Question

如果我正在渲染添加表单或只是视图，我想从控制器检查。我想做这样的事情..

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());
    }       
}

除非我使用iframe，否则这样做会很有效，如果网址没有变化，这不会有效：P

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

这将获得它所处的状态。

        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，“list”将用于取消按钮，“success”适用于添加屏幕或编辑屏幕上的保存和更新按钮。
