Inserting Taxonomy Terms During a Plugin Activation?

by

I’ve been trying various ways of doing this. Basically, I’ve been trying to make it so that a plugin of mine populates the terms of a taxonomy only once during the plugin’s activation. The term populating is done in a function via the wp_insert_terms function. Calling the function straight inside the register_activation_hook doesn’t seem to work and neither does hooking to the init hook using the register_activation_hook. Anyone have any ideas?

Here is a version of my code

//version 1
class vsetup {
     function __construct() {
          register_activation_hook(__FILE__,array($this,'activate'));
          $this->create_taxonomies();
     } 
     function activate() {
          wp_insert_term('Action','genre');
          wp_insert_term('Adventure','genre');
     }
     function create_taxonomies() {
           $genre_args = array( 
            'hierarchical' => true,  
                'labels' => array(
            'name'=> _x('Genres', 'taxonomy general name' ),
            'singular_name' => _x('Genre', 'taxonomy singular name'),
            'search_items' => __('Search Genres'),
            'popular_items' => __('Popular Genres'),
            'all_items' => __('All Genres'),
            'edit_item' => __('Edit Genre'),
            'edit_item' => __('Edit Genre'),
            'update_item' => __('Update Genre'),
            'add_new_item' => __('Add New Genre'),
            'new_item_name' => __('New Genre Name'),
            'separate_items_with_commas' => __('Seperate Genres with Commas'),
            'add_or_remove_items' => __('Add or Remove Genres'),
            'choose_from_most_used' => __('Choose from Most Used Genres')
            ),  
                'query_var' => true,  
            'rewrite' => array('slug' =>'genre')        
           );
           register_taxonomy('genre', 'post',$genre_args);
     }
}

When that didn’t work, I tried doing this:

 //version 2
    class vsetup {
         function __construct() {
              register_activation_hook(__FILE__,array($this,'activate'));
              $this->create_taxonomies();
         } 
         function activate() {
              add_action('init', array($this,'populate_taxonomies'));
         }
          function create_taxonomies() {
               $genre_args = array( 
                'hierarchical' => true,  
                    'labels' => array(
                'name'=> _x('Genres', 'taxonomy general name' ),
                'singular_name' => _x('Genre', 'taxonomy singular name'),
                'search_items' => __('Search Genres'),
                'popular_items' => __('Popular Genres'),
                'all_items' => __('All Genres'),
                'edit_item' => __('Edit Genre'),
                'edit_item' => __('Edit Genre'),
                'update_item' => __('Update Genre'),
                'add_new_item' => __('Add New Genre'),
                'new_item_name' => __('New Genre Name'),
                'separate_items_with_commas' => __('Seperate Genres with Commas'),
                'add_or_remove_items' => __('Add or Remove Genres'),
                'choose_from_most_used' => __('Choose from Most Used Genres')
                ),  
                    'query_var' => true,  
                'rewrite' => array('slug' =>'genre')        
               );
               register_taxonomy('genre', 'post',$genre_args);
         }
         function populate_taxonomies() {
              wp_insert_term('Action','genre');
              wp_insert_term('Adventure','genre');
         }
    }

Neither idea worked for me so far.

Here is the fixed version of your code.

class vsetup {
     function __construct() {
          register_activation_hook(__FILE__,array($this,'activate'));
          add_action( 'init', array( $this, 'create_taxonomies' ) );
     } 
     function activate() {
          $this->create_taxonomies();
          wp_insert_term('Action','genre');
          wp_insert_term('Adventure','genre');
     }
     function create_taxonomies() {
           $genre_args = array( 
            'hierarchical' => true,  
                'labels' => array(
            'name'=> _x('Genres', 'taxonomy general name' ),
            'singular_name' => _x('Genre', 'taxonomy singular name'),
            'search_items' => __('Search Genres'),
            'popular_items' => __('Popular Genres'),
            'all_items' => __('All Genres'),
            'edit_item' => __('Edit Genre'),
            'edit_item' => __('Edit Genre'),
            'update_item' => __('Update Genre'),
            'add_new_item' => __('Add New Genre'),
            'new_item_name' => __('New Genre Name'),
            'separate_items_with_commas' => __('Seperate Genres with Commas'),
            'add_or_remove_items' => __('Add or Remove Genres'),
            'choose_from_most_used' => __('Choose from Most Used Genres')
            ),  
                'query_var' => true,  
            'rewrite' => array('slug' =>'genre')        
           );
           register_taxonomy('genre', 'post',$genre_args);
     }
}

And don’t forget to create the object/instance of the vsetup class i.e new vsetup()

Huh! Forgot to remove the debug statement.
