Seperating custom post type categories from post categories

Hi,

I've registered a custom post type 'download' like so...



// Download's Post Type



add_action( 'init', 'create_post_type' );

function create_post_type() {

	$args = array(

        'labels' => post_type_labels( 'Download' ),

        'public' => true,

        'publicly_queryable' => true,

        'show_ui' => true, 

        'show_in_menu' => true, 

        'query_var' => true,

        'rewrite' => true,

        'capability_type' => 'post',

        'has_archive' => true, 

        'hierarchical' => false,

        'menu_position' => null,

        'menu_icon' => 'http://www.repsolhondateam.com/wp/wp-content/plugins/download-monitor/img/menu_icon.png',

        'supports' => array('title',

            'editor',

            'author',

            'thumbnail',

            'excerpt',

            'comments'

        )

    ); 



	register_post_type( 'download', $args );

}



function post_type_labels( $singular, $plural = '' )

{

    if( $plural == '') $plural = $singular .'s';

    

    return array(

        'name' => _x( $plural, 'post type general name' ),

        'singular_name' => _x( $singular, 'post type singular name' ),

        'add_new' => __( 'Add New' ),

        'add_new_item' => __( 'Add New '. $singular ),

        'edit_item' => __( 'Edit '. $singular ),

        'new_item' => __( 'New '. $singular ),

        'view_item' => __( 'View '. $singular ),

        'search_items' => __( 'Search '. $plural ),

        'not_found' =>  __( 'No '. $plural .' found' ),

        'not_found_in_trash' => __( 'No '. $plural .' found in Trash' ), 

        'parent_item_colon' => ''

    );

}



add_filter('post_updated_messages', 'post_type_updated_messages');

function post_type_updated_messages( $messages ) {

 	global $post, $post_ID;



	$messages['download'] = array(

		0 => '', // Unused. Messages start at index 1.

		1 => sprintf( __('Download updated. <a href="%s">View Download</a>'), esc_url( get_permalink($post_ID) ) ),

		2 => __('Custom field updated.'),

		3 => __('Custom field deleted.'),

		4 => __('Download updated.'),

		/* translators: %s: date and time of the revision */

		5 => isset($_GET['revision']) ? sprintf( __('Download restored to revision from %s'), wp_post_revision_title( (int) $_GET['revision'], false ) ) : false,

		6 => sprintf( __('Download published. <a href="%s">View Download</a>'), esc_url( get_permalink($post_ID) ) ),

		7 => __('Download saved.'),

		8 => sprintf( __('Download submitted. <a target="_blank" href="%s">Preview Download</a>'), esc_url( add_query_arg( 'preview', 'true', get_permalink($post_ID) ) ) ),

		9 => sprintf( __('Download scheduled for: %1$s. <a target="_blank" href="%2$s">Preview Download</a>'),

		// translators: Publish box date format, see http://php.net/date

		date_i18n( __( 'M j, Y @ G:i' ), strtotime( $post->post_date ) ), esc_url( get_permalink($post_ID) ) ),

		10 => sprintf( __('Download draft updated. <a target="_blank" href="%s">Preview Download</a>'), esc_url( add_query_arg( 'preview', 'true', get_permalink($post_ID) ) ) ),

	);



	return $messages;

}

This seems to work nice, but no category's are being displayed for this.

So I added this function to enable categories for my custom post type 'download'...



add_action('init', 'download_add_default_boxes');

function download_add_default_boxes() {

    register_taxonomy_for_object_type('category', 'download');

}

This seemed to work, but as I was adding categories for my 'download' post type, I realized they we're also appearing in my normal post categories.

Is there a way of segregating categories for difference post types?

Person who posts working code will get the prize (if it's possible)

Thanks

Yes, you should create a custom taxonomy and attach it to your new post type. Refer to examples in the Codex:
http://codex.wordpress.org/Function_Reference/register_taxonomy

There are many arguments(some of them similar to those of post type regitstration) but the basic code is one line:
```
<?php register_taxonomy( 'downloads_category', 'download', array( 'hierarchical' => true ) ); ?>
```

Just add this line for adding category (It is custom taxonomy actually) to your custom post type:
```
register_taxonomy("category", array("download"), array("hierarchical" => true, "label" => "Download Category", "rewrite" => true));
```
below this line
```
register_post_type( 'download', $args );
```

There is no way of separating the two uses so you need to create a custom taxonomy for your custom post type:





