Adding to $items in a Drupal view

I recently needed to add an extra link to the end of my $items list in a list view and found that this could be done quickly in template.php.

I set out to do two things:
- add a link to the end of my list view that does not contain node data
- as part of this last list item, include a custom link that changes depending on the name of the view

Accomplishing this was a lot easier than I expected. All I had to do was add a switch statement for the view name, and also add a line with the content I wanted to add to my $items array before the theming function.

Here is my code:

  1. <?php
  2. function phptemplate_views_view_list_myview($view, $nodes, $type) {
  3.   $fields = _views_get_fields();
  4.   $taken = array();
  5.  
  6.   // Set up the fields in nicely named chunks.
  7.   foreach ($view->field as $id => $field) {
  8.     $field_name = $field['field'];
  9.     if (isset($taken[$field_name])) {
  10.       $field_name = $field['queryname'];
  11.     }
  12.     $taken[$field_name] = true;
  13.     $field_names[$id] = $field_name;
  14.   }
  15.  
  16.   // Set up some variables that won't change.
  17.   $base_vars = array(
  18.     'view' => $view,
  19.     'view_type' => $type,
  20.   );
  21.  
  22.   foreach ($nodes as $i => $node) {
  23.     $vars = $base_vars;
  24.     $vars['node'] = $node;
  25.     $vars['fullNode'] = node_load($node->nid);
  26.     $vars['link'] = l($vars['fullNode']->body, 'node/' . $node->nid);
  27.     $vars['count'] = $i;
  28.     $vars['stripe'] = $i % 2 ? 'even' : 'odd';
  29.  
  30. //adding extra variable for view name contextual links, in a template, this will be $linked_page. 
  31. 	switch ($vars['view']->name) {
  32. 	case 'view_one':
  33. 		$vars['linked_page'] = '/news/special_one'; 
  34. 		break;
  35.  
  36. 	case 'view_two':
  37. 		$vars['linked_page'] = '/news/special_two'; 
  38. 		break;
  39.  
  40. 	case 'view_three':
  41. 		$vars['linked_page'] = '/news/special_three'; 
  42. 		break;	
  43.  
  44. 	case 'view_four':
  45. 		$vars['linked_page'] = '/news/special_four'; 
  46. 		break;
  47.  
  48. }
  49.     foreach ($view->field as $id => $field) {
  50.       $name = $field_names[$id];
  51.       $vars[$name] = views_theme_field('views_handle_field', $field['queryname'], $fields, $field, $node, $view);
  52.       if (isset($field['label'])) {
  53.         $vars[$name . '_label'] = $field['label'];
  54.       }
  55.     }
  56.     $items[] = _phptemplate_callback('views-happy_news', $vars);
  57.   }
  58. //the key, I'm adding a link to the $items[] array. 
  59. 	$items[] =  "<a href=\"{$vars['linked_page']}\" class=\"more-articles\">See more news</a> »";
  60.   if ($items) {
  61.     return theme('item_list', $items);
  62. }
  63. }
  64. ?>
