Modular page: link to next sibling

Hello,

In a submodular page, I try to get a link to the next submodular.
Thanks to the documentation I could get to this code:

{% if page.isLast(page.path) == false %}
    <a href="#{{ page.prevSibling(page.path).title }}">next</a>
{% endif %}

This works... but I don't understand why.
I would have guessed that I had to use nextSibling, not prevSibling.
Could anyone explains this to me ?

Hi, I think this depends on the collection ordering. Can you paste the parent page header?

Sure:

---
content:
    items: '@self.modular'
    order:
        by: default
        dir: asc
        custom:
            - _texte
            - _texte2
---

nextSibling is not returning anything? Or it returns the same value as prevSibling?

It returns what I excpected would be nextSibling.

I have first _texte then _texte2
nextSibling returns _texte
prevSibling returns _texte2

Edit :
Well, maybe I can be more clear.

What I try to achieve is to have:

• a button next submodular for each submodular except the last one
• a button previous submodular for each submodular except the first one

I create the links like this (I've changed it a bit since first post):

{% if not page.isLast(page.path) %}
    <a href="#{{ page.prevSibling(page.path).title }}">next</a>
{% endif %}
{% if not page.isFirst(page.path) %}
    <a href="#{{ page.nextSibling(page.path).title }}">next</a>
{% endif %}

The link created in the first submodular of the list is the prevSibling, and the one in the last sumbodular is nextSibling

Thank you for the explanations !
I never thought it that way. I'll know that I should inverse next and prev.

May I suggest to precise it in the documentation ?
This way is perfectly clear :

Assuming you have the pages:
Project A
Project B
Project C
You are on Project A, the previous page is Project B.
If you are on Project B, the previous page is Project C and next is Project A

Oh one thing: you're using prev/nextSibling on the Page object. That is slightly different than the prev/nextSibling methods on the Collection object:

https://learn.getgrav.org/api/Grav/Common/Page/Collection.html#method_prevSibling

You don't need the parameter in your case.

Perfect, I didn't know !

Done. :)
