Breadcrumb with taxonomy path

Question

I use the theme "Bootstrap".

When I display a node, there is no breadcrumb. My nodes are related to taxonomy terms.

On the screenshots :

Boutique / Les chocolats BIO

The second screenshot should be :

Boutique / Les chocolats BIO / Tablette de chocolat noir artisanale BIO aux épices tchaï

"Boutique" is the vocabulary of taxonomy and "Les chocolats BIO" is the terms of taxonomy.

How to display the breadcrumb on the nodes without using any additional modules ?

Answer 1

you can implement hook_node_view and make alterations in the breadcrump eg:

/*
 * Implements hook_node_view().
 */
function my_custom_module_node_view($node, $view_mode) {
  if ($node->type == 'my-node-type') {
    $type == $node->field_test_field['und'][0]['value'];
    if ($type == 0) {
      $breadcrumb = drupal_get_breadcrumb();
      $breadcrumb[1] = 'new breadcrumb';
      drupal_set_breadcrumb($breadcrumb);
    }
  }
}
