Symfony: prevent form field from being saved - forms

Question

I have a form to change email, EmailChangeForm which extends the guard user form, sfGuardUserForm and uses two columns: email_address and password.
I want the form to check if the password is correct and if so, change the email to the new one.
My problem is that the form also saves the password field to the user object.
I know that since the password is checked, it cannot be changed in theory, but I still don't like it being re-saved with the new value from the form, so is there a way to make the form only save the email_address field?

Answer 1

I would suggest a sceleton like this :
class emailForm extends sfFrom {
public function configure(){
$this->widgetSchema['email'] = new sfWidgetFormInputText();
$this->widgetSchema['password'] = new sfWidgetFormInputPassword();
$this->validatorSchema['password'] = new myValidatorPassword();
}
}
class myValidatorPassword extends sfValidatorBase{
protected function doClean($value)
{
$clean = (string) $value;
// current user
$sf_guard_user = sfContext::getInstance()->getUser()->getGuardUser();
if($sf_guard_user)
{
// password is ok?
if ($sf_guard_user->checkPassword($value))
{
return $clean;
}
}
// Throw error
throw new sfValidatorError($this, 'invalid', array('value' => $value));
}
}
So in your action you can easily save the new password :
/***** snip *****/
if($this->form->isValid()){
// set and save new password to current user
$user = $this->getUser()->getGuardUser();
$user->setPassword($formValues["password"]);
$user->save();
/***** snip *****/
Of course this is a basic approach, improvements are always welcome :-)

First make sure you're using the useFields function in your EmailChangeForm class. With that you can define which fields you want to edit with your form (this is better than unset because if you add more fields you dont have to worry with useFields). Example:
$this->useFields(array(
'email'
));
DO NOT INCLUDE THE PASSWORD!
Second: In your template put an extra input field for your password with the same name schema (updatemail[password]).
Third: In your action before the $form->isValid method you add the following:
$params = $request->getParameter($form->getName();
unset($params['password'];
$form->bind($params), $request->getFiles($form->getName()));
if($form->isValid()) {...}

Answer 3

create the new form (editUserForm for example) that extend the base form and then unset the password by this code
class editUserForm extend baseForm{
public function configure(){
unset($this['password']);
}
}
all the name above is an example you must change it to your name.

Answer 4

I'm assuming there is only one field in EmailChangeForm, and that EmailChangeForm extends SfUserForm...
To eliminate all the fields except the email field add this to the configure method:
$this->useFields(array('email'));
