Question

I have for each loop which when looping outputs the items held in a basket array. This works great, but I want to store a few things per EACH item in session variables so I can use this information elsewhere, I am trying to create session variables inside the foreach loop, but of course the variables need to have different names every time it loops through a different item. I have researched how to create variables dynamically, I couldn’t figure it out. This is something I have always felt would come in handy, but as it seems difficult I just avoid it, but now I want to know if its possible.

Here is my for each loop code, you can see inside the three session variables I want to create for each item in the basket:

foreach ($basketarray as $value)
{
    echo "<div id='basketitems'><br/>                                       
    ".$value['name']."<br/>
    ".$value['id']."<br/>
     &pound;".$value['price']."<br/>
     ".$value['size']."<br/>
    Quantity: ".$value['quantity']."<br/><br/>
    <img id='searchimage' src=".$value['picture']." width='210' height='250' /><br/>";

    $_SESSION['Bprodid'] = $value['id'];
    $_SESSION['Bprodquantity'] = $value['quantity'];
    $_SESSION['Bprodprice'] = $value['price'];

echo "<form action='deletefrombasket.php' name='basketdelete$items' id='basketdelete$items' method='POST'>

    <input type='submit' name='".$value['basketid']."' value='Remove' id='basketid' name='basketid'/>

    </form></div>";

$items++;
}
?>
    <div id='basketdetails'>
<?php

echo "<p>items ". number_format($basketitems)."</p>";
echo "<p>Total &pound; ".number_format($baskettotal, 2, '.', ',')."</p>";


if($basketitems && $baskettotal !=0)
{
    echo "<a  href='clear.php'>Empty Basket</a>";
    echo "<a  href='checkout.php'>Checkout</a>";
}

So it is possible to do something like this? I was trying to create varaible names by using a counter but I was unsuccessful.

I would appreciate any advice.

Thanks

Answer 1

Your session variable can be a multi-dimensional array, so before the loop you can say:

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

And in the loop:

$_SESSION['my_values'][$value['id']]['Bprodquantity'] = $value['quantity'];
$_SESSION['my_values'][$value['id']]['price'] = $value['price'];
// etc.

Edit: To loop through all your values you can use:

foreach ($_SESSION['my_values'] as $key => $values)
{
  echo $key; // the ID of your product
  echo $values['quantity']; // the quantity
  echo $values['price']; // the price
}
