How to: Display post based on custom fields with a custom query

February 20, 2009 at 9:36 am

Many readers asked me how to be able to display posts based on custom fields values. If you’re interested to know about it, just read on, I’m going to tell you how to do it!

The first thing to do is to create a page template.

The code below will display your posts, based on the following condition: Post must have a custom field with key tag and value email. Of course, you can change it in the query to make the code fits your needs ;)

Template Name: Custom query

 $querystr = "
    SELECT wposts.* 
    FROM $wpdb->posts wposts, $wpdb->postmeta wpostmeta
    WHERE wposts.ID = wpostmeta.post_id 
    AND wpostmeta.meta_key = 'tag' 
    AND wpostmeta.meta_value = 'email' 
    AND wposts.post_status = 'publish' 
    AND wposts.post_type = 'post' 
    ORDER BY wposts.post_date DESC

 $pageposts = $wpdb->get_results($querystr, OBJECT);
if ($pageposts):
  foreach ($pageposts as $post): 
    // Display your post info. For exemple: the_title();the_exerpt();


Happy coding :)
