Advanced: Save(deep)


When an object is identified as “Parent” or "Sibling", POG generates the object with a slightly different Save CRUD method. The modified Save method is known as Save($DEEP). The Save($DEEP) method
extends the functionality of the traditional SAVE method by allowing you to recursively Save all child/sibling objects associated with the parent/sibling object. By default, parent objects are saved deep, i.e. when the $deep parameter is not specified. Save($deep) returns the object Id of the inserted/updated object.

PHP:
//To Save an object ‘deep’, simply do the following:
$book = new Book( ) ; //create a child object
$book -> title = " State of Fear" ;
$author = new Author ( ) ; //create a parent object
$author -> name = ‘Michael Critchton’ ;
$author -> AddBook($book) ;
$author -> Save ( t rue) ; //Saves both Author and Book objects
//Note: Save(true) is the same as Save():

//To Save an object ‘shallow’, simply do the following:
$book = new Book( ) ; //create a child object
$book -> title = " State of Fear" ;
$author = new Author ( ) ; //create a parent object
$author -> name = ‘Michael Critchton’ ;
$author -> AddBook($book) ;
$author -> Save ( false) ; //Saves only the Author object
//Note: Save(false) is different from Save():
