I'm new to Zend Framework 2 and i want to learn this framework. I want to create url aliases in router. For example, I have defined something like this in module.config.php
'router' => array(
'routes' => array(
'home' => array(
'type' => 'Zend\Mvc\Router\Http\Literal',
'options' => array(
'route' => '/',
'defaults' => array(
'controller' => 'Application\Controller\Index',
'action' => 'index',
),
),
),
'node' => array(
'type' => 'Application\Controller\AliasSegment',
'options' => array(
'route' => '/node[/:id]',
'constraints' => array(
'id' => '[0-9]+'
),
'defaults' => array(
'__NAMESPACE__' => 'Application\Controller',
'controller' => 'Index',
'action' => 'index',
'id' => '0'
),
),
'may_terminate' => true,
),
),
),
When i type www.myapp.local/node/1
it routes to the default action in default controller of my application. What i want is a router extension that can handle aliases for url paths. For example:
www.myapp.local/node/1 = www.myapp.local/aboutus
www.myapp.local/node/2 = www.myapp.local/company/gallery
I know that it was possible in ZF. Here is a link to tutorial how to achieve this in ZF: friendly urls I know that this is in Polish but code is self-explanatory i think :)
The idea is to use url helper to assembly valid url using aliases or normal segments (node/[:id])
I've already created AliasSegment class in my Application\Controller folder but it shows me an error:
Fatal error: Uncaught exception 'Zend\ServiceManager\Exception\ServiceNotFoundException' with message 'Zend\ServiceManager\ServiceManager::get was unable to fetch or create an instance for Application\Controller\AliasSegment' in C:\xampp\htdocs\industengine\vendor\zendframework\zendframework\library\Zend\ServiceManager\ServiceManager.php:450 Stack trace: #0
My AliasSegment class (incomplete):
<?php
namespace Zend\Mvc\Router\Http;
use Traversable;
use Zend\Mvc\Router\Exception;
use Zend\Stdlib\ArrayUtils;
use Zend\Stdlib\RequestInterface as Request;
class AliasSegment extends Segment
{
public function match(Request $request, $pathOffset = null)
{
}
}
I was looking for an answer for hours and i couldnt find anything. Please tell me at least what I'm doing wrong, where to insert a code or maybe You know better sollution?
I'm not looking for ready application. I want to learn something but i would appreciate if You can tell me an answer in details :)
Thanks in advance and sorry for my English :)
EDITED:
My custom router is working now. At this moment aliases are hardcoded but it works.
My AliasSegment class looks now:
<?php
namespace Application\Controller;
use Traversable;
use Zend\Mvc\Router\Exception;
use Zend\Stdlib\ArrayUtils;
use Zend\Stdlib\RequestInterface as Request;
use Zend\Mvc\Router\Http;
class AliasSegment extends \Zend\Mvc\Router\Http\Segment
{
public function match(Request $request, $pathOffset = null)
{
$uri = $request->getUri();
$path = $uri->getPath();
//sample logic here
//for /about/gallery uri set node id to 1
//todo: get action, controller and module from navigation
if($path == '/about/gallery'){
$uri->setPath('/node/1');
$request->setUri($uri);
}
return parent::match($request, $pathOffset);
}
protected function buildPath(array $parts, array $mergedParams, $isOptional, $hasChild)
{
if(isset($mergedParams['link'])){
return $mergedParams['link'];
}
return parent::buildPath($parts, $mergedParams, $isOptional, $hasChild);
}
}
In this case /about/gallery
is an alias to /node/1
. Both adresses are correct. The buildPath function returns alias path correctly. Well, I hope this would be usefull for somebody :)
However i want to setup it in Zend_Navigation with additional parameter named 'link'.
I've done 50% of what i want to achieve however now I have problem to get Zend_Navigation from my router. I don't know how to pass it. I guess it should be something like this:
$sm = $this->getServiceLocator();
$auth = $sm->get('Navigation');
It works in my IndexController but doesnt work in my AliasSegment. I need to find in navigation array nodes with 'link' parameter.
EDIT
I've found solution. The answer is below.
