WordPress.NamingConventions.PrefixAllGlobals.NonPrefixedConstantFound
Non-prefixed constant
The plugin defines a constant without a plugin-specific prefix.
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 constant so it cannot collide with code from another plugin.
- For public hooks, document the final hook name and keep it stable after release.
