How can I access a GET request in CAKEPHP?

Question

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 ?

Solution 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.

Solution 2

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'];

Solution 3

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')

Thanks Dude... Shall i avoid to use $_GET in cakephp?

@cakephp.saint Yeah, I typically don't access $_GET or $_POST directly when i'm working in Cake. I just updated my answer with a link to the manual.

Thank you. Rescue comes sometimes no in the first, but the second post :D

Or even $this->request->query('page'); instead of $this->request->query['page'];

[I Wanna Know]

Is it needed: if ($this->request->is('get')){ $this->request->query['page'];}

[I Wanna Know]

Or can I just: $this->request->query['page'];
