Foutmelding bij inloggen admin + contactformulier

chakar · 31 mrt 2011

Hallo, ik heb nog een probleem met 2 pagina's bij het benaderen van de database.
Ik krijg de volgende melding op de admin pagina:

Warning: session_start() [function.session-start]: Cannot send session cookie - headers already sent by (output started at /home/carteblanc/domains/carteblanchepw.be/public_html/common/db.php:25) in /home/carteblanc/domains/carteblanchepw.be/public_html/common/ac.php on line 5

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/carteblanc/domains/carteblanchepw.be/public_html/common/db.php:25) in /home/carteblanc/domains/carteblanchepw.be/public_html/common/ac.php on line 5

Weet iemand wat dit betekend ?

Hierbij de code van de pagina db.php:

Code:

<?php

$dbhost = "localhost";
$db = "carteblanc_carte";
$dbuser = "carteblanc_carte"; 
$dbpass = "walter123"; 

function dbConnect($db="") { 
   global $dbhost, $dbuser, $dbpass; 
    
   $dbcnx = mysql_connect("$localhost", "$dbuser", "$dbpass") 
       or die(mysql_error());

   if ($db!="" and !mysql_select_db($db)) 
       die(mysql_error()); 
    
   return $dbcnx; 
} 

?>

En dit is de ac.php pagina

Code:

<?php // ac.php
include_once 'common.php';
include_once 'db.php';

session_start();

$uid = isset($_POST['uid']) ? $_POST['uid'] : $_SESSION['uid'];
$pwd = isset($_POST['pwd']) ? $_POST['pwd'] : $_SESSION['pwd'];


if(!isset($uid)) {
?>

Een van je includes heeft waarschijnlijk output. Je mag geen output sturen voor je session_start aanroept, geen <html>, geen spatie, geen tekst, NIKS.

Makkelijkste oplossing is om session_start() dus nog een paar regels hoger te zetten, direct na de <?php
