You can actually just create a custom template file in your theme folder named category-{slug}.php to get a custom look for that category. Example: If your category was ‘Dogs’ and the slug you set for it was ‘dog’, … Read more
Below is code that works: function untag_posts($post_ids, $tags) { global $wpdb; if(! is_array($post_ids) ) { $post_ids = array($post_ids); } $in_post_ids = implode(“‘,'”, $post_ids); if(! is_array($tags) ) { $tags = array($tags); } $in_tag_names = “‘” . implode(“‘,'”, $tags) . “‘”; $query = “SELECT tt.term_taxonomy_id ” . ” from $wpdb->terms as t ” . ” JOIN $wpdb->term_taxonomy … Read more

Or because you don’t update your software and they leverage some of the security holes that have been found and patched. Here’s a set of slides that go indepth to explaining how … Read more
It’s because you’re not registering them as a media type. Every upload is a WordPress post of the attachment type. To start, it would be something like this: $file_name=”Some Name”; $file_path=”/path/to/uploads/2012/08/04/newfile.jpg”; $file_url=”http://url/to/uploads/2012/08/04/newfile.jpg”; $wp_filetype = wp_check_filetype($file, null); $attachment = array( ‘guid’ => $file_url, ‘post_mime_type’ => $wp_filetype[‘type’], ‘post_title’ => $file_name, ‘post_status’ => ‘inherit’, ‘post_date’ => date(‘Y-m-d H:i:s’) … Read more
