I have built a module that adds a new custom content type. I need to use my own html.tpl.php for that content type, and the html template sits on my module folder.

I have done somee xperiments, I was able to replace the template of the node content, but it's not enough, and I can't seem to find some examples or explanatory documentation about it.

If my module is called "tomato" and my custom type is called "sauce", and I already have a file called html--sauce.tpl.php on my module folder, how do I tell Drupal to use that template when a "sauce" node is loaded?

  • It's not a duplicate, the other one is for a theme, I need it for a module, I tried the theme road, it does not work on module.

    I guess it wasn't obvious from the other question that hook_preprocess_html() can be used in module's. Answer added.

Modules can use hook_preprocess_html() to override theme templates. You need 3 things:

Using a module called MYMODULE, with a new node type mynodetype, & a template in the module dir named templates/html--mynodetype.tpl.php, we can add the following hooks to MYMODULE.

 * Implements hook_preprocess_html().
function MYMODULE_preprocess_html(&$vars) {
  $node = menu_get_object();

  // Add a new theme suggestion when viewing node's of mynodetype.
  if ($node && $node->nid && $node->type == 'mynodetype') {
    $vars['theme_hook_suggestions'][] = 'html__mynodetype';

 * Implements hook_theme().
function MYMODULE_theme($existing, $type, $theme, $path) {
  $theme = array();

  //Add our templates/html--mynodetype.tpl.php to the theme registry
  $theme['html__mynodetype'] = array(
    'template' => 'html--mynodetype',
    'path' => drupal_get_path('module', 'MYMODULE') . '/templates',
  return $theme;
