Modified WordPress functionality

Air helper also modifies default WordPress behavior to make it more suitable for customer projects, forcing our personal preferences and making sure that all the un-neccesary information is hidden or unreachable.

All of these modifications can be altered and/or disabled with hooks. Please see inc/hooks.php for references.

  • Disable REST API users endpoint
  • Remove admin bar in front-end when not on development envarioment
  • Add envarioment marker to admin bar
  • Remove the additional CSS section from customizer
  • Show TinyMCE second editor tools row by default
  • Strip unwanted html tags from titles and menu items

Localization and Polylang support

Air helper adds fallbacks for widely used Polylang functions, so you can use those event if there's no Polylang or multilanguage support needed in project at the time. This saves heck lot of a time when client want's multilanguage support later on.

These functionalities are quite direct copies from Aucor starter because why invent the wheel again ;) Please see their documentation about localization helpers.

Post meta revisions

WordPress does not revision post meta by default and Air helper makes this possible if needed. It also adds possibility to preview meta changes before publishing or updating posts.

At the moment post meta isn't revisioned automatically, you need to register your choice of meta fields for revisioning manually.

function air_helper_example_meta_revisions( $keys ) {
    $keys['_subtitle'] = true; // key is the name of your meta field
    $keys['_location'] = 'map'; // if you use CRB and field is map, tell it
    $keys['_persons'] = 'complex'; // and same goes if fiels type is complex
    return $keys;
add_filter( 'wp_post_revision_meta_keys', 'air_helper_example_meta_revisions' );

Meta revisions are served only when using get_post_meta for simple key=>value fields or dude_get_post_meta for Carbon Fields complexed fields.

WooCommerce support

Plugin will detect if current theme support WooCommerce and if so, loads the most basic overrides and makes Air based theme compatible with WooCommerce. This feature is built for starting point only.
