Conditional Logic Injection
Dynamic Joomla Class Referencing (JPK System)
Joomla Powers is JCB’s intelligent system for referencing Joomla framework and CMS classes using dynamic placeholders, called JPKs (Joomla Power Keys). These keys abstract the actual namespace of a Joomla class — and JCB will automatically replace them with the correct use statement and fully qualified class path during compilation, based on the Joomla version you're targeting.
This feature gives developers precise control over the behavior of generated components — such as permissions, filtering, workflow rules, or dynamic form manipulation — while still benefiting from full GUI-driven reusability.
Where You Can Inject
Models
Views
Controllers
How It Works
- Navigate to your view, model, or controller in the JCB GUI.
- Find the Custom Code section or designated code area.
- Choose the context (e.g., beforeSave, afterGetItem, display, allowDelete).
- Define your logic directly in the GUI.
- (Optional) Wrap your logic in a condition, using PHP or JCB placeholders.
- JCB will insert that logic at the corresponding point when compiling the component.
