If you only need to get this information, you can use template_preprocess_views_view
/**
* Preprocess the primary theme implementation for a view.
*/
function YOURTHEME_preprocess_views_view(&$vars) {
$view = $vars['view'];
switch ($view->name) {
case 'your_view_name' :
// print out the array with all options to see what you're dealing with
drupal_set_message('<pre>' . print_r($view->display['display_name']->display_options, true) . '</pre>');
break;
}
}
But if you will need to override this custom class, you'll need to use hook_views_pre_render()
function YOURTHEME_views_pre_render(&$view) {
switch ($view->name) {
case 'name_of_your_view' :
// override the view settings
// for example: $view->field['fieldname']->options['label'] = 'Some label';
break;
}
}
