You have register your action as "payments/checkout/stripe" and your from is calling "card"

You need your action to be:

elgg_register_action('card', __DIR__ . '/actions/payments/checkout/card.php', 'public');

Maybe have a look at http://learn.elgg.org/en/2.3/guides/actions.html (for Elgg 2.3) or http://learn.elgg.org/en/stable/guides/actions.html (for Elgg 3.0)

Thank You @Rohit Gupta It works.

I hope someone can answer this for you.

@Gaurav Garg: I worked with stripe and stripe_subscriptions plugins some time ago for Elgg 2.3.x and made some changes in order to be compatible with latest stripe-php library.

They are available at https://github.com/nlybe/stripe_subscriptions and https://github.com/nlybe/stripe.

In any case you have to read Stripe documentation to understand how it works, so it will help you using the plugins for Elgg.

Thanks @nikos, but i want know that in https://github.com/nlybe/stripe. plugin the codes given for card and create charges, where they will be added? or which view should i use to start plugin.

actually i am unable to trigger the plugin after activating it from administer page.
