Question

I am trying to submit a EDIT form which edits Users Academics Details,
These Details have unique id in DB and my Code in Short Looks like below :

class edit extends ci_controller
{

function user_academics($id = NULL)
    {
        if(isset($id) == FALSE)     //if link is ./edit/user_academics
        {
            $id = NULL;
            $link = site_url('profile');
            show_error("Invalid Page Request! <a href='$link' Go to Profile </a>");
        }

        $user_id = $this->session->userdata('user_id');        
        $data['fill'] = $this->edit_model->get_user_academics($id);

        if($user_id != $data['fill']['user_id'])    // check if logged in user is accessing his record or others
        {
             $link = site_url('profile');
            show_error("This is an Invalid Request ! <a href='$link'>Go to Profile </a>");
        }
        else // actual work starts here
        {
            $this->session->set_flashdata('ua_id',$id); // update_academics will get this data

            $this->load->view('edit/edit_3_view',$data);

        }
    }

 function update_academics()
    {
        $ua_id =  $this->session->flashdata('ua_id');   // flash data used here .
        if( !$ua_id )
        {
            show_error('Sorry, This request is not valid!');

        }
      $academics = array( 
            // All post values
        );

        $this->edit_model->update_user_academics($academics,$ua_id);
        //print_r($academics);
        redirect('profile');

    }

}

Now the problem is
– If I open two different records to edit, then It will set only one Session Flash value.
– And No matter what I edit , the existing values of the last flash value gets updated.
Please Suggest me another way or Correct me if I am wrong in above code . Thanks

save that flashdata in array, like:

$myArr = array('value 1', 'value 1');
//set it
$this->session->set_flashdata('some_name', $myArr);

And in view:

$dataArrs = $this->session->flashdata('some_name');
//loop thru $dataArrs to show the flashdata
