$display_settings = array(
            'form' => array(
                'legend' => array(
                    'tITle' => $this->l( 'Display Settings' ),'icon' => 'icon-cogs'

                        'query' => array(
                            array(
                                'id' => 'show_header','name' => $this->l('show header'),'val' => '1','checked' => 'checked'
                            ),),'id' => 'id','name' => 'name'
                    )
                ),'submit' => array(
                    'title' => $this->l( 'Save Display Settings' ),'class' => 'button pull-right','name' => 'save-main-display-settings',)
            ),);

但是这个只显示了checkbow(未选中).我试图将val变成0,1.但它对我没有用.那么有人可以告诉我如何在帮助程序类中选中复选框.任何帮助或建议都将非常适合.谢谢
