$page->nextVisible() loop if page has checkbox selected

[Jonaspottie]

I have 10 subpages on a page.
8 of the 10 subpages have a checkbox selected in the cms.

I only want those 8 subpages to be in my next/previous flow.

I need something like: <?php if($next = $page->nextVisible() && $page->checkbox() == '1') ): ?>

Can someone help me?
Thanks!

Check the solution in this thread: Navigate into a collection with hasNext/hasPrev

Thanks for the fast response.
I’m very new at Kirby, so i need to make a new file under : plugins/collection.php and past it there?
And where do i need to check if the page contains a checked checkbox?

Thanks for the help!

You pass a filtered collection to the method, your collection would be:

$collection = $page->siblings(false)->filterBy('checkbox_field', '1');

The methods would go into /site/plugins/collection.php, in fact, it does not matter what you call the file, I usually call it methods.php.

I don’t think my function $page->getPrev is called correctly? i don’t get a return

I’ll try to look into this later, but please do post code as code snippets, not images. We don’t really want to type everything in to test it. Thank you!
