I guess this is a 3-part post so i don't end up polluting the forums...
1) Alrighty. Let me get started on the right foot here by saying hi to everyone. I'm a New CI guy here ( >1 week) and have been loving every minute of it...until
Code:
A PHP Error was encountered
Severity: Warning
Message: Cannot modify header information - headers already sent by (output started at CodeIgniter\system\application\controllers\home.php:8)
Filename: helpers/url_helper.php
Line Number: 487
dun dun dun...
the funny thing is the $echo (on line 8 below) prints fine, and then the error follows.
Quote:let me preface the situation :
I'm using FreakAuth Light (which is the topic of the second question) and the logins work alright and stuff...so maybe that has something to do with all this?
so i investigated:
\CodeIgniter\system\application\controllers\home.php
Code:
1<?php
2class Home extends Controller {
3
4
5 function Home() {
6 parent::Controller();
7 $this->load->helper('url');
8 echo 'how is this possible?!';
if(isValidUser()) {
}else{
redirect('/welcome/');
}
}
function index() {
if (isValidUser()) {
$data['username'] = $this->db_session->userdata('user_name');
$data['user_id'] = $this->db_session->userdata('id');
$this->load->view('home_view', $data);
}else{
redirect('/welcome/');
}
}
}
?>
and \CodeIgniter\system\helpers\url_helper.php
Code:
469 /**
* Header Redirect
*
* Header redirect in two flavors
*
* @access public
* @param string the URL
* @param string the method: location or redirect
* @return string
*/
479 if (! function_exists('redirect'))
{
function redirect($uri = '', $method = 'location')
{
switch($method)
{
case 'refresh' : header("Refresh:0;url=".site_url($uri));
break;
487 default : header("Location: ".site_url($uri));
break;
}
exit;
}
492 }
so all I did was use the usual redirect() in my controller...what did i do wrong??
all I'm trying to do is write out a redirect that basically goes
Code:
if you're logged in
{
you're going to /home/
}but if you're not{
take a look at our schnazzy welcome page. go sign up there. its good for you.
}

second question:
I'm loving that there are so many different libraries that extend the capabilities of CI. But in my dabbling i've found that FreakAuth works better than the BackendPro library also available. Does anyone have a suggestion over which library would work for a site that would have to accommodate many many users.
second.5 question:
why isn't there a resource for libraries like FreakAuth and such that have just a listing of its functions and what each does and returns? I haven't found anything like that on FreakAuth and barely have found something for CI...unless i've been missing something all this time.
third question:
has anyone here completed a user-driven site using the CI framework? all i've been seeing are blogs and personal sites. I haven't yet seen a site where groups of people generate the content, as opposed to the CI coder who owns the site. just wondering.
thanks, again to anyone who has taken the time to read this, and even lend a helping hand...or at least a pointed finger in the right direction. I'm eager to learn CI, and I know learning it will take me a long way.
