Encrypt data when saving into database.

Hello All,

I have a tabel with data in it.
i have created a form that store's the data, its working fine.

now i want to encrypt the saved data only on 1 textfield.
is this possible and how can i do it?

Use a HOOK before values are saved and use the class Encryption in
system/modules/core/library/Contao/Encryption.php
e.g.

PHP Code:

---

\Encryption::encrypt($myVar) 


---

Thanks for the replay,

I have made a hook and add it to my config file,
When i create a autoload (backend autoload creator) the class is not be saved in my autoload.

The hook in config/config.php :

Code:

---

$GLOBALS['TL_HOOKS']['prepareFormData'][] = array('encrypt_form_data', 'MyEncryptFormData');

---

and the class in classes/encrypt_form_data.php is :

Code:

---

<?php if (!defined('TL_ROOT')) die('You can not access this file directly!');


class MyEncryptFormData
{

        public function EncryptFormData($arrSubmitted, $arrLabels, $objForm)
        {
                if (isset($arrSubmitted['dossier'])){
                        $arrSubmitted['dossier'] = Encryption::encrypt($arrSubmitted['dossier']);
                }

        }

}

When i add it in autoload.php See code below i get a error Cannot redeclare class

Code:

---

'encrypt_form_data'                          => 'system/modules/inbalans/classes/encrypt_form_data.php',

---

First build an extension with the extension creator from within back end. Then take a look at the config files. It should be self-explanatory.

Thanks, The problem is solved.

My class was a different name then the file so it wassend loading.
