why does my session end?

Posted on 16th Feb 2014 by admin

my connect.php starts the session just so you know
i can navigate arround my site fine except when i come to this page. it lets me in but then when i try to leave no matter what page i go to or which page i come from it shows the error !is_authed

Also can someone check my code i wasnt sure if i could do a loop within another one
Code: <?php
include_once 'Connect.php';
if (!is_authed())
{
die ('You are not permitted to view this page, <a href="index.php">click here</a> to go back.');
}
?>
<html><head><title>Untitled Document</title>
<link href="style.css" rel="stylesheet" type="text/css"></head>
<body>
<div class=logo><?php include "logo.php";?></div>
<div class=navigationbarbox><?php include "navigationbar.php";?></div>
<div class=welcome>
<?php
// Checks friends
$member = $_SESSION["id"];
$query = ("SELECT * FROM friends WHERE member = '$member'");
$result= mysql_query ($query) or die ('Could not query.');
$exist = mysql_num_rows($result);
if($exist=='0')
{
echo"You have no friends";
}
else // if any friends gets
{
while ($row = mysql_fetch_assoc($result))
{
$friendwithid = $row["friendwith"];

$query = ("SELECT * FROM members WHERE $friendwith = '$friendwithid'");
$result= mysql_query ($query) or die ('Could not query.');
while ($row = mysql_fetch_assoc($result))
{
$photo = $row["photo"];
$username = $row["username"];
}

echo "<img src='http://www.myurl.co.uk/NEWTEACH/userimages/$photo' width='100' height='150'>
";
echo"$username
";
echo'<a href="friendsdelete.php?userid='.$userid.'">Remove Friend</a>';
}
}
