Add A Column For Custom Taxonomies To Custom Post Type

Tonight I needed to add a column for a custom taxonomy to my “all posts” view of a custom post type. It turns out that WordPress 3.5 made this easy with the show_admin_column parameter for taxonomies.

In my case, I was using Custom Post Type UI to generate the post types and taxonomies, so I could not manually add that parameter. But, have no fear, there is a filter that is easy enough to drop into functions.php of my theme. My code follows:

add_filter( 'manage_taxonomies_for_cards_columns', 'activity_type_columns' );
function activity_type_columns( $taxonomies ) {
    $taxonomies[] = 'card_id';
    return $taxonomies;
}

In my case, “cards” is my custom post type slug, and “card_id” is my custom taxonomy. So, you will need to change “manage_taxonomies_for_cards_columns” to “manage_taxonomies_for_INSERTPOSTTYPESLUGHERE_columns” and change “card_id” to your taxonomy slug.

Here’s what it looks like in action:

Pretty sweet!

How to Connect a GoDaddy Site to ManageWP

By The Mighty Mo! Design Co. | June 27, 2022

GoDaddy owns ManageWP, and, strangely, they make it very difficult to add GoDaddy-managed WordPress sites to their ManageWP service. Thankfully, there’s a quick workaround: Visit https://yoursite.com/wp-admin/plugins.php?showWorker=1 — This will make the ManageWP “Worker” plugin visible. Copy the connection info from the ManageWP Worker plugin. Add the site per-normal on ManageWP. That’s it! I hope this…

The solution was to write a simple function that checks whether or not we’re currently on a login page, and then add a call to that function in my code. Here’s the…
