form validation

[eluser]Ngulo[/eluser]
hi everyone i'm using these code to do the user registration without 2 distinct views ,but to do all in the same view(Home_view):

controller:

Code:

class Home extends Controller
{
    
    
    function index()
    {
      $this->load->helper(array('form','url'));
      $this->load->library('Validation');
      $rules['username']= "required|min_length[5]|max_length[12]";
      $rules['password']= "required|matches[confpassword]";
      $rules['confpassword']= "required";
      $rules['email'] = "required|valid_email";

      $this->validation->set_rules($rules);
      $fields['username']    = 'Username';
    $fields['password']    = 'Password';
    $fields['confpassword']    = 'Password Confirmation';
    $fields['email']    = 'Email Address';
        $this->validation->set_fields($fields);
        if($this->validation->run() == FALSE && isset($fields) )
        {$this->load->view('Home_view');}
        else{
            $data['messaggio_conferma']="registration ok";
            $this->load->view('Home_view',$data);

        }
    
    
    }
}

and home_view:

Code:

<?php echo form_open('home');?>
        Username
        <input type="text" name="username"><br>
        <?php echo $this->validation->username_error; ?>

            
        Password
        <input type="password" name="password"><br>
        
            <?php echo $this->validation->password_error; ?>
        Password Conferma
        <input type="password" name="confpassword"><br>
        <?php echo $this->validation->confpassword_error; ?>
            
        Email
        <input type="text" name="email"><br>

        
           <?php echo $this->validation->email_error; ?>

        <input type="submit" name="login" value="login"><br>
         <?php  if($this->validation->run() == TRUE){echo $messaggio_conferma;}?>

        </form>

it works really great

is not definitive code i have to upgrade and i have some questions about it

why does form_validation library doesn't works as the validation one? i can't use that

again, i would like to know how to set my personal error_messages's text for any error input name?

any suggest for my code? do you know a better way to do the registration in the same view page?

thanks to all

Not sure if this helps but since you said you need to upgrade and since forms are made a lot easier by this library, maybe you want to take a look at this excellent library that helps with forms here:

thanks a lot but for now i'm able only to say hello world in CI so i have to understand the framework's basics , later i will try new features

but now i'm still trying to configure my own error_messages on each input

how can i do to have my own messages displaying on each name error(username_error,password_error,etc ...)?

joking, maybe :
$this->validation->username_error('hello this is username error');??




thanks again

Any reason you're using validation instead of form_validation? validation is deprecated, and shouldn't be used. Either way, you can use set_message().

http://ellislab.com/codeigniter/user-gui...tingerrors

Code:

$this->form_validation->set_message('username', 'This is my username error');

hi noctrum , i was saying before that if i use this same code , loading form_validation instead of validation library's ,the apps doesn't works :O

i don't know why ,maybe when i make the changes to load the other library i forget something important ,i really don't know :O

anyway thanks a lot for the example to change form errors ,was all i need to know
