view helper in zend framework 2 - zend-framework

the thing is these this lines:
$loginUrl = $this->view->url(array('controller'=>'auth', 'action'=>'index'));
$registerUrl = $this->view->url(array('controller'=>'register', 'action'=>'index'));
based on rob allens' Zend_Auth login/logout tutorial (win7/apache),
are placed in a view helper, and this one:
echo $this->url(array('controller'=>'index','action'=>'add'));
is placed in the index view script.
The generated links Do work fine in LOCAL, but in REMOTE only the 3rd line works.
ANY IDEAS? Where should i look for this? wich way to follow?
I was tempt to think in the remote server conf but the 3rd line works fine, so..
thanks!

Try this helper instead of view Zend_Controller_Action_Helper_Url:
//simple($action, $controller = null, $module = null, array $params = null)
//so your lines will look like:
$loginUrl = $this->_helper->url->simple('index','auth');
$registerUrl = $this->_helper->url->simple('index','register');
P.S. your lines work properly on Win7 and Ubuntu servers check registry of the lines

I found out that was the server. (.htacces and mod_rewrite) was not included in the package.
I think the third line was working because it was in the index controller, but when calling the others, then happened the object not found.
To work out this, i found an example using zend debug (was in german) so i inferred it (and then wrote to the hosting service), but still not quite sure how to check (phpinfo?) if a host have this features available or not in your package.

neo4jphp: Cannot instantiate abstract class Everyman\Neo4j\Transport

maybe a simple question but for me as starter with Neo4j a hurdle. I installed the neo4jphp with composer in the same directory as my application. Vendor-Subfolder has been created and the everyman/neo4j folder below is available. For a first test I used this code snippet from the examples:
spl_autoload_register(function ($className) {
$libPath = 'vendor\\';
$classFile = $className.'.php';
$classPath = $libPath.$classFile;
if (file_exists($classPath)) {
require($classPath);
}
});
require('vendor/autoload.php');
use everyman\Neo4j\Client,
everyman\Neo4j\Transport;
$client = new Client(new Transport('localhost', 7474));
print_r($client->getServerInfo());
I always stumple upon the error
Fatal error: Cannot instantiate abstract class Everyman\Neo4j\Transport
Googling brought me to a comment from Josh Adell stating
You can't instantiate Everyman\Neo4j\Transport, since it is an abstract class. You must instantiate Everyman\Neo4j\Transport\Curl or Everyman\Neo4j\Transport\Stream depending on your needs
So I thought I just need to alter the use-statements to
use everyman\Neo4j\Client,
everyman\Neo4j\Transport\Curl;
but this doesnt work, debugging shows, that the autoloader only get "Transport.php" instead of "everyman\Neo4j\Transport\Curl.php". For "Client.php" its still working ("vendor\everyman\Neo4j\Client.php") so I am guessing that the use-statement is wrong or the code is not able to handle an additional subfolder-structure.
Using
require('phar://neo4jphp.phar');
works fine but I read that this is deprecated and should be replaced by composer / autoload.
Anyone has a hint what to change or had the same problem?
Thanks for your time,
Balael
Curl is the default transport. You only need to instantiate your own Transport object if you want to use Stream instead of Curl. If you really want to instantiate your own Curl Transport, the easiest change to your existing code is to modify the use statement to be:
use everyman\Neo4j\Client,
everyman\Neo4j\Transport\Curl as Transport;
Also, you don't need to register your own autoload function if you are using the Composer package. vendor/autoload.php does that for you.
Thanks Josh, I was trying but it seems I still stuck somewhere. I am fine with using the default CURL - so I shrinked the code down to
require('vendor/autoload.php');
use everyman\Neo4j\Client;
$client = new Everyman\Neo4j\Client('localhost', 7474);
print_r($client->getServerInfo());`
The folder structure is main (here are the files and the composer.json with the content
{
"require": {
"everyman/Neo4j": "dev-master"
}
}
and in the subfolder "vendor" we have the "autoload.php" and the subfolder everyman with the related content. When I run the file I come out with
Fatal error: Class 'Everyman\Neo4j\Client' not found
which does not happen when I have the autoloadfunction. I guess I made a mistake somewehere - can you give me a hint?
Thanks a lot, B
Hmmm... I was just trying around and it seems the Transport CLASS is not needed in the use-statement and the class instantiation. This seems to work:
require('vendor/autoload.php');
use everyman\Neo4j\Client;
$client = new Client();
print_r($client->getServerInfo());
also valid for having a dedicated server/port:
$client = new Everyman\Neo4j\Client('localhost', 7474);
If you have more input I would be happy to learn more - thanks, all input & thoughts are very appreciated.

