Report abuse links

On Economist.com we use the VotingAPI for both comment recommends and abuse reports

We have a simple module that goes along side voting_api that handles whether it is a recommend or an abuse report.

Below is a sample piece of code that is the submit function for the form that appears on the page listed above when you report abuse.

function ec_vote_report_abuse_form_submit($form, &$form_state) {
  $cid = isset($form_state['values']['cid']) ? $form_state['values']['cid'] : NULL;
  $nid = isset($form_state['values']['nid']) ? $form_state['values']['nid'] : NULL;
  $ec_abuse_explanation = isset($form_state['values']['ec_abuse_explanation']) ? $form_state['values']['ec_abuse_explanation'] : NULL;
  $reason_key = isset($form_state['values']['ec_abuse_reason']) ? $form_state['values']['ec_abuse_reason'] : NULL;
  $ec_abuse_reason = isset($form_state['values']['abuse_reasons'][$reason_key]) ? $form_state['values' ['abuse_reasons'][$reason_key] : NULL;
  $result = ec_vote_insert_vote($cid, $ec_abuse_reason, $ec_abuse_explanation);
  $redirect_url = isset($nid) ? 'node/' . $nid . '/talk' : '/';
  $form_state['redirect'] = $redirect_url;
}

The code for recommending is quite similar although I think this function handles being called with a nid or a cid

function ec_vote_set_vote($content_type) {
  $params = ec_proxy_get_params();
  $votes[] = array(
    'content_type' => $content_type,
    'content_id' => !empty($params['dr_cid']) ? $params['dr_cid'] : $params['ec_nid'],
    'value_type' => 'points',
    'value' => 1,
    'ec_abuse_reason' => $params['ec_abuse_reason'],
    'ec_abuse_explanation' => $params['ec_abuse_explanation'],
  );
  $affected = votingapi_set_votes($votes);

  // For recommend-comments we need to know what to clear from the cache in CF
  // so return nid (or named_key for api).
  if (!empty($params['dr_cid'])) {
    $sql = 'SELECT n.nid, n.type, n.title FROM {comments} c, {node} n WHERE c.nid = n.nid AND c.cid = %d';
    $result = db_query($sql, $params['dr_cid']);
    while ($row = db_fetch_object($result)) {
      if ($row->type == 'api') {
        $key_to_clear = $row->title;
      }
      else {
        $key_to_clear = $row->nid;
      }
    }
    $affected['recommend-comment'][$params['dr_cid']]['key_to_clear'] = $key_to_clear;

    // Store the rendered comment in the cache.
    cache_clear_all('ec_comment_'. $params['dr_cid']);
  }
  $return = array(
    'content' => $affected[$content_type],
    'status' => 200,
  );
  return ec_json($return);
}

With these you just need to set up a bit of Ajax magic to call those callbacks.
