Just started building an app with the zend framework. I've working on a zend server 5.5. When I try to open the first controller I created, I get the following error message:
Application Error
Message: Action Helper by name EntityManager not found
Stack trace:
#0 c:\Program Files (x86)\Zend\ZendServer\share\ZendFramework\library\Zend\Controller\Action\HelperBroker.php(293): Zend_Controller_Action_HelperBroker::_loadHelper('EntityManager')
...
My guess is that I'm missing a library, but I'm not sure which one. Anyone know?
Where do you register the Helper?
Do you register the helper in the Boostrap or in the application.ini?
Where is the helper located? Please try to give more information concering that.
Anyways, it looks like you are using a standard setup, so you have to register the /path/to/your/helper with the Action Helper Broker.
For indepth information check the documentation
Check the class name of your helper file. The name must be something like this:
Zend_Controller_Action_Helper_helperfilename
This had worked for me.

I am beginner to play scala framework. And I have created simple CRUD operation using it.
In my routes file I have declared all the necesary urls for different actions.
I want to know if user input some wrong url path from browser How should I display error page in play scala? Right now I am getting all the routes which are already defined.
I just found a solution for it
https://www.playframework.com/documentation/2.8.x/ScalaErrorHandling
this is the latest play scala documentation which handles such type of condition.
Since I am using runtime dependency injection (e.g. Guice), the error handler can be dynamically loaded at runtime.
The simplest way is to create a class in the root package called ErrorHandler that implements HttpErrorHandler.
If you place your error handler in the root package (i.e. package-less) and name it ErrorHandler, Play will use it by default.
But, in case you want to:
Add it inside a package;
Configure different error handlers for different environments;
Then add in application.conf the configuration property play.http.errorHandler pointing to your custom error handler class:
play.http.errorHandler = "com.example.ErrorHandler"
I am currently trying to write a Hook to add extra fields to a Flexform. Therefore I followed this tutorial: https://docs.typo3.org/typo3cms/extensions/news/DeveloperManual/ExtendNews/ExtendFlexforms/Index.html?fref=gc&dti=250938618364487#extend-flexforms-with-custom-fields
But when I go to a page in the backend that contains an options from a Flexform I get the following Error:
Class 'ID\SearchBarAdditional\Hooks\FlexFormHook' not found.
I register the Hook in the ext_localconf like this:
$GLOBALS['TYPO3_CONF_VARS']['SC_OPTIONS'][\TYPO3\CMS\Core\Configuration\FlexForm\FlexFormTools::class]['flexParsing'][] = \ID\SearchBarAdditional\Hooks\FlexFormHook::class;
and my Hook-file is here: typo3conf/ext/search_bar_additional/Classes/Hooks
and is initialized that way:
namespace ID\SearchBarAdditional\Hooks;
class FlexFormHook { /* ... */
So in my opinion everything is in the right place and should work, but I do still get the error that TYPO3\CMS\Core\Utility\GeneralUtility::makeInstance("ID\SearchBarAdditional\Hooks\FlexFormHook") fails.
Do you guys have any ideas, what could be wrong? Do I have to register the Hook in \TYPO3\CMS\Extbase\Utility\ExtensionUtility::configurePlugin( or something similar (as the posted code is really the only thing I've done)?
This is a typical class loading error. Check that you added your PHP namespaces to composer autoloading and/or ext_emconf.php and make sure your filenames are correctly named according to PSR-4. If in doubt you can inspect the class loading map files generated by composer in vendor/composer (if you use composer for class loading, which you definitely should do).
I found the mistake: My Hook does indeed not get loaded. I tried to 'include' it in the ext_localconf.php and it is working now.
But as this is of course an extremely ugly solution I posted a second question, how to load a hook here: Typo3 8.X - autoload Hook
Thank you for your help!!!
I'm creating a restful api with grails 3.0.9 but if I generate the controller through the command line with: grails generate-controller [domain]
then my application will give an Grails runtime exception when I make a call to the api.
