Overriding Symfony Form's Save Function - symfony1

Question

I have two issues, need some help with.
I have a table which is referenced by a foreign key to a second table:
member_child:
_attributes: { phpName: MemberChild }
id: { type: INTEGER, size: '11', primaryKey: true, autoIncrement: true, required: true }
member_id: { type: INTEGER, size: '11', required: true, foreignTable: member, foreignReference: id }
child_id: { type: INTEGER, size: '11', required: true, foreignTable: child, foreignReference: id }
and child:
child:
_attributes: { phpName: Child }
id: { type: INTEGER, size: '11', primaryKey: true, autoIncrement: true, required: true, onDelete: cascade }
username: { type: VARCHAR, size: '45', required: true, defaultValue: '' }
display: { type: TINYINT, size: '1', required: true, defaultValue: '1' }
...etc
(obviously this is propel)
Now, when I want to create a child object, using a form, I need to do two things:
On submit, submit a member id
override the doSave function so when the child is created, I can also create the member_child object
How can I accomplish these issues?

Answer 1

I agree, you can use embedForm like pankar said. Also you can override save method of your forms like this:
$this->childForm = new ChildForm();
$this->childMemberForm = new ChildMemberForm();
//binding, checking if form was sent etc.
if ($this->childForm->isValid() && $this->childMemberForm->isValid())
{
//save method should return saved object
$childObject = $this->childForm->save();
//therefore this id could be used by next object
$this->childMemberForm->save(childObject->getId());
}
I hope that will help you!

You can always use the built-in Symfony feature sfForm::embedForm in your parent form in order to save the child one, but I haven't figure out a a way of properly get this working.
One post I came across some time ago actually did provide me with the solution. Have a look and see if it fits your needs. Of course it's in Doctrine but I suppose it can be easily ported in Propel
