Help Adding Users

pawertiger · November 7, 2012

So I found this code from a website to use as a login, but it can only allow one user right now with the code given. Anyone know how to add multiple users?

First code (where the usernames and passwords for users are)

<?php
define("ADMINUSER", "adf");
define("ADMINPASSWORD", "adf");
define("ADMINHOME", "index.php");
?>

2nd code

Code after clicking submit on login

<?php
session_start();
include("sec.php");
if (($user==ADMINUSER) && ($pass==ADMINPASSWORD))
{
$_SESSION['myuser'] = "jd";
header("Location: welcome.php");
}
else
{
header("Location: auth.php?flag=wrong");
}
?>

3rd code

Login one with the username and password input

<?php
session_start();
//This script (PHP Login Without MySql v1.2)
//was designed by Aarmale.  If you like this
//script, comment at the SourceForge page!!
//-------------------------------------
require 'include.php';// change variables such as username and pass @ include.php!!!!!
//-------------------------------------
// if the submit button is pressed or the SESSION named login exists...
if (isset($_POST['submit']) || isset($_SESSION['login'])) {
// if the SESSION exists... (this is here if the submit button is pressed)
if (isset($_SESSION['login'])) {
// if the SESSION equls the MD5 hash...
if ($_SESSION['login'] == $hash) {
//say your info!
echo "
<p align=center>
<font size=4>Logged In!</font>
</p><p align=left>
<a href=logout.php>Logout. Note, this may not work. Exit browser/clear cookies to log out.</a><BR><BR></p>";
} else {
//if the SESSION exists, but does not equal the hash say...
echo "Bad SESSION. Clear them out and try again.";
}
} else {
//info
// if the submit button is pressed, but the SESSION dose not exist, go through these steps...
if ($_POST['user'] == $user && $_POST['pass'] == $pass){
//user = your username & password = your password. acess granted. add SESSIONs and refresh.
$_SESSION["login"] = $hash;
header("Location: $_SERVER[php_SELF]");
} else {
echo "incorrect user/pass";
}
}
}
else {
//if none of the if/else statemants happen, show the login form...
print "<form action=";
echo "$self ";
print "method=post>Login<fieldset><BR>Username: <input type=text name=user><BR>
Password: <input type=password name=pass><BR><input type=submit name=submit value=submit></fieldset></form>";
}
?>   <br/>   <br/><br/>

<?php
if ($ads == TRUE)  {   //if you set ads on (in includes.php) insert code below...
?>
 <!-- Start ads code-->
  <script type="text/javascript">
google_ad_client = "pub-<?php echo "$pub_code" ?>";
google_ad_width = 728;
google_ad_height = 90;
google_ad_format = "728x90_as";
google_ad_type = "text";
google_color_border = "FFFFFF";
google_color_bg = "FFFFCC";
google_color_link = "C3D9FF";
google_color_text = "000000";
google_color_url = "008000";
</script><script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"></script>
   <?php
 } else {
 }

   ?>

Thanks in advance!

Wow I copied the wrong codes......

Please view code from here. Sorry.

Login page:

<head>
<style type="text/css">
<!--
body {
font: 10px Verdana, Arial, Helvetica, sans-serif;
text-decoration: none;
}
td {
font: 10px Verdana, Arial, Helvetica, sans-serif;
text-decoration: none;
}
-->
</style>
</head>
<body>
<form method="post" name="auth" action="success.php">
<table width="400" border="0" cellspacing="4" cellpadding="0">
<tr>
<td width="150" align="right">User Name: </td>
<td><input name="user" type="text" id="user"></td>
</tr>
<tr>
<td width="150" align="right">Password: </td>
<td><input name="pass" type="password" id="pass"></td>
</tr>
<tr>
<td width="150" align="right"> </td>
<td><input type="reset" name="Submit2" value="Clear">
<input type="submit" name="Submit" value="Submit"></td>
</tr>
</table>
</form>
<br>
<table width="400" border="0" cellspacing="4" cellpadding="0">
<tr>
<td align="center"><?
if ($flag==wrong)
{
echo "Invalid User Name or Password";
}
?>
 <?
if ($flag==out)
{
echo "Logged Out";
}
?></td>
</tr>
</table>
</body>

Code 2:

Users

<?php
define("ADMINUSER", "tno");
define("ADMINPASSWORD", "tno");
define("ADMINHOME", "index.php");
?>

Code 3:

When someone clicks the submit from the first code

<?php
session_start();
include("sec.php");
if (($user==ADMINUSER) && ($pass==ADMINPASSWORD))
{
$_SESSION['myuser'] = "jd";
header("Location: welcome.php");
}
else
{
header("Location: auth.php?flag=wrong");
}
?>

You would use an array with the array key/index being the username and the value being the password.

$admin['user_name_1'] = 'password_1';
$admin['user_name_2'] = 'password_2';

The logic test would then become -

if(isset($admin[$user]) && $pass==$admin[$user])
