WordPress.DB.RestrictedFunctions.mysql_mysqli_prepare
mysql mysqli prepare
The plugin uses a raw MySQL extension or class instead of WordPress database APIs.
Why It Shows Up
The scan found `mysql_*`, `mysqli_*`, PDO MySQL, or related database functions in plugin code.
Why It Matters
Bypassing `$wpdb` can ignore WordPress database configuration, escaping conventions, character sets, and compatibility layers.
How to Fix
- Replace raw MySQL calls with `$wpdb` methods or higher-level WordPress APIs.
- Use `$wpdb->prepare()` for dynamic values.
- If a third-party library requires a database connection, isolate it and document why WordPress APIs cannot be used.
