Delete specific row in the Cart - El Forum - 11-30-2011

[eluser]Unknown[/eluser]
I try to delete a specific row in the cart using the cart library.
which I noticed that it has no delete function. Some forums suggest that
you can use update function

Code:
$this->cart->update()

and set the quantity or
price perhaps to 0. But!, still for me it doesn't work.

I explored the library and made few changes.
I used

Code:
$this->cart->insert()

instead of

Code:
$this->cart->update()

and set the quantity to 0;

Example:

Code:
$data = array(

   'id'   => $id,

   'qty'     => '0',

   'price'   => '0',  

   'name'    => 'DELETED'

   );

   $this->cart->insert($data);

these are the lines that need to be change in the library.

Remove or comment the line:

Code:
$items['qty'] = trim(preg_replace('/(^[0]+)/i', '', $items['qty']));

Code:
$items['price'] = trim(preg_replace('/(^[0]+)/i', '', $items['price']));

And instead of these line:

Code:
// let's unset this first, just to make sure our index contains only the   data from this submission

unset($this->_cart_contents[$rowid]);  

// Create a new index with our new row ID

$this->_cart_contents[$rowid]['rowid'] = $rowid;

// And add the new items to the cart array   

foreach ($items as $key => $val)

{

     $this->_cart_contents[$rowid][$key] = $val;

}

// Woot!

return TRUE;

Change it to this :

Code:
// let's unset this first, just to make sure our index contains only the data from this submission

  unset($this->_cart_contents[$rowid]);  

  // Create a new index with our new row ID

  if($items['qty'] == 0) 

  {

   unset($this->_cart_contents[$rowid]['rowid']);

  }

  else

  {

   // And add the new items to the cart array 

   $this->_cart_contents[$rowid]['rowid'] = $rowid;

   foreach ($items as $key => $val)

   {

    $this->_cart_contents[$rowid][$key] = $val;

   }

  }

  return TRUE;
