Do you really need to include that in the URL anyway? Could you just
present an empty form and have the user fill it in?

Good for what? Router::url() returns a string.You're not echoing nor
assigning the return value to anything.

First, get passing it to the controller action sorted out. Then you
can assign it to a view variable and pass that to FormHelper.

Start with the route:

Router::connect(
'/links/add/:url',
array(
'controller' => 'links',
'action' => 'add'
),
array(
'url' => '^http\://[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(/\S*)?$',
'pass' => array('url')
)
);

You may need to adjust the regexp to suit your requirements.

public function add($url = null)
{
if (!empty($this->data))
{
...
}

$this->set(compact('url'));
}

echo $this->Form->input('Link.url', array('value' => $url));
