Advanced: Set{Parent}()

The method syntax Set{Parent} varies depending on the name of the Parent object. If your parent object is called "Book" the method name will be SetBook.

The SetParent () Relations method allows you to associate a parent object to a child object. When a child object is generated, POG automatically adds a ParentId attribute to the child object. When SetParent() is called, POG essentially associates the object id of the parent to the child

//To set an Author object as the parent of a child object:
$author = new Author ( ) ; //create a parent object
$author -> name = ‘Mi chael Cri tchton’;
$author -> Save( ) ;
$book = new Book( ) ; //create a child object
$book -> t i t le = " State of Fear" ;
$book -> SetAuthor ($author ) ; // this associates the parent to the child
$book -> Save( ) ;

Not e:
chi ld - > SetParent i s a lmost equivalent to parent -> AddChi ld
The main di fference is that SetParent requires that the parent object be previously saved before associat ing a chi ld to i t . Depending on the code context , the developer can choose whi ch method is most convenient to him/her .
