How To Implement A Many To Many Relationship To Form (E.g : Film -> R <- Actors)

Films Table - films

Field Name	Data Type
id	int(PK)
created_at	timestamp
name	varchar(255)
description	text

Actors Table - actors

Field Name	Data Type
id	int(PK)
name	varchar(255)

Films Actors Table - films_actors

Field Name	Data Type
id	int(PK)
films_id	int(11)
actors_id	int(11)

We need multiple select box, so we use select2 with datatable and relationship_table attribute

Code For Form of Films Controller

$this->form[] - ['label'=>'Name','type'=>'text','name'=>'name'];
$this->form[] = ['label'=>'Description','type'=>'textarea','name'=>'description'];
$this->form[] = ['label'=>'Actors','type'=>'select2','datatable'=>'actors,name','relationship_table'=>'films_actors'];
