Cakephp How to retrieve data from GET submit

Question

I'm passing a search data on method GET like that:

example.com/posts/?q=foo

I'm trying retrive this data on controller doing this:

$this->params['q'];

but is not working.

Answer 1

Looks like you're using CakePHP 1.3. If the submission was made using Cake's Form Helper, it should be something like..

$this->params['data']['q']

or if you explicitly wrote your own HTML code for the form,

$this->params['url']['q']

Answer 2

CakePHP specifice function for accessing query strings:

$this->request->query['q'];

Answer 3

CakePHP has simple helpers that let you access parameters.

For GET parameters you can use:

/users/search?age=23
$this->request->query['age']; // 23

---

For POST parameters you can use:

$this->request->data('age'); // 23
