LightningPayment

This simple plugin allows users to join the mediawiki group "trusted" by paying.

Requirements

The system requires either:

• A c-lightning node with lightning-charge configured and installed or

• an lnbits.com account.

• This extension requires ParserFunctions extension, so if you don't already have it:

  • Download it from here
  • Place it to your extensions/ folder on the mediawiki server/docker.

Installation

• Copy the files from this repository to the extensions/LightningPayment folder on the mediawiki server/docker (e.g. docker cp LightningPayment <containerid>:/var/www/html/extensions/) or, while your working directory is the extensions folder, clone the project with git clone https://github.com/pseudozach/LightningPayment.git

Configuration

Add these settings to the bottom of the LocalSettings.php file.

• You need to set the LightningBackend you are using and configure it: lightningcharge or lnbits.

• For lightning-charge

  • Set $wgLightningPaymentNodeUrl to lightning-charge api endpoint where mediawiki server can access it.
  • Set $wgLightningPaymentApiToken to your lightning-charge api token.

• For lnbits.com

  • Set $wgLNBitsApiKey to "Invoice/read key" from your lnbits wallet dashboard.

Usage

You should be able to access the payment page here:

http://localhost:8080/index.php/Special:LightningPayment

It should display a lightning invoice and QR code image.

Newly created accounts won't be able to edit until they have paid.

Refresh the page after payment and user will have edit rights.
