I think you’ll need to add a posts_join filter, to join the posts and postmeta tables. This link should be helpful: http://codex.wordpress.org/Custom_Queries, in particular this piece of example code: add_filter(‘posts_join’, ‘geotag_search_join’ ); add_filter(‘posts_where’, ‘geotag_search_where’ ); function geotag_search_join( $join ) { global $geotag_table, $wpdb; if( is_search() ) { $join .= ” LEFT JOIN $geotag_table ON ” … Read more
Try <?php wp_reset_query(); ?> after each function. See Function Reference/wp reset query « WordPress Codex
Something like this (not tested): add_filter(‘the_title_rss’, ‘custom_feed_title’); function custom_feed_title($title) { $headline = get_post_meta(get_the_id(), ‘headline’, true); if (!empty($headline)) return $headline; return $title; }
First of all, you should look into using WP_Query for this: http://scribu.net/wordpress/advanced-metadata-queries.html Secondly, to see the results, just do a var_dump() before the return: echo ‘<pre>’; var_dump( $data );

The code I tried to use looks like this: $software = array( ‘post_type’ => ‘software’, ‘meta_query’ => array(‘key’ => ‘legacy’, ‘value’ => 1, ‘compare’ => ‘!=’) ); query_posts($software); But the problem is this query also excludes … Read more

Once you’re in the function that actually prints the html for the metabox, the global $post object should always be set the to current post. Is there a specific reason that you need to know the post_id during init?
You can get it by calling global $wp_query and assigning post->ID to a variable. <?php global $wp_query; $postid = $wp_query->post->ID; echo get_post_meta($postid, ‘top-headline’, true); ?>
In most cases its better to store the meta as a single array and in that save database queries. The only down side to storing the data as an array is it’s nearly impossible to query based on sirealized data. So my rule is if i need to query based on that data the it … Read more
