[FIXED] CakePHP3 routing: pass static variable to controller action

Issue

I trying to pass "language" param from CakePHP3 route, to the action, so I can set the language for those pages.

$routes->connect('/es/hola', ['controller' => 'StaticPages', 'action' => 'welcome']);
$routes->connect('/en/hello', ['controller' => 'StaticPages', 'action' => 'welcome']);

The only way I can make it work is using a dynamic parameter like this:

$routes->connect('/:lang/hola', ['controller' => 'StaticPages', 'action' => 'welcome'], ['pass' => ['lang']]);

But the problem is this route will be match:

/en/hola
/es/hello
...
/fr/hello

I think it should be another best way to do this in CakePHP3, but I can't find this.

Thanks!

Solution

If you don't want it to be dynamic, then you need to pass it in the defaults, ie alongside the controller and action:

$routes->connect(
    '/es/hola',
    [
        'controller' => 'StaticPages',
        'action' => 'welcome',
        'lang' => 'es'
    ]
);

In the controller the parameter will be available via the request object:

$lang = $this->request->getParam('lang'); // param('lang') before CakePHP 3.4

If you want it to be passed as an argument to the controller action, you can still define it to be passed via the pass option.
