Issue with template helper

[althaus]

Hey,

I just updated my vendors for the latest SonataAdminBundle and therefore also the BlockBundle was checked out. Trying to build the cache I'm getting this weird error:

PHP Fatal error: Can't inherit abstract function Twig_ExtensionInterface::getName() (previously declared abstract in Symfony\Component\Templating\Helper\HelperInterface) in /usr/share/iserv/symfony/vendor/sonata-project/block-bundle/Sonata/BlockBundle/Twig/Extension/BlockExtension.php on line 17

I don't understand the message as it's implying that one abstract class extends a method from its parent abstract class.

Edit: After another look I found that both Twig_ExtensionInterface and the inherited Symfony\Component\Templating\Helper\HelperInterface require a getName() method.

Cheers
Matthias

I have made a PR to fix this #83

Using this PR results in another error in SonataAdminBundle. Trying to access your admin dashboard returns this error: An exception has been thrown during the rendering of a template ("Warning: call_user_func_array() expects parameter 1 to be a valid callback, class 'Sonata\BlockBundle\Templating\Helper\BlockHelper' does not have a method 'renderBlock' in C:\wamp\www\Project\app\cache\dev\twig\16\5f\1b0eed585d7af7065254af4c935d.php line 54") in SonataAdminBundle:Core:dashboard.html.twig at line 21.

Sorry, I did not know it was merged. Everything is fine.

I still get this exception in production while

php app/console cache:warmup --env=prod --no-debug

PHP Fatal error:  Can't inherit abstract function Twig_ExtensionInterface::getName() (previously declared abstract in Symfony\Component\Templating\Helper\HelperInterface) in /var/www/html/shared/vendor/sonata-project/block-bundle/Sonata/BlockBundle/Twig/Extension/BlockExtension.php on line 17

Me too...

I just installed the Sonata Project Admin bundle and after clearing the cache, I get the following error message:

FatalErrorException: Compile Error: Can't inherit abstract function Twig_ExtensionInterface::getName() (previously declared abstract in Symfony\Component\Templating\Helper\HelperInterface) in C:\www\test4\vendor\sonata-project\block-bundle\Sonata\BlockBundle\Twig\Extension\BlockExtension.php line 17

This only happens after I install the bundle. I was able to clear cache with no error prior to installing the bundle. Not sure what to do, but obviously cannot use the bundle if this error exists. Any help?

[rmsint]

Not sure what happens in your case, I have seen discussions about this but it should be solved by now. Are you sure you run the latest code?

The issue is coming from php version < 5.3.8 where one class implements 2 interfaces which hold the same method name. The issue has been fixed in the master branch.

I will create a new tag ASAP

[buskaiwa2006]

Thanks. I am running the most recent code. Just a note that I was able to install the sonata-sandbox with no problem.

This issue still persists for me.

I have the following installed:

    "sonata-project/admin-bundle": "*",
    "sonata-project/doctrine-orm-admin-bundle": "*",

Can't inherit abstract function Twig_ExtensionInterface::getName(): Have this error on deployment server. Error does not exist on dev box. Using same code including composer.lock.

Code works on: PHP 5.3.10-1ubuntu3.6
Code fails on: PHP 5.3.3 (Redhat)

[rande]

@czarcar this has been fixed on 2.2.6, update your dependencies

[czarcar]

Thank you. FYI upgraded PHP on server last night to 5.3.27 problem went away.

Just updated to Sonata/BlockBundle 2.2.6 and I still get this problem. I'm on PHP 5.4.4. Any idea?
