Kurs NBP

kurs_nbp is a simple Drupal 8 module for fetching exchange rates from NBP (Narodowy Bank Polski).

It provides customizable block for displaying selected exchange rates.

To install the module, follow these steps:

1. Download latest .zip (or .tar.gz) archive.
2. In your Drupal website, go to Manage > Extend > Install new module.
3. Drag the archive file on the Browse... button or select it by file dialogue.
4. Click install.
5. Navigate to Manage > Extend and type in the search box "Kurs NBP".
6. Check the box near the module name, and click Install.

Now you can start using it. If you got stuck on anything, check the Troubleshooting section of this readme.

To uninstall the module, go to Manage > Extend, select "Uninstall" tab and remove it.

For complete removal you can delete the kurs_nbp (or kurs_nbp-master) directory from your Drupal installation - you can probably find it in htdocs/modules.

Usage

After a succesful installation, you can make use of the new 'Kurs NBP' block in your website.

To do this, navigate to Manage > Structure > Block layout and press Place block button near the name of section where you want to put your block.

Now find "Kurs NBP" block and press Place block near it - a popup will show up, allowing you to manipulate the properties of this block instance - see Variables below.

After you have done configuring, press Save block. Now you can go back to home page of your site and see the exchange rates.

For now, you an place as many blocks as you want, however they will share the same style - different currencies works fine.

This field can be feed with any number of vaild three letter currency names, case insensitive.
