you have to pass it with form in $_POST array

then in cart controller you can use Tools::getValue('name') where 'name' is an name of variable from $_POST array.

btw. prestashop 1.6 doesnt use cart.php anymore.

I have implemented another way in by following code it will works fine initially it will change data in cart -summry but when i refresh page it will get back to orignal value , I thing there is any method of saving changes to cart that I missed..?

 

 

$.ajax({

type: 'POST',

headers: { "cache-control": "no-cache" },

url: baseUri + '?rand=' + new Date().getTime(),

async: true,

cache: false,

dataType: 'json',

data: 'controller=cart'

+ '&ajax=true'

+ '&update=1'

// + '&getproductprice=true'

+ '&summary=true'

+ '&id_product={$product.id_product}'

+ '&whole_cart='+partial_payment

+ '&token='+static_token

+ '&allow_refresh=1',

success: function(jsonData)

{

alert("success");

if (jsonData.hasError)

{

var errors = '';

for(var error in jsonData.errors)

//IE6 bug fix

if(error !== 'indexOf')

errors += $('<div />').html(jsonData.errors[error]).text() + "\n";

alert(errors);

$('input[name=quantity_' + id + ']').val($('input[name=quantity_' + id + '_hidden]').val());

}

else

{

if (jsonData.refresh)

location.reload();

updateCartSummary(jsonData.summary);

if (window.ajaxCart !== undefined)

ajaxCart.updateCart(jsonData);

updateHookShoppingCart(jsonData.HOOK_SHOPPING_CART);

updateHookShoppingCartExtra(jsonData.HOOK_SHOPPING_CART_EXTRA);

 

 

if (typeof(getCarrierListAndUpdate) !== 'undefined')

getCarrierListAndUpdate();

if (typeof(updatePaymentMethodsDisplay) !== 'undefined')

updatePaymentMethodsDisplay();

}

},

error: function(XMLHttpRequest, textStatus, errorThrown) {

if (textStatus !== 'abort')

alert("TECHNICAL ERROR: unable to save update quantity \n\nDetails:\nError thrown: " + XMLHttpRequest + "\n" + 'Text status: ' + textStatus);

}

});

it will post data fine as well as get response well it will display change value aslo, but after refresh it will roll-back
