I have a many-to-one relationship, let's pretend it's many Leafs to Trees. Of course, I baked a form to add a Leaf to a Tree, and you can specify which Tree it is with a drop-down box ( tag) created by the form helper.
The only thing is, the SELECT box always defaults to Tree #1, but I would like it to default to the Tree it's being added to:
For example, calling
example.com/leaf/add/5 would bring up the interface to add a new Leaf to Tree #5. The dropdown box for
Leaf.tree_id would default to "Tree 5", instead of "Tree 1" that it currently defaults to.
What do I need to put in my Leaf controller and Leaf
view/add.ctp to do this?
You should never use
radio() etc.; it's terrible practice. You should use
$form->input('tree_id', array('options' => $trees));
Then in the controller:
$this->data['Leaf']['tree_id'] = $id;
In CakePHP 1.3, use
'default'=>value to select the default value in a select input:
$this->Form->input('Leaf.id', array('type'=>'select', 'label'=>'Leaf', 'options'=>$leafs, 'default'=>'3'));
