PHP Session is ending unexpectedly

I have got a session up and running in PHP, but for some reason when I click a page sometimes, the session seems to end unexpectedly. FOR EXAMPLE: I have a simple user login page (just username): INDEX.PHP

<h1>User Sign-In:</h1>

<form name="login" action="main.php" method="post">
    Username: <input type="text" name="username">
    <input type="submit" value="Submit">
</form>

MAIN.PHP

<?php
session_save_path(trim(`echo ~`).'/php_sessions'); session_start();
$_SESSION['username']= $_POST["username"];
$username = $_SESSION['username'];

if(isset($_SESSION['username']))
    {
    }
else
    header('Location:./index.php');
?>

<body>

<?php
    echo "Hello, your username is: " . $_SESSION["username"];
?>
<a href="./main.php">Store</a> | <a href="./basket.php">Basket</a> | <a href="./about.php">About</a> | <a href="./logout.php">Logout</a>


<form name="select1"action="" method="GET">
<select name="higherorlower">
    <option value="All">All</option>
    <option value="greaterthan">Greater Than</option>
    <option value="lowerthan">Lower Than</option>
</select>
Price:<input type="text" name="price"/>
<input type="submit" name="submit" value="Submit" />

BASKET.PHP

<?php
session_save_path(trim(`echo ~`).'/php_sessions'); session_start();
$username = $_SESSION['username'];

if(isset($_SESSION['username']))
    {
    }
else
    header('Location:.');
?>

<body>
<?php
    echo "Hello, your username is: " . $_SESSION["username"];
?>


<a href="./main.php">Store</a> | <a href="#">Basket</a> | <a href="./about.php">About</a> | <a href="./logout.php">Logout</a>

<h2>
You're currently on the basket page!
</h2>

So say I type in my username and it takes me to the MAIN.PHP fine and displays my username fine, I then click the basket page and it also displays my username fine, but when I click from the BASKET.PHP to the MAIN.PHP it looses the username and displays nothing....

I have no idea what is going on and any help would be greatly appreciated, thanks.

Just modified your code at MAIN.php. Now it should work.

 session_start();

 session_save_path(trim(`echo ~`).'/php_sessions');    

if(!empty($_POST["username"])){
   $_SESSION['username']= $_POST["username"];
   $username = $_POST["username"]; 
}

if(!isset($_SESSION['username'])){
 header('location: index.php');
}

That is because you are assigning 

$_SESSION['username']= $_POST["username"];

on your main.php ,since there is no POST value there (as of now) , it gets overwritten.

Change your code on your main.php file like this

if(!isset($_SESSION['username']))
{
    if(isset($_POST["username"]))
    {
    $_SESSION['username']= $_POST["username"];
    $username = $_SESSION['username'];
    }
    else
    {
        header('Location:./index.php');
    }

}
