Not the first() or the last() but the second

In a template I have:

<?= $page->children()->first()->url() ?>

In another template I need to get the second sub element.

<?= $page->children()->second()->url() ?>

Doesn’t do it, because the keyword “second” doesn’t exist, I guess.

It is meant as a link from to a listing page.

Use nth() method like that:

<?= $page->children()->nth(1)->url() ?>

Note: the index starts at 0

Oh! Of course! Thank you very much!!

@Ndugu Please check if the page exists before calling the url() method:

<?php
if ($child = $page->children()->nth(2)) {
  echo $child->url();
}

Otherwise, you will run into an error if the page doesn’t exist.

So should I change the other one as well?

This

<?= $page->children()->first()->url() ?>

is for pagination, right? Or is it a shorthand? And why does it exist, when it could cause an error?

This gets the first child of all subpages of a page. But if the collection is empty (i.e. the page has no children), it will return an error.

It has nothing to do with pagination.
