I am trying to add a column to one of my custom post types, but only on the edit taxonomy page.
I have a taxonomy registered called "event-categories" for my custom post type "events".
I can successfully add the custom column to the custom post type edit screen, but can't seem to get the hook to work on the edit taxonomy page.
Digging through some of the core, I was able to locate the hook
$taxonomies = apply_filters( "manage_taxonomies_for_{$post_type}_columns", $taxonomies, $post_type );
inside of class-wp-posts-list-table.php which would lead me to believe it is possible to hook into, and add custom columns to this page. But when hooking in to add the column, nothing actually happenes.
function events_color_column($defaults) {
$defaults['event_cat_color'] = 'Event Category Color';
return $defaults;
}
function events_column_content($column_name, $post_ID) {
if ($column_name == 'event_cat_color') {
echo 'Event Color : #2432';
}
}
add_filter('manage_taxonomies_for_events_columns', 'events_color_column');
add_action('manage_taxonomies_for_events_column', 'events_color_column_content', 10, 2);
but if I simply change the filter+action to 'manage_events_columns' and 'manage_events_column' things work on the custom post type screen.
Can someone see what I am doing wrong here, or is this a bug that needs to be patched in core?
Edit:
I was able to hook into the custom taxonomy page to display the column header, by doing the following:
To any one else facing similar issues, you need to pass in the page ID. For me, the following worked:
add_filter('manage_edit-event_categories_columns', 'events_color_column');
But I can't seem to figure out why the content isn't printing into each column using
add_action('manage_edit-event_categories_custom_column', 'events_color_column_content', 10, 2);
I have also tried passing in the taxonomy name, the post type name, but nothing seems to work. What am I missing here?

The final working hooks that I was able to work out are:
// adding an extra column to the event_cateogires page
// to display the color
function events_color_column($defaults) {
$defaults['event_cat_color'] = 'Event Category Color';
return $defaults;
}
function events_color_column_content($column_name, $post_ID) {
echo 'Event Color : #2432';
}
add_filter('manage_edit-event_categories_columns', 'events_color_column');
add_action('manage_event_categories_custom_column', 'events_color_column_content', 10, 2);
Using the
if ($column_name == 'event_cat_color') {
echo 'Event Color : #2432';
}
didn't seem to work with this action hook. Removing the conditional, and just echoing things out seems to work.
minor issues in your code that need to be corrected
In the add_action call, you are using the wrong function name
events_color_column_content instead of events_column_content
The hook you are using should be manage_edit-{taxonomy}_custom_column for custom taxonomy columns, not manage_edit-{taxonomy}_columns.
function events_color_column($columns) {
$columns['event_cat_color'] = 'Event Category Color';
return $columns;
}
function events_column_content($content, $column_name, $term_id) {
if ($column_name == 'event_cat_color') {
$content = 'Event Color : #2432';
}
return $content;
}
add_filter('manage_edit-event_categories_columns', 'events_color_column');
add_action('manage_event_categories_custom_column', 'events_column_content', 10, 3);
To display a custom column in the admin panel for a Custom Post Type (CPT) taxonomy, you can use the following steps:
Hook into the manage_edit-{$taxonomy}_columns filter to add a new column. Replace {$taxonomy} with your taxonomy slug.
add_filter('manage_edit-your_taxonomy_columns', function ($columns) {
$columns['custom_column'] = __('Custom Column'); // Add your column
return $columns;
});
Hook into the manage_{$taxonomy}_custom_column action to display data in the new column.
add_action('manage_your_taxonomy_custom_column', function ($content, $column_name, $term_id) {
if ('custom_column' === $column_name) {
$custom_data = get_term_meta($term_id, 'custom_meta_key', true); // Replace with your meta key
$content = $custom_data ? esc_html($custom_data) : __('No data');
}
return $content;
}, 10, 3);
To make the column sortable, use the manage_edit-{$taxonomy}_sortable_columns filter.
add_filter('manage_edit-your_taxonomy_sortable_columns', function ($sortable) {
$sortable['custom_column'] = 'custom_meta_key'; // Replace with your meta key
return $sortable;
});
Replace your_taxonomy with your taxonomy slug and custom_meta_key with the meta key used to store the data.
If you have a taxonomy product_category and want to show a custom field extra_info in the admin columns:
// Add the column
add_filter('manage_edit-product_category_columns', function ($columns) {
$columns['extra_info'] = __('Extra Info');
return $columns;
});
// Populate the column
add_action('manage_product_category_custom_column', function ($content, $column_name, $term_id) {
if ('extra_info' === $column_name) {
$extra_info = get_term_meta($term_id, 'extra_info', true);
$content = $extra_info ? esc_html($extra_info) : __('No data');
}
return $content;
}, 10, 3);
This will display a column with your custom meta data in the taxonomy admin screen.