If I in the other hand create the controller manually (which extends the RestfulController) then there are no problems. I would like to get the controller generated so I can do some checks in save(), delete() and update()
This is the exception that I get:
ERROR org.apache.catalina.core.ContainerBase.[Tomcat].[localhost].[/].[grailsDispatcherServlet] - Servlet.service() for servlet [grailsDispatcherServlet] in context with path [] threw exception [Could not resolve view with name 'index' in servlet with name 'grailsDispatcherServlet'] with root cause
javax.servlet.ServletException: Could not resolve view with name 'index' in servlet with name 'grailsDispatcherServlet'
at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1227) ~[spring-webmvc-4.1.7.RELEASE.jar:4.1.7.RELEASE]
at org.springframework.web.servlet.DispatcherServlet.processDispatchResult(DispatcherServlet.java:1027) ~[spring-webmvc-4.1.7.RELEASE.jar:4.1.7.RELEASE]
It looks like it is trying to send the result to a view that does not exist, I should not need to create specific views for my rest api since it should only reply with the http status codes and some JSON.
Is this a bug or is the command generate-controller not designed for this?
I suspect you are generating a request that doesn't specify a format and doesn't specify an Accept header. If one of those is used to indicate that you want a JSON response, the default generated controller will respect that.
The project at https://github.com/jeffbrown/generatedcontroller demonstrates that the default generated controller with Grails 3.0.9 seems to work fine without any views.
What I an recommend is for you to install the templates and customize it so that it would produce a proper Restful controller.
I'm new to Zend framework, and was trying out the Guestbook tutorial that Zend has on it's web site. I have the latest framework downloaded and setup properly; php.ini include_files has the library location set correctly. In the Guestbook tutorial, the GuestbookController extends Zend_Controller_Action and that's what I typed, but I keep getting error stating that Zend_Controller_Action is not found. Turns out, the folder Controller is missing from /library/Zend. I tried re-downloading Zend Framework thinking I might have accidentally deleted it, but it's not in the newly downloaded framework directory either. So, where can I get the Controller folder that contains all the required class files? Or how can I fix the issue? Any help is much appreciated.
Thanks

It sounds like the tutorial you are following is for ZF1. ZF2 was released last year and works quite differently. You might want to try the quickstart from the current manual instead:
http://framework.zend.com/manual/2.0/en/user-guide/overview.html
Alternatively you can still download version 1.12 from the Zend site.
I downloaded the latest version of Zend framework, added a controller and I
can not get it to load.. Here is what I did:
C:\zend\Apache2\htdocs>zf create project myproject
Creating project at C:/zend/Apache2/htdocs/myproject
Note: This command created a web project, for more information setting up your V
HOST, please see docs/README
C:\zend\Apache2\htdocs>cd myproject
C:\zend\Apache2\htdocs\myproject>zf create controller mycontroller
Note: The canonical controller name that is used with other providers is "Mycont
roller"; not "mycontroller" as supplied
Creating a controller at C:\zend\Apache2\htdocs\myproject/application/controller
s/MycontrollerController.php
Creating an index action method in controller Mycontroller
Creating a view script for the index action method at C:\zend\Apache2\htdocs\myp
roject/application/views/scripts/mycontroller/index.phtml
Creating a controller test file at C:\zend\Apache2\htdocs\myproject/tests/applic
ation/controllers/MycontrollerControllerTest.php
Updating project profile 'C:\zend\Apache2\htdocs\myproject/.zfproject.xml'
C:\zend\Apache2\htdocs\myproject>
Then I tried to hit the controller from the browser..
http://localhost/myproject/public/mycontroller/
and I get the error: Not Found
The requested URL /myproject/public/mycontroller/ was not found on this server.
I have no idea how to resolve this, and I'm sort of shocked I'm having problems
with the Zend Server.
Dooh.. Actually the problem was quite simple.. I forgot the mod_rewrite.. Strange Zend didn't turn it on by default.
Check out the Zend Quick Start. It looks like you don't have the document root setup properly. Your request should have been http://localhost/myproject/mycontroller or http://myproject/mycontroller - if setup properly.
