I writing plugin that allows using of "special codes".
On Gravity Form I want to allow people to define an input field named 'special_code' and then access it's value via validation filter from my code.
GF insists on "input_5" - type of names. Which means on some forms it will be "input_2", on others "input_8". Some people will name it on forms as "Code Specialle", and others as "Preferred code".
Then how do I find my "special code" field on submitted form to validate?
I couldn't find a way to set an input name for a field?
