Your add function shouldn't really need a parameter associated with
it. Edit/View/Delete controller actions use it, but there is no id
associated with an add. When you call add, you are calling /country/
add without a parameter, but your $region_id = null section is
defaulting it to 0.
I'm assuming you want to call /country/add/3 to make whatever country
you next add be placed in the region_id equal to 3 in the following
example.
function add($region_id = null)
{
if (empty($this->data))
{
$this->set('region_id', $region_id);
}
else
{
if ($this->Country->save($this->data))
{
$this->flash('New country added.', '/countries', 2);
}
}
}
You could also do the URL /counter/add?region=3 as follows...
function add()
{
// On first page load, set region id if it was passed in the url
if (empty($this->data))
if (isset($this->params['url']['region']))
{
$this->data['Country']['region_id'] = $this->params['url']
['region'];
}
}
else
{
if ($this->Country->save($this->data))
{
$this->flash('New country added.', '/countries', 2);
}
}
}
and have your HTML tag look something like (not sure if syntax is
correct)
echo $html->hidden('Country/region_id', array( 'value' =>
$html->tagValue('Country/region_id'));
I use the parameters as "suggestions" for what values should be
defaulted to when the page opens. You can then still display a select
box for the region if you'd like the user to change it to something
else, or continue using the hidden value and just display the text
using the $html->tagValue().
