I'm working on a PHP login page. The first page shows two forms, a login and register form and does some form verification. When a user logs in it reads their information out of a text file. The information is listed as
username;password;fname;lname;pagetitle;bgcolor;imgURL
with the end of line occurring after the image. This info then populates a form on the next page so that the user can edit it if they so choose. I have no idea though how to read the line from the file when the user submits the changes and then write it back to the file. I also need to know how I can change the bgcolor and imgURL when these changes are submitted.
My current code is listed below.
<?php
session_start();
$bkcolor = "red";
if(isset($_GET['exit'])){
session_unset();
session_destroy();
}
if(isset($_SESSION['loggedin']) && $_SESSION['loggedin'] == true){
?>

echo"Hello, ".$_SESSION['fname']. " " .$_SESSION['lname']."!";
//echo $_SESSION['image'];
