Check grocery crud state - codeigniter

Question

I want to check the from the controller if I am rendering an add form or just a view. I want to do something like this..
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());
}
}
This would work well except I'm using an Iframe and this doesn't work if the url doesn't change :P

Answer 1

$state = $this->grocery_crud->getState();
this will get the what state it is in.
if (($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);
}
In this example above "list" will work on cancel button and "success" works on save and update button on the add screen or edit screen.
