I have a view that show all contents of type NEWS NEWS has like fields :

Content = Title

Scheduler = publish-on

and in sort criteria : I want sort contents with two option : With scheduler (publish-on = DESC) and With post date

I want sort content with scheduler, and when scheduler field is empty he sort with post date. I have created hook views query alter and I have a problem, how can I sort field with condition if publish_on is empty then sort with postdate

function custom_sort_views_query_alter(&$view, &$query) {


    if($view->name === 'articleview') {
        $view->query->add_where(1,'publish_on',  'NOT IN');
        $view->query->orderby[0]['field'] = "CASE WHEN publish_on IS NULL THEN created ELSE publish_on END";
        $view->query->orderby[0]['direction'] = "DESC";
        $view->query->orderby[1]['field'] = "created";
        $view->query->orderby[1]['direction'] = "DESC";
    }
}
  • publish_on empty for some records or for all records? – Adrian Cid Almaguer Feb 4 '16 at 0:10
  • for some records – Salaktarus Feb 4 '16 at 0:12
  • Then if some records have the publish_on field empty sort all the records with postdate? – Adrian Cid Almaguer Feb 4 '16 at 0:19
  • if some records have the publish_on field empty sort those empty records with postdate, and records who have publish_on field not empty sort with publish_on field ! – Salaktarus Feb 4 '16 at 0:21
  • and you use postgres or mysql? – Adrian Cid Almaguer Feb 4 '16 at 0:25

The solution that comes to my mind now (after your question's comments) is make two queries, one query with the records that have publish_on field empty and the other with the field non empty and then use a UNION between them.

Why this? AFAIK You can't sort some records in a query based in a condition and other records based in another condition, so to achieve this you must split the records and apply the sort method separately. This is records of a condition first and records of another condition before, but you can't merge the records and the order condition.

  • like this ? : function custom_sort_views_query_alter(&$view, &$query) { if($view->name === 'articleview') { $date1 = $view->query = "publish_on"; $date2 = $view->query = "created";; if(!empty($date1)){ $view->query->orderby[0]['field'] = "publish_on"; $view->query->orderby[0]['direction'] = "DESC"; }else{ $view->query->orderby[1]['field'] = "created"; $view->query->orderby[1]['direction'] = "DESC"; } } } – Salaktarus Feb 4 '16 at 0:57
  • @Salaktarus I edit with aditional info – Adrian Cid Almaguer Feb 4 '16 at 1:07
  • ok, but i don't understand what you means when you say : so to achieve this you must split the records and apply the sort method separately. – Salaktarus Feb 4 '16 at 1:13
  • the problem is postdate has a field in table at database and publish_on from other table – Salaktarus Feb 4 '16 at 1:21
