Custom Post Types & Categories/Tags

[seth17]

I've created a custom post type called "Projects". I'm trying to get the categories and tags meta boxes to display in the content editor. So far no luck. Not sure what's wrong. Here's the code I've got:

PHP Code:

$labels = array(
    'name' => _x( 'Projects' ),
    'singular_name' => _x( 'project' ),
    'add_new' => _x( 'Add New Project' ),
    'add_new_item' => __( 'Add New Project' ),
    'edit' => __('Edit Project'),
    'edit_item' => __( 'Edit Project' ),
    'new_item' => __( 'New Project' ),
    'view' => __( 'View Project' ),
    'view_item' => __( 'View Project' ),
    'search_items' => __( 'Search Projects' ),
    'all_items' => __( 'All Projects' ),
    'not_found' => __( 'No Projects Found.' ),
    'not_found_in_trash' => __( 'No Projects Found in Trash.' ),
    'parent' => __('Projects'), 
    'menu_name' => __( 'Projects' ),
    'parent_item_colon' => ''
);
$args = array(
    'labels' => $labels,
    'public' => true,
    'publicly_queryable' => true,
    'exclude_from_search' => false,
    'show_ui' => true,
    'menu_position' => 5,
    'menu_icon' => null,
    'capability_type' => post,
    'hierarchical' => true,
    'supports' => array('title', 'editor', 'comments', 'thumbnail', 'excerpt', 'custom-fields', 'revisions', 'page-attributes', 'categories', 'genesis-seo', 'genesis-layouts', ),
    'taxonomies' => array('post_tag', 'category', ),
    'has_archive' => true,
    'rewrite' => array('slug' => projects, 'with_front' => true, ),
    'query_var' => true,
    'can_export' => true,
    'show_in_nav_menus' => true,
);

register_post_type('projects', $args);

Your code looks fine to me, but:

1. Have you hooked that function to 'init'?

2. Assuming yes, have you checked the Screen Options tab in the editor to make sure the metaboxes are visible?

[seth17]

I've check the screen options and it's not there, so it's probably the fact I haven't hooked it to 'init'. I'm not quite sure how to do that. The code above is all I've added for the CPT.

[adew]

You have to register CPT after the taxonomies have been created, hence you need to hook to init.

Do this:

PHP Code:

add_action( 'init', 'init_my_cpt' );
function init_my_cpt() {

// paste all your existing code here
}

Thanks Ade, that's just what I needed. Works great. Apparently the tutorial I followed previously had left that part out.

Got another question. In the CPT editor, blog categories and tags are displaying. I was hoping this would create a new taxonomy for the cpt, (so that I could create specific categories for the cpt), but it appears to just be using what's already there. Is there something else I need to do make it behave like that?
