variables inside $SESSION[''] not reconized

NeedaCart

Could someone please help me. Take this example.
$TEST = "10"
$SESSION['$TEST ']

I then try to call the variable like so: $SESSION['10']

but php dosent seem to reconize it as a variable i.e 10 when its inside the session variable, just as $TEST.

Could someone tell me how to uses variables inside session vars, i know you lot are a lot smarter than me! THANKS!!

It's $SESSION not $SESSION and you assign $TEST to $SESSION like this

$TEST =10;
$_SESSION['TEST'] = $TEST;

Thanks for your help but that doesnt really solve my problems. I am basically creatinga virtual shopping basket and need to create variables on the fly using the productID. The way you did it means i am actually defining a variable when i dont know what it will be or how many i need! Does that make sense? e.g.

$productID = "20"

$_SESSION['$productID'] so it should be saved as

$_SESSION['20']

I cant do it any other way because all my pages are dynamic so the only way i can passs the productid is through variables

But it wont save as $SESSION['20'] just as $SESSION['$productID']

HOw do i do it?

i think you are slightly confused, why do you want to reference the session variable by its value?

If you want to store product id's and you dont know how many you could use an array?

I wanted it to save like that so all the session variables were different. How would i use an array?

I bascially need all the variables to be unique, possible with the productID in there somwhere.

Could someone show me a VERY BASIC example og how a shopping cart works, THANKS!!

$_SESSION[$productID]

If you want to use a variable, don't insist on turning it into a string.

OR to use the array idea and

$_SESSION['productID'][] = $productID;

to add a product ID to the array stored in $_SESSION['productID'].

Better yet; base it on what you would do in real life - a system that has been refined over thousands of years of commerce.

$_SESSION['cart']

would be an array of products in the cart. $_SESSION['cart'][0], $SESSION['cart'][1], $SESSION['cart'][2], and so on. Each product is representd by an array, with ['productID'] storing the product ID, ['quantity'] storing the quantity, and so on for whatever else needs to be stored.

Then $SESSION['cart'][4]['productID'] would be the product ID of the 4th item in the cart; $SESSION['cart'][4]['quantity'] would count how many of that item are stored, and so on.
