How to create a custom yaml config file in Symfony

Question

What I want to do is quite simple: store data in a custom config file that I want to read later on.

I created my file something.yml that I put in the global

Answer 1

It's really easy, but also a little bit hacky:

Create the file /config/config_handlers.yml and add this:

config/something.yml:
  class:    sfDefineEnvironmentConfigHandler
  param:
    prefix: something_

Then add these two lines to /web/index.php after ... getApplicationConfiguration() (and also add them to frontend_dev.php and wherever you want this config file to be available):

$configCache = new sfConfigCache($configuration);
include($configCache->checkConfig('config/something.yml'));

So your /web/index.php might look like this afterwards:

checkConfig('config/something.yml');
sfContext::createInstance($configuration)->dispatch();

Btw: This is also in the documentation you cited, although the checkConfig() call is in a different place. Look for this: "When you need the code based on the map.yml file and generated by the myMapConfigHandler handler in your application, call the following line:"

Have fun ;-)
