检查杂货残渣状态

Question

我想要检查从控制器，如果我是呈现一个添加表单或只是一个视图。我想做这样的事。

public function clients()
{
    try{

        if ($_SERVER["REQUEST_URI"] == "/data/clients")
        {
            $data['client'] = $this->db->query("select * from clients");
            $this->load->view('cview/client',$data);
        }
        else 
        {

            $crud = new grocery_CRUD();

            //$crud->set_theme('datatables');
            $crud->set_table('clients');
            $crud->set_subject('Clients');
            crud->required_fields('city');
            //$crud->columns('city','country','phone','addressLine1','postalCode');

            $output = $crud->render();

            $this->load->view('/crud/users',$output);
        }
    }catch(Exception $e){
        show_error($e->getMessage().' --- '. $e->getTraceAsString());
    }       
}

这会很好，除非我正在使用Iframe，如果url不改变，它就不能工作:P

Answer 1

$state = $this->grocery_crud->getState();

这将得到它所处的状态。

        if (($state == "list" || $state == "success"))  
        {

            $data['client'] = $this->db->query("select * from clients");
            $this->load->view('cview/client',$data);
        }
        else 
        {

            $crud = new grocery_CRUD();

            //$crud->set_theme('datatables');
            $crud->set_table('clients');
            $crud->set_subject('Clients');
            $crud->required_fields('city','phone');


            //$crud->columns('city','country','phone','addressLine1','postalCode');

            $output = $crud->render();

            $this->load->view('/crud/users',$output);
        }

在上面的示例中，“列表”将在“取消”按钮上工作，而“成功”则在“添加”屏幕或编辑屏幕上的“保存和更新”按钮上工作。
