Wow, nice.
Thanks, that helps a lot! 😀

I have now taken the time to come to the following conclusion.

Wpizza does not work properly in a commercial design that is based on Elementor and delivered with WooCoomerce.

How did I come to this conclusion?

Because I have now tried 4 different commercial themes and all four have the same problem (for information, from different providers). When the order is sent, the thank you page no longer loads in the same template/layout but in the standard template on the same page (I found this out by examining the pages).

I paid for two of the themes myself and borrowed two others. All themes were in the standard installation with the demo content (which you could not specifically deselect in 3 themes, but needed to have the layouts for the individual Elementor pages) with WPpizza then the standard pizza category with the order page widget and the set shopping cart page. Only the email sending was deactivated in the tools.

And the same for all of them. I then spoke to Elementor Support, they referred to WPPizza, as did WooCoomerce Support, and at least the supporters of the two themes I bought also pointed to WPPizza as the cause.

So now I’m faced with a problem and nobody can or wants to help me. I don’t have the skills to understand why Wppizza is the only one that’s making things difficult at this point. I do NOT want to set up the whole thing with WooCoomerce, which is why I extended the licenses for WPPizza and the plugins in the set. I also spent money on one or two themes that should be appropriately appealing.

Unfortunately, the CSS code didn’t help much either, as only the thank you page output is formatted a little on the layout-less page. I know you don’t want to put your energy into it, but it must be possible somehow for the thank you page output to be in the same template as the shopping cart. WooCoomerce has the option to define a shopping cart and a checkout page in the settings. Unfortunately, adjustments to this to use possible filters or hooks for WPPizza didn’t help.

So I’m asking you again if you have any ideas on how I can continue to use WPPizza in the themes I’ve bought. Is there perhaps a way to implement this in the functions.php?

I love WPPizza and have been working with it for years. It worked wonderfully well in my old theme, but the provider removed it from the portfolio years ago and because of all the PHP updates, I can only use it rudimentarily and only in an outdated PHP version. If I can’t control this one problem, I’ll have to switch to WooCommerce and that’s really not what I’m looking for. 🙁

I think I have a logical error.

The following situation:
There is a pizza, let’s say it’s called Della Casa. And it has various ingredients. But now the customer doesn’t want an ingredient on this pizza. So how can I set it up so that the customer can remove one or even several ingredients, such as olives, from the pizza and/or add other ingredients such as broccoli.

So that the shopping cart then says:
Della Casa
(German prefix “Ohne” for no)
Ohne ham, Ohne olives, 1x broccoli, 1x etc…

With the preselection, the customer could remove unwanted ingredients, and the prefix would appear in the shopping cart. However, the remaining ingredients and those that the customer adds would also be visible in the shopping cart.

So what would be the logical order to implement this in the settings for the products whose ingredients can be removed?

Hehe, don’t worry, like I said, take your time.
I fixxed this now and set up a single page for it, it’s not the best solution but it’s okay.
Actually, I try to find out, why the “+” of this shortcode won’t slide in and show the pieces of information when the order was done. As far as I remember this was the case but somehow now it does not work. :/

Okay after a few tests I found the following out.

When you register on the page (during the ordering process) everything works fine.
When you try a second order after you logged in and you come to the last checkout page, the content it doubled.
And when you do a third order, then the checkout pages triples the content and so on.

Wow…I dunno how to fix this. xD

I will test it out in a few days and will report you how it worked. 🙂
