the wordpress inbuilt thickbox library/js (which the popup uses) is not responsive (unfortunately) and is currently set to width=580, height=520 which should fit onto pretty much any “normal” computer screen

of course, many mobile devices are smaller,
so, you could probably write some javascript that dynamically resizes things and also adds an overflow:auto on an element or some such

along these lines i guess
http://stackoverflow.com/questions/6699344/change-thickbox-popup-size-dynamically

alternatively, hitting the “print” button might work as it opens a completely new window (depends on device how exactly this will pan out though)

none.

but as for the main wppizza plugin as well as all gateways/extensions etc the following is the case:

frontend:
the frontend can always be used in any language regardless of whether a translation exists for a particular plugin or not.
If a translation exists it will only be used ONCE – on install – to fill the localization strings with defaults.
If a translation does not exists, it will be filled with english defaults.

After these defaults have been added, you can translate/change the localization strings to whatever you like so you can also of course translated them to any other not-included language language

administration/backend:
if it has been translated, it will follow whatever language has been chosen in WP. If it has not been translated yet, english will be used .
Note: as most plugins are work in progress, it may be the case that a translation exists for a given language, but not all strings have been translated, so you might get a mixture of your chosen language and english.

hopefully the above explains how this works

i don’t know what you are doing , but perhaps
https://support.wp-pizza.com/topic/adding-customer-checkout-fields/ ?

other than that, if you add a field from the “order form settings” page , it will be available everywhere

…So, effectively, you are building the plugin to be as universal as possible…
sure, that’s got to be the goal

..hence there’s no need for registration?..
not entirely sure what you mean by that.

..who’s making a prank order…
i cannot see how anything – short of having prepayment by credit card – will guard against that anyway

…they can simply order by phone and skip the hassle of entering their personal data on the site…
sure, if they want. chances are this will take a lot longer for your employees to do than just getting the final order sent to them

..you seem to be building this software, thinking like a customer, but you are actually selling it to the businesses..
absolutely. you have no business i can sell to if you do not have any customers

..it may turn out there are more crazy sellers like me, who have the same seemingly strange requirements..
this might well be true. at the moment – from what i can see or the request i receive – it isn’t the case

if it doesn’t suit me, it’s not your problem
also true. as much as i try, there is no way it can be everything for all people and scenarios or circumstances

>wouldn’t you say that images are as universal as text, when it comes to the Internet?
sure, but you still have to send them somehow. they don’t send themselves

require email, which takes anywhere from a second to a few days for someone to receive on his mobile device
only if not setup correctly (server and/or client side) and messaging services are not 100% foolproof/reliable either

all mobile devices either have Viber or Whatsapp
ok, i cannot proof that this is not the case where you are, but i doubt very much that *all* mobile devices have this guaranteed installed, and even if they do, that everybody uses it and is registered with those services

I can’t force you into developing your program in a direction you don’t care about
it’s not that i don’t care about these things. i just think it’s impractical (as it stands anyway)
that said, am happy to learn and having this conversation is interesting.
I just haven’t been convinced yet that this is something of intrinsic value to add

report back with the code, if I am successful.
please do.

for the moment – even ignoring the details – this statement

> – It’s universal –

is just wrong

email is universal, messengers aren’t.

even if we assume everybody has some sort of messenger software – which they don’t – you – as the receiver – has to have *absolutely all* messenger softwares available installed so as to not miss / being able to accept an order (not just a few).
furthermore, some messanger softwares only work on PC, some on Mac some on Android , iOS etc etc
so you’ll need all of those too

in any event, I am not stopping you to do such a thing, and if you do I would also of course be interested to see it .

I can guarantee you though, at least in the foreseeable future, this will not be part of the plugin/added as an option in the core somewhere.

>and any changes I make to wp-pizza will be gone with each update.
that’s why you should use actions / filters. that’s what they are there for

i would have thought using the filter provided in the print template

wppizza_filter_print_order_items

will give you the ability to sort in whatever sorting order you want to do

faqs:
https://support.wp-pizza.com/topic/sorting-menu-items/

feel free to use the filter included there to do that if you want.
after all, that’s the reason for filters are there and being included in various places.

in any event – and for the moment or foreseeable future – I don’t think it will be included in the plugin as default or an option . sorry.
(though never say never of course)
