Few days ago I have struggled with a problem using Symfony2 configuration. I wanted to add the following kind of configuration to config.yml:
acme_demo:
transitions:
- { hc_cba: 180 }
- { cba_hc: -1 }The problem was that the stuff under transitions is dynamic, so those hc_cba and cba_hc tags can be pretty much anything. After hitting many errors, I came to the solution:
<?php
$rootNode
->children()
->arrayNode('state_machine')
->requiresAtLeastOneElement()
->beforeNormalization()
->ifArray()
->then(function($values) {
$ret = array();
foreach ($values as $value) {
foreach ($value as $transition => $time) {
$ret[] = array('transition' => $transition, 'time' => e);
}
}
return $ret;
})
->end()
->prototype('array')
->children()
->scalarNode('transition')->end()
->scalarNode('time')->end()
->end()
->end()
->end()
->end()
;
