Views exposed filters button HTML5 validation issues

If you care for HTML5 validation in Drupal 7, prepare to face several issues. One of these issues is having an exposed filter in a view with a submit button. The button by default has an empty name, thus not passing HTML5 validation. See the relevant issue here in the Drupal issue queue:

Empty ‘name’ value for the exposed filter submit button

Comment 4 on the previous link may do the job fine, but I only needed to just add a name in my submit button so I used a simpler version of this:

function THEME_button($variables) {
  if ($variables['element']['#id'] === 'ID-OF-MY-SUBMIT-BUTTON') {
    $variables['element']['#attributes']['name'] = 'Search';
  }
  return '<input' . drupal_attributes($variables['element']['#attributes']) . ' />';
}

Be sure to change THEME with your theme name and ID-OF-MY-SUBMIT-BUTTON with the ID of your submit button (doh!).

Drupal aggregated Views: Sort by number of records AND alphabetically

Let’s say you need to have a view with the most used tags in your site. For this you would normally create a taxonomy term view, add a contextual filter for the term name, and sort by number of records so term aggregation will take place with the most used tags first.

Drupal: Aggregate by number of records in a taxonomy term view

 

So your view will generate the most used tags in your content. This is useful for a Tag Cloud implementation.

But what if you needed the aggregated terms to be sorted alphabetically? As you can see from the above screenshot, you can sort only in one of two ways; alphabetically or by number of records.

The following snippet takes care of this problem. Place it in a hook_prerender hook and it will sort the terms alphabetically after doing the aggregation by number of records.


/**
* Implements hook_views_pre_render().
*/
function MYMODULE_views_pre_render(&$view) {
  // Sort the aggregated views results alphabetically since the view won't allow it if we select to sort by .
  if ($view->name === 'view_name') {
    $taxonomy_term_data_node_name = array();
    foreach ($view->result as $key => $row) {
      $taxonomy_term_data_node_name[$key] = $row->taxonomy_term_data_node_name;
    }
    array_multisort($taxonomy_term_data_node_name, SORT_ASC,SORT_NATURAL|SORT_FLAG_CASE, $view->result);
  }
}

Obviously, you have to replace the MYMODULE with your custom module name and view_name with the machine name of your view.
