Custom title for Taxonomy admin column name

I just noticed that in the 2nd screenshot I highlighted the wrong Menu item – “Technical Skills”. I meant to highlight “Categories” instead, pointing to “Team Member categories” column.

Unless I’m mistaken and those can be customized via the standard labels options available to register_post_type() and register_taxonomy() it’s probably not possible with CPTUI as is. We focus on being as great of a UI as we can be to handle what gets passed to those two functions.

With that said, I’m not sure how easy and accessible amending and filtering those spots would be, if possible at all via plugin. I’d need to try and dig into core to see, and then evaluate how easy it’d be. That said, I’m also not set on the idea of adding anything for this as part of the free plugin here. Tutorial? Sure, I’d write one up, but we try to keep CPTUI’s focus pretty straightforward.

I see what you mean. The get_taxonomy_labels() doesn’t seem to have an option for an Admin Column label by default, which is a shame.

Seems like it would be super simple to tap into the taxonomy_labels_{$taxonomy} filter to add a taxonomy admin column label item into the labels array and then manage_{$post_type}_posts_columns filter to display it.

But I understand, if it doesn’t fall into the scope of your plugin & if you wouldn’t want to add this functionality.

I do think it would’ve added a nice little touch, since it’s a shame that the admin column names for taxonomies get so unwieldy.

If anything, I’d probably add it more to our docs area currently seen at https://docs.pluginize.com/category/126-custom-post-type-ui at least once worked out some sample code to work with.

Here is what I’ve done. Didn’t even need to use the taxonomy_labels_{$taxonomy} filter, cos that just adds unnecessary complexity. Everything can be done just with manage_{$post_type}_posts_columns.

The code below requires at PHP 5.3+, because I used PHP closures to make the code more re-useable.

function define_cpt_taxonomy_admin_column_names() {
  // List of CPTs that need custom columns
  $cpts = array(
    'cpt_1_slug' => array(
      'cpt_1_taxonomy_1_slug' => 'CPT 1 Taxonomy 1 Admin Column Name',
      'cpt_1_taxonomy_2_slug' => 'CPT 1 Taxonomy 2 Admin Column Name',
      'cpt_1_taxonomy_3_slug' => 'CPT 1 Taxonomy 3 Admin Column Name',
    ),
    'cpt_2_slug' => array(
      'cpt_2_taxonomy_1_slug' => 'CPT 2 Taxonomy 1 Admin Column Name',
    ),
  );

  // Loop through each CPT & create a filter to feed appropriate column names for each taxonomy
  foreach( $cpts as $cpt_slug => $taxonomies ) {
    foreach( $taxonomies as $taxonomy_slug => $admin_column_name ) {
      add_filter( "manage_{$cpt_slug}_posts_columns", function( $post_columns ) use ( $taxonomy_slug, $admin_column_name ) {
        $post_columns["taxonomy-{$taxonomy_slug}"] = $admin_column_name;

        return $post_columns;
      }, 10, 3 );
    }
  }
}
define_cpt_taxonomy_admin_column_names();

The only thing someone will need to modify is $cpts array to provide a list of desired custom post types, with their list taxonomies that need custom Admin Column names.

5.3+ should be no issue for at least people using current CPTUI, as we have a minimum requirement of PHP 5.6

Looks legit otherwise. Thanks for typing up what you used, and hopefully it proves helpful for someone else.
