Advanced: Add{Sibling}()


NOTE:
The method syntax Add{Sibling} varies depending on the name of the Sibling object. If your sibling object is called "Author" the method name will be AddAuthor.


The Add {Sibling} Relations method allows you to associate a sibling object to another sibling object. The 2nd sibling object is added to a private sibling Array inside the 1st sibling object. The sibling object is not saved to the database until Save() is called.

CODE EXAMPLES:
Let’s consider the example of Magazines and Subscribers. A Magazine has many subscribers and each subscriber can subscribe to 1 or more magazines. To prevent circular dependencies, A sibling cannot add each other successively within the same code block.
For example:
$silbing1 -> AddSibling2($sibling2)
$sibling2 -> AddSibling1($sibling1) (NOT ALLOWED IF sibling 1 already references sibling 2)


PHP:
//To Add a book object to an Author object, simply do the following:
$magazine= new Magazine( ) ; //create a magazine object
$magazine-> title = "Popular Mechanics" ;
$subscriber = new Subscriber( ) ; //create a subscriber object
$subscriber-> name = 'John Smith';
$subscriber-> AddMagazine($magazine) ; //associate magazine to subscriber
