WordPress Development Patterns

This skill covers common WordPress development patterns including Custom Post Types, taxonomies, meta boxes, REST API endpoints, Settings API, cron, transients, and enqueue patterns.

Custom Post Types

add_action( 'init', 'myplugin_register_post_types' );

function myplugin_register_post_types(): void {
    $labels = array(
        'name'               => _x( 'Events', 'post type general name', 'myplugin' ),
        'singular_name'      => _x( 'Event', 'post type singular name', 'myplugin' ),
        'menu_name'          => _x( 'Events', 'admin menu', 'myplugin' ),
        'add_new'            => _x( 'Add New', 'event', 'myplugin' ),
        'add_new_item'       => __( 'Add New Event', 'myplugin' ),
        'edit_item'          => __( 'Edit Event', 'myplugin' ),
        'new_item'           => __( 'New Event', 'myplugin' ),
        'view_item'          => __( 'View Event', 'myplugin' ),
        'search_items'       => __( 'Search Events', 'myplugin' ),
        'not_found'          => __( 'No events found.', 'myplugin' ),
        'not_found_in_trash' => __( 'No events found in Trash.', 'myplugin' ),
    );

    $args = array(
        'labels'              => $labels,
        'public'              => true,
        'publicly_queryable'  => true,
        'show_ui'             => true,
        'show_in_menu'        => true,
        'show_in_rest'        => true,   // Required for Gutenberg
        'query_var'           => true,
        'rewrite'             => array( 'slug' => 'events' ),
        'capability_type'     => 'post',
        'has_archive'         => true,
        'hierarchical'        => false,
        'menu_position'       => 20,
        'menu_icon'           => 'dashicons-calendar-alt',
        'supports'            => array( 'title', 'editor', 'thumbnail', 'excerpt', 'custom-fields' ),
    );

    register_post_type( 'myplugin_event', $args );
}

Custom Taxonomies

add_action( 'init', 'myplugin_register_taxonomies' );

function myplugin_register_taxonomies(): void {
    $labels = array(
        'name'              => _x( 'Event Types', 'taxonomy general name', 'myplugin' ),
        'singular_name'     => _x( 'Event Type', 'taxonomy singular name', 'myplugin' ),
        'search_items'      => __( 'Search Event Types', 'myplugin' ),
        'all_items'         => __( 'All Event Types', 'myplugin' ),
        'edit_item'         => __( 'Edit Event Type', 'myplugin' ),
        'update_item'       => __( 'Update Event Type', 'myplugin' ),
        'add_new_item'      => __( 'Add New Event Type', 'myplugin' ),
        'new_item_name'     => __( 'New Event Type Name', 'myplugin' ),
        'menu_name'         => __( 'Event Types', 'myplugin' ),
    );

    register_taxonomy( 'myplugin_event_type', array( 'myplugin_event' ), array(
        'hierarchical'      => true,
        'labels'            => $labels,
        'show_ui'           => true,
        'show_admin_column' => true,
        'show_in_rest'      => true,
        'query_var'         => true,
        'rewrite'           => array( 'slug' => 'event-type' ),
    ) );
}
