Adding multiple products to the cart

[WJBroer]

I want to give the user the choice to order one product (a bottle of wine) or a box (six bottles). So I'm looking to have two buttons: one that adds one product and one that adds 6 products.

Any idea on how to do this?

This is my code. Right now both buttons add 1 product:

                                                <button class="btn btn-greensea btn-order" name="AddToCart_Submit" onclick="AddToCart({tag_catalogueid},{tag_productid},'',4,'','',false);return false;">

                                            <em class="icon-plus"> </em>  Bestel doos </button>

                                        </div>

                                        <div class="bestel">

                                            <button class="btn btn-greensea btn-orderfles" name="AddToCart_Submit" onclick="AddToCart({tag_catalogueid},{tag_productid},'',4,'','',false);return false;">

                                            <em class="icon-plus"> </em>  Bestel fles ({{totalprice | replace: ",", "." | currency}}) </button>

Thanks.

I got ordering six at a time to work this way:

<div class="bestel">

                                        <div class="hide">

                                        <select id="Units_{tag_productid}" class="productTextInput" name="AddToCart_Amount">

                                            <option selected="selected" value="6"></option> 

                                        </select>

                                        </div>

                                            <button class="btn btn-greensea btn-order" name="AddToCart_Submit" onclick="AddToCart({tag_catalogueid},{tag_productid},'',4,'','',false);return false;">

                                            <em class="icon-plus"> </em>  Bestel doos (6) </button>

                                        </div>

                                        <div class="bestel">

                                            <button class="btn btn-orderfles" name="AddToCart_Submit" onclick="AddToCart({tag_catalogueid},{tag_productid},'',4,'','',false);return false;">

                                            <em class="icon-plus"> </em>  Bestel fles ({{totalprice | replace: ",", "." | currency}}) </button>

                                        </div>

But now the second button also adds 6 products at once. Does anyone have an idea on how to get the second button to order only one product?
