Cant get image upload script to work

[sid0972]

here is the script i am using

 

 

<?php
session_start();
define ("MAX_SIZE","10000");

function getExtension($str) {
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
}


$errors=0;

if(isset($_POST['Submit']))
{
for($i=0; $i<count($_files['image']['name']);$i++)
{

$image=$_FILES['image']['name'];

if ($image)
{

$filename = stripslashes($_FILES['image']['name']);

$extension = getExtension($filename);
$extension = strtolower($extension);

if (($extension != "jpg") && ($extension != "jpeg") && ($extension != "png") && ($extension != "gif"))
{

echo '<h1>Unknown extension!</h1>';
$errors=1;
}
else
{

$size=filesize($_FILES['image']['tmp_name']);


if ($size > MAX_SIZE*1024)
{
echo '<h1>You have exceeded the size limit!</h1>';
$errors=1;
}

$directoryPath = "images/".$_SESSION['valid_user'];
if (is_dir($directoryPath))
{
echo "exists<br>";
$image_name=time().'.'.$extension;

$newname="/images/".$_SESSION['valid_user']."/".$image_name;
}
else
{
echo "not exists";
$directorypaths = "images/".$_SESSION['valid_user'];
mkdir($directorypaths, 0755);
$newname="/images/".$_SESSION['valid_user']."/".$image_name;
}

$copied = copy($_FILES['image']['tmp_name'], $newname);
if (!$copied)
{
echo '<h1>Copy uunsuccessfull!</h1>';
echo "<a href=\"member.php\">Click</a>";
$errors=1;
}}}}}


if(isset($_POST['Submit']) && !$errors)
{
echo "<h1>File Uploaded Successfully! Try again!</h1>";
echo "<a href=\"member.php\">Click</a>";
}

?>

<form name="newad" method="post" enctype="multipart/form-data" action="image_upload.php">
<table>
<tr><td><input type="file" name="image"></td></tr>
<tr><td><input name="Submit" type="submit" value="Upload image"></td></tr>
</table>
</form>

 

i copied this from somewhere and modified it a bit.

 

I want it to check if a directory of the name of current user is already in the /images folder, and if not, it should create a directory by the name of current user and save images in there.

So i added this part here

 

 

$directoryPath = "images/".$_SESSION['valid_user'];
if (is_dir($directoryPath))
{
echo "exists<br>";
$image_name=time().'.'.$extension;

$newname="/images/".$_SESSION['valid_user']."/".$image_name;
}
else
{
echo "not exists";
$directorypaths = "images/".$_SESSION['valid_user'];
mkdir($directorypaths, 0755);
$newname="/images/".$_SESSION['valid_user']."/".$image_name;
}

 

and i would take a guess that this part is not working.

Any help is appreciated.
