WHA Tours Core

WHA Tours Core keeps the content structure of a tour operator site in a plugin, so it survives a theme switch, as required by the WordPress.org theme guidelines.

The plugin registers:

• The Tour post type (archive at /tours/, single tours at /tour/<slug>/), with title, editor, excerpt, featured image and revisions, available in the block editor and the REST API.
• Three taxonomies: Tour Categories (hierarchical), Seasons and Countries.
• Tour fields: days, transport, price, route stops, departure dates with availability status, and a “season hit” flag. The next departure date is computed automatically and used for sorting.
• Category fields: image, short description and a colour key. Seasons have a sort order.
• A demo content importer under Tours → Import demo content (and wp wha-tours demo import), which fills a fresh site with a sample catalogue: four categories, four seasons, eleven countries, twelve tours with CC0 photographs, four pages, two menus, the Customizer settings of the WHA Tour Poster theme and the Reading settings. It never overwrites existing content and creates no duplicates when it is run twice.
• A lead form as the [wha_tours_lead_form] shortcode and as the Lead form block. Submissions are checked against a nonce, a honeypot field and a one-minute-per-IP rate limit, emailed to the site administrator and stored as private Leads entries in the admin.

Template helpers for theme authors: wha_tours_core_get_meta(), wha_tours_core_get_tours(), wha_tours_core_get_term_image_id(), wha_tours_core_next_date(), wha_tours_core_format_dates(), wha_tours_core_transport_label(), wha_tours_core_transport_icon(), wha_tours_core_category_color() and wha_tours_core_price_label().

Developer notes

• Meta key prefix. All tour and term meta registered by the plugin uses the _wha_tour_ prefix
  (_wha_tour_days, _wha_tour_transport, _wha_tour_price, _wha_tour_route,
  _wha_tour_dates, _wha_tour_hit, _wha_tour_next_departure, _wha_tour_image,
  _wha_tour_image_id,
  _wha_tour_short_desc, _wha_tour_color, _wha_tour_order). That prefix is shared with the
  WHA Tour Poster theme, which reads the same keys directly when it renders poster cards and season tabs, so
  renaming a key here breaks the theme templates. The lead entries use _wha_tours_core_lead_*
  instead, because nothing outside this plugin reads them.
• Lead post type. Submitted requests are stored in the wha_tours_lead post type. WordPress limits a
  post type name to 20 characters, so the name cannot carry the full wha_tours_core_ prefix;
  wha_tours_lead is the prefixed short form and is registered private, with no public archive.

Resources

• CMB2 v2.13.0 — https://github.com/CMB2/CMB2 — GPL-2.0-or-later, bundled in vendor/cmb2/cmb2,
  unmodified, except that three groups of files it does not need here are left out of the package:

1. The wp-color-picker-alpha files (js/wp-color-picker-alpha.js and
   js/wp-color-picker-alpha.min.js). CMB2 only registers that script for colorpicker fields, which
   this plugin does not use, and the plugin additionally removes the wp-color-picker-alpha handle
   through the cmb2_script_dependencies filter.
2. jQuery UI Timepicker Addon (js/jquery-ui-timepicker-addon.min.js, v1.5.0), which CMB2 registers
   as jquery-ui-datetimepicker for the text_time and text_datetime_timestamp field types. This
   plugin only uses text_date, and the same filter removes that handle too.
3. CMB2’s own translation files (languages/). They belong to the cmb2 text domain, not to this
   plugin, and WordPress loads them from translate.wordpress.org wherever CMB2 is installed as a
   plugin of its own.
