Is the active Page part of a specific 'Page' reference field?

[BenG]

Hi,

I'm building a second menu. Therefore I followed Ryans proposal from here: https://processwire.com/talk/topic/726-multiple-menus/#entry6018

I have 2 Page reference fields with PageListSelectMultiple as Inputfields and added both fields to the home template. Everything is working fine so far.

But: I want to check if the current (active) page is part of a specific Page field.

How can I do that?

Page fields:

• nav_main
• nav_side

Listing all pages from nav_side is simple:

foreach($pages->get("/")->nav_side as $item) {
    echo "<li><a href='{$item->url}'>{$item->title}</a></li>";
}

But how can I do something like that:

if (isset($page->nav_side)) {
    ...
}

Thank you!

Ben

I think this will work

$nav_sides = $pages->get('/')->nav_side;

if ($nav_sides->has($page)) {
    //...
}

Ah! Thank you. That does the trick!
