Make Node Fields Accessible in Page.tpl.php

- We have a vocabulary for site section, which can be used to apply a single term to each node.
- We want to label each node's site section in the branding area of page.tpl.php.
- The template page.tpl.php contains information about the nodes within, but they are buried deep with the $variables['page'] array.
- In our example, the field_site_section array is stored in the Title object of each node.
- We are only concerned with nodes displayed as pages.
Solution
- We update MYTHEME_preprocess_page() to check is we're displaying node.
- If so, set a new $variables item $variables['page_site_title'] using a function _MYTHEME_get_site_section().
- _MYTHEME_get_site_section() simply filters through all the noise in the $variable['page'] to find the site section tid, looks up the string value of for the term, and returns it.
In template.php (or equivalent)
/** * Implements hook_preprocess_page(). */ function MYTHEME_preprocess_page(&$variables) { // Makes the site section term easier to access in page.tpl.php if (arg(0) == 'node') { $variables['page_site_section'] = _MYTHEME_get_site_section($variables); } } /** * This function returns the string value of the site section from the Page scope, * so it can be easily accessed in page.tpl.php. * @param $variables * */ function _MYTHEME_get_site_section(&$variables) { $oTitle = $variables['page']['content']['system_main']['nodes'][arg(1)]['title']['#object']; if (property_exists($oTitle, 'field_site_section')) { $tid = $oTitle->field_site_section[LANGUAGE_NONE][0]['tid']; // Get the name associated with this tid. $term = taxonomy_term_load($tid); $page_site_section = $term->name; } else { $page_site_section = ""; } // We're returning here in an effort encourage devs to alter the // the $variables variable in MYTHEME_preprocess_page(); return $page_site_section; }
