+++ Creating related records +++ Creating related records
When accessing related records and if those records do not exists Doctrine automatically creates new records. Accessing related records in Doctrine is easy: you can use exactly the same getters and setters as for the record properties.
You can use any of the three ways above, however the last one is the recommended one for array portability purposes.
<code type="php"> <code type="php">
// NOTE: related record have always the first letter in uppercase $user->Email;
$email = $user->Email;
$email->address = 'jackdaniels@drinkmore.info'; $user->get('Email');
$user->save(); $user['Email'];
</code>
// alternative: When accessing a one-to-one related record that doesn't exist, Doctrine automatically creates the object. So for example the following code is possible:
$user->Email->address = 'jackdaniels@drinkmore.info'; <code type="php">
$user = new User();
$user->name = 'some user';
$user->Email->address = 'some@one.info';
// saves the user and the associated email
$user->save(); $user->save();
</code> </code>
When accessing one-to-many related records, Doctrine creates a Doctrine_Collection for the related component. Lets say we have users and phonenumbers and their relations is one-to-many. You can add phonenumbers easily as shown above:
<code type="php">
$user = new User();
$user->name = 'some user';
$user->Phonenumber[]->phonenumber = '123 123';
$user->Phonenumber[]->phonenumber = '456 123';
$user->Phonenumber[]->phonenumber = '123 777';
// saves the user and the associated phonenumbers
$user->save();
</code>
