Login Script

[TheJoey]

Im stuck making this login script.

Ive done storing the users on a flat file. Then it recalls only the needed information.

But just then im stuck how do i use the information for a login script

 

Can i use $_POST?

<?php 
$userinfo = file("data.txt");

   echo '<table>';

foreach($userinfo as $key => $val) 
{
   $data[$key] = explode("||", $val);
}

for($k = 0; $k < sizeof($userinfo); $k++);


}

?>

 

Someone suggested

if($d[0] == $username && $d[1] == $password)
{
echo'Loggin successfull' ;

yes. Make a HTML form, POST that information to your PHP script, use $_POST to check whether the details entered match any records in your flat file database. Then redirect the user to where ever. http://www.w3schools.com/php/php_post.asp

The only problem is i dont know where to start.

How do i give variable to my information if it is being retreieved from a .txt file?

 

[MasterACE14]

reading file contents... http://www.tizag.com/phpT/fileread.php

 

The rest is up to you to learn. We can only point you in the right direction. I recommend reading through the PHP tutorials on tizag.com, If anything doesn't make sense look it up on php.net

 

There is some fine examples of how to do various tasks in PHP on the PHP Freaks website.

 

Good Luck

You don't need to add anything to the $_POST array from a text file.

how do i much the login input to that on the data.txt

[trq]

As an example.

 

Username and password combos are stored in a file.

 

foo:bar
bob:whatever
bruce:youok

 

Get you users submitted username and password.

 

$username = $_POST['username'];
$password = $_POST['password'];

 

Now check them against the entires in the file.

 

session_start();
$handle = fopen("users.txt", "r");
$valid = false;
while ($userinfo = fscanf($handle, "%s:%s\n")) {
    list ($name, $pass) = $userinfo;
    if ($username == $name && $password == $pass) {
        $valid = true;
    }
}
fclose($handle);
if ($valid) {
    $_SESSION['logged_in'] = true;
} 
?>

 

[TheJoey]

while ($userinfo = fscanf($handle, "%s:%s\n")) {
    list ($name, $pass) = $userinfo;
    if ($username == $name && $password == $pass) {
        $valid = true;
    }

 

could you explain what %s:%s\n does?

thanks for the example

<?php 
session_start();
$handle = fopen("users.txt", "r");
$valid = false;
while ($userinfo = fscanf($handle, "%s:%s\n")) {
    list ($name, $pass) = $userinfo;
    if ($username == $name && $password == $pass) {
        $valid = true;
    }
}
fclose($handle);
if ($valid) {
    $_SESSION['logged_in'] = true;
echo 'yay ur in';
}
else
{
echo 'You entered a wrong password';
}

?>

i added a echo just to test it seems im always entering a wrong password.
