Why we build WordPress plugins to the coding standards

Anyone can make WordPress do something. Making it keep doing that after the next core update, the next theme change and the next plugin your client installs is the actual job.

The WordPress coding standards exist for that reason. Prefixed function names so nothing collides. Nonces and capability checks so forms cannot be abused. Escaping on output and sanitising on input, every time, so a plugin never becomes the hole a site gets hacked through.

It also means your plugin can go on WordPress.org or a marketplace without a rejection, and any WordPress developer can read it after us.

We run every plugin through PHPCS with the WordPress ruleset before it leaves our hands. It is a small habit that saves clients a lot of late-night emergencies.
