Rendering the button

To render the login button anywhere, you can use the loginButton.render() function of the component the plugin registers.

Note: All these options work for the continueButton as well.

{{ craft.vippsLogin.loginButton.render() | raw }}

The button defaults to large (250px) rectangle formed button. If the language is not given by any of the language functions below and the current site language is nb, nn, nb-NO or nn-NO, the plugin will use Norwegian buttons. If no language is given and the current site language is something other than Norwegian, English buttons will be used.

The button can be modified by adding functions between loginButton and render():

Function Description Example
en or english English text craft.vippsLogin.loginButton.en.render()
no or norwegian Norwegian text (Default) craft.vippsLogin.loginButton.no.render()
pill Pill shape craft.vippsLogin.loginButton.pill.render()
rect or rectangle Rectangle shape (Default) craft.vippsLogin.loginButton.rect.render()
small Small size, 210px craft.vippsLogin.loginButton.small.render()
large Large Size, 250px (Default) craft.vippsLogin.loginButton.large.render()
continue Change the login button to "Continue" craft.vippsLogin.loginButton.continue.render()
login Change the continue button to "Login" craft.vippsLogin.continueButton.login.render()
register Change the button to "Register" craft.vippsLogin.continueButton.register.render()

These functions can be combined:

{{ craft.vippsLogin.loginButton.en.pill.small.render() | raw }}

You can also add parameters to the <a> and <img> tag by providing a string in the render function: render(a, img)

Append the a tag:

{{ craft.vippsLogin.loginButton.render('rel="external"') | raw }}

Append the img tag:

{{ craft.vippsLogin.loginButton.render(null, 'title="Login with Vipps" class="btn"') | raw }}

Append to both:

{{ craft.vippsLogin.loginButton.render('rel="external"', 'title="Login with Vipps" class="btn"') | raw }}

ReturnURL

You can add a return URL by using the returnUrl() function. Or, you can manually add ?r=BASE64URL(yoururl) to the end of the button link, should you need to dynamically update with JavaScript.

Rendering your own button

You can also call the function craft.vippsLogin.getLoginUrl() or craft.vippsLogin.getContinueUrl() to just get the URL.

<a href="{{ craft.vippsLogin.getLoginUrl() }}">Log in with Vipps</a>
<a href="{{ craft.vippsLogin.getContinueUrl() }}">Continue with Vipps</a>

Getting user information from Vipps

As long as the user's Vipps token is not expired, you can access the user information with the session object.

{% if craft.vippsLogin.session %}
    <p>Hi, {{ craft.vippsLogin.session.getGivenName }}!</p>
{% else %}
    <p>Not logged in</p>
{% endif %}

Attributes of the Session object

Attribute Type Description
isExpired boolean Is the Vipps session valid
getExpiresIn integer How long til the Vipps session expires
getAddresses array Array of registered addresses
getEmail string User email
isEmailVerified boolean Is the email verified
getGivenName string Users given name
getFamilyName string Users family name
getName string Users full name
getPhoneNumber string Users phone number
getSid string Returns the Session ID
getSub string Unique ID for this user
getNnin string Returns the Norwegian National Identification Number
getBirthdate string Returns the users birthdate

Showing error messages

This plugin utilizes Craft::$app->session->setFlash() for outputting error messages.

To show these messages in your template you need to look at the documentation and implement something similar to this:

{% set messages = craft.app.session.getAllFLashes(true) %}
{% for key, message in messages %}
    <p class="{{ key }}">
        {{ message }}
    </p>
{% endfor %}
Type Description Message
danger Login failed in Vipps error_description from Vipps API
danger Login failed in Vipps without message 'Something went wrong while logging you in. Please try again, if the error persists contact the site administrator.'

Using the "Automatic Return" flow option

Before using this option, please read about the function and its security implications in Automatic return from Vipps app.

Changing the Password Verification template

When a user register/login with Vipps and an email that exists, they will be asked to confirm the password and the accounts will be linked.

If the setting under "Verification Template" under the "Log In with Vipps" tab is empty, our example template vendor/vippsas/vipps-login-craft/src/templates/verify.twig is used. To make your own, make a new twig file in your templates folder and update the setting.

If your template is located in templates/vipps/verify set the "Verification Template" option to vipps/verify. Use our example template to see the logic and forms that needs to be present.

Password verification and connecting to existing accounts

When a user attempts to sign up with an email that already exist they are redirected to a password verification page. When they confirm their password the existing account is linked to the Vipps account and the user can log in using Vipps.

The password verification template provided by the plugin is just an example and can be found in vendor/vippsas/src/templates/verify.twig. Use this template as a starting point for implementing your own design. Update the field in Settings -> Log In with Vipps -> Verification Template with the new template path.

Ex. if your template is templates/vipps/verification.twig the settings field should be vipps/verification.

Events

The plugin triggers different events based on the user actions. These can be used to inject logic.

Example code

use yii\base\Event;
use vippsas\login\events\LoggedInEvent;
use vippsas\login\VippsLogin;

...

Event::on(
    VippsLogin::class,
    VippsLogin::EVENT_USER_LOGGED_IN,
    function(LoggedInEvent $e) {
        // Implement your own logic here
        // using the $e variable to access 
        // User and Session classes
        die(var_dump([
            'message' => 'User logged in',
            'user' => $e->getUser(),
            'session' => $e->getSession()
        ]));
    }
);

Events summary

Event Name Functions Description
vippsas\login\events\LoggedInEvent VippsLogin::EVENT_USER_LOGGED_IN getUser(), getSession() Triggers when a user is logged in with Vipps.
vippsas\login\events\ContinueEvent VippsLogin::EVENT_USER_CONTINUED getSession() Triggers when a user continues with Vipps.
vippsas\login\events\RegisterEvent VippsLogin::EVENT_USER_CREATED getUser(), getSession() Triggers when a user registers with Vipps.
vippsas\login\events\ConnectEvent VippsLogin::EVENT_USER_CONNECTED_ACCOUNT getUser(), getSession() Triggers when a user connects an existing account to Vipps.

Example Code

Have a look at the twig template located here for some usage examples. The twig template uses Bulma CSS from a CDN and should work right out of the box if the plugin is installed correctly.
