from xampp local webserver to other server

[thijscream]

hey ppl,
you helped me out allot of times, so i come back to you once again, i just transfered my website from a local pc(for testing) to a webserver @ my hosting.
now some parts arent working correctly.
some extra info about the page:
What kind of web page is it: Webshop
what was the server is tested it on: windows xp machine with xampp installed
what is the server where i get the errors: realy have no idea.

well here is my first problem:
when i add an item to my shopping cart everything goes fine and it looks like this:
http://img269.imageshack.us/img269/1344/afb1s.png
then i press on the shopping cart icon and i get the following error:
http://img824.imageshack.us/img824/3683/afb2.png
also when i add extra products it's not stored.

this all works well on the local machine but not there.
as you can see i get the following error:
Er staat 1 product in uw winkelwagen.

SELECT naam, prijs6, prijs12, prijs24 FROM wijnen WHERE id = ArrayUnknown column 'Array' in 'where clause'
in file /home/rb005851/public_html/cart.php on line 71
Productnaam Hoeveelheid Prijs p/s Totaal

translated for english ppl in here:
there is 1 product in your shopping cart.

SELECT name, price6, price12, price24 FROM wines WHERE id = ArrayUnknown column 'Array' in 'where clause'
in file /home/rb005851/public_html/cart.php on line 71
productname amouth price/piece total

here is the source code, hopefuly you can help me out here :)

For some reason $product[0] contains an array, instead of a single value. Since you also state that more products are not handled correctly, I think the adding to the $cart is causing this problem.

I am not sure why you are using a pipe (|) as separator in it. You can just use $_SESSION['cart'] as any other array.

sorry for the late delay, but how would you try to fix this?
still kinda new to this and i realy don't get why my xampp server supports everything but the hosting server does not... :S

[thijscream]

btw i would like to add some extra info:

i added this:

echo '<pre>Inhoud $_SESSION[\'cart\']';
print_r($_SESSION['cart']);

when i try it on http://localhost/wijnkado/cart.php
i get the following:
with 1 product in cart:
Inhoud $_SESSION['cart']13,12
with 2 products in cart:
Inhoud $_SESSION['cart']13,12|57,12

and when i do this on http://kerstenswijnhandel.nl/cart.php
with 1 product in cart:
Inhoud $_SESSION['cart']13,12
with 2 products in cart or after refresh:
Inhoud $_SESSION['cart']Array,|12,12

does anyone know how to fix this?

[pritaeas]

Show the code where you add to $_SESSION['cart']

never mind, i found after 1 day searching what was the problem,
i changed the variable $cart to $cartz and that solved the problem.
