Joomla plugin event triggers

Joomla plugin event triggers

index.php

Each plugin type  has its own set of events that trigger these plugins to execute. Each plugin can use one or more event triggers but there is no need to use all the event triggers available, just pick out the ones you need. You also have the freedom to create your own custom plugin event triggers in your components, however, that is also outside the scope of this book. The following table summarizes the types of plugins available and their respective event triggers:
