Constructor & Destructor Documentation

◆ __construct()

portfolio_plugin_base::__construct (   $instanceid,
  $record = null 
)

Construct a plugin instance.

Subclasses should not need to override this unless they're doing something special and should call parent::__construct afterwards.

Parameters
int$instanceidid of plugin instance to construct
mixed$recordstdclass object or named array - use this if you already have the record to avoid another query
Return values
portfolio_plugin_base
