I have a page view that has a couple filters which are not exposed to the user. Users are not to have control over them, but they should able to change at render time. I did something like this a year and a half ago but completely forget the process.

Is it possible to execute a new filter at the preprocess stage? I am doing the following below and it seems to be having no effect.

E.g

function MYTHEME_preprocess_views_view(&$vars) {

  if ($vars['name'] == 'MyDisplay') {
     $display_id = $vars['display_id'];  
     switch ($display_id) {
       case 'page_2':
         $view = $vars['view'];
         $filter = $view->get_item($display_id,'filter','field_story_news_type_value_many_to_one');
         $filter['value']['value'] = 2;
         $view->set_item($display_id,'filter','field_story_news_type_value_many_to_one',$filter);
 
        $view->execute_display();

         $vars['view'] = $view;
         break;
     }    
  }

}

At render time the filters are already processed, the query created and executed and results have been rendered.

You can't go back in time.

Merlin,

Thanks for quick response. Can we modify arguments before rendering then and moving it into a module? I have tried converting my filters to arguments instead and the hooked into pre_render with no results? Any suggestions?

Thanks

function MYMODULE_views_pre_render(&$view) {
  
  if ($view->name == 'CustomPageViews') {
   
    $display_id = $view->current_display;  
     switch ($display_id) {
       case 'page_2':
         // the view takes 2 arguments - trying to force the second argument to the value "5" before rendering
         $view->set_arguments(array('all','5'));
         $view->is_cacheable = FALSE;
         $view->execute();

         // devel seems to still show no argument set for the second argument at this point? :(
         print kpr($view->argument['field_story_news_type_value']);

         break;
     }  

  }
}

Resolved.

Same code as above but using the following hook instead resolves the issue.

function MYMODULE_views_pre_view(&$view) {...}
