HTML

    <a href="javascript:void(0);" onclick="cart.add('<?php echo $product['product_id']; ?>');"> <i class="fa fa-shopping-cart"></i><!--<img src="images/cart-icon.png" alt="cart" />--></a>
                                                            <div>Add To Container</div>
                                                            <form id="formSend" method="post" >
                                                            <input type="hidden" value="<?php echo $product['product_id']; ?>" name="sendProductId"  class="pID" />
                                                            </form>
                                                        </li>

JS

$( ".sendRequest" ).each(function(index) {
                $(this).on("click", function(){
                    var otherInput = $(this).find('.pID').val();
                    $.ajax({
                        type:"post",
                        url:"index.php?route=common/personaliseyourflowers",
                        data:otherInput,
                        success:function(response){
                            alert(response);
                        }
                    });
                });
            });

Php Code

if(isset($this->request->get['sendProductId'])){
        $cookie_value = $this->request->get['sendProductId'];
        setcookie($cookie_name, $cookie_value, time() + (86400 * 30));

        }

        print_r($_COOKIE);

Also when i print the global variable of cookie it also giving blank array.

Answer 1

replace

data:otherInput,

with

data:{'sendProductId':otherInput},

Answer 2

correct your Ajax call as below.

   $.ajax({
                    type:"post",
                    url:"index.php?route=common/personaliseyourflowers",
                    data:{'sendProductId':otherInput},
                    success:function(response){
                        alert(response);
                    }
                });
