Deprecated Warning: Dynamic Property Creation in Oxygen Plugin

[seierup]

I'm encountering multiple deprecation warnings in the Oxygen Gutenberg and Oxygen WooCommerce plugins due to the creation of dynamic properties. These warnings occur since PHP 8.2 deprecated dynamic property creation, which affects compatibility.

Error Log:

PHP Deprecated: Creation of dynamic property OxygenGutenbergPluginUpdater::$prefix is deprecated in /wp-content/plugins/oxygen-gutenberg/admin/includes/updater/edd-updater.php on line 19
PHP Deprecated: Creation of dynamic property OxyWooCommerce::$buttons_settings is deprecated in /wp-content/plugins/oxygen-woocommerce/OxyWooCommerce.php on line 40
...

The issue occurs across multiple files, including:

• oxygen-gutenberg/admin/includes/updater/edd-updater.php
• oxygen-woocommerce/OxyWooCommerce.php

Steps to Reproduce:

• PHP 8.2.
• Activate the Oxygen Gutenberg and Oxygen WooCommerce plugins.
• Observe the PHP deprecation warnings in the error log.
• Expected Behavior: The plugins should be compatible with PHP 8.2 without triggering deprecated warnings.

Proposed Solution: Replace dynamic property assignment with properly defined class properties to ensure compatibility with PHP 8.2.

Environment:

WordPress Version: 6.7.1
PHP Version: 8.2
Plugin Versions:

• Oxygen Version: 4.9.1
• Oxygen Gutenberg Version: 1.4.5
• Oxygen WooCommerce Version: 2.0.1
