自定义发布类型分类法和消息

Posted 2021-02-24

This gives the code for creating a custom post type with all the necessary labels and even custom message support, and it gives the code for a custom taxonomy with that post type.

// The register_post_type() function is not to be used before the 'init'.
add_action( 'init', 'my_custom_init' );
 
/* Here's how to create your customized labels */
function my_custom_init() {
	$labels = array(
		'name' => _x( 'Portfolio Galleries', 'post type general name' ), // Tip: _x('') is used for localization
		'singular_name' => _x( 'Portfolio Gallery', 'post type singular name' ),
		'add_new' => _x( 'Add New', 'Portfolio Gallery' ),
		'add_new_item' => __( 'Add New Portfolio Gallery' ),
		'edit_item' => __( 'Edit Portfolio Gallery' ),
		'new_item' => __( 'New Portfolio Gallery' ),

		'search_items' => __( 'Search Portfolio Galleries' ),
		'not_found' =>  __( 'No Portfolio Galleries found' ),
		'not_found_in_trash' => __( 'No Portfolio Galleries found in Trash' ),

	);

	); 
 
	register_post_type( 'portfolio-gallery', $args ); /* Register it and move on */
}
//add a custom message to the post message function
 
add_filter('post_updated_messages', 'gallery_updated_messages');
function gallery_updated_messages( $messages ) {
 
  $messages['portfolio-gallery'] = array(
    0 => '', // Unused. Messages start at index 1.
    1 => sprintf( __('Gallery updated. <a href="%s">View Gallery</a>'), esc_url( get_permalink($post_ID) ) ),
    2 => __('Custom field updated.'),
