Redirect anderer Seite in der Navigation

https://processwire.com/talk/topic/762-howto-menu-item-that-links-to-another-page/

1. Create a new field and call it 'redirect_url' or something like that, and use the 'URL' fieldtype.

2. Add that field to your template where you'd want to use it, or create a new template just for the purpose, like a template named 'redirect'.

3. Edit the page that you want to be a symlink and populate the 'redirect_url' field with the URL you want it to redirect to.

4. In your nav-generation code that links to the pages, do something like this:

<?php
$url = $subpage->get("redirect_url|url"); // use redirect_url if there, otherwise use url
echo "<a href='$url'>{$subpage->title}</a>";

5. You might also want to add this to your template that has the 'redirect_url' field: just in case there's anything linking to it directly. That way it'll send people to the right place either way:

<?php
if($page->redirect_url) $session->redirect($page->redirect_url); 

Breadcrumb

	<!-- breadcrumbs -->
	<div class='breadcrumbs'><?php 
		// breadcrumbs are the current page's parents
		foreach($page->parents() as $item) {
			echo "<span><a href='$item->url'>$item->title</a></span> "; 
		}
		// optionally output the current page as the last item
		echo "<span>$page->title</span> "; 
	?></div>

Navigation Bar

Nur 1.Level

	<ul class='topnav'><?php 
		// top navigation consists of homepage and its visible children
		foreach($homepage->and($homepage->children) as $item) {
			if($item->id == $page->rootParent->id) {
				echo "<li class='current'>";
			} else {
				echo "<li>";
			}
			echo "<a href='$item->url'>$item->title</a></li>";
		}
		// output an "Edit" link if this page happens to be editable by the current user
		if($page->editable()) echo "<li class='edit'><a href='$page->editUrl'>Edit</a></li>";
	?></ul>

Searchbar

	<!-- search form-->
	<form class='search' action='<?php echo $pages->get('template=search')->url; ?>' method='get'>
		<input type='text' name='q' placeholder='Search' value='<?php echo $sanitizer->entities($input->whitelist('q')); ?>' />
		<button type='submit' name='submit'>Search</button>
	</form>
