...

To render simple checkout form just call the widget in the view, it will automatically register the scripts. Check stripe documentation for more options.

use alkurn\stripe\StripeCheckout;

<?= 
StripeCheckout::widget([
    'action' => '/',
    'name' => 'Yoga Trainer',
    'description' => 'Yoga Trainer ($40.00)',
    'amount' => 40,
    'image' => '/128x128.png',
]);
?>

Custom checkout form is an extended version of simple form, but you can customize the button (see buttonOptions) and handle token as you want (tokenFunction).

use alkurn\stripe\StripeCheckoutCustom;

<?= 
StripeCheckoutCustom::widget([
    'action' => '/',
    'name' => 'Demo test',
    'description' => '2 widgets ($20.00)',
    'amount' => 2000,
    'image' => '/128x128.png',
    'buttonOptions' => [
        'class' => 'btn btn-lg btn-success',
    ],
    'tokenFunction' => new JsExpression('function(token) { 
                alert("Here you should control your token."); 
    }'),
    'openedFunction' => new JsExpression('function() { 
                alert("Model opened"); 
    }'),
    'closedFunction' => new JsExpression('function() { 
                alert("Model closed"); 
    }'),
]);
?>

Example of a custom form. StripeForm is an extended ActiveForm so you can perform validation of amount and other attributes you want. Use of Jquery Payment library is optional, you can disable format and validation and write your own implementation. You can also change JsExpression for response and request handlers.

use alkurn\stripe\StripeForm;

 <?php
 $form = StripeForm::begin([
             'tokenInputName' => 'stripeToken',
             'errorContainerId' => 'payment-errors',
             'brandContainerId' => 'cc-brand',
             'errorClass' => 'has-error',
             'applyJqueryPaymentFormat' => true,
             'applyJqueryPaymentValidation' => true,
             'options' => ['autocomplete' => 'on']
 ]);
 ?>

 <div class="form-group">
     <label for="number" class="control-label">Card number</label>
     <span id="cc-brand"></span>
     <?= $form->numberInput() ?>
 </div>

 <div class="form-group">
     <label for="cvc" class="control-label">CVC</label>
     <?= $form->cvcInput() ?>
 </div>

 <!-- Use month and year in the same input. -->
 <div class="form-group">
     <label for="exp-month-year" class="control-label">Card expiry</label>
     <?= $form->monthAndYearInput() ?>
 </div>

 <!-- OR in two separate inputs. -->
 <div class="form-group">
     <label for="exp-month" class="control-label">Month</label>
     <?= $form->monthInput() ?>
 </div>

 <div class="form-group">
     <label for="exp-year" class="control-label">Year</label>
     <?= $form->yearInput() ?>
 </div>

 <div id="payment-errors"></div>
 
 <?= Html::submitButton('Submit'); ?>
 
 <?php StripeForm::end(); ?>
 
<?php
use alkurn\stripe\StripeConnect;


$provider = new StripeConnect([
    'clientId'          => '{stripe-client-id}',
    'clientSecret'      => '{stripe-client-secret}',
    'redirectUri'       => 'https://example.com/callback-url',
]);

if (!isset($_GET['code'])) {

    // If we don't have an authorization code then get one
    $authUrl = $provider->getAuthorizationUrl();
    $_SESSION['oauth2state'] = $provider->getState();
    header('Location: '.$authUrl);
    exit;

// Check given state against previously stored one to mitigate CSRF attack
} elseif (empty($_GET['state']) || ($_GET['state'] !== $_SESSION['oauth2state'])) {

    unset($_SESSION['oauth2state']);
    exit('Invalid state');

} else {

    // Try to get an access token (using the authorization code grant)
    $token = $provider->getAccessToken('authorization_code', [
        'code' => $_GET['code']
    ]);

    // Optional: Now you have a token you can look up a users profile data
    try {

        // We got an access token, let's now get the user's details
        $account = $provider->getResourceOwner($token);

        // Use these details to create a new profile
        printf('Hello %s!', $account->getDisplayName());

    } catch (Exception $e) {

        // Failed to get user details
        exit('Oh dear...');
    }

    // Use this to interact with an API on the users behalf
    echo $token->getToken();
