zend framework 3 segment routing doesn't work - php

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 ;)
