Array Question - Help Required

kbc1

I have managed to add items to a shopping cart session array using this method:

	    $_SESSION['basket'][$_POST['id']] = array('quantity' => $_POST['quantity'], 'productprice' => $_POST['productprice']);

This works great, however, I am now at the stage where I need to extract the results from the session array and display the data on screen - like you would see in your Basket View on a website.

I planned to run a query which selects the product data from the database where the product 'ID' is found within the Session Array, but i have no idea how to reference or explode this session array so I can access the data.

Can anyone explain or point me in the right dircetion of how i go about referencing the data within these session arrays (example below):

Array
(
    [5] => Array
        (
            [quantity] => 1
            [productprice] => 100.00
        )

[7] => Array
    (
        [quantity] => 1
        [productprice] => 300.00
    )

[6] => Array
    (
        [quantity] => 1
        [productprice] => 200.00
    )

[8] => Array
    (
        [quantity] => 1
        [productprice] => 400.00
    )

)

Thanks for any help you can offer as I am very new to using associative arrays.

Try something like this:

<?php
 session_start();
 foreach( $_SESSION['basket'] as $id => $array ){
  if( !is_array($array) ){
    exit(' I\'ve got no quantity/price data...');
  }
  list( $quantity, $price ) = $array;
  echo 'PRODUCT ID: ' . $id . '<br />
   Quantity: ' . $quantity . '<br />
   Price: ' . $price . '<hr />';
 }
?>

Hope this help

Hi Konrad

Thanks for the suggestion but unfortunately the $quantity and $price are not showing up (i.e. seem to be null), however the $id is displaying fine and when i do the following:

print_r($array);

I can see the price and quantity in the array as such:

Array ( [quantity] => 1 [productprice] => 100.00 )

Any suggestions on how to fix it?
Thanks in advance.

Note: list() only works on numerical arrays and assumes the numerical indices start at 0.

foreach ($basket as $id => $array) { 
    if (!is_array($array)) { 
        exit('No quantity/price data...'); 
    } 
    echo 'PRODUCT ID: ' . $id . '<br />' 
       . 'Quantity: ' . $array['quantity'] . '<br />' 
       . 'Price: ' . $array['productprice'] . '<hr />'; 
}
