>Because I am beginner with your plugin I am having these problems…

as you have not given me any link to your site, i would suggest reading this first:
https://support.wp-pizza.com/topic/things-to-do-on-first-install/

in the future: for new questions please start a new topic
https://support.wp-pizza.com/topic/forum-rules-read-me-before-posting/

regarding your first question please see the user examples that have screenshots explaining the way they are set up here
https://support.wp-pizza.com/twentytwelve/our-menu/user/
please note: although it is possible to make some sort of “meal deals”, it is not really the purpose of the add ingredients plugin (as i said, it’s doable though as in the examples above with a bit of creativity)

regarding your second question: wppizza->layout :”Enable increase/decrease of items in cart via input field/textbox”
may i also suggest you familiarize yourself with the options on offer in the various plugin screens/pages

should be fixed in 4.13.3.3
(one of these difficult to find, easy to fix things)

that said, having a play around with it here , i can (sometimes) reproduce this.
will need to find out under what circumstances and will fix things if needed

thanks for reporting

the args list doesn’t really do much there. its the following filter that does the sorting

add_filter('terms_clauses', array($this,'wppizza_term_filter'), '', 1);

i just told you

in the future, please post a new topic

anyway, you should look in the wppizza->layout settings for the minicart. possibly an added offset for the body might do the trick.

>I know it will be passed on to stripe but what if the delivery zip code is different than the billing zip code,
the you would have to label that filed “billing zip code” i would have though

> I thought that there is an option to have another field in stripe popup window for the billing zip code.

if there is, that would be great/better. got an example somewhere that does that ?

Out of the box, no.
However , I would be happy to add this as an option if you could run a test for me by editing
wppizza-gateway-stripe.php like so and tell me if this works (i would then have to make this a more dynamic option in the plugin itself, but as a test this should be fine).

wppizza-gateway-stripe.php on approx line 393 AFTER

$js[]="if (stripeEmail == null){var stripeEmailVal='';}else{var stripeEmailVal=stripeEmail.value;}";

ADD

	$input_field_id = 'ccustom6'; /* set the id of the field enabled and set for entering Post/Zip codes in wppizza->order form settings */
	$js[]="var stripeZip = document.getElementById('".$input_field_id ."');";
	$js[]="if (stripeZip == null){var stripeZipVal='';}else{var stripeZipVal=stripeZip.value;}";

setting the $input_field_id (the field you are using in wppizza->order form settings for the customer to enter his/her zipcode). Make sure you set this field in the settings there as being required

then, wppizza-gateway-stripe.php on approx line 407 AFTER

$js[]="name: '".$name."',";

ADD

$js[]="address_zip: ''+stripeZipVal+'',";

for this to have any effect, enable declines on verification failures in your stripe account settings.

let me know

something like this probably/perhaps
