Insert row into a view

Question

I have a view which fetches nodes from content type A, arranges them in a grid and uses a displaysuite buildmode to render them...nothing fancy so far. Now I want to insert a specific node of content type B at a specific position in the grid...like this:

+----------+----------+
|          |          |
|  type A  |  type A  |
|          |          |
+----------+----------+
|          |          |
|  type B  |  type A  |
|          |          |
+----------+----------+
|  type A  |  type A  |
.          .          .

I'm not sure where to start. I was hoping there would be some hook, preprocess function or whatever where I get an array of node objects to insert my special node into which then gets rendered...

Answer 1

I found the function I was looking for. You can insert nodes in the results array just after the query has been executed.

This goes in the module:

function modulename_views_post_execute(&$view) {
  // wait for the right view
  if($view->name == "name_of_the_view") {
    // create the object you want to insert in the result
    $temp = new stdClass;
    // creation date of that node   
    $temp->node_created = 1314807643;
    // nodeID
    $temp->nid = 13;

    $new_result_array = array();
    $i = 0;
    foreach($view->result as $single_result) {
      if($i == 2) {
        // insert the extra node at 3rd position
        $new_result_array[] = $temp;
        $new_result_array[] = $single_result;
      } else {
        $new_result_array[] = $single_result;
      }
      $i++;
    }
    // replace the old result array
    $view->result = $new_result_array;
  }
}

Answer 2

For any latecomers to this question, there's a module that does just this Views Row Insert

It has it's limitations when you start to push it, but it would do just as OP requests with very minimal effort and no hooks needed.

Answer 3

You can do it also using views theming feature. Place PHP file views-view-unformatted--taxonomy-term--page.tpl.php right in your theme's folder and with this code you can print custom code after every 3th row for Taxonomy term page default views:

<?php if (!empty($title)): ?>
  <h3><?php print $title; ?></h3>
<?php endif; ?>
<?php foreach ($rows as $id => $row): ?>
  <div<?php if ($classes_array[$id]) { print ' class="' . $classes_array[$id] .'"';  } ?>>
    <?php print $row; ?>
  </div>
  <?php if ($id == 2): ?>**My custom code after first row in Drupal views**<?php endif; ?>
<?php endforeach; ?>

This line does the trick

<?php if ($id == 2): ?>**My custom code after first row in Drupal views**<?php endif; ?>
