Question

In symfony2 I used config yaml below:

// config.yml
parameters:
  something: 
    content: 
      price:  2.30
      mainText: 'Some text here.'
      redText:  'This is a text here plus price: ' %price%

The %price% is wrong and gives me an error but system tells its an array, so how to point to something[‘content’][price]?

Answer 1

Here’s how you can do it

parameters:
    something.content.price: 2.30
    something:
        content:
            mainText: 'Some text here.'
            redText:  'This is a text here plus price: %something.content.price%'

Here we only have 2 parameters, something.content.price that contains a float, and something that contains an array.

This means you will only be able to access directly those 2, inside the DI configuration.
