Ik heb een ergens mijn best op gedaan en iets af kunnen maken. Het is een simpel inlog systeem. De volgende dingen kan je er mee doen:
Inloggen
Uitloggen
Registreren
Op de indexpagina zie je als je bent ingelogd. Op bijna iedere pagina zit wel een knop op uit te loggen
Index.php
<?php
include 'config.php';
if (isset($_SESSION['username'])) {
echo "Hallo, u bent ingelogd als: ". $_SESSION['username']. ". <a href='logout.php'>Uitloggen</a>";
} else {
echo "U bent nog niet ingelogd. <a href='login.php'>Inloggen</a>";
}
?> Config.php
<?php
error_reporting(0);
session_start();
// Standaard instellingen
$gen['sql'] = true;
$gen['connect'] = 'pconnect'; //Connect of pconnect. Advies: pconnect
//SQL gegevens
$sql['host'] = 'localhost';
$sql['user'] = 'root';
$sql['pass'] = '---------';
$sql['data'] = '---------';
if ($gen['sql'] == true AND $gen['connect'] == 'connect') {
mysql_connect ($sql['host'], $sql['user'], $sql['pass']) or die(mysql_error());
mysql_select_db ($sql['data']) or die(mysql_error());
} elseif ($gen['sql'] == true AND $gen['connect'] == 'pconnect') {
mysql_pconnect ($sql['host'], $sql['user'], $sql['pass']) or die(mysql_error());
mysql_select_db ($sql['data']) or die(mysql_error());
}
//Site instellingen
$basic['site_naam'] = 'Koen Hollander';
$basic['register'] = 'on'; //on / off
$basic['login'] = 'on'; //on / off
$basic['direct_actief'] = '1'; //1=ja 0=nee

Ik ben er zelf best wel trots op, maar wat vinden jullie er van?
P.s. Dit is helemaal, 100% zelf gemaakt
