Creating a login using CSV's

**tech_support** · 11-23-2006, 05:52 AM

Is there a way to create a login system using a CSV table?

That can be done the file operations supported by the PHP without much difficulty.

I've done that once earlier but later changed that to database rather than using CSV.

You mean the information stored in the CSV file or the file itself?

I have tried it once too. It gives a lot of pain when you need to update the values.

I don't think the OP ever posted that(at least I can't see that in the original post).

Can you give me the file? I could do it myself but I just haven't got the time.

The information stored in the CSV file.

Ok, here it is. It needs a little bit of tweaking(sorry I am a PHP newbie).

login.php

Code:

<?php
session_start();
?>
<html>
<head>
</head>
<body>
<?php
if(isset($_GET['login'])){
if(isset($_SESSION['logged'])){
echo 'You cannot login in when you are logged in already.';
} else {
?>
<form name="login" method="POST" action="processes.php">
Username: <input type="text" name="username"><br>
Password: <input type="password" name="password"><br>
<input type="submit"><br>
<a href="?register=true">Please Register Here</a>
</form>
<?php
}
} else if(isset($_GET['register'])){
if(isset($_SESSION['logged'])){
echo 'You cannot register when you are logged in.';
} else {
?>
<form name="login" method="POST" action="register.php">
Username: <input type="text" name="username"><br>
Password: <input type="password" name="password"><br>
Email: <input type="text" name="email"><br>
<input type="submit">
</form>
<?php
}
} else {
if(isset($_SESSION['logged'])){
echo 'You don\'t have any previleges here.';
} else {
?>
Please <a href="?login=true">Login</a><br>
OR<br>
Register <a href="?register=true">here</a>
<?php
}
}
?>
</body>
</html>

processes.php

Code:

<?php

# function newfile, by Twey of dynamicdrive

function newfile($filename){
$lines = file($filename);
$config = array();
for($i = 1; $i < count($lines); ++$i)
$config[substr($lines[$i], 0, strpos($lines[$i], ':'))] = substr($lines[$i], strpos($lines[$i], ':') + 1, -1); // -2 for a Windows host
return $config;
}
if(isset($_GET['logout'])){
unset($_SESSION['logged']);
}
//print_r(newfile('users.php'));
$users = newfile('users.php');
//echo $test['test1'];
$username = $_POST['username'];
$password = $_POST['password'];
list($pass,$email) = explode(',', $users[$username]);
if(isset($users[$username]) && md5($password) == $pass){
session_start();
$_SESSION['logged'] = $username;
echo 'Hello you are registered.<br>';
echo 'Click <a href="somepage.php">here</a> to go to some other page.<br>';
echo 'Click <a href="processes.php?logout=true">here</a> to logout.<br>';
echo 'Your email address is '.$email;
} elseif(!isset($users[$username]) && md5($password) != $users[$username]) {
echo 'Username or password Incorrect';
}
if(isset($_SESSION['logged'])){
echo '<br>test';
}
?>

register.php

Code:

<?php
function newfile($filename){
$lines = file($filename);
$config = array();
for($i = 1; $i < count($lines); ++$i)
$config[substr($lines[$i], 0, strpos($lines[$i], ':'))] = substr($lines[$i], strpos($lines[$i], ':') + 1, -1); // -2 for a Windows host
return $config;
}
$users = newfile('users.php');
$user = $_POST['username'];
$pass = md5($_POST['password']);
$email = $_POST['email'];
if(isset($user) && isset($pass)){
if(array_key_exists($user, $users)){
echo 'Username Taken';
} else {
$f = fopen('users.php', 'a');
fwrite($f, $user.":".$pass.",".$email."\n");
fclose($f);
echo 'Successfully registered!!! Please click here to login.<br><a href="login.php?login=true">Login</a>';
}
} else {
echo 'No Username or password';
}
?>

somepage.php

Code:

<?php
session_start();
if(isset($_SESSION['logged'])){
echo 'You are still logged in';
echo '<br><a href="processes.php?logout=true">Logout</a>';
} else {
echo 'Please login first';
}
?>

users.php

Code:
