Logic to find image

jimbobrjames · February 18, 2018, 12:25pm

Throughout my site I have a number of pages that act as sections. These include top level pages. Basically, if a page has children, it is considered a section page, no matter what depth it is in the site. These section pages all have a field on it to set a section image. I want to display this image on this section page, and all pages that are children of this page.

Whats the most efficient way to climb up from from current page, look for the section image field, and display it? At the top level, you cant climb up because there is nowhere to go. I don’t know wether its better to look up or down the tree.

<?php

// return content from the last parent
page::$methods['parentField'] = function($page, $field) {
  if($page->parents()->count()) {
    return $page->parents()->last()->{$field}();
  } else {
    return $page->{$field}();
  }
};
