Login Script

DestinatioN · 23. April 2014, 11:54

Hallo,
ich habe habe mich mal wieder mit PHP befasst um ein bisschen was dazu zu lernen und meinen Horizont zu erweitern.
Jetzt habe ich mir dieses Login Panel angeschaut.

Davon habe ich die Demo verwendet und ein bisschen verändert.
So das dies entstanden ist.

index.php

PHP-Quellcode

<?php
define('INCLUDE_CHECK',true);
//require 'connect.php';
require 'functions.php';
// Those two files can be included only if INCLUDE_CHECK is defined
session_name('Login');
// Starting the session
session_set_cookie_params(2*7*24*60*60);
// Making the cookie live for 2 weeks
session_start();
if($_SESSION['id'] && !isset($_COOKIE['Remember']) && !$_SESSION['rememberMe'])
{
// If you are logged in, but you don't have the Remember cookie (browser restart)
// and you have not checked the rememberMe checkbox:
$_SESSION = array();
session_destroy();
// Destroy the session
}
if(isset($_GET['logoff']))
{
$_SESSION = array();
session_destroy();
header("Location: index.php");
exit;
}
if($_POST['submit']=='Login')
{
// Checking whether the Login form has been submitted
$error = array();
// Will hold our errors
if(!$_POST['username'] || !$_POST['password'])
$error[] = 'Alle Felder müssen ausgefüllt sein!';
if(!count($error))
{
$_POST['username'] = mysql_real_escape_string($_POST['username']);
$_POST['password'] = mysql_real_escape_string($_POST['password']);
$_POST['rememberMe'] = (int)$_POST['rememberMe'];
// Escaping all input data
$row = mysql_fetch_assoc(mysql_query("SELECT id,user FROM members WHERE user='{$_POST['username']}' AND password='".md5($_POST['password'])."'"));
if($row['user'])
{
// If everything is OK login
$_SESSION['user']=$row['user'];
$_SESSION['id'] = $row['id'];
$_SESSION['rememberMe'] = $_POST['rememberMe'];
// Store some data in the session
setcookie('Remember',$_POST['rememberMe']);
}
else $error[]='Falscher Username oder Password!';
}
if($error)
$_SESSION['msg']['login-error'] = implode('<br />',$error);
// Save the error messages in the session
header("Location: index.php");
exit;
}
else if($_POST['submit']=='Register')
{
// If the Register form has been submitted
$error = array();
if(strlen($_POST['username'])<4 || strlen($_POST['username'])>32)
{
$error[]='Dein Benutzername ist zu kurz oder zu lang!!';
}
if(preg_match('/[^a-z0-9\-\_\.]+/i',$_POST['username']))
{
$error[]='Dein Benutzername enthält unerlaubte zeichen!';
}
if(!checkEmail($_POST['email']))
{
$error[]='E-Mail Adresse überprüfen!';
}
if(!count($error))
{
// If there are no errors
$password = substr(md5($_SERVER['REMOTE_ADDR'].microtime().rand(1,100000)),0,6);
// Generate a random password
$_POST['email'] = mysql_real_escape_string($_POST['email']);
$_POST['username'] = mysql_real_escape_string($_POST['username']);
// Escape the input data
mysql_query(" INSERT INTO members(user,password,email,regIP,date)
VALUES(
'".$_POST['username']."',
'".md5($password)."',
'".$_POST['email']."',
'".$_SERVER['REMOTE_ADDR']."',
NOW()
)");
if(mysql_affected_rows($link)==1)
{
send_mail( 'demo-test@tutorialzine.com',
$_POST['email'],
'Registration System Demo - Your New Password',
'Your password is: '.$password);
$_SESSION['msg']['reg-success']='We sent you an email with your new password!';
}
else $error[]='Der Benutzername existiert bereits!';
}
if(count($error))
{
$_SESSION['msg']['reg-error'] = implode('<br />',$error);
}
header("Location: index.php");
exit;
}
$script = '';
if($_SESSION['msg'])
{
// The script below shows the sliding panel on page load
$script = '

$("div#panel").show();

Ich möchte aber nicht das ein Passwort per Email versendet wird sondern das es bei der Registrierung selber ausgewählt werden kann.
Bei der Registrierung soll es aber doppelt angeben werden und überprüft werden ob sie überein stimmen.

Ich hoffe mir kann jemand helfen.

Ich denke du solltest ein Login-Scrpt prinzipiell schonmal nicht auf etwas fremden aufbauen.
Die von dir gewünschten Funktionen sind sehr einfach. Daher solltest du dich lieber etwas mit PHP befassen, selber was prockeln und dich damit hier zur Not melden, anstatt ne fertige Demo zu nehmen und da was ändern zu wollen, ohne jegliche Kenntnisse.

Grundkenntnisse habe ich ja nur mit dem Passwort überprüfen klappt einfach nicht so wie ich es probiert habe.

Es klappt wie gesagt nur bei der Passwort funktion
