请求注册而不是重定向，更新如下代码：
session_start();
include('_includes/config.php');
include('_includes/db.php');
if(isset($_POST['register'])){
$_SESSION['uname'] = $_POST['uname'];
$_SESSION['fname'] = $_POST['fname'];
$_SESSION['lname'] = $_POST['lname'];
$_SESSION['email'] = $_POST['email'];
$_SESSION['address'] = $_POST['address'];
$_SESSION['postal'] = $_POST['postal'];
$_SESSION['pass'] = $_POST['pass'];
$_SESSION['con-pass'] = $_POST['con-pass'];
}
if(strlen($_POST['uname'])<3 && isset($_POST['register'])){ // add && isset($_POST['register'])
header("Location:register.php?err=" . urlencode("The username must be at least 3 characters long"));
die();
}
Note:at all i'm suggest you don't redirect user to show error message if codes in some file! you can store error message in vars and check if error var is not empty echo it!
注意：如果某些文件中有代码，我建议您不要重定向用户以显示错误消息！您可以将错误消息存储在 vars 中并检查错误 var 是否不为空回显它！
session_start();
include('_includes/config.php');
include('_includes/db.php');
$error = ''; //add this var
if(isset($_POST['register'])){
$_SESSION['uname'] = $_POST['uname'];
$_SESSION['fname'] = $_POST['fname'];
$_SESSION['lname'] = $_POST['lname'];
$_SESSION['email'] = $_POST['email'];
$_SESSION['address'] = $_POST['address'];
$_SESSION['postal'] = $_POST['postal'];
$_SESSION['pass'] = $_POST['pass'];
$_SESSION['con-pass'] = $_POST['con-pass'];
}
if(strlen($_POST['uname'])<3 && isset($_POST['register'])){ // add && isset($_POST['register'])
/*header("Location:register.php?err=" . urlencode("The username must be at least 3 characters long"));
die();*/
$error = 'this is error message';
}
//add below code anywhere you want show error
if($error){
echo $error;
}
