The old session was probably still populated with the string version.

This is the old version I demonstrated. You should go with the later
version that sets the values to the quantity :)

I thought I had? Haven't I?
But this is the easiest shopping cart I have ever seen.
However, I still have not understood what you were doing with these
lines I commented out.
if( isset( $_SESSION['TrolleyContents'][$_POST['RNum']] ) )
{
# $_SESSION['TrolleyContents'][$_POST['RNum']] -= 1;
# if( $_SESSION['TrolleyContents'][$_POST['RNum']] <= 0 )
# {
unset( $_SESSION['TrolleyContents'][$_POST['RNum']] );
# }
They did not work, or seem to?

I'm resending a better way to do the simple trolley since you seemed to
have created a Frankensteinian merge of the two examples I sent
previously. This version uses functions which should probably be put
into their own source file and included (let's call it lib.trolley.php).
<?php
session_name( 'CCLTrolley' );
session_start();
//
// Initialize the trolley.
//
if( !isset( $_SESSION['TrolleyContents'] ) )
{
$_SESSION['TrolleyContents'] = array();
}
function trolleyItemQuantity( $itemId )
{
$trolley = &$_SESSION['TrolleyContents'];
//
// Return the $quantity of $item in the $trolley.
//
if( isset( $trolley[$item] ) )
{
return $trolley[$item];
}
return 0;
}
function trolleyItemExists( $itemId, $quantity )
{
$trolley = &$_SESSION['TrolleyContents'];
//
// Return true if $item is in the $trolley; otherwise return false.
//
if( isset( $trolley[$item] ) )
{
return $trolley[$item];
}
return 0;
}
function trolleyItemAdd( $itemId, $quantity )
{
$trolley = &$_SESSION['TrolleyContents'];
//
// Add $quantity of $item to the $trolley.
//
if( isset( $trolley[$item] ) )
{
$trolley[$item] += $quantity;
}
else
{
$trolley[$item] = $quantity;
}
}
function trolleyItemRemove( $itemId, $quantity )
{
$trolley = &$_SESSION['TrolleyContents'];
//
// Remove $quantity of $item from the $trolley.
//
if( isset( $trolley[$item] ) )
{
$trolley[$item] -= $quantity;
if( $trolley[$item] < 1 )
{
unset( $trolley[$item] );
}
}
}
function trolleyPrint()
{
//
// Display the trolley.
//
echo "<pre>\n"
.implode( ',', array_keys( $_SESSION['TrolleyContents'] ) )
."\n</pre>\n";
}
?>
Now the following would facilitate the action you appear to be
performing in your example for adding to the trolley:
<?php
include_once( 'lib.trolley.php' );
if( isset( $_POST['ShopAction'] ) && isset( $_POST['RNum'] ) )
{
echo $_POST['ShopAction'].'!!<br />';
if( 'add' == $_POST['ShopAction'] )
{
echo 'Adding '.$_POST['RNum'].'...<br />';
trolleyItemAdd( $_POST['RNum'], 1 );
}
else
if( 'delete' == $_POST['ShopAction'] )
{
echo 'Deleting '.$_POST['RNum'].'...<br />';
trolleyItemRemove( $_POST['RNum'], 1 );
}
}
else
{
echo 'No action specified!!<br />';
}
trolleyPrint();
?>

Well, I guess you are right. One can compile multiple versions of PHP to
run as Apache module in parallel by changing the sources (one has to
change some symbol names) but I think Strato didn't do that since most
shared hosting services run PHP as CGI anway for security reasons.
Also, I think writing applications with high performance requirements
somewhat contradicts deploying them on shared hosts. If you need
performance: Get a dedicated server and - if you want - even compile yer
own hand-optimized PHP.
And: Clever development circumvents the CGI bottleneck. Developing is
absolutely no problem under CGI since it's done by just a few users and
here the flexibility of multiple version kicks in: You can freely
choose! For the production version you simply use a good userland cache
that minimizes the work done by PHP.

I see that you have received some answers already but I wanted to point out
something very obvious....learn how to plan a software application. I know
that I am old school, but I see far too many developers today winging it. A
lot of the reason is that many languages now lend themselves to being
self-taught, and while learning the language is great it is not the only
thing a programmer needs to know about developing software.
A basic flowchart could have helped you to answer your question and broken
down the processes into their componenet parts. Heck, you don't even need
fancy flowcharting software...just write down the steps.

Hi there,
I am having problems with users who upload text that only contains upper case
letters. For example "SEARCHING FOR". Is there a way to detect this via PHP?`
I would like to have the script return him to the form and inform him that this
is not allowed.
So basicly I need a sort of regex which does detect upper case letters in a row.
Has anybody ann idea how such an regex could look like?
Thank you for any hint,
Merlin

I'm looking for where apache / php will be saving the user session
files. when I do a phpinfo(), it tells me that session.save_path will
be temp but when I look at the files in there, there are only a
couple of files and they say nwIN;
Is there any way to directly access the session files in this way to
get at the values?

Is this the safest way to send GET variables ?
Guess I am trying to improve my code :)
//----------------------------------
// 'Sending' PHP script:
require_once("/home/includes/encryption.inc");
$str
=encrypt(urlencode("movie=mymovie.mov&mask=mask.gif&drag=drag.gif"));
$finalURLString = $pathtoReceivingScript.$str ;
//----------------------------------
// 'Receiving' PHP script:
require_once("/home/includes/encryption.inc");
$str =$_SERVER['QUERY_STRING'];
parse_str(urldecode(decrypt($str)),$getVarArray);
$movie = $getVarArray['movie'];
$mask = $getVarArray['mask'];
$drag = $getVarArray['drag'];
//echo "$movie,$mask,$drag";
//----------------------------------
// Encryption.inc
// Encrypt
function encrypt($encrypt) {
$key = "6r9qEJg6";
srand((double) microtime() * 1000000); //for sake of MCRYPT_RAND
$iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256,
MCRYPT_MODE_ECB), MCRYPT_RAND);
$passcrypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $encrypt,
MCRYPT_MODE_ECB, $iv);
$encode = base64_encode($passcrypt);
return $encode;
}
// Decrypt
function decrypt($decrypt) {
global $key;
$key = "6r9qEJg6";
$decoded = base64_decode($decrypt);
$iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256,
MCRYPT_MODE_ECB), MCRYPT_RAND);
$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $decoded,
MCRYPT_MODE_ECB, $iv);
return $decrypted;

$PHP_SELF should not be used because it will not work without
register_globals being enabled. Rather, you should use $_SERVER
['PHP_SELF'] for it as above however...
Don't forget to check for XSS! Using PHP_SELF you could simply change
the URL in the browser to:
/path/to/script.php"><script>alert('hello');</script><b "
so always run on htmlspecialchars on PHP_SELF!
<a href="<? echo htmlspecialchars($_SERVER['PHP_SELF']).'?
action=bigger';?>">
