Fetching sub-page fields dynamically or better method

The CMS Questions
5

Thank you again… and for clarifying getting current children. I think I can achieve what I want if I understand one more thing…

You said: Not sure I understand the question, but in your template, you get the page from the field like described in our docs: Files | Kirby CMS

But I’m not using files. I am using pages. In my POPUP blueprint I have:

fields:
      popnext:
        label: Next Item
        type: pages
        multiple: false

This gives me a field when I edit the POPUP - where I can see all pages, and select one. It then stores it in the text file like this:

----

Popnext: - page://ot5ezju9Jfy3ReYV

This is the UUID of the page - I think. But I don’t know how to then get this and use it.

In my template, I need to read the ‘popnext’ field for the current page - then find the page it refers to (how?), and get the fields from that page (like layout, subtitle, and popnext).

I hope this makes sense. I’m sorry, I come from HTML and wordpress - so I’m probably using all the wrong terminology…
