How to develop a WordPress plug-in that automatically generates a question and answer system

Introduction:
In the modern Internet era, question and answer websites have become more and more popular. In order to meet users' needs for questions and answers, this article will introduce how to develop a WordPress plug-in that automatically generates a question and answer system. With this plugin, you can easily create a Q&A platform to make your website more interactive and attractive.

Step 1: Create a custom post type (Post Type)
In WordPress, a custom post type is a function that can extend the default posts and pages. We need to create a custom data type called "Question".

function create_question_post_type() {
  $labels = array(
    'name' => 'Questions',
    'singular_name' => 'Question',
    'add_new' => 'Add New',
    'add_new_item' => 'Add New Question',
    'edit_item' => 'Edit Question',
    'new_item' => 'New Question',
    'view_item' => 'View Question',
    'search_items' => 'Search Questions',
    'not_found' => 'No questions found',
    'not_found_in_trash' => 'No questions found in trash',
    'parent_item_colon' => '',
    'menu_name' => 'Questions'
  );

  $args = array(
    'labels' => $labels,
    'public' => true,
    'has_archive' => true,
    'rewrite' => array('slug' => 'questions'),
    'supports' => array('title', 'editor', 'author')
  );

  register_post_type('question', $args);
}

add_action('init', 'create_question_post_type');
Copy after login

Step 2: Create meta fields for questions and answers (Meta Fields)
We need to add some additional information fields to questions and answers, such as the category of the question, the author of the answer, etc. By adding metafields we can add and manage these additional fields of information when editing questions and answers.

function add_question_meta_fields() {
  add_meta_box('question_category', 'Category', 'question_category_callback', 'question', 'side', 'default');
}

function question_category_callback($post) {
  $value = get_post_meta($post->ID, 'question_category', true);
  echo '<input type="text" name="question_category" value="' . esc_attr($value) . '" />';
}

function save_question_meta_fields($post_id) {
  if (array_key_exists('question_category', $_POST)) {
    update_post_meta(
      $post_id,
      'question_category',
      sanitize_text_field($_POST['question_category'])
    );
  }
}

add_action('add_meta_boxes_question', 'add_question_meta_fields');
add_action('save_post_question', 'save_question_meta_fields');
Copy after login

Step 3: Create a Q&A system template
We need to create a Q&A system template to display questions and answers. We can do this using a WordPress template file (e.g. single-question.php).

<?php /* Template name: Question Template */ ?>

<?php get_header(); ?>

<div id="primary">
  <main id="main" class="site-main" role="main">

    <?php while (have_posts()): the_post(); ?>

      <article id="post-<?php the_ID(); ?>" <?php post_class(); ?>>
        <header class="entry-header">
          <h1 class="entry-title"><?php the_title(); ?></h1>
        </header>

        <div class="entry-content">
          <?php the_content(); ?>
        </div>

        <?php $answers = get_post_meta(get_the_ID(), 'answers', true); ?>
        <?php if (!empty($answers)): ?>
          <section class="answers">
            <h2 id="Answers">Answers</h2>
            <ul>
              <?php foreach ($answers as $answer): ?>
                <li><?php echo $answer; ?></li>
              <?php endforeach; ?>
            </ul>            
          </section>
        <?php endif; ?>
      </article>

    <?php endwhile; ?>

  </main>
</div>

<?php get_sidebar(); ?>
<?php get_footer(); ?>
Copy after login

Step 4: Create Q&A submission and display form
We need to create a front-end form through which users can submit questions and answers and save them to the database. We then need to display these questions and answers in the template.

function question_form_shortcode() {
  ob_start(); ?>

  <form id="question-form" method="post">
    <label for="question-title">Question Title</label>
    <input type="text" id="question-title" name="question-title" required>

    <label for="question-content">Question Content</label>
    <textarea id="question-content" name="question-content" required></textarea>

    <label for="answer-content">Your Answer</label>
    <textarea id="answer-content" name="answer-content" required></textarea>

    <input type="submit" value="Submit">
  </form>

  <?php return ob_get_clean();
}

add_shortcode('question_form', 'question_form_shortcode');

function save_question_and_answer() {
  if (isset($_POST['question-title']) && isset($_POST['question-content']) && isset($_POST['answer-content'])) {
    $question_title = sanitize_text_field($_POST['question-title']);
    $question_content = wp_kses_post($_POST['question-content']);
    $answer_content = wp_kses_post($_POST['answer-content']);

    $question_id = wp_insert_post(array(
      'post_title' => $question_title,
      'post_content' => $question_content,
      'post_type' => 'question',
      'post_status' => 'publish'
    ));

    $answers = get_post_meta($question_id, 'answers', true);
    $answers[] = $answer_content;
    update_post_meta($question_id, 'answers', $answers);
  }
}

add_action('init', 'save_question_and_answer');
Copy after login

Conclusion:
Through the guidance of this article, you can develop a WordPress plug-in that automatically generates a question and answer system. This plug-in can help you easily create a Q&A platform to increase interactivity and attraction. You can add additional features and customize styles to suit your users and website.

Which AI programmer is the best? Explore the potential of Devin, Tongyi Lingma and SWE-agent Which AI programmer is the best? Explore the potential of Devin, Tongyi Lingma and SWE-agent Apr 07, 2024 am 09:10 AM

On March 3, 2022, less than a month after the birth of the world's first AI programmer Devin, the NLP team of Princeton University developed an open source AI programmer SWE-agent. It leverages the GPT-4 model to automatically resolve issues in GitHub repositories. SWE-agent's performance on the SWE-bench test set is similar to Devin, taking an average of 93 seconds and solving 12.29% of the problems. By interacting with a dedicated terminal, SWE-agent can open and search file contents, use automatic syntax checking, edit specific lines, and write and execute tests. (Note: The above content is a slight adjustment of the original content, but the key information in the original text is retained and does not exceed the specified word limit.) SWE-A
