this is some of the code
mempic.php
<?php session_start(); ?>
{other code}
<?php
if (isset($_GET['id']))
{
$id = $_GET['id'];
$_SESSION['id'] = $id;
}
else
{
$id = $_SESSION['id'];
}
if (isset($_GET['clan']))
{
$clan = $_GET['clan'];
$_SESSION['clan'] = $clan;
}
else
{
$clan = $_SESSION['clan'];
}
$username='****;
$password='****';
$hostname='****';
$databasename='****';
$mysql_link = mysql_connect($hostname, $username, $password);
mysql_select_db($databasename);
$numresults=mysql_query("SELECT picture FROM ".$clan." WHERE id=".$id."");
$numrows=mysql_num_rows($numresults);
while ($row = mysql_fetch_array($numresults)) {
if ($row{'picture'}==""){
echo "<img width=\"150\" src=\"images/nopic.gif\"><br>";}
else {
echo "<p align=\"left\" class=\"header\">Current Picture: <p align=\"left\"
class=\"header\">";
$pathold=$row{'picture'}
?>
<img width="150" src="../<?php echo $row{'picture'};?>"><p align="left"
class="header">
<?php }}
echo $error;
?>
<p align="left" class="header">
<form action="connectpic.php" method="post" enctype="multipart/form-data">
<input type="hidden" name="pathold" value="<?php echo $pathold; ?>">
<input type="hidden" name="id" value="<?php echo $id; ?>">

</form>
connectpic.php
{other code}
<?php
if ($_FILES["picture"]["name"] == "")
{
if (!($pathold==""))
{
$del="/usr/local/psa/home/vhosts/clan3cho.co.uk/httpdocs/".$pathold;
unlink($del);
}
$update = "UPDATE ".$clan." SET picture='' WHERE id=".$id."";
mysql_query($update,$mysql_link) or die ($clan);
$mysql_insert = mysql_query($update, $mysql_link) or die(failed);
include 'memsub.php';
session_destroy();
}
else
{
if
(file_exists("/usr/local/psa/home/vhosts/clan3cho.co.uk/httpdocs/photos/".$_
FILES['picture']['name']))
{
$error= "<font face=\"Arial\" color=\"Yellow\"><strong>File with name
(".$_FILES['picture']['name'] .") already exists</strong></font><br>";
include 'mempic.php';
}
else
{
copy($_FILES['picture']['tmp_name'],
"/usr/local/psa/home/vhosts/clan3cho.co.uk/httpdocs/photos/".$_FILES['pictur
e']['name']) or die(failed);
$path="photos/".$_FILES['picture']['name']; ?>
<input type="hidden" name="path" value="<?php echo $path ;?>">
<?php
if (!($pathold==""))
{
$del="/usr/local/psa/home/vhosts/clan3cho.co.uk/httpdocs/".$pathold;
unlink($del);
}
$update = "UPDATE ".$clan." SET picture='$path' WHERE id=".$id."";
mysql_query($update,$mysql_link) or die ($clan);
$mysql_insert = mysql_query($update, $mysql_link) or die(failed);
include("memsub.php");
session_destroy();
}
}?>
when the file exists it goes back to mempic.php.. but keeps saying an error
due to session is already started.
Any Ideas how to get round this?
Thanks
