Question

Is it possible to create “Remove from cart” Url for a product with a custom function, so that i can place that function in my custom block which allows user to remove an item from cart…

Answer 1

If you examine, app/code/core/Mage/Checkout/Block/Cart/Item/Renderer.php and find the method: getDeleteUrl() will offer some insight on how its generated:

/**
 * Get item delete url
 *
 * @return string
 */
public function getDeleteUrl()
{
    return $this->getUrl(
        'checkout/cart/delete',
        array(
            'id'=>$this->getItem()->getId(),
            Mage_Core_Controller_Front_Action::PARAM_NAME_URL_ENCODED => $this->helper('core/url')->getEncodedUrl()
        )
    );
}

You can find the call to this in template/checkout/cart/item/default.phtml:

<td class="a-center"><a href="<?php echo $this->getDeleteUrl()?>" title="<?php echo $this->__('Remove item')?>" class="btn-remove btn-remove2"><?php echo $this->__('Remove item')?></a></td>

With this info you should be able to create a new controller action for the cart to simply remove a specific ID to a product in the cart’s index.

Hope this helps.
