Interesting approach, thanks for the reply! I'm currently going a different route. I'm setting all the "universal" fields in the standard datamapper fashion via $validation. Then, I've setup the constructor of my datamapper model to accept a single $form_type parameter. Based on that parameter, I know what additional fields should be validated.
Code:
class User extends DataMapper {
//Note: These are default validation rules. Additional rules are set based on the form type
//passed into the constructor.
var $validation = array(
array('field' => 'prefix', 'label' => 'Prefix', 'rules' => array('required', 'trim', 'max_length' => 10)),
array('field' => 'first_name', 'label' => 'First Name', 'rules' => array('required', 'trim', 'max_length' => 200)),
array('field' => 'last_name', 'label' => 'Last Name', 'rules' => array('required', 'trim', 'max_length' => 200)),
array('field' => 'account_id', 'label' => 'Account ID', 'rules' => array('integer', 'max_length' => 6)),
array('field' => 'email', 'label' => 'Email Address', 'rules' => array('trim', 'unique', 'valid_email')),
array('field' => 'company', 'label' => 'Company', 'rules' => array('required', 'trim', 'max_length' => 200)),
array('field' => 'job_title', 'label' => 'Job Title', 'rules' => array('required', 'trim', 'max_length' => 200))
);
/**
* Constructor
* @param string form_type - Type of form being processed.
*/
function __construct($form_type = null) {
$this->set_custom_validation($form_type);
parent::__construct();
}
/**
* Sets custom validation fields based on the form_type passed.
* Useful so fields that are only required/used on certain forms
* aren't required on every form dealing with user data.
* NOTE: This doesn't overwrite the default validation
* set in the $validation property above, it merely adds
* addtional fields to validate.
* @return
*/
function set_custom_validation($form_type) {
switch ($form_type) {
case 'register':
$this->validation[] = array('field' => 'password', 'label' => 'Password', 'rules' => array('required', 'trim', 'min_length' => 6, 'max_length' => 40, 'hash'));
break;
case 'password_reset':
$this->validation[] = array('field' => 'password_reset_token', 'label' => 'Password Reset Token', 'rules' => array('max_length' => 32));
break;
}
}
So as you can see, the password is only required on the registration form. And the password reset token is only processed on the password reset page.
I'm pretty happy with this setup but also considered simply passing additional validation fields directly to the constructor rather than passing a form type.
