one to many relationship problem in doctrine 2.0 - php

Question

I have an events table and events images table. I am having a form to add new event so i am also adding multiple images for that event. So that i am storing in event images table.
so how do i insert the data in both the tables..
<?php
/**
* #Entity
* #Table(name="events")
*/
class Default_Model_Event
{
/**
* #Id #Column(name="id", type="integer")
* #GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #Column(name="title", type="string")
*/
private $title;
/**
* #OneToMany(targetEntity="Default_Model_EventImages" mappedBy="eventimage_mapper")
*/
private $images_mapper;
}//end class
Event images model
<?php
/**
* #Entity
* #Table(name="event_images")
*/
class Default_Model_EventImages
{
/**
* #Id #Column(name="id", type="integer")
* #GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #Column(name="name", type="string")
*/
private $name;
/**
* #ManyToOne(targetEntity="Default_Model_Event", inversedBy="images_mapper")
* #JoinColumn(name="event_id", referencedColumnName="id")
*/
private $eventimage_mapper;
}//end class
From my controller how do i save the data now.. I am thinking of first saving the event data and than will get that id and than will save the events images by loop.. than i am not getting what will be the use of the one to many mapper i have created..
I am using zend framework 1.11 and Doctrine 2.0

At first you need to create getters, setters to your objects. Then you just create
$event = new Default_Model_Event();
$em->persist($event);
while (something) {
$image = new Default_Model_EventImages();
$image->setEventimage_mapper($event);
$em->persist($image);
}
$em->flush();
Just read the Doctrine documentation on associations. It will help for sure.
