Question

New to sql and php and trying to work through this one. After reading several examples here, I still can’t seem to get this done. Right now I have the following query

$sql = "SELECT e.id, e.event_name, e.recurrence_id, e.start_date, e.venue_title FROM " . wp_events_detail . " e  WHERE e.recurrence_id <>0 or e.recurrence_id = 0 and is_active = 'Y' GROUP BY e.event_name, e.start_date"  ;
                $posts = $wpdb->get_results($sql);

                print("<ul>");
                foreach ($posts as $post)
                {
                    print('<li>'.$post->event_name.'|'.$post->event_desc.'<br/>');

                     print('</li>');
                    print($post->start_date. '~' .$post->venue_title.'<br/>'); 
                }
                print("</ul>");

This produces
Name of Class A
Start Date 1
Name of Class A
Start Date 2
Name of Class B
Start Date 1
Name of Class B
Start Date 2

what I would like is
Name of Class A
Start Date 1
Start Date 2

Name of Class B
Start Date 1
Start Date 2

I know I need an array and define rows – Have tried several options with no luck. Not understanding all the variables etc defined in this answer (which seems what I want this to do)

Show year only once in archives loop

Any help greatly appreciated! Even a point in the right direction;-)

Answer 1

you can adjust your for loop to be:

$lastseeneventname='';
foreach ($posts as $post){
   if($lastseeneventname!=$post->event_name){
      print('<li>'.$post->event_name.'|'.$post->event_desc.'<br/>');
      print('</li>');
      $lastseeneventname=$post->event_name;
   }
   print($post->start_date. '~' .$post->venue_title.'<br/>'); 
}

This will only print new event_names once which is what, I think, you want.
