Authorize Endpoint definieren im OpenID Connect Wordpress plugin zu ("Login Endpoint URL"):

Beide peers (WooCommerce+Reclaim und localen GNUnet peer "verbinden")
-- oder beim Export von GNUnet via qemu: bind_to von REST auf 0.0.0.0 setzen, damit Qemu zugriff erlaubt.


=============================


Integration Notes:
==================

Add OIDC button using (either)

		<?php do_action( 'woocommerce_before_checkout_registration_form', $checkout ); ?>

		<?php if ( $checkout->get_checkout_fields( 'account' ) ) : ?>

			<div class="create-account">
				<?php foreach ( $checkout->get_checkout_fields( 'account' ) as $key => $field ) : ?>
					<?php woocommerce_form_field( $key, $field, $checkout->get_value( $key ) ); ?>
				<?php endforeach; ?>
				<div class="clear"></div>
			</div>

		<?php endif; ?>

		<?php do_action( 'woocommerce_after_checkout_registration_form', $checkout ); ?>

of those hooks from
https://github.com/woocommerce/woocommerce/blob/bdf77f5648fb44b86b19ac4f8a01536b1ee6baa1/templates/checkout/form-billing.php


=> ideal: call hook of OIDC plugin that OIDC plugin installed for the 'main' login button of WordPress.



OIDC plugin uses existing hook
(see includes/openid-connect-generic-login-form.php) as this:

>>>
$login_form = new self( $settings, $client_wrapper );
add_filter( 'login_message', array( $login_form, 'handle_login_page' ), 99 );
add_shortcode( 'openid_connect_generic_login_button', array( $login_form, 'make_login_button' ) );
<<<

so something like this must be added to the hook above!





daggerhart-openid-connect-generic
=================================

Modify "Login with OpenID" to "Login with Re:claimID" using this hook:

#### `openid-connect-generic-login-button-text`


Modify the login button text. Default value is `__( 'Login with OpenID Connect' )`.

Provides 1 argument: the current login button text.

```
add_filter('openid-connect-generic-login-button-text', function( $text ) {
    $text = __('Login to my super cool IDP server');

    return $text;
});
```


* `openid-connect-generic-last-id-token-claim` - The user's most recent `id_token` claim, decoded and stored as an array.
  => here is the data we want from the user (to put into the woocommerce form)





Required fields in billing form:
NOTE: if 'email' is available, it is already used, seems I may not even need the hook!


{"billing":{"billing_first_name":{"label":"First name","required":true,"class":["form-row-first"],"autocomplete":"given-name","priority":10},"billing_last_name":{"label":"Last name","required":true,"class":["form-row-last"],"autocomplete":"family-name","priority":20},"billing_company":{"label":"Company name","class":["form-row-wide"],"autocomplete":"organization","priority":30,"required":false},"billing_country":{"type":"country","label":"Country \/ Region","required":true,"class":["form-row-wide","address-field","update_totals_on_change"],"autocomplete":"country","priority":40},"billing_address_1":{"label":"Street address","placeholder":"House number and street name","required":true,"class":["form-row-wide","address-field"],"autocomplete":"address-line1","priority":50},"billing_address_2":{"placeholder":"Apartment, suite, unit, etc. (optional)","class":["form-row-wide","address-field"],"autocomplete":"address-line2","priority":60,"required":false},"billing_city":{"label":"Town \/ City","required":true,"class":["form-row-wide","address-field"],"autocomplete":"address-level2","priority":70},"billing_state":{"type":"state","label":"State \/ County","required":false,"class":["form-row-wide","address-field"],"validate":["state"],"autocomplete":"address-level1","priority":80,"country_field":"billing_country","country":"AF"},"billing_postcode":{"label":"Postcode \/ ZIP","required":true,"class":["form-row-wide","address-field"],"validate":["postcode"],"autocomplete":"postal-code","priority":90},"billing_phone":{"label":"Phone","required":true,"type":"tel","class":["form-row-wide"],"validate":["phone"],"autocomplete":"tel","priority":100},"billing_email":{"label":"Email address","required":true,"type":"email","class":["form-row-wide"],"validate":["email"],"autocomplete":"email","priority":110}},"shipping":{"shipping_first_name":{"label":"First name","required":true,"class":["form-row-first"],"autocomplete":"given-name","priority":10},"shipping_last_name":{"label":"Last name","required":true,"class":["form-row-last"],"autocomplete":"family-name","priority":20},"shipping_company":{"label":"Company name","class":["form-row-wide"],"autocomplete":"organization","priority":30,"required":false},"shipping_country":{"type":"country","label":"Country \/ Region","required":true,"class":["form-row-wide","address-field","update_totals_on_change"],"autocomplete":"country","priority":40},"shipping_address_1":{"label":"Street address","placeholder":"House number and street name","required":true,"class":["form-row-wide","address-field"],"autocomplete":"address-line1","priority":50},"shipping_address_2":{"placeholder":"Apartment, suite, unit, etc. (optional)","class":["form-row-wide","address-field"],"autocomplete":"address-line2","priority":60,"required":false},"shipping_city":{"label":"Town \/ City","required":true,"class":["form-row-wide","address-field"],"autocomplete":"address-level2","priority":70},"shipping_state":{"type":"state","label":"State \/ County","required":false,"class":["form-row-wide","address-field"],"validate":["state"],"autocomplete":"address-level1","priority":80,"country_field":"shipping_country","country":"AF"},"shipping_postcode":{"label":"Postcode \/ ZIP","required":true,"class":["form-row-wide","address-field"],"validate":["postcode"],"autocomplete":"postal-code","priority":90}},"account":{"account_username":{"type":"text","label":"Account username","required":true,"placeholder":"Username"},"account_password":{"type":"password","label":"Create account password","required":true,"placeholder":"Password"}},"order":{"order_comments":{"type":"textarea","class":["notes"],"label":"Order notes","placeholder":"Notes about your order, e.g. special notes for delivery."}}}
