This module is an add-on to the FAQ module that allows users with the 'ask question' permission to create a question which will be queued for an 'expert' to answer.

Code

function faq_ask_a_question_blockform() {

  // Include page handler for node_add()
  module_load_include('inc', 'node', 'node.pages');

  // If user is allowed to create a faq content type
  if (node_access('create', 'faq')) {

    // Fool the hook_form_alter function to think we're in an faq-ask page
    $saved_get = '';
    if (isset($_GET['ask'])) {
      $saved_get = $_GET['ask'];
    }
    $_GET['ask'] = '1';
    $_GET['block'] = 'TRUE';

    // Note title before rendering of form.
    $title = drupal_get_title();

    // Create the form
    $form = node_add('faq');

    // Restore title, which will have been overridden.
    drupal_set_title($title, PASS_THROUGH);

    // Issue #1811600 by TBarina: Giving permission to Ask a Question causes all node titles to display &;#039; instead of apostrophe.
    // Adding param const PASS_THROUGH tp the drupal_set_title() function to avoid check_plain()
    // Restore the $_GET['ask'] variable status
    if ($saved_get != '') {
      $_GET['ask'] = $saved_get;
    }
    else {
      unset($_GET['ask']);
    }
    unset($_GET['block']);
    return $form;
  }
  else {
    return '';
  }
