I havn’t used any plugin for my custom post types.
Here is the code for my custom post type in question
add_action( 'init', 'register_cpt_product' );
function register_cpt_product() {
$labels = array(
'name' => _x( 'Products', 'product' ),
'singular_name' => _x( 'Product', 'product' ),
'add_new' => _x( 'Add New Products', 'product' ),
'add_new_item' => _x( 'Add New Product', 'product' ),
'edit_item' => _x( 'Edit Product', 'product' ),
'new_item' => _x( 'New Product', 'product' ),
'view_item' => _x( 'View Product', 'product' ),
'search_items' => _x( 'Search Products', 'product' ),
'not_found' => _x( 'No products found', 'product' ),
'not_found_in_trash' => _x( 'No products found in Trash', 'product' ),
'parent_item_colon' => _x( 'Parent Product:', 'product' ),
'menu_name' => _x( 'Products', 'product' ),
);
$args = array(
'labels' => $labels,
'hierarchical' => true,
'description' => 'Add new view and edit Products for your website',
'supports' => array( 'title', 'editor', 'excerpt', 'author', 'thumbnail', 'revisions' ),
'taxonomies' => array( 'Product Categories' ),
'public' => true,
'show_ui' => true,
'show_in_menu' => true,
'menu_position' => 5,
'show_in_nav_menus' => true,
'publicly_queryable' => true,
'exclude_from_search' => false,
'has_archive' => true,
'query_var' => true,
'can_export' => true,
'rewrite' => true,
'capability_type' => 'post'
);
register_post_type( 'product', $args );
}
