Currently I have a form that collects basic user information - first and last name, email and password. This is being stored in a txt file. Here is the code that is processing the information into the txt file.

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Create Process</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
</head>

<body>
<?php

//Escapes and enquotes variables
function clean($var){
    return trim(addslashes($var));
}
//Variable declaration

    $fname = clean($_POST['first_name']);
    $lname = clean($_POST['last_name']);
    $email = clean($_POST['email_address']);
    $pw = clean($_POST['password']);

//Declare the file
    $file = "/staff/seebetra/homepage/ciss225/registered_users.txt";

//Open File in append mode
 $fp = fopen ($file, "a+");

//Append Data to file	 
 fwrite($fp, $email);
 fwrite($fp, ":");
 fwrite($fp, $pw);
 fwrite($fp, ":");
 fwrite($fp, $fname);
 fwrite($fp, ":");
 fwrite($fp, $lname);
 fwrite($fp, ":");

 echo 'Done<br />';
 echo $fname;
 echo ', your account has been created';



// Close the file
fclose($fp);	


?>
</body>
</html>

Once you are registered, you will be able to log in. Right now once I confirm login data - they will go to a wlecome page as this is a work in progress. The login is process in a login_process.php that will call in the function from a file called library.pinc. The problem that I am having is that it never finds my data. My guess is that it has something to do with how it is being set up in the txt file but I am not sure. I know a database is a better option there but this is what I have to work with at this time.

Here is the code for the login_process:

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<title>Login Process</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
</head>

<body>
<?php 
include('/staff/seebetra/homepage/ciss225/library.pinc'); 

if(!isset($_POST['submit']))
{
getLogin($username, $password);
}

?> 

</body>
</html>

Here is the function in library.pinc

<?php
function getLogin($username, $password)
{

$email = trim($_POST['email']);
$pass = trim($_POST['pass']);

$file = "/staff/seebetra/homepage/ciss225/registered_users.txt";
$lines = file($file);
$logged = FALSE;
foreach($lines as $line)
{
if(preg_match("/^.+?:.+?:".preg_quote($email).":".preg_quote($pass)."$/s", trim($line)))
{
	list($first, $last, $f_email, $f_pass) = explode(":", trim($line));
	echo "Hello ".$first." ".$last."!";
	$logged = TRUE;
	break;
}
}
if(!$logged)
echo "Sorry, you didn't match!";
}
?>

Can anyone help me with this??

As you expect to read the data as separate lines you need to write it as separate lines.

 fwrite($fp, $email);
 fwrite($fp, ":");
 fwrite($fp, $pw);
 fwrite($fp, ":");
 fwrite($fp, $fname);
 fwrite($fp, ":");
 fwrite($fp, $lname);
 fwrite($fp, "\n");        // write a newline at end of each new record

or even

fwrite ($fp, "$email:$pw:$fname:$lname\n");

Thanks for your help.

I did change the code to write to file to be

fwrite ($fp, "$email:$pw:$fname:$lname\n");

but it still is telling me I have not matches when I know I do.

I really think the problem is in the function -

<?php

function getLogin($username, $password)

{

$email = trim($_POST['email']);

$pass = trim($_POST['pass']);

$file = "/staff/seebetra/homepage/ciss225/registered_users.txt";

$lines = file($file);

$logged = FALSE;

foreach($lines as $line)

{

if(preg_match("/^.+?:.+?:".preg_quote($email).":".preg_quote($pass)."$/s", trim($line)))

{

list($first, $last, $f_email, $f_pass) = explode(":", trim($line));

echo "Hello ".$first." ".$last."!";

$logged = TRUE;

break;

}

if(!$logged)

echo "Sorry, you didn't match!";

}

?>

Any other suggestions?
