Empty Cart in one click prestashop 1.6.1 - delete all products from cart

[dprovost1990]

Hello,

 

I need a one click delete all products in cart.  I found solutions for previous versions of prestashop, but not 1.6, and I even though I tried solutions for earlier versions I cannot get to work.  Please someone help me, as I need to just remove all products in cart with one button. I tried other solution that didn't work in prestashop 1.6. such as

And someone else needing same feature:

https://www.prestashop.com/forums/topic/388418-empty-cartdelete-all-products-from-cart-button-for-ps16-how/

 

EDIT:

I have solved this by piecing together different information, this is how I've accomplished to empty cart in one click with prestashop 1.6.1:

 

Add the link that calls emptyCart - add it somewhere in shopping-cart.tpl, as this is the cart page:
 

<a class="btn btn-default button button-medium exclusive" href="{$link->getPageLink('cart', true, NULL, "emptyCart=1&token={$token_cart}")}" title="{l s='Delete'}"><span>{l s='Clear Cart'}</span></a>

 

Inside CartController.php in root controllers directory, add the functions that empty out the cart:

 

protected function emptyCart()

{

 

$result = array();

$result['summary'] = $this->context->cart->getSummaryDetails(null, true);

foreach ($result['summary']['products'] as $key => &$product)

{

$this->processDeleteProduct($product['id_product'],$product['id_product_attribute'],$product['customization_id'],$product['id_address_delivery']);

} 

 

 

}

 

 

protected function processDeleteProduct($idProd, $idAttrib, $custom_id, $id_address)

{

if ($this->context->cart->deleteProduct($idProd, $idAttrib, $custom_id, $id_address))

{

if (!Cart::getNbProducts((int)($this->context->cart->id)))

{

$this->context->cart->setDeliveryOption(null);

$this->context->cart->gift = 0;

$this->context->cart->gift_message = '';

$this->context->cart->update();

}

}

$removed = CartRule::autoAddToCart();

if (count($removed) && (int)Tools::getValue('allow_refresh'))

$this->ajax_refresh = true;

} 

 

I added these functions right after init function, so line 65.

 

Inside same file, add the bit that actually runs the function when its called:

 

so, inside public function postProcess(), add elseif to the if statement:

 

so add:

 

elseif (Tools::getIsset('emptyCart'))

$this->emptyCart();

 

to:

 

if (Tools::getIsset('add') || Tools::getIsset('update'))

$this->processChangeProductInCart();

elseif (Tools::getIsset('delete'))

$this->processDeleteProductInCart();

elseif (Tools::getIsset('changeAddressDelivery'))

$this->processChangeProductAddressDelivery();

elseif (Tools::getIsset('allowSeperatedPackage'))

$this->processAllowSeperatedPackage();

elseif (Tools::getIsset('duplicate'))

$this->processDuplicateProduct();

 

mine looks like:

if (Tools::getIsset('add') || Tools::getIsset('update'))

$this->processChangeProductInCart();

elseif (Tools::getIsset('delete'))

$this->processDeleteProductInCart();

elseif (Tools::getIsset('emptyCart'))

$this->emptyCart();

elseif (Tools::getIsset('changeAddressDelivery'))

$this->processChangeProductAddressDelivery();

elseif (Tools::getIsset('allowSeperatedPackage'))

$this->processAllowSeperatedPackage();

elseif (Tools::getIsset('duplicate'))

$this->processDuplicateProduct();

awesome worked like a charm! although if I may add something for a little better security for you customers with a simple tweak 

 

<a onclick="return confirm('Are you sure you want to delete all items from your cart?');"class="btn btn-default button button-medium exclusive" href="{$link->getPageLink('cart', true, NULL, "emptyCart=1&token={$token_cart}")}" title="{l s='Delete'}"><span>{l s='Clear Cart'}</span></a>    

 

so they don;t accidentally delete anything

Hi, can you help me with AJAX cart?

 

Now, Ajax is the same. It is OK.

 

Problem was with cache-control on the hosting server.

Hi. This work for PS ver. 1.6.1.6

But i think all core modification should be in override folder. File for override folder (only if you dont have file with same name in override folder): https://drive.google.com/open?id=0B3xnLaE3af-Ybjg4bVFwZXdmLTg

 

Also, i found another one way, on this site: http://nemops.com/clear-cart-button-prestashop/#.WEWa7bKLQb9

Hi, 

 

 If you use customization, this should be changed:

 

$this->processDeleteProduct($product['id_product'],$product['id_product_attribute'],$product['customization_id],$product['id_address_delivery']);

 

to 

 

$this->processDeleteProduct($product['id_product'],$product['id_product_attribute'],$product['id_customization'],$product['id_address_delivery']);

 

 

Prestashop 1.6
