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.
