>Important is the handling for the Order user
i agree

it’s also a somewhat unique setup you are trying to achieve and just a way to make it work regardless.
it would be easier of course if one were to be able to just exclude a custom group from a size altogether or some such thing, instead of adding additional exclusion groups. alas , this is not implemented at the moment though might be one day

typically you do not have the same ingredients/topping (whatever you want to call it) multiple times for an item. furthermore they MUST have different id’s (reason for copying it)

>Its not the smartest way to handle my problem,
as i said, the easiest would be to have 3 different menu items. after all the plugin cannot possibly cater for every single unique way people want to do things. That said, it’s clearly still possible – as outlined

it’s doable albeit not quite as straight forward as – presumably – you want to offer the same flavours for all three
reading your scenario, there is perhaps a way to an an option for this in the plugin at some point to make this simpler. alas , at the moment you would have to do wither of the following

option a): much simpler, but not really what you are asking for (but thought i’d mention it anyway).
– create 3 distinct menu items “3 balls”, “5 balls” , “7 balls”
– create all your flavours as ingredients
– create 3 custom groups, each having all the flavours but setting min/max requirements distinctly for each (which is why you need 3) and assign them to the menu items created above

option b) – i.e keeping one menu item with 3 sizes (3,5,7)
– create all your flavours as ingredients
– copy all these flavours 2x. So you end up with 3 times the same bunch of flavours (as every ingredient in a menu item must have it’s own id)
– create 3 custom groups, each having all the flavours but setting min/max requirements distinctly for each (which is why you need 3) and assign them to the 3,5,7 menu item above
– create 3 more custom groups,using “exlude” option to exclude as required (if all items from a group hve been excluded, the whole group will not show up anymore)

reading this through, i actually created this here with screenshots (as it might be be helpful)

there is no easy way to do this other than jumping through A LOT of hoops (you would have to write your own plugin filtering carts etc – see codesnippets)
alternatively – you could be setting up 2 sites (in a multisite setup perhaps) and using one for delivery and one for pickup

i really do not understand why you would want to send this attachment to everybody that might be set up as recipient and not just to one dedicated email that can actually do something with it

i.e on order execute hook create your file as you described above and then just send it along these lines

		/*email parameters - tweak as appropriate */
		$headers   = array();
		$headers[] = "MIME-Version: 1.0";
		$headers[] = "From: Sender Name <[email protected]>";/**who its from->edit as required**/
		$headers[] = "X-Mailer: PHP/".phpversion();
/* you might need some more headers like content type etc to do attachments properly */
		
		$to = '[email protected]';/** edit as required **/
		
		$subject = 'my attachment';/** edit as required **/
		
		$message = 'my message';/** edit as required **/
		
		$attachments   = array();
		$attachments[] = "[absolute/path/to/attachment]"; /** edit as required **/		
		

		/*send the email*/
		$send_attachments =wp_mail($to, $subject, $message, $attachments);

not tested , but this sort of thing anyway

you should also check – if using some mail/smtp plugins that the authentication – if used- matches things (just stumbled across the below)

“…..address to a different value than what you authenticate with may help mark your Email as Spam. Namely Gmail, Hotmail and Yahoo Mail……”

sounds pretty much like your issue

the screenshots you sent are exactly the ones i needed. thanks.

however , if all other emails work then there is a server issue
it might well be that your server is blocked by gmail/hotmail/yahoo
you should speak to your host about that (perhaps missing PTR/MX/DMARC entries)

furthermore (probably the first thing to test / do ) try using SMTP, this might help
see your own http://sd-1257395-h00005.ferozo.net/wp-content/uploads/2017/01/1.png

(and of course enable it)

also , i would suggest you enable debug – might tell you something (https://support.wp-pizza.com/topic/how-to-enable-debug-in-wordpress/)

pics look ok
is your shop email address something like [email protected] ?
(i.e do you get a big red DMARC notice at the top of your admin screen or not )

in any event, with your settings, if it’s sent to the shop, it’s sent to the customer (it’s simply a cc)
if it does not go there, your mailserver has an issue (perhaps not the proper MX/PTR/DMARC etc etc entries)
essentially, this has nothing to do with the plugin, but the mail server setup somewhere

speak to your host. they should investigate those emails
as i said, with your settings the customer gets THE SAME email in cc so if it does not get there they(your email host) should investigate

have you looked at the “simple meal for 2” here ?
https://support.wp-pizza.com/twentytwelve/our-menu/user/
“2 minimum selections required, 2 maximum selections allowed”

re videos:
that isn’t really practical with the 1000’s of options one could possibly come up with (and 1000’s more the plugin wasn’t even designed for but I have seen being used for those – like special offers etc )

you should most certainly – first of all – fix the “sending QUERY packet” error
http://stackoverflow.com/questions/30753674/error-while-sending-query-packet

although i do not think this is caused by wppizza actually, if anything makes your db connection fall over it will of course impact everything (just setting the max packet size to something higher than default will probably do the job there)

regarding the actual issue, i cannot really test/see anything as you seem to have changed validation and/or codes

nor have you told me if disabling other plugins/theme fixes the issue or not , so i cannot say anything else really
