help with array

nyl

I have this code:

$_SESSION['productid'][] = $productid;

it gives me this error:

Fatal error: [] operator not supported for strings in......

any suggestion ?

planetsim

$_SESSION['productid'] = array($productid);

nyl

it doesn't give me an error anymore, but it doesn't do what it is supposed to do anymore.

As you can see I'm passing a value using a multidimensional array. Unfortunately the proposed solution doesn't update the multidimensional array.

That's because $_SESSION['productid'] is not a multidimensional array, it's a string (like the error message says). You must be setting it to a string value somewhere else, and then the program's choking when it gets to here.

so make like this:

$_SESSION['productid'] = array();

and then:

$_SESSION['productid'][] = $productid;

IF you want to store multiple products

leatherback, it assigns the word 'Array' when i use the code you suggested.

this simple script is a shopping cart.

I keep adding new items to the cart using this code:

$_SESSION['productid'][] = $productid;
$_SESSION['prod_name'][] = $prod_name;

and then I list the item in the cart using this code:

 $_SESSION['array_len'] = count ($_SESSION['productid']);

for ($i = 0; $i < $_SESSION['array_len']; $i++) {
     echo"Prod. ID: " . $_SESSION['productid'][$i];
     echo"Prod. Name: " . $_SESSION['prod_name'][$i];
}

etc...

it works fine on my local machine.
it works fine on the server the first time i load the page containing this script (after that it gives the fatal string error).

any more suggestions ?
