Hi guys

I have been receiving this error for a while was wondering if anyone would be so kind to assist me in solving this problem.

Script below:

<? session_start();?>
<?php
require_once('includes/authenticate.class.php');
$auth = new Authenticate();
$OppLogin_txtEmail=$_REQUEST['OppLogin_txtEmail'];
$OppLogin_txtPwd=$_REQUEST['OppLogin_txtPwd'];
$OppLogineleSubmit=$_REQUEST['OppLogineleSubmit'];
$go=$_REQUEST['go'];
if($go=="yes"){
if($OppLogin_txtPwd==""){
$err="yes";
$err_msg.="<li>Password is required </li><br/> ";
}
if($OppLogin_txtEmail==""){
$err="yes";
$err_msg.="<li>Valid IBO NO is required </li><br/> ";
}
if($err!="yes"){
if($auth->login($OppLogin_txtEmail, $OppLogin_txtPwd)){
$auth_info = $auth->getAuthInfo();
$_SESSION['associateslogin'] = $auth_info['email_address'];
$_SESSION['user_type'] = $auth_info['type'];
header('location:associates/index.htm');
}else{
$err="yes";
$err_msg = 'Authentication failed. Please re-enter and try again.';
}
}
}
?>

Authenticate Class Script:

<?php
class Authenticate{

private $db = null;
private $db_settings = array();
private $ibo_info = array();

public function __construct(){

require_once('classes/config.class.php');
$config = new Config();
$db_settings = $config->getDBInfo();
$this->db_settings = $db_settings;

$db = mysql_connect('localhost','edgest_1', 'sp9jXgy8');
mysql_select_db('edgest_db1', $db);

$this->db = $db;
return true;

}

//Authenticates a user against a db entry
public function authenticateVistor($access_code){

$db = $this->db;

//Retrieve the db entry
$sql = 'SELECT `ibo_number`, `ibo_name`, `email_address` FROM `user_info` WHERE `ibo_number`="'. $access_code .'"';

//Query the db
$query = mysql_query($sql, $db);

//Check to see if a result was returned
$num_rows = mysql_num_rows($query);

if($num_rows > 0){

//Retrieve the returned resultset and assign local copies of each piece of information
$row = mysql_fetch_assoc($query);
$this->setAuthInfo($row);

return true;

}else{

return false;

}

}

public function getAuthInfo(){

return $this->ibo_info;

}

//Sets the member copy of the db retrieved info
public function setAuthInfo($info){

$this->ibo_info = $info;

}

public function isAuthenticated(){

if(!(isset($_SESSION['ibo_number']))){

return false;

}else{

return true;

}

}

public function login($ibo_number, $password){

$db = $this->db;

$sql = 'SELECT `ibo_number`,`type` FROM `logins` WHERE `ibo_number`="'.$ibo_number.'" AND `password`="'.$password.'"';

//Query the db
$query = mysql_query($sql, $db);

//Check to see if a result was returned
$num_rows = mysql_num_rows($query);

if($num_rows > 0){

//Retrieve the returned resultset and assign local copies of each piece of information
$row = mysql_fetch_assoc($query);
//$this->setAuthInfo($row);

return true;

}else{

return false;

}
}

public function logout(){

session_destroy();
header('location:index.php');
exit();

}


}
?>

Everytime I try create a session for the user after he has successfully logged in I get the following error message:

"Cannot send session cache limiter - headers already sent Error"

Thank you.

headers already sent message usually indicates that something has already been sent prior to your request to start a session. sometimes that can be you have sent some data, sometimes it means you have something wrong with the script and it is sending hiden or blank/spaces to the user.

at first glance I think your problem lies in
I'd move the session start into the start of the <?PHP block
eg
