1 theming_example.module theming_example_list_page()

The list page callback.

An example page where the output is supplied as an array which is themed into a list and styled with css.

In this case we'll use the core-provided theme_item_list as a #theme_wrapper. Any theme need only override theme_item_list to change the behavior.

Explains how a module declares theme functions, preprocess functions, and templates.

Code

function theming_example_list_page() {
  $items = array(
    t('First item'),
    t('Second item'),
    t('Third item'),
    t('Fourth item'),
  );

  // First we'll create a render array that simply uses theme_item_list.
  $title = t("A list returned to be rendered using theme('item_list')");
  $build['render_version'] = array(
    // We use #theme here instead of #theme_wrappers because theme_item_list()
    // is the classic type of theme function that does not just assume a
    // render array, but instead has its own properties (#type, #title, #items).
    '#theme' => 'item_list',
    // '#type' => 'ul',  // The default type is 'ul'
    // We can easily make sure that a css or js file is present using #attached.
    '#attached' => array('css' => array(backdrop_get_path('module', 'theming_example') . '/theming_example.css')),
    '#title' => $title,
    '#items' => $items,
    '#attributes' => array('class' => array('render-version-list')),
  );

  // Now we'll create a render array which uses our own list formatter,
  // theme('theming_example_list').
  $title = t("The same list rendered by theme('theming_example_list')");
  $build['our_theme_function'] = array(
    '#theme' => 'theming_example_list',
    '#attached' => array('css' => array(backdrop_get_path('module', 'theming_example') . '/theming_example.css')),
    '#title' => $title,
    '#items' => $items,
  );
  return $build;
