How to dynamically change the text of the Global: result summary based on exposed filter on Views?

Question

There is a content type and it has a field called field_type. It's a select list and there is 5 options to select such as AAA, BBB, CCC, DDD, EEE.

I'm using the Views module to list the nodes of this content type. I added the field_type as exposed filter for this views.

In the header of the views, I added the Global: Result summary to show result summary.

 "@total results found."

What I want to do is dynamically change the text based on the exposed filter. For example if the AAA is selected on the field_type exposed filter then the results summary should display:

 "@total AAA found."

How can I do that?

Answer 1

This can be done by implementing the hook_views_pre_render and altering the view's header content. Here is a sample code:

/**
 * Implements hook_views_pre_render().
 */
function my_module_views_pre_render(&$view) {
  if ($view->name == 'my_view' && $view->current_display == 'my_display') {
    $indicator = $view->exposed_input['my_filter'] == 1 ? t('AAA ') : t('BBB ');
    $view->header['result']->options['content'] = '<div class="my-class-results">@total <strong><em>' . $indicator . '</strong></em> found</div>';
  }
}

This works with any substitution: @start, @end, @total, @name etc

I took the liberty of writing a little module for accomplishing what you asked for, I found it an interesting problem. You can access it here:
