Display notices to the user - El Forum - 01-14-2010

I've got a feeling I'm missing something really obvious here but I'll ask anyway.
I've made a controller that lets people edit staff members in the system.
Code:
function edit_process(){
$this->load->library('form_validation');
$this->form_validation->set_rules('first_name', 'First Name', 'trim|required');
$this->form_validation->set_rules('second_name', 'Second Name', 'trim|required');
$this->form_validation->set_rules('email', 'Email Address', 'trim|required|valid_email');
$this->form_validation->set_rules('staff_id', 'Staff ID ', 'trim|required|integer');
if($this->form_validation->run() == FALSE){
//Show form & error
}else{
//Update staff
redirect('admin/staff/');
}
}If it all goes through successfully the user is redirected to admin/staff. How can I tell this page to display some sort of notification to say the user was updated?

Look for the section titled "Flashdata".

Ah, I only read that the other day. I knew it was a stupid question!

I have another question on the code above so I thought I'd ask here rather than create a new thread.
My URL for editing a user looks like mysite.com/admin/staff/edit/1 where the 1 is the ID of the user. If the form validation fails I want to show the form again with the validation error but I can't load the edit view again because I need the ID in the URL and if I redirect it doesn't show the error, would I use flashdata for this aswell or is there a better way?

you could do this
Code:
//in the view
<?php echo form_open($url); ?>
.
.
.
//view code
//in the controller
public function edit($id){
$data['url'] = 'staff/edit/' . $id;
.
.
.
$this->load->view('view_file', $data);Display notices to the user - El Forum - 01-15-2010

Or just have your form submit to the current page, and perform all of the editing on that page so that when validation fails you're still on /admin/staff/edit/1

flaky. I'm not sure what you mean :red:
noctrum, do you mean do an if to see if any form info has been sent in the controller, if it has process the form, if it hasn't show the form?

Hope this makes it clear what I'm trying to say, by using one single method I can do 2 things, insert and update.
Example
Code:
<?php
//Controller
class User extends Controller{
public function __construct(){
parent::__construct();
//load helpers
$this->load->helper('form');
//load models
$this->load->model('user_model');
}
public function index(){
//code that renders some view
}
public function save($user_id=null){
if($user_id != null && (int)$user_id){
if($this->input->post('user_ok')){
$data['user_id'] = $user_id;
$data['user_name'] = $this->input->post('user_name');
redirect('to some url');
}
$data['url'] = "user/save/" . $user_id;
$data['button_name'] = "Update";
$user = $this->user_model->get(array('user_id' => $user_id));
$user = $user[0];
$data['user_name'] = $user['user_name'];
$this->load->view('user_view', $data);
}
else{
if($this->input->post('user_ok')){
$user['user_name'] = $this->input->post('user_name');
$this->user_model->save($data);
redirect('to some url');
}
$data['user_name'] = "";
$data['url'] = "user/save";
$data['button_name'] = "Add";
$this->load->view('user_view', $data);
}
}
}
//Model
class User_model extends Model{
public function __construct(){
parent::__construct();
}
public function save($data){
if(isset($data['user_id'])){
$this->db->where('user_id', $data['user_id']);
$this->db->update('user', $data);
}
else{
$this->db->insert('user', $data);
}
}
public function get($data){
//it is best if I would select the fields I need, since it's only an example I won't go to that extent
if(isset($data['user_id']))
$this->db->where('user_id', $data['user_id']);
return $this->db->get('user')->result_array();
}
}
?>
//View
<div>
<?php echo form_open($url); ?>
<?php echo form_label('User'); ?>
<?php echo form_input('user_name', $user_name); ?>
<br/>
<?php echo form_submit('user_ok', $button_name); ?>
<?php echo form_close();
