If you're running an educational or quiz-based website, you might want to create a custom post type (CPT) for One Liner Questions. In this guide, we'll walk you through registering a CPT and displaying interactive questions using Advanced Custom Fields (ACF).

Step 1: Registering the "One Liner Question" CPT

The first step is to register a custom post type that allows you to add One Liner Questions easily.

Add the following code to your functions.php file:

function register_one_liner_question_cpt() {
    $labels = array(
        'name'                  => _x('One Liner Questions', 'Post Type General Name', 'text_domain'),
        'singular_name'         => _x('One Liner Question', 'Post Type Singular Name', 'text_domain'),
        'menu_name'             => __('One Liner Questions', 'text_domain'),
        'name_admin_bar'        => __('One Liner Question', 'text_domain'),
        'archives'              => __('One Liner Question Archives', 'text_domain'),
        'attributes'            => __('One Liner Question Attributes', 'text_domain'),
        'all_items'             => __('All One Liner Questions', 'text_domain'),
        'add_new_item'          => __('Add New One Liner Question', 'text_domain'),
        'add_new'               => __('Add New', 'text_domain'),
        'new_item'              => __('New One Liner Question', 'text_domain'),
        'edit_item'             => __('Edit One Liner Question', 'text_domain'),
        'update_item'           => __('Update One Liner Question', 'text_domain'),
        'view_item'             => __('View One Liner Question', 'text_domain'),
        'search_items'          => __('Search One Liner Questions', 'text_domain'),
        'not_found'             => __('Not Found', 'text_domain'),
        'not_found_in_trash'    => __('Not Found in Trash', 'text_domain'),
    );

    $args = array(
        'label'                 => __('One Liner Question', 'text_domain'),
        'description'           => __('Custom post type for One Liner Questions', 'text_domain'),
        'labels'                => $labels,
        'supports'              => array('title', 'editor', 'thumbnail', 'custom-fields', 'excerpt', 'author', 'comments', 'revisions'),
        'hierarchical'          => false,
        'public'                => true,
        'show_ui'               => true,
        'show_in_menu'          => true,
        'menu_icon'             => 'dashicons-lightbulb',
        'show_in_admin_bar'     => true,
        'show_in_nav_menus'     => true,
        'can_export'            => true,
        'has_archive'           => true,
        'rewrite'               => array('slug' => 'one-liner-questions'),
        'capability_type'       => 'post',
        'show_in_rest'          => true,
        'taxonomies'            => array('category', 'post_tag'),
        'exclude_from_search'   => false,
        'menu_position'         => 5,
    );

    register_post_type('one_liner_question', $args);
}
add_action('init', 'register_one_liner_question_cpt');

Explanation:

• Registers a custom post type named "One Liner Questions."

• Adds title, editor, and custom fields support.

• Uses dashicons-lightbulb as the menu icon.

• Enables categories and tags.

Step 2: Adding One Liner Questions with ACF (Advanced Custom Fields)

To store multiple one-liner questions, use Repeater Fields in ACF:

1. Create a new Field Group in ACF and attach it to the "One Liner Question" CPT.

2. Add a Repeater Field named one_liner_questions.

   • Sub-fields:

     • question_text (Text Field)

     • answer_text (Text Field)

3. Save and assign it to the CPT.

Step 3: Displaying One Liner Questions on the Frontend

Now, we will fetch and display these questions in an interactive FAQ format.

Add this function to functions.php:

 function display_one_liner_questions($content) {
    if (is_singular('one_liner_question')) {
        $output = '';
        $question_number = 1;
        
        $output .= '
';

        if (have_rows('one_liner_questions')) {
            $output .= '
';
            while (have_rows('one_liner_questions')) {
                the_row();
                $question_text = get_sub_field('question_text');
                $answer_text = get_sub_field('answer_text');
                
                if ($question_text && $answer_text) {
                    $unique_id = 'question_' . $question_number;
                    $output .= '
';
                    $output .= '
Q' . $question_number . ': ' . $question_text . ' [Show Answer]
';
                    $output .= '
 Ans: ' . $answer_text . '
';
                    $output .= '
';
                    $question_number++;
                }
            }
            $output .= '
';
        } else {
            $output .= '
No questions found.
';
        }

        $output .= '
';

        $content .= $output;
        
        $content .= '';
    }
    return $content;
}
add_filter('the_content', 'display_one_liner_questions');

Explanation:

• Fetches the one-liner questions stored in ACF.

• Displays them in an interactive list format.

• Uses JavaScript to toggle the answer visibility.

Step 4: Styling for Better User Experience

To improve the design, add this CSS to your theme:

#one_liner_section ul {
    list-style: none;
    padding: 0;
}
#one_liner_section li {
    padding: 10px;
    border: 1px solid #ddd;
    margin-bottom: 10px;
    border-radius: 5px;
    background: #f9f9f9;
}
#one_liner_section p {
    font-weight: bold;
    margin: 0;
    color: #333;
}
#one_liner_section span {
    color: #FF5722;
    cursor: pointer;
    font-weight: bold;
}
#one_liner_section div {
    display: none;
    padding: 5px;
    color: #4CAF50;
}
