WordPress Update Handler

A WordPress package for updating custom plugins and themes based on an JSON REST API response from a custom update server.

Check out the WordPress GitHub Release API repository to learn how to quickly launch a custom update server that fetches releases from GitHub using Cloudflare Workers.

Plugins

This package expects your custom plugin info API to respond with the same shape as the WordPress plugin info API. However, if your API response has a different shape, you can map fields to those returned by your API.

Usage

Basic example:

<?php
/**
 * Plugin Name: My Plugin
 */

require __DIR__ . '/vendor/autoload.php';

use WP_Forge\WPUpdateHandler\PluginUpdater;

$url = 'https://my-update-api.com/plugins/plugin-name'; // Custom API GET endpoint

new PluginUpdater( __FILE__, $url );

Advanced example with data mapping and data overrides:

<?php
/**
 * Plugin Name: My Plugin
 */

require __DIR__ . '/vendor/autoload.php';

use WP_Forge\WPUpdateHandler\PluginUpdater;

$file = __FILE__; // Can be absolute path to main plugin file, or the plugin basename.
$url = 'https://my-update-api.com/plugins/plugin-name'; // Custom API GET endpoint

$pluginUpdater = new PluginUpdater( $file, $url );

/*
 * Keys are the fields that WordPress is expecting (look at the WP Plugin Info API response).
 * Values are the keys returned by your custom API.
 * 
 * Use dot notation to map nested keys.
 */
$pluginUpdater->setDataMap(
  [
    'requires' => 'requires.wp',          
    'requires' => 'requires.php',
    'banners.2x' => 'banners.retina',          
  ]
);

/*
 *  Explicitly set specific values that will be provided to WordPress.
 */
$pluginUpdater->setDataOverrides(
  [
    'banners' => [
      '2x' => 'https://my.cdn.com/banner-123-retina.jpg',
      '1x' => 'https://my.cdn.com/banner-123.jpg',
    ],
    'icons' => [
      '2x' => 'https://my.cdn.com/icon-123-retina.jpg',
      '1x' => 'https://my.cdn.com/icon-123.jpg',
    ],        
  ]
);

Themes

This package expects your custom theme info API to respond with the same shape as the WordPress theme info API. However, if your API response has a different shape, you can map fields to those returned by your API.

Usage

Basic example:

<?php
/**
 * Theme Name: My Theme
 */

require __DIR__ . '/vendor/autoload.php';

use WP_Forge\WPUpdateHandler\ThemeUpdater;

$url = 'https://my-update-api.com/theme/theme-name'; // Custom API GET endpoint

new ThemeUpdater( wp_get_theme('my-theme'), $url );

Advanced example with data mapping and data overrides:

<?php
/**
 * Theme Name: My Theme
 */

require __DIR__ . '/vendor/autoload.php';

use WP_Forge\WPUpdateHandler\ThemeUpdater;

$theme = wp_get_theme('my-theme'); // Get the theme's WP_Theme instance.
$url = 'https://my-update-api.com/themes/theme-name'; // Custom API GET endpoint

$themeUpdater = new ThemeUpdater( $file, $url );

/*
 * Keys are the fields that WordPress is expecting (look at the WP Theme Info API response).
 * Values are the keys returned by your custom API.
 * 
 * Use dot notation to map nested keys.
 */
$themeUpdater->setDataMap(
  [
    'requires' => 'requires.wp',          
    'requires' => 'requires.php',
    'banners.2x' => 'banners.retina',          
  ]
);

/*
 *  Explicitly set specific values that will be provided to WordPress.
 */
$themeUpdater->setDataOverrides(
  [
    'banners' => [
      '2x' => 'https://my.cdn.com/banner-123-retina.jpg',
      '1x' => 'https://my.cdn.com/banner-123.jpg',
    ],
    'icons' => [
      '2x' => 'https://my.cdn.com/icon-123-retina.jpg',
      '1x' => 'https://my.cdn.com/icon-123.jpg',
    ],        
  ]
);