Zend_Session_SaveHandler_Interface and a session_id mysterie

I'm trying to setup my own Zend_Session_SaveHandler based on this code
http://blog.digitalstruct.com/2010/10/24/zend-framework-cache-backend-libmemcached-session-cache/
This works great, except that my session_id behave mysteriously.
I'm using the Zend_Session_SaveHandler_Cache class as you can find it in the blog above (except that I parked it in my own library, so it's name now starts with My_).
In my bootstrap I have:
protected function _initSession()
{
$session = $this->getPluginResource('session');
$session->init();
Zend_Session::getSaveHandler()->setCache( $this->_manager->getCache( 'memcached' ) );
}
To get my session going based on this code in my .ini file
resources.cachemanager.memcached.frontend.name = Core
resources.cachemanager.memcached.frontend.options.automatic_serialization = On
resources.cachemanager.memcached.backend.name = Libmemcached
resources.cachemanager.memcached.backend.options.servers.one.host = localhost
resources.cachemanager.memcached.backend.options.servers.one.port = 11213
So far so good. Until somebody tries to login and Zend_Session::rememberMe() is called. In the comments of Zend_Session one can read
normally "rememberMe()" represents a security context change, so
should use new session id
This of course is very true, and a new session id is generated. The users Zend_Auth data, after a successful log in, is written into this new session. I can see this because I added some logging functionality to the original class from the blog.
And here is where things go wrong. This new id isn't passed on the Zend_Session apparently, because Zend_Session keeps on reading the old id's session data. In other words, the one without the Zend_Auth instance. Hence, the user can no longer log in.
So the question is, how to make my saveHandler work with the new id after the regeneration?
Cheers for any help.
Ok, I'm blushing here....
I was looking at the wrong place to find this error. My session saveHandler was working just fine (so I can recommend Mike Willbanks his work if you want libmemcached session management).
What did go wrong then? Well, besides switching from file to libmemcached, I also switched from setting up my session in bootstrap to setting it up in my application.ini. So, instead of putting lines like
session.cookie_domain = mydomain.com
in my application.ini (which were then used in bootstrap as options to setup my session), I now, properly, wrote
resources.session.cookie_domain = mydomain.com
And this is were things went wrong, because.... I only changed those lines for production, I forgot to change them further down the ini file. In other words, my development env. got the cookie_domain of my production env., which is wrong as I use an other domain name during devolepment. So, on every page load, my cookie was invalidaded and a new session started. Mysterie solved...

