as you noticed, the prices fields only accept prices.

however, as of v2.11.8.6 (should be available in a couple of days or so) you will be able to add this to your themes functions.php

add_filter('wppizza_filter_output_format_price','my_function');
function my_function($priceformatted){
/*get rid of any formatting first and cast to  integer*/
$price=(int)str_replace(array(',','.'),'',$priceformatted);
/*if zero, display some text instead*/
if($price==0){
$priceformatted='some text';/*set this to whatever text you need to be displayed*/
}
return $priceformatted;	
}

note: this is only advisable like this if you do not offer any actual ordering – as you said you don’t – and it applies to *all* menu items with a price of zero – though you could set the one it applies to to an impossibly high price (let’s say 99999.00) and do if($price==9999900){ etc . otherwise you’ll have to jump through some more hoops

hope that helps

already there….

sounds more like a coding error your end to be honest.
i am using that exact same code here and it works just fine

you need to find out what your internal error is

if you get an internal server error you CLEARLY got some error somewhere.
enable debug , it might help you
(my guess is you have a rogue space somewhere or a closing bracket too many/ too few)

> Could it possibly interact poorly with the Theme itself

no, it’s a straight forward filter to be put in the functions.php file (or your child functions php file if you created a child theme – which is always preferable)

of course, make sure that your child theme works first before messing around with anything in there

>Nothing different
not likely 🙂

>THANK YOU FOR ALL OF YOUR HELP!!
you’re welcome, glad you got it working

there’s a filter you could use wppizza_filter_summary which holds all order data in cart (and a bunch of other stuff)

you could probably filter on [items][price] . very roughly something like

if ([items][price] <= 0) {
[items][price_formatted] = 'my string'  
} 

you need to adjust the above with proper coding for filters of course, but it should give you an idea

Note, you can screw up a lot of things if you use this incorrectly. make sure you test it thoroughly

PS: This kind of thing/filter ill be a lot easier in wppizza v3.x when it’s ready. However, this will be a while yet and the above will have to do for now

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.
