Say I have a app/config/parameters.yml which contains
parameters:
database_driver: pdo_mysql
...
nacho_image:
upload: true
progress: false
key: secret_id
Now, I would like to get upload, progress, key in my controller, but doing
$this->get('upload');
$this->get('nacho_image.upload');
$this->get('nacho.image.upload');
$this->getParameter('nacho.upload');
$this->getParameter('acho_image.upload.upload');
doesn't work...
You cannot directly get a nested parameter. you have to get the parent key and you will get all the content as an array
$nachoImageConfig = $this->getParameter('nacho_image');
$nachoImageUpload = $nachoImageConfig['upload'];
From the doc (http://symfony.com/doc/current/service_container/parameters.html):
The used . notation is just a Symfony convention to make parameters easier to read. Parameters are just flat key-value elements, they can't be organized into a nested array
That is why in most config files, the entries under 'parameters:' are fully qualified like this:
parameters:
...
nacho_image.upload: true
nacho_image.progress: false
nacho_image.key: secret_id
You're getting this error, because your .yml file isn't well formatted. Your nacho_image parameter isn't within the range of the parameters part, but on the same level, so you can't access it over the parameters.
Edit your parameters shown as below, then you can access your parameters.
parameters:
database_driver: pdo_mysql
...
nacho_image:
upload: true
progress: false
key: secret_id
For everything else look @CROZET's answer.
If you need to access an value from the config, that isn't set within the parameters section, you could do it the way that is described in this answer.
