Foreign rates by Vedran Bejatovic

This plugin integrates live foreign exchange rates into a website, primarily for site owners who need to display current currency conversion information. It fetches data from the exchangeratesapi.io API and stores it locally for reliable access.

Shortcode: Insert a customizable currency converter directly into posts or sidebars using a simple shortcode. It allows users to select a base currency and view conversions for specific target currencies.

Widget: Add a currency display widget to any widget-ready area of the site. The widget includes its own configuration panel to set which currencies are shown.

Post Integration: Automatically display exchange rates at the bottom of qualifying posts based on specific criteria like category and age. This requires a small code addition to the site's theme files.

Scheduled Updates: Rates are updated automatically once per day using the site's internal scheduling system, with an option to use a more reliable server cron job for better consistency on low-traffic sites.

Local Data Storage: Downloaded rates are saved as a JSON file, reducing API calls and improving load times for the widget and post features.
