Hey all. I know this isn’t a CartThrob community, but I was hoping to catch someone who may know about this.

In my CartThrob {update_cart_form}, I have a Matrix-populated zip code drop-down field. When a user clicks “Checkout” I want the value of the drop-down menu to pass as a variable to the checkout page and populate the billing zip code field. Is this possible?

I need this custom value as we only make deliveries to certain zip codes in our locale.

EDIT: You can actually view the precursor to this by going here: http://dandelionflowershop.com/index.php/website/cart

Keep in mind that you need $40 in your cart before delivery options become available.

You could try adding the save_customer_info tag inside the cart form tag (or inside the update_cart_form tag) to capture the zip code value, eg

{exp:cartthrob:save_customer_info_form return="cart/checkout"}
<label for="zip">Zip</label> 
<select id="zip" name="shipping_zip">
/* your matrix data*/
</select>
{/exp:cartthrob:save_customer_info_form}

When submitted carthrob will save the shipping_zip value and pass it to the checkout.

It’s worth adding CT’s debug tag to see what data the cart is holding, useful for debugging…

{exp:cartthrob:debug_info}
