Shopping Cart

[jay_bo]

I have created a shopping cart and the products that have been added to the cart get displayed in the shopping cart page using this code, which works fine.

 

foreach($_SESSION['product'] as $prod)

{

if ($prod["qty"]!=0)

{

echo 'Quantity: '.$prod["qty"].' - '.$prod["title"].' - £'.($prod["qty"]*$prod["price"]).'<br/>';

}

}

 

and i add the products for the products page by

 

if ($_GET["add"]=="true")//This line gets the value and reads it

{

$_SESSION["cost"]=($_SESSION["cost"]+$_POST["price"]*$_POST["quanity"]);

$_SESSION["products"]=$_SESSION["products"]+$_POST["quanity"];

$_SESSION["order"]=$_SESSION["order"].$_POST["id"].",";

$_SESSION["product"][$_POST["id"]]["qty"]=$_SESSION["product"][$_POST["id"]]["qty"]+$_POST["quanity"];

header ('Location: products.php?cat=1');

}

 

How would i be able to delete a product from my shopping cart page?

 

Many thanks

when you add you are setting a group of session variables.

 

To delete, you unset($_SESSION['whatever'];

I tried that but it didnt seem to work....i used unset($prod["qty"]);  would that be correct in my case?

No you'll need to unset the actual $_SESSION variable. $prod will not be the same as $_SESSION. Where in your code are you trying to delete the product from your basket?

I'm trying to delete it from the checkout...so the user adds the products to the mini cart then clicks to go to checkout.

i'm sorry i just got what you actually ment.....

 

im displaying the products with this code and a link to remove each one.....

foreach($_SESSION['product'] as $prod)

{

if ($prod["qty"]!=0)

{

echo 'Quantity: '.$prod["qty"].' - '.$prod["title"].' - £'.($prod["qty"]*$prod["price"]).'<a href="shopping-cart.php?delete=true">Remove</a>'.'<br/>';

}

}

 

Then my remove code is....

if ($_GET["delete"]=="true")//This line gets the value and reads it

{

unset($prod["qty"]);

header ('Location: products.php?cat=1');

}

You will want to send the product id in the link too so you delete the correct $_SESSION variable. I'd change this

foreach($_SESSION['product'] as $prod)
      {
         if ($prod["qty"]!=0)
         {
            echo 'Quantity: '.$prod["qty"].' - '.$prod["title"].' - £'.($prod["qty"]*$prod["price"]).'<a href="shopping-cart.php?delete=true">Remove</a>'.'<br/>';
         }
      }

to

foreach($_SESSION['product'] as $prod_id => $prod)
      {
         if ($prod["qty"]!=0)
         {
            echo 'Quantity: '.$prod["qty"].' - '.$prod["title"].' - £'.($prod["qty"]*$prod["price"]).'<a href="shopping-cart.php?id='.$prod_id.'&delete=true">Remove</a>'.'<br/>';
         }
      }

 

Now when deleting the product use

if (isset($_GET['id'], $_GET["delete"]) && is_numeric($_GET['id']) && $_GET['delete'] =="true")//This line gets the value and reads it
{
   $prod_id = (int) $_GET['id'];
   unset($_SESSION["product"][$prod_id]);
   header ('Location: products.php?cat=1');
}

Thanks that seemed to do the trick, but it isnt removing it from the overal price.

Would be able to carry the price across aswel just like the id?
