I have the followin form class:
<code>
<?php class loginForm extends sfForm { private function _setValidators() { $this->oValGebruikersnaam = new sfValidatorAnd( array( new sfValidatorString( array('min_length' => 3, 'max_length' => 50), array('min_length' => 'The username should be at least three characters long', 'max_length' => 'The username should be fifty characters long at most', ) ), new sfValidatorCallback( array( 'callback' => array('myLoginValidator', 'execute'), 'arguments' => array() ), array('invalid' => 'This username/password combination is unknown') ), ), array('required' => TRUE), array('required' => 'The username is mandatory') ); $this->oValWachtwoord = new sfValidatorString( array('required' => TRUE), array('required' => 'The password is mandatory') ); $this->oValReferrer = new sfValidatorString(array('required' => FALSE)); } private function _setWidgets() { $this->oWidGebruikersnaam = new sfWidgetFormInput(array(), array('id' => 'gebruikersnaam', 'size' => 25)); $this->oWidWachtwoord = new sfWidgetFormInputPassword(array(), array('id' => 'wachtwoord', 'size' => 10)); $this->oWidReferrer = new sfWidgetFormInputHidden(array(), array('id' => 'referrer')); } public function configure() { $this->_setValidators(); $this->_setWidgets(); $this->setValidators(array( 'gebruikersnaam' => $this->oValGebruikersnaam, 'wachtwoord' => $this->oValWachtwoord, 'referrer' => $this->oValReferrer, ) ); $this->setWidgets(array( 'gebruikersnaam' => $this->oWidGebruikersnaam, 'wachtwoord' => $this->oWidWachtwoord, 'referrer' => $this->oWidReferrer, ) ); $oDecorator = new sfWidgetFormSchemaFormatterDiv($this->getWidgetSchema()); $this->getWidgetSchema()->addFormFormatter('div', $oDecorator); $this->getWidgetSchema()->setFormFormatterName('div'); } /** * Bind override */ public function bind(array $taintedValues = null, array $taintedFiles = array()) { $request = sfContext::getInstance()->getRequest(); if ($request->hasParameter(self::$CSRFFieldName)) { $taintedValues[self::$CSRFFieldName] = $request->getParameter(self::$CSRFFieldName); } parent::bind($taintedValues, $taintedFiles); } } ?>

Thanks to Jordi Backx.

And the following custom myLoginValidator
<code>
<?php class myLoginValidator { /** * execute validator * * @param sfValidatorBase Validator instance that calls this method * @param string Value of field that sfValidatorCallback checks * @param array Arguments for correct working * * @return value field when OK. Nothing if error (sfValidatorError exception) */ public static function execute ($oValidator, $sValue, $aArguments) { $req = sfContext::getInstance()->getRequest(); $gebruikersnaam = $req->getParameter('gebruikersnaam'); $wachtwoord = $req->getParameter('wachtwoord'); $c = new Criteria(); $c->add(UserPeer::USERNAME, $gebruikersnaam); $user = UserPeer::doSelectOne($c); if($user){ if(sha1($user->getSalt().$wachtwoord) == $user->getSha1Password()){ //Login Ok. if($user->getActivated() === false){ throw new sfValidatorError($oValidator, 'inactive'); // Account inactive } else { return $sValue; // Account active. } } } // Throw exception when not OK throw new sfValidatorError($oValidator, 'invalid'); } } ?>

</code>

I want throw new sfValidatorError($oValidator, 'inactive'); to produce an error on my form, where the complete message can be stored in the loginForm.class.php. In that case, everything related to maintenance of the form is in one place.

And a second question, i want the $user object to be available in my controller. Because i use a function $this->getUser()->signIn($user); to store the users name, id and some other stuff in the user's session. How can i access that object in my controller?

A third question:
<code>
<?php $req = sfContext::getInstance()->getRequest(); $gebruikersnaam = $req->getParameter('gebruikersnaam'); $wachtwoord = $req->getParameter('wachtwoord'); ?>

</code>
is there an easier way of accessing the form posted fields (they are available in the oValidator right?

Ok, if found the answer to one of my questions. And partially to the others.
<code>
<?php $gebruikersnaam = $sValue; $wachtwoord = sfContext::getInstance()->getRequest()->getParameter('wachtwoord'); ?>

</code>

the gebruikersnaam is ofcourse the $sValue (since that is the form field on which the validator is placed). The password (wachtwoord in dutch) is the password which i need to get from the Request object. Is there another way for this?

<code>
<?php if($user){ if(sha1($user->getSalt().$wachtwoord) == $user->getSha1Password()){ //Login Ok. if($user->getActivated() === false){ throw new sfValidatorError($oValidator, 'inactive'); // Account inactive } else { return $user; // Account active. } } } ?>

</code>

Instead of returning the $sValue after successful validation, i return my $user object. Then in the controller i use:
<code>
<?php $aValues = $form->getValues(); $this->getUser()->signIn($aValues['gebruikersnaam']); ?>

</code>

the $aValues['gebruikersnaam'] should normally contain the form field value, but in my case it contains the entire user object which i can now use to set my user's sessions vars.

So, outstanding question is: custom error messages for the sfValidatorCallBack.

Here is how I did it:

<code>
<?php new sfValidatorCallback(array('callback' => array('passwordValidator', 'execute'), 'arguments' => array() ), array('invalid' => 'The two passwords you have entered do not match.') ?>
