Seems to me you might be looking for something like this perhaps ?

>Is this possible?
in short: at the moment, no. there is no “combined menu” possibility/plugin – or whatever you might want to call it – in existence. (Not to my knowledge anyway)
One could probably – in theory – create some discount of some sort for this depending on what’s been put into the cart but I hazard a guess the idea is to be able to offer a “2 schnitzel with 2 beers” – i.e a combined menu – sort of thing with different taxrates depending on what’s part of that menu
this is currently not implemented (and no plans exist to do this in the sort or even medium term future from my side)

Sorry, only items that belong to the same (sub)category will be combined into the same (sub)category

no

not every order that gets started , gets completed so you will have what you call “empty orders”
even so, what’s the issue/problem ?

>…wasn’t sure it would do this kind of stuff…

no, it does not.
all it does is open the shop/site for ordering outside your regular opening times for an order to be fulfilled during your opening times (with some timeslots 5/10/15 etc minutes per hour during your openingtimes)
,though there are a couple of more settings that can be set to tweak some things a bit more

It does *not* do anything like “order “item A” now (lets say on the 10th Feb) for it to be *only* available on the 14th Feb for example

hope that clears things up…

since i cannot reproduce this here, it’s all kind of guess work , but we can try a couple of things regardless
as laid out below
( especially given that it seemingly works fine with COD orders so my current guess would be it’s a priorities issue somewhat…)

a) in wppizza-delivery-by-postcode.php you will find at approx line 60
add_action( 'plugins_loaded', 'wppizza_dbp_set_version', 11);
change this to
add_action( 'plugins_loaded', 'wppizza_dbp_set_version', 1000);

and save that file

b)in v3x.php at approx line 36 you will find
add_filter('wppizza_filter_formfields', array($this, 'wppizza_dbp_output_formfields'), 10, 2);
change this as well to read
add_filter('wppizza_filter_formfields', array($this, 'wppizza_dbp_output_formfields'), 1000, 2);
and save that file

try doing a paypal order and see if this now gets picked up in it and let me know

(i assume here you are comfortable with editing a few lines of php code , if not let me know)

“Cannot start session” errors MUST be fixed. a lot of things – and the issue described might well be one of them – will not work if this is the case

please see
https://docs.wp-pizza.com/troubleshooting/?section=headers-already-sent

hmm, so i cloned your site here as is , did a COD and a paypal order (using my own paypal credentials of course) and in both cases received the address information just fine.

the only thing I changed was
a) the paypal credentials (and there’s absolutely no reason i can think of that this could be the issue)
b) added the following to the wp-config.php before the /* happy blogging etc */ replacing your current WP_DEBUG etc cnstants

define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);/*this should NEVER be true for production sites*/
define('WP_MEMORY_LIMIT', '256M');

Admittedly I would be really surprised if adding those constants to your wp-config.php on your installation would suddenly fix the issue as they are somewhat addressing completely different things.

However, please try adding those to your wp-config.php (most certainly increasing your memory limit would be a good idea in any case) , do a paypal order (sandbox or live) when you get a chance and let me know.
I do NOT actually expect this to fix the issue you are having – I’d be quite surprised in fact if it did – but let’s make sure nevertheless

thanks

(if the above does not make sense to you / is too ‘techie’ , let me know and i’ll explain in more detail)
