function discussthis_autocomplete in Discuss This! 7.2

Same name and namespace in other branches

1. 5 discussthis.module \discussthis_autocomplete()
2. 6 discussthis.autocomplete.inc \discussthis_autocomplete()
3. 7 discussthis.autocomplete.inc \discussthis_autocomplete()

Autocomplete a forum topic discussion title.

The function does not return if the auto-complete feature worked. Otherwise, it returns NULL.

NOTE : The previous version included a $tid parameter. It was not being used and it would not work properly if the user was creating a new node (i.e. you cannot select a forum, then a title, at least, not dynamically... and it was shown as being like that before.)

Parameters

$string The user string so far:

1 string reference to 'discussthis_autocomplete'

discussthis_menu in ./discussthis.module

Implements hook_menu().

File

./discussthis.autocomplete.inc, line 24

Function to compute the auto-complete string used in the discussion title.

Code

function discussthis_autocomplete($string = '') {

  // Anything yet?
  if (!$string) {
    echo drupal_json_encode(array());
    exit;
  }

  // Current user has the right to do that?!
  if (!user_access('access content')) {
    drupal_access_denied();
    return;
  }
  $result = db_select('node', 'n')
    ->fields('n', array(
    'nid',
    'title',
  ))
    ->condition('type', 'forum', '=')
    ->condition('title', db_like($string) . '%', 'LIKE')
    ->execute();
  $matches = array();
  while ($record = $result
    ->fetchAssoc()) {
    $matches[$record['nid']] = check_plain($record['title']) . ' [nid:' . $record['nid'] . ']';
  }
  echo drupal_json_encode($matches);
  exit;
}
