Subject: How can I create a user login mechanism in symfony 1.4
Print | Individual message | Show original | Report this message | Find messages by this author

Hello everyone,

I want to create a login mechanism for users in my current project.

This is what I have done so far.

Created a function named executeLogin in the UsersActions class

class usersActions extends sfActions
{
    public function executeLogin(sfWebRequest $request)
    {
        $this->form = new UsersLoginForm();
        if($request->isMethod('post'))
        {

$this->form->bind($request->getParameter($this->form->getName()));
            if($this->form->isValid())
            {
                $loginSuccess = Doctrine_Query::create()
                ->select('u.email, u.password')
                ->from('users u')
                ->where('u.email = ? and u.password = ?',
array($request->getParameter('email'), $request->getParameter('password')))
                ->fetchArray();

                if($loginSuccess)
                {
                    $this->getUser()->setFlash('success', 'You have logged
in successfully.');
                    $this->redirect('users/index');
                }
                else
                {
                    $this->getUser()->setFlash('notice', 'Error while
logging in.');
                }
            }
        }
    }

}

The code in the form class is as follows:

class UsersLoginForm extends sfForm
{

    public function configure()
    {
        $this->setWidgets(array(
            'email' => new sfWidgetFormInput(),
            'password' => new sfWidgetFormInputPassword()
        ));

        $this->widgetSchema->setNameFormat('login[%s]');

        $this->setValidators(array(
            'email' => new sfValidatorEmail(array(
                'required' => true
            ), array(
                'required' => 'Please enter your email'
            )),
            'password' => new sfValidatorString(array(
                'min_length' => 2
            ), array(
                'min_length' => 'Minimum password length should be 2 chars
long.'
            ))
        ));

        $this->widgetSchema->setNameFormat('users[%s]');
        $this->errorSchema = new
sfValidatorErrorSchema($this->validatorSchema);
        parent::setup();
    }

}

and here is the loginSuccess.php file

<h2>Enter your email and password to login</h2>

<form action="<?php echo url_for('users/login') ?>" method="post">
    <?php
    echo $form;
    ?>
    <input type="submit" value="Save" id="btnSubmit" />
</form>

 When I submit the form nothing happens at all. Please help me correct this.

Thanks.

Why not just use the sfDoctrineGuardUser plugin ... works a treat ...

i've used the Login form to do the authentication/authorisation logic, if
the form doesnt pass validation - the user isnt logged in..

    public function configure()
    {
       ....

        // call the doLogin function...
        $this->validatorSchema->setPostValidator(new
sfValidatorCallback(array(
          'callback' => array($this, 'doLogin'),
        )));
    }

    // authentication
      public function doLogin(sfValidatorBase $validator, array $values)
    {
        if($values['email']!='') {
            // get the user
            $u = Doctrine_Core::getTable('User')
             ->createQuery('u')
             ->where('u.email = ?', $values['email'])
             ->limit(1);

            $dbUser = $u->execute()->getFirst();

            if(!$dbUser) {

                // invalid username - generic message
                $error = new sfValidatorError($validator, 'Error with
login'); // dont give too much info away
                // throw an error bound to the password field'
                throw new sfValidatorErrorSchema($validator, array('email'
=> $error));

            } else {

                $submittedPassword = $values['password'];
                $userObj = new User();
                $hashedPassword =
$userObj->hashPassword($submittedPassword);

                $found = false;

                if($hashedPassword == $dbUser->getPassword()) {

                    $found = true;
                }

                if(!$found) {
                    // invalid username - generic message
                    $error = new sfValidatorError($validator, 'Error with
login'); // dont give too much info away
                    // throw an error bound to the password field'
                    throw new sfValidatorErrorSchema($validator,
array('password' => $error));
                }
            }
        }
    }

then in my action i do the following:

  public function executeLoginRegister(sfWebRequest $request)
  {

    $this->form = new LoginForm();

    // posted the form?
    if ($request->isMethod('post') && $request->getParameter('user'))
    {
      // set the form values and validate the form
      $this->form->bind($request->getParameter('user'));

      if ($this->form->isValid())
      {
        // user is authenticated
      } else {
        // user failed authentication
      }
   }

hope that helps!

:)
thanks for your help. I appreciate it.

But I did it like this...

in the actions class 'login' function

public function executeLogin(sfWebRequest $request)
    {
        $this->form = new UsersLoginForm();
        if($request->isMethod('post'))
        {
            $this->form->bind($request->getParameter($this->form-

>getName()));

            if($this->form->isValid())
            {
                $userData = $this->form->getValues();
                $loginSuccess = Doctrine_Query::create()
                ->select('u.email, u.password')
                ->from('users u')
                ->where('u.email = ? and u.password = ?',
array($userData['email'], $userData['password']))
                ->fetchArray();

                if($loginSuccess)
                {
                    $this->getUser()->setAuthenticated(true);
                    $this->getUser()->addCredential('user');
                    $this->getUser()->setFlash('success', 'You have
logged in successfully.');
                    $this->redirect('users/index');
                }
                else
                {
                    $this->getUser()->setFlash('notice', 'Invalid
email or password. Please try again.');
                }
            }
        }
    }

and the above worked properly..

Your code says that you store passwords in plaintext. That's a very bad idea.

Yes I do, but it is only for now (as I have just started learning
symfony, I will learn that too, the symfony way).

Can you help me with this?
i.e.

What method or standard shall I use to handle password storage in
symfony?

Is it same like encrypting it with sha1() and then checking the whole
string.... sort of logic..?

Thanks

you shouldn't call   parent::setup(); in configure()

You already got two very good tips: one was a hint to use
sfDoctrineGuard, the other was a form class.

Justen Doherty sent the class, I recommend checking it, it's pretty
much what I'm using it a lot of projects - delegating login validation
to the form class, so the in action it's a simple `$form->isValid()`.

Manse sent the hint for the sfDoctrineGuardPlugin[1], I cannot
recommend it enough, it's the de-facto standard for user
authentication/authorization in the symfony 1 world. It's awesomely
written, so even if you do not end up using it, reading the code is
highly recommended.
