#Limit One Listing Per User

function one_listing_limit_registered_user($permission, $params)
{
  $listingPermissions = (S2Object::make('perm'))->__('listing');
 
  $auth = S2Object::make('auth');
 
  if ( $auth->id > 0 )
  {
    $Model = new S2Model();
 
    $query = sprintf('SELECT count(*) FROM %s WHERE %s = %d AND state = 1', EverywhereComContentModel::_LISTING_TABLE, EverywhereComContentModel::_LISTING_USER_ID, $auth->id);
 
    $count = $Model->query($query,'loadResult');
 
    if ( $count > 0 )
    {
      $listingPermissions->setMessage('You have reached the limit of one listing per user');
 
      return false;
    }
  }
 
  return $permission;
}
 
Clickfwd\Hook\Filter::add('can_create_listing', 'one_listing_limit_registered_user', 10);
