I am building a custom login process which follow these steps:

  1. Request user email (submits to custom controller)
  2. Check if user has an account
  3. If they have an account, show a form requesting their password. Or if they don't have an account then send them to the registration form.

The forms exist as front end templates.

I can accomplish all these steps but when the user is redirected I need to make the email address that they entered available to the template.

My custom controller calls a service to check if the user exists which is all fine. And I can redirect the user to the appropriate URL. But I can't figure out how to retain the email address they entered.

Currently I've just done it by appending the email as a query string but this is undesirable for a couple of reasons.

The controller currently looks like this although I feel this is totally the wrong way to be doing things.

public function actionEmailCheck() {

        $email = Craft::$app->request->post('loginName');

        $result = MyModule::$instance->order->checkEmail($email);

        if($result) {
            $redirect = '/login/password?email='.$email;
        } else {
            $redirect = '/register?email='.$email;


I feel like I should be able to set some template variables and load the appropriate template but that doesn't seem to work.

I also tried this

if($result) {
            $this->renderTemplate('/login/password', array('email'=>$email));
        } else {
            $this->renderTemplate('/register', array('email'=>$email));

But while the template was displayed, I couldn't access the value for 'email'.

So how should I approach this?

You could do this by saving the email address to a custom session variable like this in your controller:

Craft::$app->getSession()->set('email', $email);

This should then be available in your template using:

{{ set email = craft.app.session.get('email') }}
  • I did try that but for some reason it wasn't working. I'll give it another go.

  • Well it worked that time with a minor change to Craft::$app->getSession()->set('email',$email). Would still like to know if there's a way to do it without setting the session variable.

  • The only way to do it would be either to set a session variable or to pass GET variables to the redirect destination Commented Oct 15, 2019 at 13:28