<?php

//hook into the init action and call create_book_taxonomies when it fires

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



//create two taxonomies, genres and writers for the post type "book"

function create_dl_taxonomy() 

{

  // Add new taxonomy, make it hierarchical (like categories)

  $labels = array(

    'name' => _x( 'Download Categories', 'taxonomy general name' ),

    'singular_name' => _x( 'Download Category', 'taxonomy singular name' ),

    'search_items' =>  __( 'Search Download Categories' ),

    'all_items' => __( 'All Download Categories' ),

    'parent_item' => __( 'Parent Download Category' ),

    'parent_item_colon' => __( 'Parent Download Category:' ),

    'edit_item' => __( 'Edit Download Category' ), 

    'update_item' => __( 'Update Download Category' ),

    'add_new_item' => __( 'Add New Download Category' ),

    'new_item_name' => __( 'New Download Category Name' ),

    'menu_name' => __( 'Download Categories' ),

  ); 	



  register_taxonomy('download_cats',array('dowload'), array(

    'hierarchical' => true,

    'labels' => $labels,

    'show_ui' => true,

    'query_var' => true,

    'rewrite' => array( 'slug' => 'download-cats' ),

  ));





}

Hello

You have to register a custom taxonomy too, example here :

<?php

//hook into the init action and call create_book_taxonomies when it fires

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



//create two taxonomies, genres and writers for the post type "book"

function create_book_taxonomies() 

{

  // Add new taxonomy, make it hierarchical (like categories)

  $labels = array(

    'name' => _x( 'Genres', 'taxonomy general name' ),

    'singular_name' => _x( 'Genre', 'taxonomy singular name' ),

    'search_items' =>  __( 'Search Genres' ),

    'all_items' => __( 'All Genres' ),

    'parent_item' => __( 'Parent Genre' ),

    'parent_item_colon' => __( 'Parent Genre:' ),

    'edit_item' => __( 'Edit Genre' ), 

    'update_item' => __( 'Update Genre' ),

    'add_new_item' => __( 'Add New Genre' ),

    'new_item_name' => __( 'New Genre Name' ),

    'menu_name' => __( 'Genre' ),

  ); 	



  register_taxonomy('genre',array('book'), array(

    'hierarchical' => true,

    'labels' => $labels,

    'show_ui' => true,

    'query_var' => true,

    'rewrite' => array( 'slug' => 'genre' ),

  ));



  // Add new taxonomy, NOT hierarchical (like tags)

  $labels = array(

    'name' => _x( 'Writers', 'taxonomy general name' ),

    'singular_name' => _x( 'Writer', 'taxonomy singular name' ),

    'search_items' =>  __( 'Search Writers' ),

    'popular_items' => __( 'Popular Writers' ),

    'all_items' => __( 'All Writers' ),

    'parent_item' => null,

    'parent_item_colon' => null,

    'edit_item' => __( 'Edit Writer' ), 

    'update_item' => __( 'Update Writer' ),

    'add_new_item' => __( 'Add New Writer' ),

    'new_item_name' => __( 'New Writer Name' ),

    'separate_items_with_commas' => __( 'Separate writers with commas' ),

    'add_or_remove_items' => __( 'Add or remove writers' ),

    'choose_from_most_used' => __( 'Choose from the most used writers' ),

    'menu_name' => __( 'Writers' ),

  ); 



  register_taxonomy('writer','book',array(

    'hierarchical' => false,

    'labels' => $labels,

    'show_ui' => true,

    'update_count_callback' => '_update_post_term_count',

    'query_var' => true,

    'rewrite' => array( 'slug' => 'writer' ),

  ));

}

?>

Than you can add this new taxo to your custom post type "download" like this :



add_action( 'init', 'create_post_type' );

function create_post_type() {

	$args = array(

        'labels' => post_type_labels( 'Download' ),

        'public' => true,

        'publicly_queryable' => true,

        'show_ui' => true, 

        'show_in_menu' => true, 

        'query_var' => true,

        'rewrite' => true,

        'capability_type' => 'post',

        'has_archive' => true, 

        'hierarchical' => false,

        'menu_position' => null,

		'taxonomies' => array( 'genre' ),

        'menu_icon' => 'http://www.repsolhondateam.com/wp/wp-content/plugins/download-monitor/img/menu_icon.png',

        'supports' => array('title',

            'editor',

            'author',

            'thumbnail',

            'excerpt',

            'comments'

        )

    ); 



	register_post_type( 'download', $args );

}

See you !
