Delete one item of the cart passing ID to a php page

Hi,

I need to delete on item of the cart. I tryed the "remove Link" option but it does not work.

My idea is to pass the ID od the element of the cart to a php page that roam the cart and when the id equald detele the item.
I tryed with the DeleteFormCart() method that i have seem in the object but it does not work.

Any sugestions?

Thanks!

You would have to loop through the cart to find the item you wanted to delete and then delete it... this function would do the trick:

function DeleteByID($cart,$id) {
    for ($n=0; $n<sizeof($cart->Items); $n++)      {
      if ($cart->Items[$n])     {
        if ($cart->Items[$n]->ID == $id)     {
          $cart->Items[$index] = null;
          $cart->ReIndexContent();
          $cart->ResetAll();
          $cart->SaveCart();
        }
      }
    }
}

Thanks Ray!!

It is posible to do the same to update one item passing the id?

Thanks for the support. Congratulations on some extensions like "Framework builder" who now have become indispensable for us and have no alternative in the market. I hope we will soon have news about you :)

Yes. For example to update a quantity you could use something like:

function UpdateQuantityByID($cart,$id,$qty) {

    for ($n=0; $n<sizeof($cart->Items); $n++)      {

      if ($cart->Items[$n])     {

        if ($cart->Items[$n]->ID == $id)     {

          $cart->Items[$n]->Quantity = $qty;

          $cart->SaveCart();

        }

      }

    }

}

Hi Ray,
I have been trying to implement this feature but for some reason is not working for me. Nothing is being deleted.
This is what I'm doing.
1) From the view-cart.php I have a "Remove" link next to each item loaded in the cart. This link looks like:
<a href="remove.php?cart=<?php echo session_id(); ?>&id=<?php echo $eCart1->DisplayInfo("ID"); ?>">Remove</a>

2) Then, the link points to a remove.php page that grabs the info and tries to execute the delete function you provided to Oscar. The page looks like this:

<?php
$cart = $_GET['cart'];
$id = $_GET['id'];

function DeleteByID($cart,$id) {
for ($n=0; $n<sizeof($cart->Items); $n++) {
if ($cart->Items[$n]) {
if ($cart->Items[$n]->ID == $id) {
$cart->Items[$index] = null;
$cart->ReIndexContent();
$cart->ResetAll();
$cart->SaveCart();
}
}
}
}
?>

For some unknown reason, nothing happens. No error messages either. Any clue by looking at the above code?
I'm adding the required pages in the remove.php as wel:
<?php require_once("../WA_eCart/eCart1_PHP.php"); ?>
<?php $eCart1->GetContent(); ?>

Thanks much for your time!

It doesn't look like you are calling the function... don't you need to add:

<?php

$cart = $_GET['cart'];

$id = $_GET['id'];



function DeleteByID($cart,$id) {

  for ($n=0; $n<sizeof($cart->Items); $n++) {

    if ($cart->Items[$n]) {

      if ($cart->Items[$n]->ID == $id) {

        $cart->Items[$index] = null;

        $cart->ReIndexContent();

        $cart->ResetAll();

        $cart->SaveCart();

      }

    }

  }

}



DeleteByID($cart,$id)

?>

I did forget that part, thanks.
But still not working. I have sent the view-cart and remove pages to see if you can see where I'm failing. Is it maybe the id I'm passing? I'm using <?php echo $eCart1->DisplayInfo("ID"); ?> instead of <?php echo $eCart1->DisplayInfo("WAUID"); ?>.

Any clue will much appreciate it.

You shouldn't be passing the cart in through the url. The cart is an object and can't be passed that way.

I think it should just be:
$eCart1

like:

<?php

$id = $_GET['id'];



function DeleteByID($cart,$id) {

  for ($n=0; $n<sizeof($cart->Items); $n++) {

    if ($cart->Items[$n]) {

      if ($cart->Items[$n]->ID == $id) {

        $cart->Items[$index] = null;

        $cart->ReIndexContent();

        $cart->ResetAll();

        $cart->SaveCart();

      }

    }

  }

}



DeleteByID($eCart1,$id)

?>

Yes, just tried that. Not working either sadly.

Is it maybe the id I'm using for the item?
I'm using this one: <?php echo $eCart1->DisplayInfo("ID"); ?>
Should I use this one instead: <?php echo $eCart1->DisplayInfo("WAUID"); ?>

ID is correct.

You had:
if ($cart->Items[$n]->ID == $id) {
$cart->Items[$index] = null;

$index doesn't exist... it should be:
if ($cart->Items[$n]->ID == $id) {
$cart->Items[$n] = null;
