Header function not redirecting? - php

Question

Please help
I have this php code(below) that creates and inserts a user into database after validating user inputs. I am storing the users input in an array. The problem is
It creates the user and inserts it to database but it does not redirect.
Here's the code
$validation = new Validate();
if($validation->passed()) {
//if success, insert(create) user
try {
$user = new User();
$salt = Crypt::salt(32);
$user->insert(array(
'username' => Accept::get('username'),
'password' => Crypt::make(Accept::get('password'), $salt),
'salt' => $salt,
'name' => Accept::get('name')
));
//After creation, redirect user
header('Location : index.php');
exit();
} catch(Exception $e) { //otherwise display errors
die("ERROR : CAN NOT REGISTER USER ".$e->getMessage());
}
This Code Creates user in database, but it does not redirect. I really don't understand why.

1) Make sure that you do not echo/output anything before the header() function not even blank space
2) write these at top of page to see errors
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
3) try ob_start(); or ob_flush();
ob_start();// at top of page
$validation = new Validate();
if($validation->passed()) {
//if success, insert(create) user
try {
$user = new User();
$salt = Crypt::salt(32);
$user->insert(array(
'username' => Accept::get('username'),
'password' => Crypt::make(Accept::get('password'), $salt),
'salt' => $salt,
'name' => Accept::get('name')
));
//After creation, redirect user
header('Location : index.php');
exit();
ob_flush();
} catch(Exception $e) { //otherwise display errors
die("ERROR : CAN NOT REGISTER USER ".$e->getMessage());
}
