Here's how I do it, I'm no cake guru, but it works...
Create your "Add Child" link in the Parent view like this:
$html->link("Add Child", array("controller"=>"ChildControllerName",
"action"=>"add", "parent_id"=>id_of_the_parent));
(creates a link that passes the parent id to the child controller's
add method)
In the child's add view:
if (isset($this->params['pass']['parent_id'])) {
$parent_id = $this->params['pass']['parent_id'];
}
else {
$parent_id = null;
}
And update the form field that points back to the parent to auto
select the parent:
echo $form->input('parent_id',array('class'=>'input', "selected"=>
$parent_id));
You can add an additional parameter to the $form->input to hide the
field (or use a hidden field instead)
Hope this helps.
