        Advanced: Set{Child}List()

        The method syntax Set{Child}List varies depending on the name of the Child object. If your child object is called "Author" the method name will be SetAuthorList.

        The SetChildList() Relations method allows you to associate an array of child objects to a parent object. If the parent object already had children associated with it, those would become orphans (i.e. the association would be removed) as soon as SetChildList() is called. This method is useful when you want to either remove the relationship between a parent and its children or if you want to establish a new set of relations between some children and a parent object. After SetChildrenList() is called, the new parent-child links are not set until Save() is called. Therefore, one thing to be careful about, is if SetChildrenList() is called on a parent which had existing children and Save() is not subsequently called, then the old children will become orphans *AND* the new children will not be associated with the parent. Thus, it is always a good policy to call Save( ) anytime SetChildrenList( ) is called.

        //To associate a list of books associated with an author, simply do the following:
        $author = new Author( ) ; //create a parent object
        $author -> name = ‘Michael Critchton’ ;
        $author -> Save( ) ;
        $book = new Book( ) ; //create a child object
        $book -> title = " Jurassic Park" ;
        $book2 = new Book( ) ; //create a second child object
        $book2 -> t i t le = " State of Fear" ;

        $bookList = array();
        $bookList[] = $book;
        $bookList[] = $book2;

        $author->SetBookList($bookList); //sets the children list
        $author -> Save(); //Save and commit the changes to the database
