zend framework 3 segment routing doesn't work

Question

I have the following module.config.php :

return [
    'router' => [
        'routes' => [
            'landingpage' => [
                'type' => Segment::class,
                'options' => [
                    'route' => '/landingpage[/:action/:id]',
                    'constraints' => [
                        'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
                        'id' => '[a-zA-Z0-9_-]*'
                    ],
                    'defaults' => [
                        'controller' => Controller\LandingPageController::class,
                        'action' => 'index'
                    ]
                ],
                'may_terminate' => true,
            ]
        ]
    ],
    'controllers' => [
        'factories' => [
            Controller\LandingPageController::class => LandingPageControllerFactory::class
        ]
    ],
    'service_manager' => [
        'invokables' => [
            'LandingPage\Service\LandingPageService' => 'LandingPage\Service\LandingPageService'
        ]
    ]
];

I am trying to use the following route and it doesn't work:

http://localhost:8081/landingpage/show/1CGe2cveQ

If I use the following route it works :

http://localhost:8081/landingpage/show

If I use the previous route with a / it doesn't work:

http://localhost:8081/landingpage/show/

If you need more info let me know. Thanks.

Answer 1

You have a double slash in the route declaration: the route is matched by /landingpage/ followed by /:action/:id. If you remove this double slash, the route will work as expected.

'route' => '/landingpage[/:action/:id]',

Moreover, I'd suggest you to modify the route declaration to make the id optional:

'route' => '/landingpage[/:action[/:id]]',
'constraints' => [
    'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
    'id' => '[a-zA-Z0-9_-]+'
]

Tested: config

'landingpage' => [
    'type' => Segment::class,
    'options' => [
        'route' => '/landingpage[/:action[/:id]]',
        'constraints' => [
            'action' => '[a-zA-Z][a-zA-Z0-9_-]*',
            'id' => '[a-zA-Z0-9_-]*'
        ],
        'defaults' => [
            'controller' => Controller\IndexController::class,
            'action' => 'index'
        ]
    ],
    'may_terminate' => true,
],

IndexController:

public function indexAction () {
    print '<pre>' . print_r($this->params()->fromRoute(), true);
    die(); 
}
public function showAction(){
    print '<pre>' . print_r($this->params()->fromRoute(), true);
    die();
}

Calling /landingpage

Array
(
    [controller] => Application\Controller\IndexController
    [action] => index
)

Calling /landingpage/show

Array
(
    [controller] => Application\Controller\IndexController
    [action] => show
)

Calling /landingpage/show/1CGe2cveQ

Array
(
    [controller] => Application\Controller\IndexController
    [action] => show
    [id] => 1CGe2cveQ
)

Don't forget to clear the configuration cache, if it enabled ;)
