jQuery AJAX Post not posting data

Right I have given in, after about 2 hours trying to figure out this issue I've caved, help me out stackoverflow!

Trying to post a product id along with quantity to a php file that will return errors if it finds any

jQuery code - 

$('span.add_to_cart').click(function () {
        $('div.cart').append('<span class="loading">LOADING</span>');
        $.ajax({
            type: "POST",
            url: "/onlineshop/scripts/add_to_cart.php",
            dataType: "json",
            data: { prod_id: $('input.product_id').val(), 
                    quantity: $('input.quantity').val()
            },
            contentType: "application/json",
            success: function(data) {
                $('span.loading').remove();
            },
            error: function(xhr, textStatus, thrownError, data) {
                alert("Error: " + thrownError);
                $('span.loading').remove();
            }
        })
    });

And my PHP page is just trying to print_r($_POST)

It seems that it is not posting my data, I've tried many many different things, all give me the error saying that there is no data being posted.

Try changing the contentType to application/x-www-form-urlencoded or just dropping it since it is the default value.

Your problem is that the data you are posting is not matching the content-type you are sending.

contentType is for the data being sent to the server, and dataType is for the data being received from the server.

Just remove the contentType: "application/json" from your code.
