                $('#cart').html(response);

        });
    });

Answer 1

On the loop of return of your AJAX, put all the result in one concatenated string inside a variable. then echo that variable serve as return in ajax.

make sure that there is an tags with an ID "cart"

ajax.php

<?php
$return = "";
while($row = mysqli_fetch_assoc($products)):
$id = $row['id'];
$return .= "<div class='item-in-cart clearfix'>
    <div class='image'>
        <img src='images/$id' width='124' height='124' alt='cart item' />
    </div>
    <div class='desc'>
        <strong>
            <a href='product.html'>s</a>
        </strong>
        <span class='light-clr qty'>
            <a href='#' class='icon-remove-sign' title='Remove Item'></a>
        </span>
    </div>
    <div class='price'>
        <strong></strong>
    </div>
</div>";
endwhile;

echo $return;
?>

then the lump of HTML data will be push and insert inside the cart ID tags, but also upon calling the ajax, or before it get insert, empty the cart id first

$('#cart').html('');
$('#cart').html(response);
