Convert Normal PHP form to CF7 Form

Resolved

(@rawahapool)

Hi, I have a form that is printing checkboxes, what I need is I need to map the options of a checkbox as the $post_title variable, that’s it,

so the output should be :

✓ post1

✓post2

✓post 3

etc

Here is my current code :

// Fetch published 'checklist' posts

function checklist_fetch_posts()

{

    $args = array(

        'post_type' => 'checklist',

        'post_status' => 'publish',

        'posts_per_page' => -1, // Retrieve all posts

    );

    $checklist_posts = new WP_Query($args);

    echo '<form method="post" action="process_form.php">';

    if ($checklist_posts->have_posts()) {

        while ($checklist_posts->have_posts()) {

            $checklist_posts->the_post();

            // Access post data here

            $post_title = get_the_title();

            // $post_content = get_the_content();

            // Output the post information as desired

            // echo '<h2>' . $post_title . '</h2>';

            echo '<label>

            <input type="checkbox" name="' . $post_title . '" value="' . $post_title . '">

            ' . $post_title . '

            </label><br>';

        }

        echo '<input type="submit" name="submit" value="Submit">';

        // Restore original post data

        wp_reset_postdata();

    } else {

        // No posts found

        echo 'No checklists found.';

    }

    echo '</form>';

}

Thanks,

let me know if any detail needed

Ok , so this code worked for me :

add_filter('wpcf7_form_elements', 'custom_wpcf7_form_elements');

function custom_wpcf7_form_elements($form)

{

  global $post;

  global $wpdb;

  if ($post && 'product' === $post->post_type) {

    $productID = $post->ID;

  }

  $selection_name = get_post_meta(

    $productID,

    'checklist_selection',

    true

  );

  $database_table_name = $wpdb->prefix . 'selected_posts';

  // Prepare the query with proper variable escaping

  $selected_row = $wpdb->get_row(

    $wpdb->prepare(

      "SELECT * FROM $database_table_name WHERE selection_name = %s LIMIT 1",

      $selection_name

    )

  );

  if ($selected_row) {

    $chosen_items = $selected_row->selected_post_id;

    $chosen_ids_array = explode(',', $chosen_items); // Convert the string to an array of IDs

    $checklist_posts = array(

      'post_type' => 'checklist',

      'post_status' => 'publish',

      'posts_per_page' => -1, // Retrieve all posts

      'post__in' => $chosen_ids_array, // Filter by the chosen IDs

    );

    $checklist_query = new WP_Query($checklist_posts);

    $options = array();

    if ($checklist_query->have_posts()) {

      while ($checklist_query->have_posts()) {

        $checklist_query->the_post();

        $title = get_the_title();

        $options[] = $title;

      }

    }

    // Restore the global post data

    wp_reset_postdata();

  }

  // Create a new DOMDocument object

  $dom = new DOMDocument();

  $dom->loadHTML($form);

  // Find the specific HTML code block using XPath

  $xpath = new DOMXPath($dom);

  $elements = $xpath->query('//span[@class="wpcf7-list-item first last"]/label/span[text()="option 1"]/parent::*/parent::*');

  // Remove the found elements

  foreach ($elements as $element) {

    $element->parentNode->removeChild($element);

  }

  // Get the updated form HTML code

  $form = $dom->saveHTML();

  $itemToReplace = '<span class="wpcf7-form-control-wrap" data-name="checkbox-591"><span class="wpcf7-form-control wpcf7-checkbox" id="hidden-item"></span></span>';

  $form = str_replace($itemToReplace, $itemToReplace, $form);

  foreach ($options as $option) {

    $itemToConcatenate = '<span class="wpcf7-list-item"><input type="checkbox" name="checkbox-591[]" value="' . $option . '"><label><span class="wpcf7-list-item-label">' . $option . '</span></label></span><br>';

    $form = str_replace($itemToReplace, $itemToReplace . $itemToConcatenate, $form);

  }

  return $form;

}
