Handle Language / Validation Mode in the Form Validation Helper

[eluser]dsentker[/eluser]
Hey Guys,

First: sorry for my bad english, i'm from germany and i hope my problem is understandable.

I am new at CodeIgniter cause I love the MVC Usage since i got unsolved (logical) problems with my "normal PHP knowledge". Be that as it may, here are my two little questions:

1: I'm interested in the handy Validation Helper - Sadly, i don't know how to handle different languages for that helper. I want to change the Error Messages (e.g. "The Password field is required!") into German - but how i can do that?

2: Validation Helper, too: I have the possibility to check, if a field matches another field. That's good - but what can i do if a field don't have to match with another field? In my case, the Password should NOT be the Username. In "standard PHP", i would use this:

Code:

$_POST['pass'] == $_POST['username'] ? echo 'Choose another password!' : echo 'success!';

Any possibility to use the Validation Helper for my wish?

Thanks for your Help!

Translating Field Names

If you would like to store the "human" name you passed to the set_rules() function in a language file, and therefore make the name able to be translated, here's how:

First, prefix your "human" name with lang:, as in this example:

Code:

$this->form_validation->set_rules('first_name', 'lang:first_name', 'required');

Then, store the name in one of your language file arrays (without the prefix):

Code:

$lang['first_name'] = 'First Name';

Note: If you store your array item in a language file that is not loaded automatically by CI, you'll need to remember to load it in your controller using:

Code:

$this->lang->load('file_name');

See the Language Class page for more info regarding language files.

use callback functions
example

Code:

$this->form_validation->set_rules('password', 'required|callback_check_with_username');
if ($this->form_validation->run() == TRUE){
.
.
.

public function check_with_username($password){
    $this->form_validation->set_message('check_with_username', 'Choose another password');
    
    if($password == $this->input->post('username'))
        return false;
    else
        return true;
}

I think i was misunderstood. How can i change the Error Message, e.g. "The Password field is required" into "Es wird ein Passwort benötigt!" (German Version)? Do i have to read the Language class again? Sorry for my "noob" Questions...

Good Idea, thanks for that. Where i can learn more about callback functions and -triggers?
