remove from basket

[phpanon]

Hi,

 

My remove from basket is working exactly right. At the moment when [-] is clicked it removes the item from the basket even if the quantity is more than one.

 

Ideally I would like to just decrease the quantity by one.

 

<?php
session_start();
foreach($_SESSION['basket'] as $key => $product) {
	if ($_SESSION['basket'][$key]['URN'] == $_GET['URN'])
	{
		unset($_SESSION['basket'][$key]);
	}
}
header("Location: StationaryMain.php?var=URN");
exit();
?>

I presume $_SESSION['basket'][$key]['URN'] holds the quantity, if so something like the following should do it:

<?php
session_start();

foreach($_SESSION['basket'] as $key => $product)
{
    if ($_SESSION['basket'][$key]['URN'] == $_GET['URN'])
    {
        // decrease quantity by one
        $_SESSION['basket'][$key]['URN']--;

        // unset quantity if new quantity is less than 1
        if($_SESSION['basket'][$key]['URN'] < 1)
        {
            unset($_SESSION['basket'][$key]);
        }
    }
}

header("Location: StationaryMain.php?var=URN");
exit();

?>

Hi,

 

I tried your suggestion... it doesn't seem to be working. It wont remove anything now?!

 

Here it the code that calls that page too

 

<a href="removefrombasket.php?URN=<?php echo $product['URN']?>">[-]</a>

What does $_SESSION['basket'][$key]['URN'] and $product['URN'] hold?

how do i check? lol

[wildteen88]

Umm, you should now that, its your code... isn't? To find out:

echo '<pre>' . print_r($_SESSION['basket'], true) . '</pre><br /><br />' . $product['URN']; ?>

ooh sorry, i miss understood your question!!??

 

URN is the ID of the product. Sorry

[wildteen88]

I understand now what URN is, its the product identifier. I have modified my code.

<?php
session_start();

foreach($_SESSION['basket'] as $key => $product)
{
    if ($_SESSION['basket'][$key]['URN'] == $_GET['URN'])
    {
        // decrease quantity by one
        $_SESSION['basket'][$key]['quantity']--;

        // unset quantity if new quantity is less than 1
        if($_SESSION['basket'][$key]['quantity'] < 1)
        {
            unset($_SESSION['basket'][$key]);
        }
    }
}

header("Location: StationaryMain.php?var=URN");
exit();

?>

Yeah I realised what you meant by the question afterwards.

 

Sorry about that

 

 

Thank you for your time
