Sometimes our restaurant critics will want to remove their old drafts, and reviews of restaurants that have closed. Once again, adding a function to the RestaurantsController class in /administrator/components/com_restaurants/restaurants.php will power the Delete button in the toolbar seen in the all view. Open that file and add the following remove() function:

function remove()
{
JRequest::checkToken() or jexit( 'Invalid Token' );
global $option;
$cid = JRequest::getVar('cid', array(0));
$row =& JTable::getInstance('review', 'Table');
foreach ($cid as $id)
{
$id = (int) $id;
if (!$row->delete($id))
{
JError::raiseError(500, $row->getError() );
}
}
$s = '';
if (count($cid) > 1)
{
$s = 's';
}
$this->setRedirect('index.php?option=' . $option, 'Review' . $s . ' deleted.');
}

Notice that although the name of the JToolBarHelper member function that generates the Delete button is deleteList(), the button is passing in the task remove when it is clicked. Because...
