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
$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
$this->cart->insert()
$this->cart->update()
and set the quantity to 0;
Example:
$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:
$items['qty'] = trim(preg_replace('/(^[0]+)/i', '', $items['qty']));
$items['price'] = trim(preg_replace('/(^[0]+)/i', '', $items['price']));
And instead of these line:
// let's unset this first, just to make sure our index contains only the data from this submission
unset($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] = $val;
}
// Woot!
return TRUE;
Change it to this :
// let's unset this first, just to make sure our index contains only the data from this submission
unset($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;
