WordPress.NamingConventions.PrefixAllGlobals.NonPrefixedInterfaceFound

Non-prefixed interface

The plugin defines a interface without a plugin-specific prefix.

medium weight

Why It Shows Up

WordPress loads many plugins in the same PHP runtime. Plugin Check found a global symbol or hook name that is not clearly namespaced to this plugin.

Why It Matters

Unprefixed globals can collide with WordPress core, themes, or other plugins, causing fatal errors, overwritten values, or handlers running in the wrong context.

How to Fix

  • Choose a short, unique prefix or namespace based on the plugin slug or vendor name.
  • Rename the interface so it cannot collide with code from another plugin.
  • For public hooks, document the final hook name and keep it stable after release.
