   I can not figure out how to apply a filter to a custom query.

   For example:

   <?php
   wp_reset_query();
   $published_query_string = "author=39&post_status=publish";
   $publishedQuery = new WP_Query( $published_query_string );
   while ( $publishedQuery->have_posts() ) : $publishedQuery->the_post();
   	do_some_stuff();
   endwhile;
   ?>

   <?php
   function filter_where_custom() {
   	$where .= " AND (wpostmeta_type.meta_key = 'foo')
   		AND (wpostmeta_type.meta_value = 'bar')";
   	return $where;
   }
   ?>

   <?php
   add_filter('posts_where', 'filter_where_custom');
   ?>

   This will apply the filter to the standard query, but not to this custom one created with new WP_Query.

   I feel like I may need an apply_filters() hook somewhere... help?

   (sorry for the double post)

   Hello, stevenkword

   Place add_filter( 'posts_where', 'filter_where_custom'); just before your custom query.

   Thank you for the reply. I was able to get the code working with a small tweak.

   $published_query_string = "author=$user_id&post_status=publish";
   $publishedQuery = new WP_Query();
   add_filter('posts_where', 'filter_where_custom');
   $publishedQuery->query($published_query_string);
   
   while ( $publishedQuery->have_posts() ) : $publishedQuery->the_post();
   	do_some_stuff();
   endwhile;

   Once I realized I was not including the filters on the page I was working with, think started progressing quite a bit faster. :)
