Syntax

The function must be specified in a JSON format, which may contain one of the following 4 objects:

• String: { "something" }
• Function: One of the allowed functions above

  • Example (this will return current date in this format: 2014-12-08+09:38:

    {
        "function": "date",
        "args": [
            "Y-m-d+H:i"
        ]
    }
    

  • Example with a nested function (will return a date in the same format from 3 days ago):

    {
        "function": "date",
        "args": [
            "Y-m-d+H:i",
            {
                "function": "strtotime",
                "args": ["3 days ago"]
            }
        ]
    }
    

• A key from the parameters array:
  • { "attr": "attributeName" } for $params['attr']['attributeName']
  • or { "param": "nested.attribute.name" } for $params['param']['nested']['attribute']['name']
  • The first level is always used as the key to determine the "type"
