ZF2 Child route issues - php

Question

I am trying to get some basic routing done in ZF2 but I am running into some problems.
The section that is giving me trouble is this:
'parent-categories' => array(
'type' => 'literal',
'options' => array(
'route' => '/kategorier/',
'defaults' => array(
'controller' => 'categories',
'action' => 'parent-categories',
),
),
'may_terminate' => true,
'child_routes' => array(
'child-categories' => array(
'type' => 'segment',
'options' => array(
'route' => '/kategorier[/:slug][/:parentCategoryid]/',
'constraints' => array(
'parentCategoryid' => '[0-9]+',
),
'defaults' => array(
'controller' => 'categories',
'action' => 'child-categories',
)
),
),
),
),
The original 'parent-categories' route works just fine, no problem. The problem though is the child-categories route isn't doing anything. I have the URL:
/kategorier/test-test-test-test-test/1/
but this is never matched to anything. I get the error:
The requested URL could not be matched by routing.
If I take the child-categories route out of the "child_routes" section, it always catches the request, even if the url is only /kategorier/. Can anyone see what I am doing wrong here?

Answer 1

A child route appends to the parent route. I.e. what you're currently matching is
/kategorier//kategorier[/:slug][/:parentCategoryid]/
Do it like this
'parent-categories' => array(
'type' => 'literal',
'options' => array(
'route' => '/kategorier',
'defaults' => array(
'controller' => 'categories',
'action' => 'parent-categories',
),
),
'may_terminate' => true,
'child_routes' => array(
'child-categories' => array(
'type' => 'segment',
'options' => array(
'route' => '[/:slug][/:parentCategoryid]',
'constraints' => array(
'parentCategoryid' => '[0-9]+',
),
'defaults' => array(
'controller' => 'categories',
'action' => 'child-categories',
)
),
),
),
),
And i guess this should be working out alright. It's a good advice to NOT have trailing slashes, as you'd ideally always want to begin new routes with one for better readability ;)
