README

CI Static Analysis

A library for installing / activating other plugins. Authored by the development team at StellarWP and provided free for the WordPress community.

Installation

It's recommended that you install Schema as a project dependency via Composer:

composer require stellarwp/installer

We actually recommend that this library gets included in your project using Strauss.

Luckily, adding Strauss to your composer.json is only slightly more complicated than adding a typical dependency, so checkout our strauss docs.

Handling text domains

This library has strings that are run through WordPress translation functions. Because of this, there's an extra step that needs to be taken to ensure that the placeholder %TEXTDOMAIN% is replaced with your project's text domain.

If you are using Strauss as a .phar file (recommended)

"scripts": {
	"strauss": [
		"test -f ./bin/strauss.phar || curl -o bin/strauss.phar -L -C - https://github.com/BrianHenryIE/strauss/releases/download/0.13.0/strauss.phar",
		"vendor/stellarwp/installer/bin/set-domain domain=YOUR_PROJECTS_TEXT_DOMAIN",
		"@php bin/strauss.phar"
	]
}

If you are using Strauss from within your vendor/bin directory

"scripts": {
    "strauss": [
      "vendor/stellarwp/installer/bin/set-domain domain=YOUR_PROJECTS_TEXT_DOMAIN",
      "vendor/bin/strauss"
    ]
}

Initialization

During the plugins_loaded action, initialize the installer.

namespace StellarWP\Installer\Config;
namespace StellarWP\Installer\Installer;

add_action( 'plugins_loaded', function () {
	Config::set_hook_prefix( 'boomshakalaka' );
	Installer::init();
} );

Registering a plugin

Registering plugins for installation should be done during (or after) the plugins_loaded action.

$installer->register_plugin( $slug, $plugin_name, $download_link, $did_action );

Simple registration

use StellarWP\Installer\Installer;

add_action( 'plugins_loaded', function () {
	$installer = Installer::get();
	$installer->register_plugin( 'event-tickets', 'Event Tickets' );
} );

Registration with download link

use StellarWP\Installer\Installer;

add_action( 'plugins_loaded', function () {
	$installer = Installer::get();
	$installer->register_plugin( 'event-tickets', 'Event Tickets', 'https://example.com/event-tickets.zip' );
} );

Registration with an action indicating that the plugin is active

use StellarWP\Installer\Installer;

add_action( 'plugins_loaded', function () {
	$installer = Installer::get();
	$installer->register_plugin( 'event-tickets', 'Event Tickets', null, 'event_tickets_plugin_loaded' );
} );

Rendering an install/activate button

Buttons are the main point of this library. You can get or render a button. When you do, the relevant JavaScript will be enqueued to hook the button up with admin-ajax.php.

Render a button

use StellarWP\Installer\Installer;

Installer::get()->render_plugin_button( 'event-tickets', 'install', 'Install Event Tickets' );

Get a button

use StellarWP\Installer\Installer;

Installer::get()->get_plugin_button( 'event-tickets', 'install', 'Install Event Tickets' );

Get or render a button and redirect

use StellarWP\Installer\Installer;

// Get it.
$button = Installer::get()->get_plugin_button( 'event-tickets', 'install', 'Install Event Tickets', $redirect_url );

// Or render it.
Installer::get()->render_plugin_button( 'event-tickets', 'install', 'Install Event Tickets', $redirect_url );
