…dev, tech problems and solutions.
Ever wondered how to use the modulo operator in twig, the template engine of symfony?
Actually its like in PHP:
{{ 11 % 7 }}
As described here
But i guess for most use cases modulus is used to check if a number is divisible by another number.
Therefore Twig has the very conveniant divisible by test function.
{% if loop.index is divisible by(3) %}
We thought we had to improve our SilverStripe setup script for our development environment.
So Max and me rewrote it to add submodules and some other improvements.
Just run:
./install_silverstripe.sh mynewproject tags/2.4.7
and you have
Using MongoDB in your Silex Project is quite easy.
I will show this with my Superleansilexplate and will integrate it there as an example.
Since i dont want to integrate MongoDB in Superleansilexplate it will just become an additional gist.
Given you have some smaller amount of data like a counter that needs to be stored or other loose coupled datasets, we simply speak to MongoDB “directly” and store the data via Doctrine MongoDB Abstraction Layer.
Since i presume the Data / Document Structure isnt that complex we dont use Doctrine MongoDB ODM (the Object Document Mapper).
If you want to use it instead, try this Silex Extensions.
Alright, SilverStripe again, still our CMS of choice.
Today i’d like to promote a very helpful module that provides Register and Profile Pages for Members for the Frontend.
The memberprofiles module.
It comes with a lot of features and customize options for nearly everthing you might need for Frontend Member Handling.
Further it is fully extendible to customize it even more.
For a starter tutorial i recommend a very good post by deadlytechnology.
I would like to describe how you extend it.
First lets install it (with the orderable module dependency):

Caution: Scepticism ahead!
So i’d like to share some of my experiences in the cloud since i am still trying to figure out if it its worth for me or if i am better suited with an VPS.
Maybe somebody feels like feedbackin.
I tried PHPFog for PHP and no.de by joyent for node.js.
First i have to admit: yes i only tried the free models and of course they are limited and because its free you cant expect to get it all, right?
Yes and thats true.
With PHPFog i set up an app based on symfony 1.4. After some inital problems due to some bugs on PHPFog side, i got it running.
I really like to mention the kind and immediate chat support by PHPFog. It really made me feel like dealin with humans and not only machines. Big up!
By then everything felt really smooth with git deploy, configurations, mysql setup etc.
But i had to shut down the app again, because there are restrictions to PHP which killed the app like disabling “file_get_contents for remote URLS”, probably only in the free model. But that killed it for me at that point.
So read this carefully before going to cloud: http://docs.phpfog.com/index.php/features/article/shared_vs_dedicated
I guess with dedicated hosting you get more power, sure.
The HTTP_CACHE resp. the reverse proxy of Symfony is a pretty cool thing.
And as it is build-in Silex it can speed up the already fast micro framework massivly,
wich is good for me, as i am mainly workin with Silex right now.
To enable it you have to register it first like its shown in the docs:
$app->register(new Silex\Provider\HttpCacheServiceProvider(), array( 'http_cache.cache_dir' => __DIR__.'/cache/', ));
Also provide the writable cache dir.
Continue reading “Silex and the HTTP_CACHE”
UPDATE
Please have look here for a updated version.
Note: its about Twig-extensions not about the former “Silex Twig Extension”, this now called TwigServiceProvider.
First fetch the Twig-extensions code and put them in your vendor dir:
git submodule add git://github.com/fabpot/Twig-extensions.git vendor/Twig-extensions/fabpot git submodule init git submodule update
Then register the autoloader by using registerPrefixes:
$app['autoloader']->registerPrefixes(array(
'Twig_Extensions_' => array(__DIR__.'/../vendor/Twig-extensions/fabpot/lib')));
Well you can try to, but it will end up almost probably in an disconnect which is caused by the browser.
As i have learned here.
Given you have a string which contains invalid unicode like:
This will trouble the browser and the socket connection.
If you prepare your json with PHP and json_encode the Unicode will be escaped to some strings like these:
\ud83d\ude31\ud83d\ude31\ud83d\ude04\ud83d\ude04\ud83d\udc9c\ud83d\udc9c\ud83d\udc4a
But on clientside it will still result in invalid Unicode.

If you wonder about routing in OXID eshops or how the URL structure is here are some hints:
OXIDs MVC, well thats some kind of different naming and you have to get used to:
the M (Model) you find in /core
the V you find in in your templates in /out, there the main view is called the same as your controller, given the controller has a render() method.
/views/details => /out/[templatename]/page/details.tpl
the C (Controller) you find in /views (what? oyerywell!)
like /views/details.php
The routing itself is like so:
