README

This SDK allows you to easily plug your WordPress plugins into the WPNextShip licensing and update system.

1. Installation

Copy the lib folder into your plugin's directory.

2. Initialization

Initialize the SDK in your main plugin file according to your desired menu placement.

Option A: Top-Level Menu

This will create a dedicated menu item for your plugin settings/licensing.

// wp-content/plugins/my-plugin/my-plugin.php

require_once plugin_dir_path( __FILE__ ) . 'lib/sdk-template/wp-nextship-loader.php';

add_action( 'plugins_loaded', function() {
    WPNextShip_SDK_Manager::init( array(
        'slug'    => 'my-plugin',
        'version' => '1.0.0', // Current plugin version
        'file'    => plugin_basename( __FILE__ ), // e.g., 'my-plugin/my-plugin.php'
    ) );
} );

Option B: Submenu (e.g., Settings)

This will place the "License" page under an existing parent menu, such as Settings (options-general.php) or your own custom menu.

// wp-content/plugins/my-plugin/my-plugin.php

require_once plugin_dir_path( __FILE__ ) . 'lib/sdk-template/wp-nextship-loader.php';

add_action( 'plugins_loaded', function() {
    WPNextShip_SDK_Manager::init( array(
        'slug'        => 'my-plugin',
        'version'     => '1.0.0',
        'file'        => plugin_basename( __FILE__ ),
        'parent_slug' => 'options-general.php', // Adds under Settings
    ) );
} );

3. How It Works

Licensing

• The SDK creates a "License" page.
• Users enter their License Key and Email.
• Upon activation, the SDK validates the key against your WPNextShip instance.
• Success stores activation status in _wpnextship_license_{slug}.

Updates

• The SDK hooks into WordPress update checks.
• It sends the current version and license key to your API.
• If a new version is available, it injects the update package into the WordPress updater.
• Regular WordPress update flows work seamlessly.

4. File Structure

• wp-nextship-loader.php: Main entry point.
• src/Licensing.php: Handles menu creation and activation UI.
• src/Updater.php: Handles pre_set_site_transient_update_plugins filter.

5. Troubleshooting

• Check Logs: Ensure your API URL is reachable from the site.
• License Key: Updates only work with an active license.
• Slug Match: Ensure the slug passed to init matches the product slug in your WPNextShip dashboard.
