I need to add a class to the h2 block titles in a sidebar. How can I do this in pre-process? I haven't been able to find an example that shows how to isolate certain blocks. I'm using Omega.

Inspect the block object in this preprocess function. You could use either the 'module' and 'delta' properties to target a specific block or the 'region' property to target all blocks in a certain region.

H2 css-classes are listed in the title_attributes_array. The code below shows how to add a new class. This example is based on a block generated by Views:

function MYTHEME_preprocess_block(&$variables) {
  $block = $variables['block'];
  if ($block->module == 'views' && $block->delta == 'name_of_my_view-block') {
    $variables['title_attributes_array']['class'][] = 'my-new-class';

Sidenote: dpm() by the Devel module is a handy tool for printing out the available data in variables:

function MYTHEME_preprocess_block(&$variables) {
  • Thanks. That did it! Question - is the $variables['block'] value a ref to the $variables['elements']['#block'] array?

  • Can I wrap the h2 tag in another div, or do I need to do that in a block template file? I need to style the h2 titles with a ribbon using CSS.
