I've been learning cart throb for about a month off and on and there's one functionality that seems to be missing. If I'm trying to purchase three black shirts I will use a quantity tag:
{exp:cartthrob:multi_add_to_cart_form class='forms product-forms id{purchasable_products:entry_id} off' entry_id="{purchasable_products:entry_id}" no_tax="{no_tax}"}
<input type="hidden" name="entry_id[{count}]" value="{entry_id}" />
{exp:cartthrob:item_options entry_id="{purchasable_products:entry_id}"}
{select class='width-70 margin-bottom' limit="1"}
<option {selected} value="{option_value}">{option_value} {if option_price_numeric != 0} ({option_price}){/if}</option>
{/select}
{/exp:cartthrob:item_options}
<input type="text" class="product_quantity" name="quantity[{count}]" value="1">
</label>
<p>
<button type="submit" class="btn btn-green add-to-cart" data-target="cart-update">Add to Cart</button>
<a href="/shopping/view-cart" class="btn btn-blue btn-disabled view-cart-button"><i class="icon icon-shopping-cart"></i>View Cart</a>
<a href="/shopping/checkout" class="btn btn-green btn-disabled checkout-button">Checkout</a>
</p>
{/exp:cartthrob:multi_add_to_cart_form}
When I add those three items, they show in my cart as three separate entries rather than one entry with one quantity.
Which says items are added, but the cart total is $0.00 and still shows as multiple entires in the view cart page. View cart code is
{exp:cartthrob:cart_items_info}
{product_photos limit='1'}
<img src="{product_photos:photo}" alt="{product_photos:photo_title}">
{/product_photos}
<h3 class="pull-left">{title}</h3>
Which results in looped out items, but adds no money to the cart. My goal is to only show a single item, with its proper quantity and proper cart price.
