how to access parameters from url in cakephp 3

Question

In cook book of cakephp 3. It is given to build url using

echo $this->Url->build([
    "controller" => "Posts",
    "action" => "view",
    "foo" => "bar"
]);

which will output as

/posts/view/foo:bar

How to access the foo:bar in action and save in a variable $foo ?

are you sure you are using cake3? cake 3 would return /posts/view/?foo=bar. Seems a cake2 application — arilia

@arilia check this http://book.cakephp.org/3.0/en/views/helpers/url.html#generating-urls — Anuj TBE

I guess is an error in the documentation or maybe the recently changed it. Did you try your code? I just tried your exact code in a cake3.2.13 application and it gives /posts/view/?foo=bar as expected. Anyway @JacekBBudzyñski comment is correct — arilia

there's an error in the cookbook, so I opened this ticket

if you use this code

echo $this->Url->build([
    "controller" => "Posts",
    "action" => "view",
    "foo" => "bar"
]);

you'll get an url like this

/posts/view/?foo=bar

the manual here explains how to access the GET parameters

you can do

$this->request->query('foo');

or

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

the first is null safe, it means that if the 'foo' parameter is not set you simply get null and not an error

Edit

after 3.4.0 the new syntax is

$this->request->getQuery('foo');

CakePHP 3.* version can use request Query :

$this->request->getQuery('utm_source')

Or in one line to get all the params as an Array:

$params = $this->request->getQueryParams();
