Adds Pontifex exam planning, registration and payment functionality to WordPress using shortcodes.

Description

Pontifex OI is a WordPress plugin that connects your website to the Pontifex Open Inschrijvingen SOAP API. It enables you to display exam planning, collect candidate registrations, and process payments directly within WordPress.

The plugin uses a shortcode-based workflow, making it easy to place each step of the process on its own page. It is built with modern object-oriented PHP (8.1+), follows WordPress coding standards, and is designed to be extendable.

Features

• API Sync: Display exam planning retrieved from the Pontifex SOAP API.
• Frontend Workflow: Registration forms for candidates via shortcodes.
• Payments: Seamless payment handling via Mollie integration.
• Modern Stack: REST API endpoints for frontend interaction and headless potential.
• Automation: Daily synchronization using WordPress Cron (03:15 local time).
• Developer Friendly: Object-oriented, Composer-ready, and overrideable templates.

Installation

1. Upload the pontifex-oi folder to the /wp-content/plugins/ directory.
2. Activate the plugin via the Plugins menu in WordPress.