Zend Framework unknown module is interpreted as default module

i wanted to support multilingual structure for my work i used the following lines
$controller=Zend_Controller_Front::getInstance();
$router=$controller->getRouter();
$languageRouter=new Zend_Controller_Router_Route(":lang/:module/:controller/:action", array("lang"=>"en","module"=>"default","controller"=>"index","action"=>"index"),
array("lang"=>"[a-zA-Z]{2}"));
$router->addRoute("default",$languageRouter);
it works fine http://localhost/zend/public/en set the lang param to en and call default module
but the problem is that when i use url like this http://localhost/zend/public/en/anything
where anything isn't module it still show the default module how to prevent that???
after the answer of takeshin i added this function to the bootstarp file and now it works as i want it
protected function _initRoutes()
{
$routeLang=new Zend_Controller_Router_Route(':lang',array('lang'=>'en'),array('lang'=>'[a-z]{2}'));
$front = Zend_Controller_Front::getInstance() /*$this->getResource('frontcontroller')*/;
$router = $front->getRouter();
$routeDefault=new Zend_Controller_Router_Route_Module(array(),$front->getDispatcher(),$front->getRequest());
$routeLangDefault=$routeLang->chain($routeDefault);
$router->addRoute('default',$routeLangDefault);
$router->addRoute('lang',$routeLang);
}
It looks like you have overwritten default module defined in Zend Application by your custom one.
You should chain the routes instead.
The settings you are using means module will 'default' to default , if you didn't it would throw a route not found error - which should throw to appropriate error controller
I'm not sure if I unterstood this correctly, but it looks like it works fine, as it should. If you try to call non existing module, Zend Framework automatically "redirects" to the default module.

Zend framework: how to migrate a site

I'm trying to copy a site built on ZF from production to a localhost environment. All files and db contents were copied but I just get a blank screen. No errors, nothing
Changes made in config.ini I added an entry for development:production
general.host = "localhost:8888"
db.adapter = PDO_MYSQL
db.params.host = localhost:8888
db.params.username = bla
db.params.password = bla
db.params.dbname = db_name
bootstrap.php
$frontController->registerPlugin(new Initializer('development'));
.htaccess contains a few basic directives but if I put some random stuff at the top I don't get Internal server errors so I don't think it even reaches the .htaccess stage.
Did I miss some kind of configuration somewhere?
EDIT:
I have code below in my bootstrap but still get a blank page. Very quickly, it barely loads at all
$frontController->registerPlugin(new Initializer('development'));
$frontController->throwExceptions(true);
// Dispatch the request using the front controller.
try {
$frontController->dispatch();
}
catch (Exception $exception)
{
exit($exception->getMessage());
}
Try adding this line before running dispatch() on front controller object.
$frontController->throwExceptions(true);
On production systems throwing exceptions is almost always disabled, enabling it on dev could tell you more about the nature of the problem.
Yes, you probably missed some configuration.
Try setting display_errors=On in php.ini. You should be able to see what is going on.
Also, like suggested - try putting $frontController->throwExceptions(true) before calling dispatch().
Regarding the .htaccess file - you need to put the AllowOverride All (or anything valid, other than None) in your apache.conf/vhosts config.

Dynamically setting view directory

I am making a customer portal application using ZF. And the portal needs to work for different company brands. So I need to use all of the same backend code/controllers/etc, but dynamically change the view directory based off of the hostname.
Right now my view directory structure looks something like this:
/application/views/scripts/brand1/
/application/views/scripts/brand1/index/index.phtml
/application/views/scripts/brand1/error/error.phtml
/application/views/scripts/brand2/
/application/views/scripts/brand2/index/index.phtml
/application/views/scripts/brand2/error/error.phtml
/application/views/scripts/brand3/
/application/views/scripts/brand3/index/index.phtml
/application/views/scripts/brand3/error/error.phtml
and so on.
I am using the addScriptPath() function in bootstrap.php like so
protected function _initView()
{
$view = new Zend_View();
$view->doctype('XHTML1_STRICT');
$view->env = APPLICATION_ENV;
$view->addScriptPath(APPLICATION_PATH . '/views/scripts/brand1');
$view->addHelperPath(APPLICATION_PATH . '/views/helpers');
...
}
However when this is run, it is looking for all views using /views/scripts/brand1/(action).phtml instead of looking for views using the correct scheme /view/scripts/brand1/(controller)/(action).phtml
tl;dr is it possible to dynamically choose the view directory and have it work like the default /views/scripts/(controller)/(action).phtml behavior?
I knew I would find the answer after I posted here. In case anyone else encounters the same problem, the solution was using:
$view->setBasePath(APPLICATION_PATH . '/views/brand1');
And then modifying the directory structure to:
/application/views/brand1/scripts/...
