add_filter('post_column_taxonomy_links', 'your_custom_function', 10, 3);

function your_custom_function($term_links, $taxonomy, $terms) {
    // your custom code here

    return $term_links;
}

Parameters

  • $term_links (string[]): Array of term editing links.

Examples

add_filter('post_column_taxonomy_links', 'add_custom_link_to_terms', 10, 3);

function add_custom_link_to_terms($term_links, $taxonomy, $terms) {
    foreach ($terms as $term) {
        $term_links[] = '<a href="' . esc_url('https://example.com/' . $term->slug) . '">Custom Link</a>';
    }

    return $term_links;

function add_custom_class_to_term_links($term_links, $taxonomy, $terms) {
    foreach ($term_links as &$link) {
        $link = str_replace('<a ', '<a class="custom-class" ', $link);
    }

    return $term_links;
}

This code adds a custom CSS class to each term editing link in the taxonomy column.

function change_link_target_to_new_tab($term_links, $taxonomy, $terms) {
    foreach ($term_links as &$link) {
        $link = str_replace('<a ', '<a target="_blank" ', $link);
    }

    if ($taxonomy === 'custom_taxonomy') {
        return array();
    }

    return $term_links;
}

This code hides term editing links only for the ‘custom_taxonomy’. All other taxonomies will display their links as usual.
