GitHub Updater Demo

WordPress plugin to demonstrate how GitHubUpdater can enable WordPress to check for and update a custom plugin that's hosted in either a public or private repository on GitHub.

Plugin Header Fields

The following plugin header fields are being used by GitHubUpdater.

Version (Required)

Specify your current plugin's version. For example:

Version: 1.0.0

Version is used to compare the installed plugin with the latest one on GitHub to determine if there are updates.

Plugin URI (Required)

Specify URL to your plugin's changelog. For example:

Plugin URI: https://ryansechrest.github.io/github-updater-demo

Page will be embedded in a modal when viewing plugin details.

Update URI (Required)

Specify URL to your plugin's repository on GitHub. For example:

Update URI: https://github.com/ryansechrest/github-updater-demo

Repository is used as the source for plugin updates.

Tested up to (Optional)

Specify highest version of WordPress that your plugin was tested on. For example

Tested up to: 6.6

Will show the following compatibility message on Dashboard > Updates when your plugin has an update:

Compatibility with WordPress 6.6: 100% (according to its author)

Getting Started

Copy GitHubUpdater.php into your plugin
Update namespace to match your plugin
Require GitHubUpdater.php in your plugin
Instantiate GitHubUpdater in your plugin

Setup

How to add and configure GitHubUpdater for your plugin.

Instantiate GitHubUpdater (Required)

Instantiate GitHubUpdater and pass in the absolute path to your root plugin file.

$gitHubUpdater = new GitHubUpdater(__FILE__);

For example, __FILE__ might resolve to:

/var/www/domains/example.org/wp-content/plugins/<pluginDir>/<pluginSlug>.php

Configure: Production Branch (Optional)

If your production branch is not the default main, then specify it:

$gitHubUpdater->setBranch('master');

Configure: Personal Access Token (Optional)

If your GitHub repository is private, then set your access token:

$gitHubUpdater->setAccessToken('github_pat_XXXXXXXXX');

It's not recommended to hardcode a token like you see above.

Either define a constant in wp-config.php:

define( 'GITHUB_ACCESS_TOKEN', 'github_pat_XXXXXXXXXX' );

And then pass in the constant:

$gitHubUpdater->setAccessToken(GITHUB_ACCESS_TOKEN);

Or save your access token in wp_options and pass it via get_option():

$gitHubUpdater->setAccessToken(get_option('github_access_token'));

Add GitHubUpdater (Required)

Add all necessary hooks to WordPress to keep your plugin updated moving forward:

$gitHubUpdater->add();

This should be the last method call after GitHubUpdater has been configured.
