How to go to account folder using session in php - php

Question

The below code may / may not have many hidden errors.
What I want:- I have session which results as if a user is at index.php and is logged, it will redirect to its account folder.
What I got:- In index.php I got see image.
How account folder is prescribed:-
Suppose there are two users, having uname as trial & demo
So the account folder for trial will be http://localhost/Ebooks/new/trial & for demo it will be http://localhost/Ebooks/new/demo
Means account folders are based on their uname
uname is nothing but username
For getting the result I tried:-
index.php
<?php
session_start();
require_once 'class.user.php';
$user_login = new USER();
if($user_login->is_logged_in()!="")
{
$user_login->redirect($uname);
}
if(isset($_POST['btn-login']))
{
$uname = trim($_POST['txtuname']);
$upass = trim($_POST['txtupass']);
if($user_login->login($uname,$upass))
{
$user_login->redirect($uname);
}
}
?>
class.user.php
public function is_logged_in()
{
if(isset($_SESSION['userSession']))
{
return true;
}
}
public function redirect($uname)
{
try{
$stmt = $this->conn->prepare("SELECT * FROM tbl_users WHERE userName=:username");
$stmt->execute(array(":username"=>$uname));
header("Location: $uname");
} catch (Exception $e) {
die('Error! '.$e->getMessage());
}
}
public function logout()
{
session_destroy();
$_SESSION['userSession'] = false;
}
But I get the result as see image.
I request to sort out my problem!
If my error is solved please do not consider the problem is solved. I want basically How to go to account folder using session in PHP, but this may have many hidden problems.

Answer 1

You need a catch if you are goiung to try something:
public function redirect($uname)
{
try{
$stmt = $this->conn->prepare("SELECT * FROM tbl_users WHERE userName=:username");
$stmt->execute(array(":username"=>$uname));
header("Location: $uname");
} catch (Exception $e) {
die('Error! '.$e->getMessage());
}
}
Handle any errors however you will in the catch area.

Answer 2

You need catch block as well with try. I assume you use PDO, so working solution would be following.
public function redirect($uname) {
try{
$stmt = $this->conn->prepare("SELECT * FROM tbl_users WHERE userName=:username");
$stmt->execute(array(":username"=>$uname));
}
catch(PDOException $error) {
return $error->getMessage();
}
header("Location: $uname");
}
