Symfony2: There is no extension able to load the configuration for

Question

I am building an extension to load config files from all installed bundles.

my Extension looks like this:

namespace Acme\\MenuBundle\\DependencyInjection;
         


        

Answer 1

That's because your code:

$rootNode = $treeBuilder->root('mw_menu'); 

$rootNode
    ->children()
    ->scalarNode('mw_menu')->defaultValue('')->end()
    ->end();

means that the config file should look like this:

mw_menu: 
    mw_menu: "some teststring" 

---

An example:

To be more specific, you need to adapt your code to whatever node you want. In general, people use a general root, like mw_menu, and then secondary value like database_driver in the following example:

$rootNode = $treeBuilder->root('mw_menu'); 

$rootNode
    ->children()
    ->scalarNode('database_driver')->defaultValue('orm')->end()
    ->end();

Which would then look like this in config file:

mw_menu: 
    database_driver: mongo_db
