How can I access a GET request in CAKEPHP ?

If I am passing a variable in the url

http://samplesite.com/page?key1=value1&key2=value2

Should I use $_GET or $this->params to get the values in controller? What is the standard in CAKEPHP ?

回答1:

The standard way to do this in Cake is to use $this->params.

$value1 = $this->params['url']['key1'];
$value2 = $this->params['url']['key2'];

According to the CakePHP book, "the most common use of $this->params is to access information that has been handed to the controller via GET or POST operations."

See here.

In CakePHP 2.0 this appears to have changed. According to the documentation you can access $this->request->query or $this->request['url'].

// url is /posts/index?page=1&sort=title
$this->request->query['page'];

// You can also access it via array access
$this->request['url']['page'];

And now that we have CakePHP 3; you can still use $this->request->query('search') in your views.

And in CakePHP 3.5 + you can use $this->request->getQuery('search')

You can do this only to get URL params,

$this->request->pass;  //Array of all parameters in URL
