Boa tarde imasters, alguém me ajuda nisso:

 

 

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at C:\xampp\htdocs\guia\pagina\login.php:1) inC:\xampp\htdocs\guia\pagina\login.php on line 4

<?php require_once('../Connections/conexao.php'); ?>
<?php
if (!isset($_SESSION)) {
  session_start();
}

$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
  $_SESSION['PrevUrl'] = $_GET['accesscheck'];
}

if (isset($_POST['email'])) {
  $loginUsername=$_POST['email'];
  $password=$_POST['pwd'];
  $MM_fldUserAuthorization = "";
  $MM_redirectLoginSuccess = "sucesso.php";
  $MM_redirectLoginFailed = "error.php";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_conexao, $conexao);
  
  $LoginRS__query=sprintf("SELECT login, senha FROM cliente WHERE login=%s AND senha=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text")); 
   
  $LoginRS = mysql_query($LoginRS__query, $conexao) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);
  if ($loginFoundUser) {
     $loginStrGroup = "";
    
	if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}


    $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;	      

    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];	
    }
    header("Location: " . $MM_redirectLoginSuccess );
  }
  else {
    header("Location: ". $MM_redirectLoginFailed );
  }
}
?>

OBRIGADO!

O quê você quer fazer com o session?

[Alaerte Gabriel 662]

O session start deve estar sempre acima, inverta:

<?phpif (!isset($_SESSION)) {session_start();}
<?php require_once('../Connections/conexao.php'); ?>
