Get "like children" render nav

[louisstephens]

I have been scratching my head on this one for an hour. How do you get the parent (of the current child page) and list all the children for a navigation.?

[diogo]

Well, if you want to do literally that

$page->parent->children

but this is better 

$page->siblings

or, to exclude the current page

$page->siblings("id!=$page")

or

$page->siblings->remove($page)

[louisstephens]

Ah ha. That was easy enough 

I did  notice that it displays the Id, how would you display the actual Page Name/url?

[diogo]

See this example and adapt it to the markup that you want https://github.com/ryancramerdesign/ProcessWire/blob/master/site-beginner/templates/_head.php#L51-L53

Thanks diogo. I do appreciate the help. Still feeling my way around Processwire (came from Wordpress) and I still am trying to tackle things with that mindset.

The beginner profile template files (like the one I linked to) have very well commented examples of these kind of things, have a good look at them.

You'll get the hang of it in no time, you'll see

Yeah, I am slowly getting there. I did notice after doing some more research into the basic install that: "// top navigation consists of homepage and its visible children".

However, what I was trying to snag were the children of a child. 

For example:

Home

  - Fish

      - Bass

      - Brim

      - Carp

  - Site Map

  - About

In the above example, I was trying to pull the children of  "Fish". Perhaps I set this up wrong as I couldnt figure out a way to get "Fish" to be top level like Home.

[diogo]

In that case, you just have to get the fish page and then get it's children $pages->get("/fish/")->children

Or, if you're planning to use that page again later in the code:

$fish = $pages->get("/fish/");

$fishChildren = $fish->children;

foreach ($fishChildren as $item) {
    ...
}

I thought I had it with:

<?php if($page->rootParent->hasChildren) {
			echo $page->children;
} ?>           

But I guess I am missing something important here.

[diogo]

$page->children is an array, you can't echo it directly:

foreach($page->children as $child) {
    echo $child->title;
}

[louisstephens]

Thanks Diogo.

I got it with:

<?php
     foreach($page->siblings as $child) {
          echo "<a href='{$child->url}'>{$child->title}</a>";
     }
?>
