Override / append / prepend to Drupal 7 Node Page <title>

By Julian Pustkuchen, 26 May, 2021

In this previous blog entry you learned how to modify the node title itself. Here's how you can, for example for SEO purpose, modify the HTML page title of a node. You may for example add prefix or suffix text:

  1. function YOURMODULE_node_view($node, $view_mode, $langcode) {
  2.   if ($view_mode != 'full') {
  3.     // Do NOT override embedded nodes!
  4.     return;
  5.   }
  6.   $wrapper = entity_metadata_wrapper('node', $node);
  7.   switch ($node->type) {
  8.     case 'YOUR-NODE-TYPE-MACHIE-NAME':
  9.       _YOURMODULE_set_title($wrapper->fieldxyz->value() . ' STATIC TEXT ' . $node->title);
  10.       break;
  11.   }
  12. }
  13.  
  14. /**
  15. * Helper function to set the current page title.
  16. **/
  17. function _YOURMODULE_set_title($title) {
  18.   $maxLength = 120;
  19.   if(is_string($title) && count($title) > $maxLength){
  20.     substr($title, 0, strrpos(substr($title, 0, 120), ' '));
  21.     drupal_set_title(trim($title, " \n\r\t\v\0&amp;-,;:"));
  22.   }
  23. }

 

hook_node_view and  drupal_set_title do the trick for you :)
