为Joomla3.2自定义组件创建一个Cancel按钮

Question

我正在尝试构建一个Joomla3.2自定义组件，并且很难让取消按钮(管理部分)工作。我已经添加了按钮，但是当我单击它时，我得到了错误：

0无效控制器: name='helloworld'，format='‘

这是为组件'helloworld‘和视图’再见‘。有人能看看我的文件并告诉我如何使“取消”按钮工作吗？我只希望它关闭当前页面并返回到默认组件页。

谢谢你的帮助。

Answer 1

将HelloWorldViewGoodbye更改为GoodbyeViewGoodbye和相同的。

Answer 2

取决于要实现添加控制器的操作。

    public function cancel($key = null) {
    JSession::checkToken() or jexit(JText::_('JINVALID_TOKEN'));

    $this->setRedirect(JRoute::_('index.php?option='.$this->option.'&view=name_of the_view' , false));
    return true;
}

在view.html中向按钮添加条件

    if (condition when to use button)
        {
        JToolbarHelper::cancel('your_controller_name.cancel');
        }
    else
        {
        JToolbarHelper::cancel('your_controller_name', 'JTOOLBAR_CLOSE');
        }
