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	$instanceid	id of plugin instance to construct
mixed	$record	stdclass object or named array - use this if you already have the record to avoid another query

Return values

portfolio_plugin_base

Member Function Documentation

◆ admin_config_form()

static portfolio_plugin_base::admin_config_form ( & $mform )

static

mform to display to the admin configuring the plugin.

If your plugin can't be configured by the admin,

See also: has_admin_config Don't bother overriding this function. This function can be called statically or non statically, depending on whether it's creating a new instance (statically), or editing an existing one (non statically)

Parameters

moodleform $mform passed by reference, add elements to it.
