problem in shopping cart.

[rahia307]

i developed session based shopping cart. using this code.

    $_SESSION['cart'][]= array( 'prd_name' => $prd_name, 'unit_price' => $unit_price,
    'qty' => $qty, 'id_prd' => $id_prd);

and i use this code to display values placed in session.

foreach($_SESSION['cart'] as $key=>$value){
echo $value['prd_name'];
echo $value['qty']; 
}

Now my question is that. How can i update values placed in a session. i other words how can i update my shopping cart

Bold, italic and underlined text is meant to place emphasis on parts of your text, not the entire question. Making the whole thing bold, underlined AND italic only makes it harder to read and as such is not allowed.

Please remember that when posting in the future!

Thank you.

To update a session variable, you simple re-set it's value, just like you did when you first created it.

The $_SESSION super-global works just like an array, and can be created, edited and unset just like any regular array.

You can see an example of this in this article.

Well when you

$_SESSION['cart'][]= array( 'prd_name' => $prd_name, 'unit_price' => $unit_price,
'qty' => $qty, 'id_prd' => $id_prd);
 

you add to the $_SESSION['cart'] array another value. And it is stored like this:

$_SESSION['cart'][0] = your first product added
$_SESSION['cart'][1] = your second product added
// and so on
 

so you might want to update your session like this ( knowing you $_SESSION['cart'] index. ) :

$_SESSION['cart'][0]['prd_name'] = 'another value';
