Question

i am developing an application where i need some suggestions. Here is the detail of the problem.

public function form()
{
    $this->load->helper('inflector');
    $id =   $this->uri->segment(3,0); 

    if($data = $this->input->post()){
        $result =   $this->form_validation->run();
        if($result){
            if($id > 0){
              // here update code
            }else{
                $this->mymodel->insert($data);
                $this->session->set_flashdata('message','The page has been added successfully.');
                $this->redirect =   "mycontroller/index";
                $this->view     =   FALSE;
            }
        }else{
            //$this->call_post($data);
            $this->session->set_flashdata('message','The Red fields are required');
            $this->view     =   FALSE;
            $this->redirect =   "mycontroller/form/$id";
        }
    }else{

        $row    =   $this->mymodel->fetch_row($id);
        $this->data[]=  $row;
    }
}


public function _remap($method, $parameters)
{
    if (method_exists($this, $method))
    {
        $return =   call_user_func_array(array($this, $method),$parameters);
    }else{
        show_404();
    }

    if(strlen($this->view) > 0)
    {
        $this->template->build('default',array());

    }else{
        redirect($this->redirect);
    }   
}   

Here you can see how i am trying to reload the page on failed validation.
Now the problem is that i have to display the flash data on the view form which is only available after redirect and i need to display the validation errors to which are not being displayed on redirect due to the loss of post variable. If i dont use redirect then cant display flashdata but only validation errors. I want both of the functionalities togather. I have tried even creating POSt again like this

public function call_post($data)
{
    foreach($data as $key => $row){
        $_POST[$key]    =   $row;
    }   
}

Which i commented out in the formmethod.How can i achieve this.

Here’s a thought.

I think you can add the validation error messages into the flash data. Something like this should work:

$this->session->set_flashdata(‘validation_error_messages’,validation_errors());

Notice the call to the validation_errors function. This is a bit unconventional, but I think it should work. Just make sure that the code are executed after the statement $this->form_validation->run(); to make sure the validation error messages are produced by the Form Validation library.
