Introduction
------------

[](#introduction)

DoubleOptIn extends Silverstripe and Userforms to implement a Double-Opt-In solution that is often required by new GDPR law. It will add a checkbox to Userforms to send a verification email before the submission/email is viewable/sent.

Requirements
------------

[](#requirements)

- silverstripe/framework ^4.0
- silverstripe/admin ^1.0
- silverstripe/userforms ^5.0

This module was only tested on the newest 4.4.

Installation
------------

[](#installation)

```
composer require zazama/doubleoptin

```

### YAML configuration

[](#yaml-configuration)

```
# set a route for verification links
SilverStripe\Control\Director:
  rules:
    'verify': Zazama\DoubleOptIn\Controllers\VerificationController
Zazama\DoubleOptIn\Models\EmailVerification:
  url_segment: 'verify'
  # subject is ignored with Userforms, because that's set in admin frontend.
  subject: 'Email Verification'
# set sender for the verification email
Zazama\DoubleOptIn\Services\EmailSender:
  email_sender: 'example@yourdomain.com'
```

### Userforms settings

[](#userforms-settings)

- To enable DoubleOptIn in a Userforms page, go to the Configuration tab and click "Enable Double-Opt-In"
- Choose the Double-Opt-In E-Mail field (required, too)
- Enter your verification email subject.

### Usage with normal forms

[](#usage-with-normal-forms)

```
    use Zazama\DoubleOptIn\Models\EmailVerification;

    public function handleFormVerification($data, $subject) {
        $email = $data['email'];
        $emailVerification = EmailVerification::create();
        $emailVerification->init($email);
        $emailVerification->send($subject);
        $emailVerification->write();
    }

    public function tokenChecks() {
        EmailVerification::IsSuccess($token); //bool
        EmailVerification::IsAlreadyVerified($token); //bool
        EmailVerification::IsBadToken($token); //bool
        EmailVerification::TokenType($token); //string
    }
```

### Templates

[](#templates)

The following templates can be overriden:

- Zazama\\DoubleOptIn\\Layout\\Verification\_Success
- Zazama\\DoubleOptIn\\Layout\\Verification\_BadToken
- Zazama\\DoubleOptIn\\Layout\\Verification\_AlreadyVerified
- Zazama\\DoubleOptIn\\Email\\Email

If you just want to change the text, you can change the language strings.

### Extension hooks

[](#extension-hooks)

There are extension hooks provided to use the Verification controller.

```
class x extends Zazama\DoubleOptIn\Controllers\VerificationController {
  # called when successfully verified
  public function updateSuccess($token) {}

  # called when verification token is wrong / not provided
  public function updateBadToken() {}

  # called when verification token is already verified
  public function updateAlreadyVerified() {}
}

class y extends Zazama\DoubleOptIn\Models\EmailVerification {
  # change generated token
  public function updateGenerateToken($token) {}

  # change link
  public function updateLink($link) {}

  # change subject
  public function updateSubject($subject) {}
}
```
