Language Handling

by

The free version of the WordPress Polylang plugin does not include the language support in the REST API. With the assistance of ChatGPT-4o I added the following php-code at the end of the theme functions.php file :

add_action( 'rest_api_init', function () {
    register_rest_field( 'post',
        'translations',
        array(
            'get_callback' => function( $post_arr ) {
                return function_exists( 'pll_get_post_translations' )
                    ? pll_get_post_translations( $post_arr['id'] )
                    : null;
            },
            'schema' => null,
        )
    );
});

Here is the resulting JSON response when fetching a WordPress post in english, with translations in fr, de, pt and lb.

Ask your AI helper : difficulty levels of a quiz

by

Question to ChatGPT-4o :

how to describe the difficulty of a quiz ?

Answer of ChatGPT-4o :

To describe the difficulty levels of a quiz clearly and progressively, you can use a graded scale with commonly understood labels. Here’s a well-structured set of terms, from easiest to hardest:

Standard Quiz Difficulty Levels

  1. Very Easy
  2. Easy
  3. Moderate
  4. Difficult
  5. Very Difficult

Optional Alternatives (if you want to vary tone or context):

For a friendlier, more casual app:

  • Beginner
  • Basic
  • Intermediate
  • Challenging
  • Expert

For a gamified or playful experience:

  • Warm-up
  • Casual
  • Thinker
  • Tough Nut
  • Mastermind

You can also add icons or color cues to make it more intuitive:

  • 🔹 Very Easy (green or 1 star)
  • 🔸 Moderate (yellow or 3 stars)
  • 🔺 Very Difficult (red or 5 stars)
