Okay, what if you have a lot of posts (or maybe custom post type posts) on your blog? How do you manage them in your admin panel? You use search for that, don’t you?
Let me show you a very simple code example, which will add on your posts page a filter by taxonomy terms (like category filter).
And that is the code for your functions.php file:
function rudr_posts_taxonomy_filter() { global $typenow; // this variable stores the current custom post type if( $typenow == 'post' ){ // choose one or more post types to apply taxonomy filter for them if( in_array( $typenow array('post','games') ) $taxonomy_names = array('platform', 'device'); foreach ($taxonomy_names as $single_taxonomy) { $current_taxonomy = isset( $_GET[$single_taxonomy] ) ? $_GET[$single_taxonomy] : ''; $taxonomy_object = get_taxonomy( $single_taxonomy ); $taxonomy_name = strtolower( $taxonomy_object->labels->name ); $taxonomy_terms = get_terms( $single_taxonomy ); if(count($taxonomy_terms) > 0) { echo "<select name='$single_taxonomy' id='$single_taxonomy' class='postform'>"; echo "<option value=''>All $taxonomy_name</option>"; foreach ($taxonomy_terms as $single_term) { echo '<option value='. $single_term->slug, $current_taxonomy == $single_term->slug ? ' selected="selected"' : '','>' . $single_term->name .' (' . $single_term->count .')</option>'; } echo "</select>"; } } } } add_action( 'restrict_manage_posts', 'rudr_posts_taxonomy_filter' );

how can i get post with no category ?w
It’s really works. Thanks a lot.
How to change this for specific category names?
Hi Fabio,
If you need this just for a few specific terms or categories, I recommend you to look at
includeparameter ofget_terms()function.Or, as an option, you can do it in static HTML.
Thank you!
Thank you so much for this post!
Always welcome :)
Did I have to specify something when I create the custom taxonomy or custom post?
Because, the custom taxonomy is add in the filter bar and it appear in the URL when I try it, but it didn’t filter… My list of post stay the same with all the results and I have no error.
Hi Phil,
Maybe you have
pre_get_postsconflict somewhere? By the way, does the search in this post type work?
