Unfortunately I need to link from other pages (infos.php) to “gegenseiten”. But I can’t figure out how to wright the php.

<?= $info->url() ?>

Gives me an error of “Undefined variable: info”.

I guess, because the content of “gegenseiten” is filled by different snippets the url has to be generated diffently tha with “->url()”.

Also I would like to somehow link to the listing page “infos” which content also gets generated by these snippets.

Must I use a route and go down the routes route?

Only the ancestor gegenseite? In that case you could use

<?= $page->parents()->last()->url() ?>

From where? From a child page? From anywhere?

You can always link to a page with the page helper and the full path:

<?php if ($infoPage = page('uber/infos')) { echo $infoPage->url(); } ?>

Or you can link to a parent page, e.g. if you are on an infos subpage and want to link to the listing (which is the parent):

<?= $page->parent()->url() ?>

This

<?= $page->parents()->last()->url() ?>

works fine for me.

But I need to also link from the snippets for “gegenseite” to the lists of all infos, news and gotchas.
So I tried

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

which of course gives me the last. Then I tried without “last”, but then it doesn’t know which one and gives me nothing, not even an error.

So I tried:

<?php if ($infoPage = page('uber/infos')) { echo $infoPage->url(); } ?>

but this gives me of course only that 1 page. So I tried something like this:

<?php if ($infoPage = page('uber/infos')) { echo $infoPage->url(); } ?>
<?php elseif ($infoPage = page('freenow/infos')) { echo $infoPage->url(); } ?>
<?php elseif ($infoPage = page('clevershuttle/infos')) { echo $infoPage->url(); } ?>
  <?php endif ?>

hoping I would do my first if/else thing right, but no.

Also just using “else” resulted in errors of the unexpected kind (end of file).

How, I mean what is the right way to do this.

Almost there!

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

seems to be the right choise!

Except for the title.

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

doesn’t give me the title.

87

But this does:

<?= $page->title()->html() ?>

and this:

<?= $page->title() ?>

stupid me. Sorry.

88

This works because a page always have a title.

This only works if children (subpages) for the current page exist. This isn’t always true and depends on your site’s structure.
