A set of related foundational classes to kick-start WordPress plugin development. This package contains many abstractions useful for building a WordPress plugin.


Documentation for this module and the rest of the DWS WP Framework can be found here.


The package is designed to be installed via Composer. It may work as a stand-alone but that is not officially supported. The package's name is deep-web-solutions/wp-framework-foundations.

If the package will be used outside a composer-based installation, e.g. inside a regular WP plugin, you should install using the --ignore-platform-reqs option. If you don't do that, the bundled DWS WordPress Framework - Bootstrapper package will only be able to perform checks for the WordPress version because composer will throw an error in case of an incompatible PHP version.


Contributions both in the form of bug-reports and pull requests are more than welcome!

Frequently Asked Questions

  • Will you support earlier versions of WordPress and PHP?

Unfortunately not. PHP 7.3 is close to EOL (March 2021), and we consider 7.4 to provide a few features that are absolutely amazing. Moreover, WP 5.5 introduced a few new features that we really want to use as well, and we consider it to be one of the first versions of WordPress to have packed a more-or-less mature version of Gutenberg.

If you're using older versions of either one, you should really consider upgrading at least for security reasons.

  • Is this bug-free?

Hopefully yes, probably not. If you found any problems, please raise an issue on Github!
