Adding predefined terms to a taxonomy

Question

I'm writing a plugin for adding a Custom Post called"Dog". The core of the plugin is strictly based on this one https://github.com/RescueThemes/Rescue-Animal-Custom-Posts

I prefer to add predefined sexes after the plugin activation, I would like to add "Male", "Female", "Unapplicable" from the start.

So, based on other resources I wrote that in the same .php plugin file

Consider that I changed the taxonomy name from "Genders" to "Sexes" from the original plugin.

add_action( 'init', 'create_dog_taxonomies', 0 );

function create_dog_taxonomies() {

// Sex taxonomy
    $labels = array( 
    'name' => _x( 'Sexes', 'shelter-dogs' ),
    //etc.
);

    $args = array( 
        'labels' => $labels,
        'public' => true,
        'show_in_nav_menus' => true,
        'show_ui' => true,
        'show_tagcloud' => true,
        'hierarchical' => false,
        'rewrite' => true,
        'query_var' => true
    );

    register_taxonomy( 'dog_sex', array('shelter_dogs'), $args );
}

add_action('init', 'add_sexes', 100);

function add_sexes()
{
    wp_insert_term(
      'Male', // the term 
      'Sexes', // the taxonomy
      array(
        'slug' => 'Male'
      )
    );
}

I get the Sexes taxonomy, but no predefined values. Where's the problem?

Answer 1

Maybe try wp_insert_term once the plugin has been enabled: https://codex.wordpress.org/Function_Reference/wp_insert_term

I.e.

wp_insert_term(
  'Male', // the term 
  'dog_sex', // the taxonomy
  array(
    'slug' => 'male',
  )
);
