Page depth below specific parent

The CMS Questions

I’m building out a kind of microsite that I want to be able to be plugged in anywhere at any page depth and still work. I’ve got some very important help from @texnixe (as seen here Passing field value/variable to child pages - #7 by texnixe), which is awesome.

The new challenge is figuring out how to get page depth but base it on a specific parent page, so that I can have depth-based settings that work no matter what depth the whole sub-structure is located at. This could possibly build off of the previous thread, which tells me which page I have set as my top-level page for this microsite.

What would be really cool is if I could pass a parent page to $page->depth() and get the depth below that parent. But that doesn’t seem to currently be a thing.

I can get a count of parent pages with $page->parents()->count(), but I need a way to stop that at the specific page I’m looking for so I can get depth below that. Any ideas?

$page->parents() gives you an array of all the parents. You can get the key of a specific page using indexOf():

$page->parents()->indexOf('somepage');

An index of 0 would be the immediate parent of the page etc. You should be able to work it from there, taking the number of elements in the array into account?

Excellent. Using that in combination with the page method you provided from the other thread gives me exactly what I need.
